Product Display
In terms of grades, hot rolled steel coils are usually categorized according to their hardness, strength, toughness and other properties. There are models such as Q195L Q235B Q355B SPHC 510L 700L Q345A Q345E.
In the production process, hot rolled steel coils are rolled by high temperature heating. The temperature of the billet is raised to above 1000°C and then fed into the rolling machinery for rolling. Because the metal is in a state higher than its recrystallization temperature during hot rolling, the internal structure of the steel produced is changed to give it better mechanical properties. In addition, in order to increase the yield of strip products and meet the needs of downstream customers, the hot rolling line will continuously optimize the production process and improve the quality of the coil shape.
In terms of application, hot rolled steel coils are widely used in many fields. For example, in steel fabrication, hot rolled steel coils are mainly used for welding structural pipes and open plates. In addition, compared with cold rolled steel, hot rolled steel can be produced in large quantities, so its market price is relatively low. Overall, hot rolled steel coils are both an important material for industrial production and an important component of many important products and facilities.
