Hot Rolled Steel Sheets Manufacturing Process

Hot rolled sheet and plate mechanical properties hot rolled sheet and plate maintains many unique properties that separate it from other processes such as cold rolling.

Hot rolled steel sheets manufacturing process.

Meaning if the temperature is not high enough it can cause defects in the material. Rolling is classified according to the temperature of the metal rolled. In metalworking rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. If the temperature of the metal is above its recrystallization temperature then the process is known as hot rolling.

Hot rolled steel products are divided into two groups. When steel is above the recrystallization temperature it can be shaped and formed easily and the steel can be made in much larger sizes. Sheets hot rolled steel sheets. 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.

Hot rolled steel cold rolled steel forged steel and cast steel. The properties that are exclusive to the hot rolled steel manufacturing process include the following. The amount of heat directly affects the properties of the steel. In its natural state steel is not at all flat.

Steel has the tendency to cling to its original shape and molecular composition. The process in which hot rolled is produced begins with heating slabs of steel to approximately 2 300 degrees fahrenheit. The concept is similar to the rolling of dough. The next step is feeding them to the rolling machinery.

If the temperature of the metal is below its recrystallization temperature the proce. Heated metal in hot rolling process the starting material is usually steel billets or slabs. Jfe steel corporation who holds iso 9001 qs 9000 and iso 14001 certifications produces a wide range of hot rolled steel sheets at the world s strongest and most efficient integrated steel works. The difference between hot rolled.

Slabs produced from a continuous casting system are rolled cooled and coiled into the sizes required by the customers. In fact a hot rolled sheet coil generally reveals some or all symptoms of poor flatness see figure 1. Because it was given a unique configuration when it was rolled cooled and coiled at the steel mill. This post will explain the four different steel forming process.
