我们采用空心微珠保温冒口套生产铸钢轧辊,比原工艺冒口直径减少20毫米,高度降低20%,冒口体积减少16%左右,工艺出品率提高10%左右.同时省去捣冒口操作,改善工人劳动条件,基本消除缩孔缺陷,而且大大减少了铸钢轧辊的缩松缺陷,提高了轧辊致密度,降低了废品率.因此,采用空心微珠保温冒口套是一项节约钢水、减少能耗、降低成本的有效措施之一. We use Hollow Bead Insulating Sleeve to produce cast steel rolls, 20mm less diameter than the original riser, 20% reduction in height, about 16% reduction in riser volume, and 10% increase in process yield. Mouth operation, to improve working conditions of workers, the basic elimination of shrinkage defects, but also greatly reduces the shrinkage of cast steel roll defects and improve the roll density, reducing the rejection rate.Therefore, the use of hollow micro-bead insulation riser sleeve is a Saving steel, reduce energy consumption, reduce costs, one of the effective measures.
