用保温车进行钢锭直接轧制的试验表明,沸腾钢Fx10.5t钢锭的模内时间在60min以内装入保温车,不用外部热源直接轧制成钢坯的工艺是可行的,钢坯的质量是合乎标准的。但是,必须严格控制钢锭装车时的热焓和车内均温时间以及开轧时的液芯率。钢锭的直接轧制无燃料消耗,不仅节约大量能源,而且减少烧损,提高了钢锭的成材(坯)率,可获得明显的经济效益。
The test of direct rolling of steel ingot with the insulation car indicated that the in-mold time of the steel boiled steel Fx10.5t was put into the insulation car in less than 60 minutes and the process of direct rolling into billet without external heat source is feasible, the quality of steel billet is in line with the standard of. However, you must strictly control the ingot loading enthalpy and the average temperature inside the car and open the liquid at the time of rolling rate. Direct rolling steel ingot without fuel consumption, not only save a lot of energy, but also reduce burning, increased ingot ingot (billet) rate, access to significant economic benefits.
