rollable temperature in a reheating furnace. This is the starting point of the hot rolling mill practice. Reheating Furnace x Cold stocks are heated to make them soft and thus suitable for rolling. x Furnace has three parts: walls, roof and hearth. Furnace is lined with several layers of refractory bricks. It is insulated by glass wool.
Cold Rolled Product: Cold rolled product is made from the hot-rolled product. When the hot-rolled product is cooled, then that is re-rolled 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.
• As-rolled pearlitic steels, which may include carbon-manganese steels but which may also have small additions of other alloying elements to enhance strength, toughness, formability, and weldability • Acicular ferrite (low-carbon bainite) steels,which are low-carbon (less than 0.05% C) steels with an excellent combination of high yield

A hot rolled bar comes out of the mill with a rough, abrasive, discolored, and dirty surface. This is because the steel at the mill is finished at temperatures upwards of 1600° F to 2200° F, and at these high temperatures an iron scale forms on the surface of the bars.

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. 5.14.Perhaps the most important parameters in the production of a strong {111} recrystallization texture are the annealing temperature and the time of holding [35].

the Flex Mill. It consists of a thin-slab caster, a tunnel furnace, and a rolling mill with six stands and one downcoiler. Caster The cast slab thicknesses range from 55 to 85 mm (2.17 to 3.35 inches) and allow the mill to "flex" between heavy and light gauges, as well as meet reduction ratios required in producing demanding steel grades.
Mill ECL Cold Rolled Coil BAF TM RC 5) Temper Mill The annealed coils are processed in the temper mill. This process applies light pressure to the strip to improve its flatness and to prevent the occurrence of stretcher-strain during forming and deep drawing.
Innovative technologies. One of the most outstanding products in the ANDRITZ Metals portfolio is its patented S6-high rolling mill.

These steels are usually supplied in the hot rolled condition although markets are developing for thinner, cold rolled steels. The increased strength in these materials is usually obtained by grain refinement and precipitation by means of micro-alloying with Cb, V or Ti and by controlled mill processing.

Looper equipment. Loopers are material accumulating devices used for transferring, winding, and unwinding rolled steel. In surface treatment lines such as CAL and CGL, when the seams between coils on the inlet side are welded or the coiled steel on the outlet side is cut for continuous surface processing, or when flow is intermittent, the looper tower carriage is raised and accumulated steel ...
Cold rolling takes the hot rolled product and processes it further. After hot rolling, the steel is cooled to room temperature, then passed through cold rollers at a temperature lower than its recrystallisation temperature. This rolling process is called annealing and relieves stress and leads to a higher yield strength and greater hardness.
Hot and cold metalworking between two or more rolls has been in existence since long before the industrial revolution. As a matter of fact, Leonardo da Vinci was credited for the metalworking mill prior to his death in 1519. When most people think of a rolling mill, they visualize sizable machinery in ferrous (iron, carbon steel
