To take away the refining part of the steel making cycle off an electric arc furnace, which is discussed elsewhere, is an excellent start.

把炼钢周期中的精炼阶段从电弧炉中移走（这个问题将在别处加以讨论），是一个良好的开端。

The first electric arc furnace was installed. The arc furnace recycled locally collected scrap steel by melting and refining, then continuously casting the molten steel into billets.

建成自己的第一座电弧熔炉，将本地收购的废铁回收再造，重新熔化、精炼，然后连续铸造成钢鉟。

By means of crushing and conditioning the size ratio, fettle material and mud powder to plug tap-hole for electric refining furnace use were developed.

通过加工破碎，调整粒度及配比等工艺参数，研制开发出铁合金精炼炉补炉料及堵眼粉。
