Latest Patents

The provided information lists 1 patent for Chunjuan Shao: “Plastic Mold Steel Plate and Method for Producing Same.” The invention describes heating a billet with a soaking-section temperature of 1210–1250°C, then rolling it into a steel plate. The initial rolling temperature is 1060–1140°C, and the final rolling temperature is 980–1050°C.

After rolling, the plate is air-cooled on a cooling bed to 200°C or lower and then normalized at a temperature of A+60°C to A+90°C. It is subsequently air-cooled to B−50°C to B−20°C. The plate is then cross-stacked with ferritic-pearlitic steel plate at 450–550°C, allowing it to self-temper until it reaches B−50°C to B−20°C, before being unstacked and air-cooled.
