摘要
随着制造行业发展和环保要求的加强,锻造工艺向着节能化、精密化、轻量化、数字化、智能化等方向发展。为了满足锻造工艺的发展要求,对特殊钢棒材加工工艺进行了系统地研究,从钢的均匀性控制、纯净度控制、车削性控制、表面质量控制、热轧态组织控制、表面脱碳控制、氧化铁皮控制、尺寸精度控制及平直度控制方面制定相应的工艺措施,改善了特殊钢棒材的组织均匀性、尺寸精度、脱碳层深度、氧化铁皮厚度等关键性质量指标。
With the development of manufacturing industry and the enhancement of environmental protection requirements,forging process is developing towards energy saving,precision,lightweight,digitalization and intellectualization.In order to meet the development requirements of the forging process,the processing technology of special steel bar was systematically studied including.From the aspects of homogeneity control,purity control,turning control,surface quality control,hot rolling structure control,surface decarburization control,scale control,size accuracy control and straightness control,the corresponding technological measures are formulated to improve the key quality indexes of special steel bars,such as structure uniformity,size accuracy,decarburization depth and scale thickness.
