The invention relates to a method for producing steel wheel rim with inner tyre and without welding seam, wherein it comprises: feeding the material of casting steel tube, heating, rolling, rolling, rounding, rotationally compressing, rotating the rim, machining two ends and punching the valve hole; slicing the casting blank steel tube into two tubes; heating to casting temperature; rolling it into middle blank; using rolling machine to roll one end into one lock annular grove; using rounding machine to round; using rotational compressor to rotationally compress its outer wall, to make the thickness of the bottom of rim and the tyre base meet the demand; making the rim; then machining two ends and punching the valve hole. The invention has better quality and safe operation, with lower cost. And it uses thermal rolling technique, the casting organism is changed into smelting organism; and it uses cool rotational compression to improve the accuracy and strength of rim. |
