FIELD: machine building.
SUBSTANCE: invention relates to methods of making wheel rim, disc and steel wheel and steel wheel, which is made using these methods. Rim of wheel/disc wheel is heated in furnace for heating and heated workpiece of wheel/disc rim is moved to hot press. Temperature of the wheel rim/disc rim is maintained above the required temperature when the heated workpiece of the wheel/disc rim is moved to the hot press. Then the rim of the wheel/disc is shaped in a hot press. Formed rim of wheel (102) and formed disc (104) are connected to produce steel wheel (100).
EFFECT: technical result consists in providing a steel wheel with weight less than weight of a steel wheel made using a conventional method, ensuring dimensional stability and wear resistance of the article.
