FIELD: crushing equipment.
SUBSTANCE: method consists in making castings from high-manganese steel, hardening and soaking in a furnace. The plates are made in the form of separate sections, the section blank is heated for 2.1 to 2.3 hours to a temperature of 1100 to 1200°C and soaked in a furnace at a temperature of 1100 to 1200°C for 2.7 to 2.9 hours. After soaking, the section blank is forged for 25 to 35 seconds in a closed die of a stamping press with a force of 200MN, after which the section blank is quenched in water.
EFFECT: improved wear resistance of jaw crusher plates.
