武钢第一炼钢厂拥有6座500吨固定式顶吹氧大型平炉,炉后配置双罐双流出钢方式。其冶炼品种为普碳钢、优结钢、低合金钢、专用钢板、半镇静钢和重轨钢等。每炉钢良锭460～480吨,由于成分出格所造成的号外损失一罐或一炉钢达10～25万元。因此,钢锭化学成分(熔炼分析成分)的命中极为重要。一、钢锭化学成分出格现状一炼钢生产的钢锭多为普碳钢及低合金钢,当钢锭表面质量符合要求时,钢锭判定仅以冶炼成分(C、Si、Mn、P、S)为依据传送至初轧厂。图1为1985年～1987年钢锭化学成分出
Wuhan Iron and Steel No. 1 Steel Works has six 500-ton fixed-top oxygen blowing furnace, after the furnace configuration double-tank dual-flow out of steel way. The smelting varieties of carbon steel, excellent knot steel, low alloy steel, special steel, semi-killed steel and heavy rail steel. Steel ingot per furnace 460 to 480 tons, due to the composition caused by the exception of the number of one or a loss of a can of steel up to 10 to 25 million. Therefore, the chemical composition of steel ingot (melting analysis component) hits is extremely important. First, the actual chemical composition of the ingot A steel ingot produced mostly steel carbon steel and low alloy steel, when the ingot surface quality to meet the requirements, the ingot is determined to only smelting composition (C, Si, Mn, P, S) Send to the early rolling mill. Figure 1 shows the chemical composition of ingot from 1985 to 1987
