Ladle furnace metallurgy means that the ladle refining furnace is used to refine the molten steel melted in the primary smelting furnace (electric arc furnace, open hearth furnace and converter), adjust the temperature of molten steel, buffer the process, and meet the requirements of continuous casting and continuous rolling. A ladle furnace is one of the main pieces of equipment for refining outside the furnace.
End splitting during long products rolling billet quality of rolling processJorge Madias
End splitting occurs because the material being rolled has not enough ductility to withstand the stress to which it is submitted. This may happens for different reasons. Coarse cracks in the billet end, like central or diagonal cracks, weakens the end, particularly when the plane where are located coincides in part with the symmetry plane between rolls. Hot ductility of steel depends on the one hand of their intrinsic features, and on the other hand, on the temperature at which they suffer the stress, and its speed.
It is important to roll the steel within the range of higher ductility at a given deformation speed. This is more critical for steels with inherent low ductility as those containing high sulfur.
The role of MnS stringers is also clear; having S controlled at the lower level of the specification is favorable. Nevertheless it is worth to mention that if caster condition is proper and excessive thermal/mechanical stresses do not arise, very high Mn/S ratio is not necessary.
Bar ends loss temperature faster. Another factor is roll cooling, it has to be correctly oriented, not excessive and keeping the position along the processing time.
In other factors experimental and modeling results are apparently controversial. There is coincidence in the fact that more friction between bar and rolls promotes splitting, but not in factors like roll diameter and reduction.
On the basis of pilot rolling results, plane, box-box, square to round and oval to round passes are favorable to avoid splitting, while oval to square promotes splitting.
Steel industries have been an integral addition to India’s economic scenario as they have not only added gross profit to the national fund but also have enhanced employment options significantly. There are many steels rolling mills manufacturers, steel plants suppliers and steel melting plants in India that makes up this particular industry. These steel rolling mill plants have become an important part of any steel industry. As steel is the most widely used metal in today’s world, it is an integral manufacturing material in number of industries.
TMT Bar should have the perfect combination of Strength and Flexibility. Otherwise it is not recommended for all type of construction purposes. Strength of TMT Bar enables load bearing capacity where Ductility helps to bend as per construction requirement also protect the buildings during an Earthquake.

Experimental and Microstructural Analysis of TIG and MIG Welding on Dissimila...Abu Sufyan Malik
In the modern era, most of the industries have a high demand of light weight, high strength structures with desired product properties which depend on the joining of dissimilar materials for manufacturing.
In TIG welding tungsten electrode is placed centrally in the torch. During the inert gas supplied through the annular space between torch and electrode, the filler material was supplied using a separate rod and shielding undertaken by covering the weld zone with a blanket of gases (Argon, Helium) which prevent the exposure of weld metal to oxygen and hydrogen of the air.
In MIG welding, the arc is struck between the work piece and the wire, which act as electrode and filler material, the arc and weld pool were shielded by inert gas. Depending upon the work material, the shielding gas may be argon, helium and carbon dioxide. In this case, the bare metal electrode (consumable electrode) in the form of continuous wire is fed through welding torch with the help of electrical motor and feed rolls.
Mild Steels are the carbon steels which generally contain less than about 0.60-1.4% wt of Carbon. The alloy of Mild Steel with Chromium, Magnesium, Vanadium, tungsten and Molybdenum are used as Knives, Razors, Cutting tool, dies, hacksaw blades and crankshaft. They typically have a yield strength of 430–585MPa (62–85 Ksi), tensile strengths 605-780 MPa (88–113 Ksi), and a ductility of 33–19%EL.
The stainless steels are highly resistant to corrosion in a variety of environments, especially ambient atmosphere. Their predominant alloying element is chromium; a concentration of at least 11 wt% Cr is required. They typically consist a yield strength of 205 MPa (30ksi) to 1650Mpa (240 Ksi), tensile strengths between 380 and 1790 MPa (55 to 260 Ksi), and a ductility of 20 to 40%EL. A wide range of mechanical properties combines with excellent resistance to corrosion making stainless steels very versatile in their applicability. Equipment employed for these steels includes gas turbines, high-temperature steam boilers, heat-treating furnaces, aircraft, missiles, and nuclear power–generating units.

There are thousands of different kinds of steel. Steel is the general name given to a large family of alloys of iron with carbon and a variety of different elements. Even small differences in the composition of the steel can have a dramatic effect on its properties. The properties of the steel can also be modified by different mechanical and heat treatments. Steel is such a versatile material because we can adjust its composition and internal structure to tailor its properties. So we can produce a steel for paperclips, thin strips of steel for razor blades, a steel for bridges and large beams for columns and skyscrapers. The volume of steel consumed has been the barometer for measuring development and economic progress. Considering a steel consumption of 300 kg per man per year to be a fair level of economic development for certain country/nation. Whether it is construction or industrial goods, steel is the basic raw material. Lighter metals and stronger alloys have been developed, plastics and synthetics have replaced steel in many areas. Hence, another major feature in the steel industry is the continuous improvement of steel grades. Half of today’s steel grades were not available ten years ago. Just take an example of the most commonly used steel – rods or bars, used as reinforcement material with cement concrete. It is used to be plain bars even in the sixties, then came the ribbed bars, followed by the twisted deformed bars and now it is thermo-mechanically treated bars. Each development has added to the strength of construction. Older varieties of steel have been improved upon and newer grades introduced. The process continues.
