This CCM (Continuous Casting Machine) equipment is used to casting billet main products are, R3M, R4M, R6M, R9M, and R12M continuous casting machine with matching radius. It is composed of large steel ladle, middle steel ladle, crystallizer, vibration device, arc section, primary water cooling, secondary water cooling, dummy bar, billet pulling device, multipoint ...
High casting speeds in the range of 2 m/min to 4 m/min and width of 800 mm to 1600 mm is possible. The caster is connected to rolling mill via a roller hearth reheating furnace which equalizes the slab temperature to 1120 deg C. The rolling mill can include four, five, or six finishing stands depending on product mix and required finishing gauge.

Hot Billet Shear, automatic PLC cutting, inline with the CCM, for direct rolling
The reversing cold rolling mill is the allrounder among the cold rolling mills: Here, thin strips, thick strips, soft grades, highstrength and ultrahighstrength strips can be rolled in succession on one and the same plant. The RCM is mainly used for low carbon steels, but is also a good solution for modern grades such as silicon steels.
Hot rolling and hot extruding drawing involves working above the recrystallization point of the steel. The mill passes the heated material through a variable...
Cold rolling reduction is an important factor that affects drawability of IF steel. It has been observed that increasing cold rolling reduction increases the r m value, at least up to 90% [34].This effect has been shown in Fig. the most important parameters in the production of a strong {111} recrystallization texture are the annealing temperature and the time of holding [35].
