2. Introduction to the Turn Over Cooling Bed
What is a Turn Over Cooling
Bed?
A turn over cooling bed is a type of
conveyor system used to cool down
hot steel products in a controlled
way to reduce their temperature to
a certain level
Why is it important?
It is instrumental in bringing high-
temperature steel products down to
the desired temperature, so that it
can be transported for further
processing and also for ensuring
that it is not damaged or deformed.
Types of Turn Over Cooling
Beds
There are several types of turn over
cooling beds such as a fixed rake
cooling bed, chain cooling bed,
walking beam cooling bed, and lift
and swing cooling bed.
Total Output
The annual output of a turn over cooling bed for a steel making plant varies depending on the plant size and its production
capacity but typically ranges from 100,000 to 1,000,000 tons per year.

3. Working Principle of the Cooling Bed
How does it work?
The turn over cooling bed works by
transporting hot steel products from the
reheating furnace onto the cooling bed. The
steel products are then cooled down by the
air and water sprayed from the cooling
system while they travel to the discharge
end of the cooling bed.
The Cooling Process
During the cooling process, the hot steel
products are transported via rollers which
are situated on a sloping bed. The rollers
rotate at a slow pace to help reduce the
residual heat and cool the product to the
desired temperature.
Cooling Bed Components
A cooling bed is made from a system of
conveyor rollers, water spray system,
cooling fans, stoppers and spacers, end
ramps, and over turning devices to facilitate
the cooling process and transfer of the
steel products for further processing.

4. Features of the Cooling Bed
1 Robust Design
Cooling beds are designed to handle heavy loads,
making them an essential tool in the steel making
industry.
2
Modular Construction
A modular cooling bed design makes it easy to
assemble, disassemble and maintain the system,
saving time and money. 3 Fully Automated
Newer cooling beds feature smart automation and
safety, with automated control systems and
emergency stop features to prevent accidents.

5. Design and Construction of Cooling Bed
Material Cooling beds are made of durable materials such as rolled
steel sections or welded beams, which are strong and can
withstand high-temperature conditions.
Size The size and shape of the cooling bed can vary depending
on the plant requirements, with some cooling beds being
up to 250 meters long and 3 meters wide.
Construction The construction of a cooling bed is a complicated process,
and it must be carried out by expert technicians, following
detailed designs and specifications, to ensure that the final
product meets the highest standards.

6. Maintenance of the Cooling Bed
1 Regular Inspection
Regular inspections by trained
technicians are necessary to
detect and repair any wear and
tear issues before they become
more serious problems.
2 Cleaning and Lubrication
Cleaning and lubrication of the
cooling bed's components are vital
to prevent damage from rust and
corrosion.
3 Part Replacement
Replacing worn-out parts, such as
rollers, chains and gears, is
essential to avoid downtime and
maintain optimal performance
levels.
4 Operator Training
Proper operator training can
improve worker safety and also
reduce the need for extensive
repairs, replacements, and
maintenance.

7. Advantages of Using a Cooling Bed
Improved Product Quality
A controlled cooling process ensures
that the product maintains its shape,
size, and strength, making it easier to
process and preventing defects.
Increased Production
Efficiency
Cooling beds provide a way to safely
handle high-temperature steel
products, which can then be
transported and processed more
efficiently, reducing production time
and costs.
Enhanced Safety
Cooling beds are equipped with safety
features that prevent accidents, such
as emergency stop buttons, sensors,
and automatic shut-offs.

8. Conclusion
The turn-over cooling bed is a critical component of the steel-making
industry. By properly cooling steel products, it guarantees the quality and
durability of the finished product. The careful design, construction, and
maintenance of cooling beds is key to ensuring the longevity and safety of
these vital pieces of equipment.
