我们从苏联杂志上看到了“利用冲天炉的炉渣作防止粘砂的材料”一文后,就开始进行了用冲天炉的炉渣代替石墨作涂料的试验。现在把试验过程中取得的初步的经验介绍于下: 一、炉渣的处理和涂料的制备: 选择颜色正常的炉渣,去掉杂质,放在碾砂机中轧碎,然后用筛子过筛,用100目以下的粉末作配方的原料。炉渣的化学成分如下:二氧化硅(SiO_2)53.3％;氧化鉄(FeO)4.54％;氧化锰(MnO)5.05％;氧化钙(CaO)28.4％;氧化镁(MgO)3％。
After we read the article from Soviet magazines on the use of cupola furnace slag as a material to prevent sticking, we started the experiment of using cupola furnace slag instead of graphite as a coating material. Now the initial experience gained during the experiment introduced in the following: First, the treatment of slag and paint preparation: Select the color of normal slag, remove impurities, crushed on a sand mill, and then sieved with a sieve, with 100 The following powder for the formulation of raw materials. The chemical composition of the slag is as follows: 53.3% of silicon dioxide (SiO 2); 4.54% of molybdenum oxide (FeO); 5.05% of manganese oxide (MnO); 28.4% of calcium oxide (CaO); and 3% of magnesium oxide (MgO).
