防止Ｈ型钢腹板偏心的轧制技术日本住友金属工业公司在Ｈ型钢生产中采用以万能轧机变更Ｈ型钢腹板高度的技术，但产生了腹板偏心和翼缘宽度变动的问题。最近，该公司钢铁技术研究所用模型轧机进行了试验研究。试验方法是边用万能机上的带孔型的水平轧辊约束翼缘的端部，边... Rolling Technology to Prevent Eccentricity of H-Beam Webs Sumitomo Metal Industries, Japan, adopted a technique of changing the web height of H-beams with a universal rolling mill in the production of H-beams, but posed the problem of web eccentricity and flange width variation. Recently, the company’s steel technology research institute used a model rolling mill for experimental research. Test method is to use a universal machine with a hole-type horizontal roll restraining the edge of the flange, ...
