Water Cooling Flow Control on Hot Strip Mill - TMEIC

cooling tubes on a hot strip mill. Constant water level in the header tank produces a constant pressure at the flow control valves in the laminar flow lines and allows good flow control. If too much flow enters the header tank, the surplus water overflows into the scale water pit, and wastes pumping energy. P

Features of Hot Rolling and Controlled Cooling

Since the first laminar cooling system was used in Brinsworth’s narrow strip hot rolling mill in the 1960s, after 50 or 60 years’development, the controlled cooling technology has been applied in most of the output rollers at the rear of the hot rolling mill at home and abroad, and the cooling methods are also varied. At present, the commonly used …

How the Operations of Hot Rolling Mill Works | Deem Rolls

How does the operation of hot rolling mills works: The process starts with heating the billets and blooms at extremely high temperature, which is generally above 1100 C. Such higher temperature is the basic requirement for the procedure. To crack the grain structure of the metal and destruct the boundaries of the metal, the steel goes through ...

The present authors previously proposed a processing route that would allow for the production of Q&P microstructures directly off of the hot-strip mill,[] as shown schematically in Figure 1(b).Here, the quenching step is accomplished during run-out table cooling, similar to that in dual-phase steels (step cooling may be used prior to quenching if primary ferrite is desired).

What's the difference between hot and cold rolling mills?

After heating, the strip is made of cold rolling mill and hot rolling mill. The finished steel of hot rolling mill is cooled to laminar flow to establish temperature band. It is coiled in the coil by winding machine, and coil cooling is a finishing operation according to different needs. Users straighten the cross-section of leveling line.
