Continuous casting billet on-line weighing and measuring system Continuous Casting Machine
In the production process of efficient continuous casting, due to the wear of mold, the change of molten steel pressure, drawing speed, density, specific gravity and other factors, the same casting flow in different time, casting the same length of continuous casting billet but different weight, and there are great differences. In order to reduce waste, improve the yield of the product and obtain the maximum economic benefit, fixed-weight cutting control is carried out on the basis of infrared fixed-length cutting.
Image acquisition and processing, laser triangulation position calculation.
The purpose of cutting and setting weight
Hot slab intelligent automatic weighing scale cutting system is based on the use of infrared length under the condition of control system, the continuous uninterrupted billet with hydraulic or electric cylinders weighing method called out slab set the actual landed weight and the scale system of closed loop calculation, casting weight implement slab automatically adjust the length by weight, improve the control precision casting weight.
It can adapt to the influence of high temperature radiation, heat conduction and water vapor of weighing machinery at about 800℃
It can eliminate the influence of dynamic lifting of the balance frame on the mechanical stability and repeatability of the sensor
Synchronization of front and rear lifting mechanism
Sensor accuracy: higher than trade level 3 standard
Weight accuracy: ±2 kg (120mm×120mm section)
Type of weighing system
Integral roll table weighing
Roller lifting weighing
Frame lifting weighing
