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.

A cooling bed is part of a rolling mill, at the end of the rolling mill that supports and permits the hot rolled products from the hot mill to cool hot rolled and cast steel products. A walking beam cooling bed is the most common type of cooling bed. What one wants to happen is for all the temperature of the bar to all cool at the same time.
Hot rolling begins with heating the billet or blooms to a high temperature of around 1100 degrees Celsius. The temperature is of particular importance. Hot rolling and hot extruding drawing involves working above the recrystallization point of the steel. The mill passes the heated material through a variable number of stands.
Walking beam reheating furnace is widely used in mechanized hearth furnace, and is the main type of furnace to replace pusher furnace.. The bottom of the walking beam reheating furnace is basically composed of movable part and fixed part. According to its different structure, there are walking beam type, walking bottom type, walking beam type and bottom combined heating furnace.
Hot rolling is the most commonly used and well-known technology for producing carbon steel and smaller stainess steel profiles. Depending on the alloy, desired shape, mechanical properties, and surface aspect, hot rolling can be the most suitable and cost effective production method. Cost Savings and Sizes of Hot Rolled Profiles

Bar rolling mill cooling bed almost all walking beam cooling bed. With the increase of annual output requirements of rolling mills, the structure of step-type walking beam cooling beds is gradually improved to adapt to higher annual output and higher rolling speed.
Contact-free measurement of the temperature in steel and rolling mills and in metal working. The monitoring of temperature with contact-free yet precise measurement of the object is gaining tremendous importance in the steel and iron industry.
According to the type of rolling mill: (1) Flat roll. That is, the roll body of plate and strip mill is cylindrical. Generally, the roll of hot rolling plate rolling mill is made into micro concave shape, which can obtain better shape when heated; the roll of cold rolling plate rolling mill is made of micro convex shape, and the roll will bend during rolling to obtain good shape.
Cold Strip Mill Cold rolled strip steel and sheet steel generally have a thickness of 0.1 - 3 mm and a width of 100 - 2000 mm; All of them take hot rolled strip steel or steel plate as raw materials and are rolled into products by cold rolling mill at normal temperature.
Apr 13, 2013· Reheating furnaces are used in hot rolling mills to heat the steel stock (Billets, blooms or slabs) to the rolling temperatures of around 1200 deg C which is suitable for plastic deformation of steel and hence for rolling in the 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.
