1.对冲天炉熔炼工作的要求Ⅰ铁水温度要高:高强度铸铁、球墨铸铁要求在1400°以上;Ⅱ铁水的化学成份能够控制,合符要求,便于生产各种牌号的铸铁; Ⅲ燃料、电力和熔制的耗赞少,元素烧损少;Ⅳ炉子的单位生产率要高,即每平方米炉膛截面积每小时熔化的铁水量要多;Ⅴ炉子结构简单,操作方便;炉子连续工作的时间要长。一般情况下,观察一个炉子的工作好坏,首先是看它熔化出的铁水温度有多少高?焦铁比多少?因为这两项与铸件的质量、废品多少有直接关系,但是要全面评价一个冲天炉,必须按以上五项全面考虑,通盘要
1, the requirements of the cupola melting work Ⅰ hot metal temperature is high: high-strength cast iron, ductile iron requirements in 1400 ° or more; Ⅱ molten iron chemical composition can be controlled, in line with the requirements for the production of various grades of cast iron; Ⅲ fuel, Power consumption and melting of less praise, less burning element; Ⅳ furnace unit production rate is high, that is, per square meter of the furnace cross-sectional area of molten iron per hour to be more; Ⅴ furnace structure is simple, easy to operate; furnace continuous operation Time is longer. Under normal circumstances, the observation of a furnace work is good or bad, the first is to see how much it melts out of the hot metal temperature? Coke iron ratio? Because these two and castings quality, how much scrap is directly related to, but to fully evaluate a Cupola, must be more comprehensive consideration of the above five, all-round to
