Types of Cold Rolling Mills (With Diagram) | Metals | Metallurgy

Like hot rolling, cold rolling can be done using two-and-four-high roll arrangements. Two types of cold rolling mills commonly used are: (i) Sendzimir mill (ii) Saxl pendulum mill Both of these mills make use of small diameter rolls. The former type makes use of elaborate system of backing rolls of increasing diameter as shown in Fig. 6.1. It will be noted that …

Hot Rolling Mill

Hot Rolling Mill The slabs cool outside before being reheated in the reheat furnace. The slab (210 mm thick and weighing over 10 tonnes) is then transferred into the reversing rougher mill and is reduced in thickness with each pass. The steel is rolled down to about 25 mm when it is coiled in the coil box (to retain heat). It then passes ...
