本文研究了液芯钢锭轧制时三维空间中的金属流动,还计算了钢锭的传搁时间、加热时间、液芯率以及热含量等.试验表明,液芯率≤6%的钢锭可以进行正常轧制.当FX8.5t钢锭的传搁时间及加热时间之和为120min左右时即可得到≤6%的液芯率.目前,这一研究成果已被用于攀枝花钢铁公司的初轧生产,并取得了很好的经济效果. In this paper, the flow of metal in the three-dimensional space of the liquid steel ingot rolling is studied, and the transfer time, heating time, liquid-core rate and heat content of the steel ingot are also calculated.The tests show that the steel ingot with the liquid- Rolling.When FX8.5t steel ingot put aside time and heating time and the sum of 120min or so can get the liquid rate of 6% .The present research results have been used for the initial rolling production of Panzhihua Iron and Steel Company, And achieved good economic results.
