45° Hydraulic Shear for CCM

Technical features and process parameters

.Technical features:

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 :

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

(56,000.00yuan/month*4month=224,000.00yuan)

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.   )
