Technical features and process parameters
1.The racks and cylinder are both with internal water cooling, increasing the life of the blades and seals.
2.Four edges of the blade can be rotated , increase the usage rate of the blade (about 50 to 80 thousand times per blade)
3.Due to adopting PLC programmable controller control , the system works stably and reliably.
4.Adopt automatic sizing shearing device; Flat shear (diagonal shearing, tiny head, convenient for rolling mill), small size error.
1.The temperature of billet is controlled above 800 degrees,normal shear section: 80 x 80mm ~ 180 x 180mm
2. The shear cylinder diameter:560mm;Instantaneous shearing time:3s
3. Expansion stroke:310mm;Minimum strand distance of continuous casting machine:1200mm
4. The power of pump set:37KW(A dual-use equipment )
Costs comparison between traditional flame cutting (including manual cutting) and hydraulic shear :
hydraulic fluid can be circularly used,ignorant to most of it
cutting nozzle and flame cutting torch
50 to 80 thousand times per blade,ignorant to most of it
hand-cut and Slag removal
1. According to the comparison between traditional flame cutting (including manual cutting) and hydraulic shear, in the case of heat consumption,theuse of hydraulic shear saves about ¥5-¥8 per ton.
2. Cost savings of using the hydraulic shears for each continuous casting machine per month:(25t/h*16h/d*28d/month*5yuan/t=56,000.00yuan)
3. The time to recover the cost of hydraulic shear:4 month
4.Suggestion:If the factory have used continuous casting and rolling project,it had batter use hydraulic shear.Reason:(it will save 18s after usinghydraulic shear,the billet temperature is higher ,Increase the yield, reduce the loss of mill equipment, save power. )
