Error. 1. The purpose of drying the furnace is to remove the free water and crystalline water from the lining, so as to prevent excessive expansion of water when the furnace temperature rises rapidly at startup, which could cause the furnace body to crack, bulge, deform, or even have its walls collapse. This would affect the strength and service life of the heating furnace’s walls. 2. Further familiarize oneself with the performance of the instruments in the furnace area, and verify whether they meet the production requirements. 3. Evaluate the performance of various furnace components under hot conditions. 4. Conduct on-the-job training to improve operational skills.
