- 摘要:
- 国内铸造厂使用的小型铁液包通常使用单层耐火材料包衬,铁液在这种铁液包中温度下降很快。为了减缓铁液在浇注过程中的温降,设计了一种新的小型铁液包包衬结构,使用3种导热系数耐火材料制作包衬。结果表明,3层耐火材料包衬设计,减缓了铁液在浇注过程中的温降,对浇铸温度提高和节能减排效果显著。在相同工况下,3层包衬的铁液最终浇铸温度比单层包衬高29℃。
The small molten iron ladles used in domestic foundries are usually lined with single-layer refractory material. In order to slow down the temperature drop of molten iron during the pouring process, a new small type of lining structure of molten iron ladle was designed. The lining was made of three refractory materials with thermal conductivity. The results show that the three-layer refractory lining design slows down the temperature drop of molten iron in the pouring process,and has significant effect on the improvement of casting temperature and energy saving and emission reduction. Under the same working condition, the final casting temperature of molten iron in the three-layer lining is 29 ℃ higher than that in the single-layer lining.
