Steel Forming Process 1 – Hot Rolled Steel. Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel's recrystallization temperature. When steel material is above the recrystallization temperature, it can be shaped and formed easily, and the ...

The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.

Endless Hot Strip Rolling Process . In conventional hot strip production, slabs of thickness of about 250mm are heated in a furnace and are reduced to 30 to 60mm in thickness after passing through the roughing mill, and then further reducing it to within a range of 0.8 to 25.4mm by rolling in the finishing mill.

Sep 11, 2014 · Hot Rolled Steel. Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel's recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes.
Direct production of hot rolled strip by connecting the thin slab casting process with the hot rolling process was introduced around 1990.

1. Hot rolling and rolling defects: 1.1 Front and back tensions: We have seen that the rolling load is dependent on roll diameter, higher the roll dia, higher the roll force. Similarly, smaller reductions requires lower roll force. In order to reduce the roll force, we can reduce roll diameter, or reducing the friction.

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.

HOT-ROLLED STEEL. Hot-rolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature; a heat that typically exceeds 1000° F. When steel is heated past its recrystallization point, it becomes more malleable and can be properly formed and shaped.

In rolling mills, intermediate steel products are given their final shape and dimension in a series of shaping and finishing operations. Most of the slabs are heated in reheating furnaces and rolled into final shape in hot– or cold–rolling or finishing mills. While some products (e.g. reinforcement bars, steel plates) only require hot-rolling, some others may require both hot– and cold ...

We can also conclude that higher coefficient of friction can allow larger thickness of the strip to be drawn into the roll throa t. Longitudinal grooves are made on the roll surface in order to increase friction. This enables the breakdown of large thickness ingots during hot rolling.
