IRJET- Experimental Investigation on Partial Replacement of M-Sand by Steel SlagIRJET Journal
This study experimentally investigated the partial replacement of m-sand (natural sand) with steel slag as fine aggregate in concrete. Various concrete mixes were prepared by replacing m-sand with 10%, 20%, 30%, and 40% steel slag by volume. The compressive strength, tensile strength, and flexural strength of the concrete cubes, cylinders, and beams were tested and compared to a conventional concrete mix without steel slag. The results showed that replacing up to 30% of m-sand with steel slag did not negatively impact the strength of the concrete and can be a viable way to utilize an industrial waste product in construction.

Refractory brick contacted glass liquid in melting poolsunrise refractory
Refractory bricks used in glass melting pools are susceptible to corrosion from direct contact with molten glass. The liquid glass temperature can reach 1500°C, requiring refractory bricks with high corrosion resistance. Maintaining stability at the refractory-glass interface and preventing spalling are also important to avoid glass defects. Zhengzhou Sunrise Refractory is a manufacturer of refractory products for the glass industry, including fused cast bricks and mullite, zircon, and magnesia bricks.
Zirconium oxide plays an important role in glass refractory and it is an important chemical composition of zircon related refractory, such as fused cast azs block, zircon brick, fused cast high zirconia brick and zircon mullite brick . Zirconium oxide is a white crystalline which is difficult to dissolve in water, hydrochloric acid and dilute sulfuric acid. Zirconium oxide has the characteristics of high melting point, high resistance coefficient, high refractive index and low thermal expansion coefficient.
ZrO2 in zircon brick is about 65% which is almost composed of zirconite crystals and contains only a very small amount of glass phase and free ZrO2. The ture density is about 4.55g/cm3 or so, and the maximum ture density can reach 4.62 g/cm3. The bulk density of zircon is between 3.6 g/cm3 and 3.8 g/cm3, and apparent pososity is above 13%.
It is a normal phenomenon for fused cast azs block to have porosities when pouring, however, the existence of any porosity can directly reduce the quality of fused cast azs block. But where does the porosity come from? They are generally from four aspects: furnace material, melting process, casting material, and casting process.
Zircon brick is a refractory brick which is made by natural zirconite and through sintering method. During the production process, not only zirconite is used as the main raw material, while appropriate sintering agent (the most commonly used is refractory clay) is added into the raw material. In order to improve the property of zircon brick, other components are added into the material such as bauxite, corundum or chromium oxide.
Mullite brick is a new type refractory material of high efficient energy saving which can contact flame directly. Mullite brick is also a high alumina refractory material with mullite as the main crystalline phase, and the content of alumina is generally between 65% and 75%. As to chemical composition, except for mullite, glass phase and square quartz is contained if the content of alumina is low; corundum is contained if the content of alumina is high.
Zircon brick can especially be used as superstructure bricks of flame space and bottom bricks of glass furnace in glass industry.Zhengzhou Sunrise Refractory Co., Ltd can provide zircon brick with good quality which have passed the ISO international certified. With reliable quality, competitive price and prompt delivery, Sunrise has established long-term business and cooperation relationship with many customers in different countries and regions. For any further information, Contact us, Sunrise are sincerely looking forward to establishing a long-term mutually beneficial relationship with you.

Zircon brick is refractory product made of natural zircon. It has the advantages of strong slag resistance, high mechanical strength, high refractoriness under load, large abrasive resistance and excellent thermal shock stability, it is an important material for furnace construction in the industries, such as metallurgy, building materials and electronics, It is usually used in regenerator chamber, bottom part and side wall.
The document discusses factors that affect the anti-corrosive properties of fused cast AZS brick. It states that anti-corrosive properties allow the brick to resist corrosion from substances like slag, fuel, and acids at high temperatures. The chemical composition, density, porosity, and conditions of use all impact a brick's resistance to corrosion. Multiple factors together determine the complex anti-corrosive abilities of refractory bricks.
ZrO2 is the main oxide of zirconium, and it is a white crystalline which is difficult to dissolve in water, hydrochloric acid and dilute sulfuric acid. ZrO2 is an important material of refractory with the characteristics of high melting point, high resistance coefficient, high refractive index and low thermal expansion coefficient.
Features during casting process of fused cast azs blocksunrise refractory
The casting process has a significant influence on the quality of fused cast AZS blocks. During casting, intense heat exchange and chemical reactions occur between the molten liquid and sand mold. This can lead to issues like porosity if the cavity pressure increases too much. Uneven molten liquid flow may also cause defects on the surface of the blocks. How the molten liquid fills the porous mold wall further impacts the final internal structure, potentially causing air holes or sand inclusions. The time of the casting process also affects the temperature distribution within the finished block.

Glass furnace is a hot engineering equipment with high temperature, which is the main equipment and heart of glass industrial. In order to prolong the service life of glass furnace, increase the melting ability of glass furnace, and reduce energy consumption, besides the reasonable design of glass furnace structure and reasonable refractory(using different refractory in different part of glass furnace, for instance, fused cast azs block 33# is usually used in bottom, fused cast azs block 41# is usually used as throat and electrode brick ), manufacturing process is also in considering at the same time, as manufacturing process is not only related to the melting ability of glass furnace and glass quality, but also influencing the service life of glass furnace.
Glass furnaces must be designed and operated properly to prolong their service life. Key factors include using refractory materials suited for different furnace areas, maintaining stable and appropriate melting temperatures without large fluctuations, controlling the distribution of mineral materials to reduce corrosion, limiting impurities like iron in raw materials, and adding moisture to inhibit the generation of fly materials. Zhengzhou Sunrise Refractory provides high-quality refractory products and has experience helping customers prolong furnace lifetime through proper material selection and process control.
