炉喉钢砖是安装在高炉炉喉部位的重要零部件,不但要承受400℃～500℃的高温,而且还要承受炼铁原料的冲击磨损,根据高炉的特点,确定较适宜铸造工艺方案,保证钢砖的尺寸精度和材质性能,实现其寿命与高炉寿命同步,在生产过程中,针对薄壁复杂结构的铸件特点,采用合理的浇冒口系统,实现同时凝固原则,解决铸件的变形、裂纹问题,铸件的工艺出品率提高了20%,满足了高炉使用性能要求。
The throat steel brick is an important part installed in the throat of the blast furnace. It not only has to withstand the high temperature of 400 ℃ ~ 500 ℃, but also bear the impact of wear and tear of raw materials, according to the characteristics of the blast furnace to determine more suitable casting process, Ensure the dimensional accuracy and material properties of the steel brick and realize the synchronization of its life with the life of the blast furnace. In the production process, aiming at the characteristics of the thin-walled and complex structure castings, the reasonable pouring and riser system is adopted to realize the simultaneous solidification principle and solve the deformation, Crack problems, casting process technology increased by 20%, to meet the performance requirements of the blast furnace.
