| Abstract: | The present paper carefully investigates and analyzes the causes to the longitudinal edge crack of slab and finds out that the primary cause is inappropriate distribution of the cooling water slits of the mould copper plates. By optimization of the cooling water slits of the mould copper plates and perfection of part of the processing parameters the longitudinal edge cracks have been effectively eliminated. |
