摘　　要：Based on introducing equipments and technology conditions of continuous casting plant of the 4th sub-factory of general steelmaking factory of WISCO, the operation of tundish casting auto-start, control of withdrawal straightening device drive start and control of mould level are analyzed, the critical effect of liquid level control is emphasized in this part. Through comprehensive industrial scale experiments, several relevant problems were solved in application process, which promoted the rate of auto-casting of the factory to beyond 98 percent stably from 39 at the beginning.Based on introducing equipments and technology conditions of continuous casting plant of the 4th sub-factory of general steelmaking factory of WISCO, the operation of tundish casting auto-start, control of withdrawal straightening device drive start and control of mould level are analyzed, the critical effect of liquid level control is emphasized in this part.
