| description | The invention relates to a lifting appliance for rapidly replacing a continuous casting dummy bar head as well as a lifting plate surface nitriding treatment process. The lifting plate surface nitriding treatment process comprises the following steps that (1) a lifting plate of the lifting appliance is put into a nitriding furnace, the temperature is increased to 350 DEG C from the room temperature, and the temperature increasing process is completed within 4-5 hours; (2), the temperature of 350 DEG C is kept for 4-5 hours; (3), the temperature is increased to 500 DEG C from 350 DEG C, and thetemperature increasing process is completed within 2-3 hours; (4), the temperature is kept at 500 DEG C for 25-30 hours; and (5), the temperature is decreased to room temperature from 500 DEG C, andthe temperature decreasing process is completed within 7-8 hours. The lifting appliance can be widely applied to production procedures in continuous steel casting, the production labor amount is reduced, and the operation effi |
