冲天炉辅加焦粉新技术,是铸造行业提高铸件质量、节约能源的一项有效措施。我厂是一个专业铸造厂,生产特点是单件小批生产,产品品种繁多,几何形状复杂,铸铁牌号有 HT20-40和球墨铸铁,其中球铁占年产量的一半。特别是外贸铸件,轻的0.3公斤,重的不超过3公斤,铸件壁厚只有1.5～3毫米,因此对冲天炉要求出铁温度高,元素烧损少,炉况稳定。原两台5吨/时“倒、大、双”冲天炉已不能满足生产需要。为此我们将一号炉 Cupola auxiliary coke powder new technology is casting industry to improve the quality of castings, energy conservation is an effective measure. Our factory is a professional foundry, the production is characterized by a single small batch production, product variety, complex geometry, cast iron grades HT20-40 and ductile iron, ductile iron which accounts for half of the annual output. In particular, foreign trade castings, light 0.3 kg, heavy no more than 3 kg, castings wall thickness of only 1.5 to 3 mm, so the requirements of the cupola tapping temperature, the element burning less stable condition. The original two 5 tons / hour “down, big, double” Cupola can not meet the production needs. To this end we will be a furnace
