求翻译：通过配加石英砂，将钢渣碱度由2调整到1.5以下，可以抑制钢渣粉化，但是石英砂配加量需达到15%，实现工业化困难是什么意思？

With addition of quartz sand, slag basicity from 2 to 1.5, can inhibit the slag powder, but with addition of quartz sand to reach 15%, achieve industrialization difficulties

With the quartz sand, will consists of 2 of steelmaking slags alkalinity adjustments to the following, 1.5 of steelmaking slags toner can be suppressed, but with the quartz sand is required to achieve 15 per cent, to achieve industrialization difficulties

Through matches adds the quartz sand, from 2 adjusts the steel slag alkalinity to 1.5 below, may suppress the steel slag pulverization, but the quartz sand matches the increment to have to achieve 15%, the realization industrialization difficulty

By adding quartz sand, slag basicity by 2 to below 1.5, can inhibit the slag powder, but the amount of quartz sand with addition of required 15% to bring about industrialization difficulties
