为了简化复杂的保温冒口计算,减少工作量和节省时间,充分利用普通冒口的合理工艺参数,我们将有关保温冒口的计算公式绘制成曲线图,使复杂的数学式变得直观、明了,并且使用简便,数据可靠。一依据 1.保温冒口由于使用保温套和(发热)覆盖剂,延长了冒口的补缩时间,提高了补缩效率。实际生产证明,使用保温冒口后,其体积可以比普通冒口缩小一半以上。
In order to simplify the calculation of complex thermal insulation risers, reduce the workload and save time and make full use of the reasonable technological parameters of ordinary riser, we draw the calculation formula of thermal insulation riser into a graph, make the complicated mathematical formulas become intuitive and clear , And easy to use, reliable data. A basis 1. Insulation riser due to the use of insulation cover and (fever) covering agent, extending the feeder riser time and improve the efficiency of feeding. The actual production certificate, the use of thermal riser, its volume can be reduced more than half of the average riser.
