Latest Patents

Yang’s patent, “Plastic Mold Steel Plate and Method for Producing Same,” describes a production process designed to control the steel plate’s temperature through multiple manufacturing stages. The method heats a billet in a soaking section at 1210–1250°C, then rolls it into a steel plate with an initial rolling temperature of 1060–1140°C and a final rolling temperature of 980–1050°C.

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