What is the difference between hot rolled steel and controlled rolled steel?Can two kinds of steel plates be used interchangeably?
The ideal special performance is obtained by controlling the amount of deformation and the temperature of deformation.With higher added value and higher prices.Interchangeable, but not a good choice!
Thermal-mechanical rolling is commonly known as controlled rolling, that is, in the process of rolling to control the temperature of the metal, so as to obtain some precious properties of the metal, such as refined grain structure, good plasticity and relatively high mechanical strength and so on.Is a relatively common rolling method.Both cold and hot rolling methods are available.

At the same time, due to the small width to thickness ratio of steel plate, the size accuracy requirements are relatively low, not easy to appear plate shape problems, mainly to control the crown.For microstructure requirements, generally through the control rolling control cold to achieve, that is, to control the finishing rolling temperature, rolling temperature and curling temperature to control the strip microstructure and mechanical properties.