Steels are described as mild, medium or high-carbon steels according to the percentages of carbon, although is never greater than about 1.5 %. Adding metals such as nickel, chromium, etc to iron produces a wide range of alloy steels, for instance stainless steel.
The properties of steel are closely/strongly related to its chemical composition. For example, there is a big difference in hardness between the steel in a drinks can and the steel that is used to make a pair of scissors. The metal in the scissor contains nearly twenty times as much carbon and is many times harder. Changing in carbon content changes the properties of the steel and the way that it is used. The steel is more malleable as the carbon decreases. Generally, carbon is the most important commercial steel alloy. Increasing carbon content increases hardness and strength and improves hardenability. But carbon also increases brittleness and reduces weldability because of its tendency to form martensite. This means carbon content can be both a blessing and a curse when it comes to commercial steel.
Rolling process deforms the cast product into required shape. There are three groups of rolled long products namely bars, rods and sections. The hot-rolled flat products can have the form of plates, sheets or strips. Hot-rolled products are often subjected to further processing such as cold-rolling (for good surface finish), machining, etc. in order to achieve a variety of steel products. At further downstream, the hot-rolled plates can be processed to form longitudinal welded pipes of large diameter. Other principal hot rolling product groups that can be distinguished are seamless tube rolling, specialty products such as wheels, rings, etc.
The iron ore is heated up to about 900 °C, and as it descends down the shaft furnace, they are reduced. The reducing gas (with high concentration of H2 & CO) flows upwards and in countercurrent with the descending flow of iron ores by gravity. The H2 & CO reacts with the oxygen in the iron ore to become water vapor (H2O) and CO2 respectively, at the reduction zone. The reduced iron ore is therefore rich in metallic iron (M.Fe). At the cooling zone, the DRI is cooled down to 50°C by a mixture of natural gas and reducing gas and it is during this process where most of the carbon in the DRI is formed. The cooled DRI is then screened before sending to the meltshop for use. At the meltshop, scrap is charged into the Electric Arc Furnace. The scrap is melted to form a molten pool. DRI is then top fed into the molten steel and during this period, the temperature at around 1580°C. After DRI feeding is completed, molten steel sample and temperature are taken for analysis. Molten steel temperature is then raised to the required tapping temperature, and then tapped out from the Electric Arc Furnace into a ladle by forward tilting. After skimming, the ladle is placed on a ladle transfer car. The transfer car is then moved to a Ladle Furnace Station. At the Ladle Furnace Station, molten steel temperature and chemical composition are homogenized by bubbling. Final adjustment of chemical compositions and temperature are made before sending to the Continuous Casting Machine. The ladle is placed on a ladle turret. The ladle turret is then swung into casting position. The ladle sliding nozzle is then opened to allow molten steel into the tundish. Molten steel in the tundish is maintained at a certain level to regulate the required casting speed. The process of casting takes place in the copper mould which is indirectly cooled with water. Billet is cooled further directly by secondary spray cooling system. The billet strand is later cut by an oxygen torch to the required length as specified by the customer. From here, billets are transported by land to the Gurun Plant. The billets are then charged into the reheating furnace, after the checking for internal and surface defects. During the heating process, the surface of the billets tends to oxidize and forms scales. These are removed before the billets are used for the next process using descaler. The billets are then charged into a series of roll stands, where the billets will undergo a shaping process to reduce the diameter of the billets to the desired size. The specified final diameter determines the size and amount of roll stands the material has to go through.
Welding Electrode Grade: PS2007A – for Electrode Product Sdn. Bhd. (subsidiary of PNB). PS2007B – for MOX Bhd. It is noted with the small deviation on the chemical composition to suit with customer requirement w.r.t. different electrode fluxes/rod strength. Why low Si? - related to the influence of Si content on coating weight for good galvanizing and drawability. - & vs. influence to electrode fluxing.
Database records: Standard Steel Grade Specification for Billets – 115 records. Customer List – 38 records (exported to Vietnam, Taiwan, Philippines, Indonesia, Australia,etc. and recently to Iran (through Cargill). Standard Steel Grade Specification for Bloom and Beam Blank – 29 records.
Bar rolling is conducted in several passes. After each pass the cross-section of a stock is reduced and the shape of a stock more and more approaches to the shape of a final product. There are different types of hot-rolled bars commonly used such as round bars or deformed bars (produced at Gurun Plant), square bar, hexagon bar, etc.
Wire rod can be used as a starting material for production of a variety of products, such as wire, wire ropes, springs, bolts, nuts, nails, screws, bearings, tire cords, music wire, core wire of covered electrodes, etc.
