Hot rolled plate

Manufacturing hot rolled plates involves a continuous process, in which the steel slabs are rolled continuously at a high temperature --- usually over 1,000 degrees Fahrenheit. Continuous monitoring of the temperature is required at this stage to ensure that it is maintained at the recrystallization temperature. If at any stage, the temperature goes below the recrystallization temperature, then raw material has to be reheated before further rolling process can be continued. The steel slabs or sheets are passed through the roller and then cut into required sizes and after which they are cooled off.

Often, these hot rolled materials possess oxides or other contaminants. These can be removed using a special treatment called pickling, which involves using an acidic solution, that lends a smooth, oxide free surface.

Such hot rolled plates usually have less directionality, and at times, may have residual stress and hence these can be used in construction works where materials with defined dimension and shapes are not mandatory.
