Casting Roll Speed Adjustment Method and Device in Twin Roll Type Sheet Casting Machine

摘要

The present invention is to maintain a constant rotation speed of the casting roll in the new casting method for producing hot coils, which are cast directly from molten steel in a short time, so that the solidification angle of the cast and the heat transfer coefficient of the surface of the casting roll uniform to produce a quality cast The present invention relates to a method and a device for adjusting a casting roll speed in a twin roll type sheet casting device. The rotational speed of the casting roll and the production speed of the cast steel are measured by each measuring sensor and sent to the PLC. Calculate the production speed of the cast steel and send the value to the brush roll controller, the brush roll controller sends the rotation amount of the brush roll to the brush roll motor to increase the rotation speed of the brush roll so that the casting roll maintains the target speed. will be.
