采用炭黑浇注,钢锭模不涂油,显著地提高了钢的质量,简化了操作工艺,改善了劳动条件,并降低了成本。我厂所生产的镇静钢种类很多,使用模型亦不相同,最初生产5.6吨的钢锭,使用的模型较小,采取了“高温快注”,即所谓“亮圈浇注”的方法。以后,由于钢锭加大,浇注方法亦随之改变,当生产8.3和8.8吨钢锭时,在“亮圈浇注”的基础上,又采用模内加木框。由于注速较快,
The use of carbon black casting, ingot mold is not oiled, significantly improving the quality of steel, simplifying the operation process, improve working conditions, and reduce costs. I plant a lot of production of static steel, the use of the model is not the same, the initial production of 5.6 tons of ingot, the use of smaller models, adopted the “high temperature fast injection”, the so-called “bright circle pouring” approach. Later, due to the increase of ingot, pouring method also changed, when the production of 8.3 and 8.8 tons of ingot, the “bright circle pouring” on the basis of the use of mold plus wood frame. Due to faster speed injection,
