原料:耐火炭砖制造,系以焦炭和焦油为原料。焦炭须灰分低,强力大,化合性不高。上等铸造焦却合于这些条件,但煤气焦(强力低),高炉焦(可燃性高)均不适用。焦炭,在制作前,须十分干燥,并压碎约至1毫米的颗粒,通过颚氏粗碎机后,如有必要,使再通过碾盘、管磨或球磨。焦油,采用炼钢厂不含水分的焦油,此系沥青溶于泥煤焦油的高沸点成分的溶液,其中常加入少量(10%)能熔于高温的硬石油沥青。按苏联报告介绍,将焦油、蒽油和沥青的混合物中,加少量萘使用。
Raw materials: fire-resistant brick manufacturing, Department of coke and tar as raw materials. Coke ash to be low, strong, chemical compound is not high. Co-foundry coke meets these conditions, but neither gas coke (low strength) nor blast furnace coke (high flammability) applies. Coke, which must be very dry before crushing and crushing granules up to about 1 mm in diameter, pass through a jaw crusher and, if necessary, pass through a pan, tube mill or ball mill. Tar, using steel-making plant moisture-free tar, is a solution of pitch dissolved in the high-boiling components of peat tar, often containing small amounts (10%) of hard petroleum bitumen that melt at high temperatures. According to the report of the Soviet Union, the tar, anthracene oil and asphalt mixture, add a small amount of naphthalene.
