What is Hot Rolling? Rolling mill is a metalworking process which divided into two types: hot rolling and cold rolling. Here we will analyze the hot rolling cause we had discussed cold rolling before. In many theory books, which called hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. On ...

Step 1: Heating Heat the steel ingots or billets to a temperature above their recrystallization temperature about 1,700 degrees Fahrenheit or higher. Step 2: Rolling Mill Machine Pass the heated steel through a rolling mill machine. The machine reduces its thickness and shapes it into the desired form.

Rolling in metalworking is a metal forming process that helps to reduce the thickness of metal and make the thickness uniform. The metal stock is passed through one or more pairs of rolls to reduce the material. Rolling is classified according to the temperature of the metal rolled, it is a hot rolling if the temperature of the metal is above ...

Therefore, it is necessary to consider using hot lubrication rolling to reduce roll wear and improve operation rate. From 1935 to 1936, animal oil began to be used to lubricate the roll on the section steel mill in the Soviet Union. In 1968, the hot strip rolling process was first applied to lubricate rolling in the United States.

Abstract. Equations are derived for the normal roll pressure, specific roll load and torque in hot rolling mills, using the condition for plastic deformation in rolling derived by Orowan, together with von Kármán's equation of equilibrium. Although applying strictly to the rolling of ideal plasticrigid materials, these equations may be ...

What Is a Rolling Mill? At its most basic principle, a rolling mill is a machine that reduces the thickness of a metal without sacrificing any of the material meaning material is always displaced and never lost. By design and function, rolling mills do not generate scrap. The process of rolling affects the materials at a metallurgical level ...

Hot Rolling. Cold Rolling. The material to be rolled is above its recrystallization temperature. The material to be rolled is below its recrystallization temperature. The roll radius is larger than used in cold rolling. The roll radius is smaller. Heavy reduction in area of the workpiece can be obtained.

The ingot scalpers are installed upstream of the hot rolling mill. They remove the oxide skin as well as any metallurgical impurities from the surface of the ingots. Scalping the edges reduces the amount of trimming scrap generated in the subsequent hot rolling process and keeps the work rolls clean.
