A method and device for controlling the rotational speed of a hot blank discharging motor of a heating furnace in a rolling workshop

Abstract

The invention discloses a method and a device for controlling the rotational speed of a hot blank discharging motor of a heating furnace in a rolling workshop. The real-time temperature value m of the temperature sensor and the running speed v of the discharging roller table are obtained; wherein, the temperature sensor is installed on the hot blank discharging roller table of the heating furnace. , and the distance d from the opening of the heating furnace is greater than the length d of the billet 钢坯 According to the real-time temperature value m and the running speed v, the rotating speed of the discharging motor is determined; in the present invention, the real-time temperature of the temperature sensor installed on the hot blank discharging roller table of the heating furnace can be obtained, and the current running speed of the discharging roller table can be judged. The running state of the billet on the tapping roller table, and according to the current running status of the billet, the speed of the tapping motor of the rolling table is adjusted, which improves the tapping efficiency of the heating furnace and avoids safety accidents caused by subjective judgments.

Description

technical field [0001] The invention belongs to the technical field of fine control of steel rolling equipment, and in particular relates to a method and a device for controlling the rotational speed of a motor for hot blank discharge of a heating furnace in a steel rolling workshop. Background technique [0002] The steel rolling workshop is a workshop that rolls the billets into finished steel products. In this workshop, the billets first enter the heating furnace for heating. After heating to a predetermined temperature, the heated billets are transported to the steel inlet of the rolling mill through the roller table. In this process, the running speed of the roller table is affected by the speed of the hot blank discharge motor. When the motor speed is too fast, the hot billet may have an impact on the steel inlet of the rolling mill, and even the last billet may not fully enter the rolling mill, which is prone to accidents. When the motor speed is too slow, it is poss...
