In order to improve the service life of refractory brick and reduce the consumption of refractory brick, need to conduct reasonable smelting operation system. Smelting operation factors are many, and mutual restraint, should mainly from the following aspects:
1. To control the silicon content and other bulk material SiO2 content, reduce the erosion rate of fused magnesia brick.
2. To control the temperature.
3. To improve the quality of raw materials.
4. To control the right oxygen supply system and a reasonable oxygen lance structure to reduce splashing and shorten the smelting operating time.
5. To control the end of blowing.
6. To strengthen the production management to prevent splashing when blowing.
