Power Supply: Before powering on the furnace, inspect the furnace cover, electrodes, mechanical transmission system, water cooling system, and electrical equipment. Address any issues promptly to avoid production halt during smelting. Check for contact between the furnace charge and the furnace door or water cooling system; if contact is detected, it should be eliminated immediately to prevent puncturing upon power-up. Replace electrodes if they are too short before powering on. If the joint position is loose, tighten it first to ensure a successful single well pass, reducing the likelihood of production halts during smelting.
