Embodiment 1
[0022] A blowing air cooling process is added between the slag scraping and edge trimming process, and the blowing wind pressure is 0.5 MPa, and the content of the invention is implemented. The production process of high-strength wheel steel with a tensile strength of 590MPa and a thickness of 5mm is as follows: blanking→rolling→flattening→welding→slag scraping→air cooling→edge trimming→flaring→primary rolling→secondary rolling →Three roll forming→finishing→air tightness inspection→press fitting→combined welding→electrophoresis treatment. In the welding process, the welding allowance is 42mm, the welding voltage is 10.8V, the upsetting amount is 6.5mm, the preheating power-on time is 10 times×0.1s, the pulse period is 0.5s, the flashing time is 12s, and the upsetting charging time is 0.3s; In the cooling process, the initial temperature of the steel wheel weld area is 600°C when the compressed air is sprayed, and the steel wheel weld area is cooled to room temperature at a coo...
