冲天炉

冲天炉是高高的圆柱炉,用于融化铁和铁合金铸造行动。金属和亚铁合金,可乐和石灰石的交替层从顶部送入炉子。电视剧的示意图如图所示。整个冲天炉的图显示了炉子的圆柱轴,衬有难治性和可乐和金属废料的交替层。熔融金属从冲天炉底部的喷口流出。

电杯的描述

  • The cupola consists of a vertical cylindrical steel sheet and lined inside with acid refractory bricks. The lining is generally thicker in the lower portion of the cupola as the temperature are higher than in upper portion
  • 有一个充电门,可乐,钢铁,钢废料和通量充电
  • 爆炸被Theeres吹来
  • 这些Tuyeres在冲天炉周围的一排或多个行中排列
  • 从底部(燃烧区)上升的热气预热区域中的铁
  • 滚杯带有下滴底门,通过该碎屑,由可乐,炉渣等组成的碎屑可以在熔体的末端排出
  • 提供了一个炉渣孔,以从熔体上去除炉渣
  • 通过水龙头孔熔融金属倒入钢包
  • At the top conical cap called the spark arrest is provided to prevent the spark emerging to outside.

手术:-

首先,底部的掉落门关闭。沙床朝向锥孔的坡度撞了。在沙床上方准备合适高度的可乐床,并通过水龙头孔点燃。正确点火后,替代电荷,通量和可乐通过电荷门喂食。然后使电荷浸泡在热量中,并打开空气爆炸。在5至10分钟内,通过水龙头孔收集熔融金属。当收集足够的金属在冲天炉的井中时,将炉渣从炉渣孔中排出。然后将熔融金属收集到钢包中,并以最小的时间损失运输到模具中。
助熔剂添加负责去除氧化物s and other impurities present in the metal. The flux commonly used is lime stone (CaCO3) in a proportion of 2 to 4% of the metal charge. Others fluxes used are dolomite, sodium carbonate, calcium carbide. Flux reacts with oxides to form compounds having low melting point and lighter so that it will float on the metal pool.

收费计算: -

碳:-
当电荷通过可乐床时,金属会根据温度和金属与可乐接触的时间捡起一些碳。它的碳含量为0.15%。
硅:-
它在冲天炉中被氧化,将损失10%的硅。它可能高达30%。为了增加硅含量,将铁西硅添加到金属中。
锰:-
在熔化过程中损失了15%至20%的锰。锰的含量可以通过添加铁龙烷剂来增加。
硫-
硫将在0.03至0.05%的范围内取货。
