采用不对称异径三辊轧机进行热连轧薄带钢生产试验研究，结果表明：（１）不对称轧制时由于金属与辊面接触面积减小和单位压力的下降而使轧制压力大幅度降低（４８％～６２％），显著提高了轧制效率；（２）所轧产品最小厚度由原二辊同径轧制的２．７５ｍｍ．减小到１．５ｍｍ，产品精度质量也得到提高，（３）用这种热轧薄带钢代替冷轧带钢制造轻型薄壁焊管，显著降低生产成本，提高经济效益． The results show that: (1) When the contact area of ​​metal and roller surface is decreased and the unit pressure is decreased, the rolling pressure is large due to the asymmetric reduction three-roll mill. (48% ~ 62%), significantly improve the rolling efficiency; (2) the minimum thickness of the product rolling by the original two roll diameter 2.75mm. Reduced to 1.5mm, product quality has also been improved precision, (3) the use of such hot-rolled thin strip instead of cold-rolled strip steel thin-walled tube, significantly reducing production costs and improve economic efficiency.
