提高冲天炉铁水温度,是改善铸件内在质量,满足我厂内燃机新产品“薄壁高强”铸铁件试制与生产需要的关键条件之一,而使用铸造焦是最根本的有效途径。我厂在不改变焦此(1:12.5)、保持原有生产及工艺不变的情况下,进行了使用铸造焦熔炼的生产试验,并取得了明显的效果。 To improve the temperature of hot metal in the cupola is one of the key conditions to improve the internal quality of castings and meet the trial production and production requirements of the new product “Thin Wall High Strength” cast iron of our plant. The use of foundry coke is the most fundamental and effective way. I plant without changing the coke (1: 12.5), to maintain the original production and process unchanged under the circumstances, the use of foundry coke production test, and achieved significant results.
