Abstract：The failure of the mechanical system of the tundish roaster in the continuous casting workshop of a steel plant is the damage of the burner sealing device and the fire shield. Common failures of the media system manifest as damage to the built-in control valve. Common faults in electrical systems are electrical component failure, and blower motor failure. In order to reduce the impact of equipment failure on continuous production, the common causes of roasters are analyzed, and the roasters are adapted to the actual working conditions to improve the service life of the burner sealing device and the fire cover and shorten the service life. The replacement time of the media pipeline valve reduces the failure rate of electrical components and solves the problem of blower motor failure. Through renovation, the daily maintenance cost of the equipment is reduced and the stability of the equipment is improved.
