China Continuous Casting Rolling Hydraulic Shear Rolling Mill

Technical features and process parameters

.Technical features:

1.The racksand cylinder are both with internal water cooling, increasingthe life of the bladesand 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 toadoptingPLCprogrammablecontroller control,thesystemworksstablyandreliably.

4.Adopt automatic sizingshearing device; Flat shear (diagonal shearing,tinyhead, convenient for rolling mill), small size error.

1.The temperature ofbilletis controlled above 800 degrees,normal shear section: 80 x 80mm ~ 180 x 180mm

2.The shear cylinder diameter:560mm;Instantaneous shearingtime:3s

4.Thepowerofpump set:Telecommunication & Broadcasting 37KW(Adual-useequipment) Costscomparisonbetween traditional flame cutting (including manualcutting) and hydraulic shear:

1.According to the comparisonbetween traditional flame cutting (including manualcutting) and hydraulic shear, in the case of heat consumption,theuse ofhydrLaser Equipment aulic shearsaves about ¥5-¥8 per ton.

2.Costsavingsofusingthe hydraulic shearsforeach continuous casting machineper month:(25t/Instrument Box h*16h/d*28d/month*5yuan/t=56,000.00yuan)

3.The time to recover the costofhydraulicshear:4 month

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

4.Suggestion:If the factory have usedcontinuous casting and rollingproject,it had batter usehydraulic shear.Reason:(it will save 18s after usinghydraulic shear,thebillet temperature is higher,Increase the yield, reducethelossofmill equipment, savepower.)
