Abstract
Some embodiments of the present disclosure provide manufacturing methods for a wheel rim, a spoke and a steel wheel and a steel wheel formed by the methods. The methods includes that: a wheel rim/a spoke blank is heated in a heating furnace, and the heated wheel rim/the heated spoke blank is transferred onto a hot press. A temperature of the wheel rim/the spoke blank being required to be kept above a required temperature in a process of transferring the heated wheel rim/the heated spoke blank to the hot press. Then the wheel rim/the spoke blank is formed in the hot press. A formed wheel rim and a formed spoke are connected to product a steel wheel.
