Cold reduction mill sheet and strip are cold reduced to the desired thickness for the following reasons to obtain the desired surface. to impart desired mechanical properties. to make gauges lighter than the hot strip mill can produce economically. to produce sheet and strip of more uniform thickness.
Cold reduction mills are controlled by process computers, and since tcrsss mill is one of the most advanced designs, coils are rolled to the closest dimensional tolerances. electrolytic cleaning tcrss employsighly efficient electrolytic cleaning system for removing the cold rolling lubricant from the strip.
Cold rolled product cold rolled product is made from the hotrolled product. when the hotrolled product is cooled, then that is rerolled in the room temperature. it is known as cold rolled product. it is used to do to get more exact or perfect dimensions and to make the surface quality better. there are such cold rolled products.
