quenching play the crucial role in controlling the mechanical properties of the steel bar such as yield strength. Hence understanding of the cooling system is essential. There are three types of most frequently used cooling system in hot rolling; water jet cooling system, water spray cooling system, and mist cooling systems.[3]It is
The T6 temper was used for cold or hot water quenching and the T61 temper is used when the products are quenched in boiling water. In instances where the boiling water quench is employed, the dimensional stability of the material is much more important than the strength level desired, so the strength has been saced for dimensional stability.

Continuous Annealing Line (CAL) This line facility changes the crystal structure of steel sheet by heat treatment, and improves properties such as hardness, strength, and elongation. It integrates the 5 processes of cleaning, cooling, heating, temper rolling, and refining, and carries them out in a single line, thus saving space and lowering costs.
ers. The rolling mill comprises a rough rolling mill (8 stands), intermediate rolling mill (8 stands), and fi nish rolling mill (2Hi type, 4 stands, 3roll SCFM type, 4 stands). Cooling zones, comprising waterfi lled tubes, are installed following these rolling mills. TQF® bar is a steel bar product which is produced by online quench
During this step, the part is submerged into some kind of quenching fluid; different quenching fluids can have a significant effect on the final characteristics of a quenched part. Water is one of the most efficient quenching media where maximum hardness is desired, but there is a small chance that it may cause distortion and tiny cracking.
Jul 13, 2015· Examples are coke quenching, cooling of blast furnace shell, oxygen lance in converter, cooling in continuous casting machines and hot rolling mills. Virtually any hot spot is cooled mainly by using water, one way or another. Water is used for cleaning offgas, in coke ovens, blast furnaces, and basic oxygen furnace etc.
