Aiming at the phenomenon of low steel flow rate of copper tube in billet caster mold, how to improve the service life of copper tube is analyzed from two aspects of mold system assembly and process factors? 1. Optimize the material, size, taper and water gap of mould copper tube; 2. Improve the quality, pressure and flow of cooling water; 3. Reduce the superheat of molten steel in tundish; 4. Reduce the pulling speed appropriately. |
