中板分厂2300劳特式轧机于83年8月安装了一套“幕状层流控制冷却装置”。该装置安装在轧机工艺线上,位于轧机机后,全长10米左右[照片1]结构紧凑,冷却能力适当,调节、控制系统灵活。其上部采用三组层流冷却箱,相隔1.7米,上部冷却流量为320m~2/时。下部采用喷射冷却形式,共有集管18根,两根为一组;共有扁平式喷咀243只,下部冷却流量为335m~3/时。上下冷却水总管,采用电磁系统操纵气动阀
In mid-plate factory 2300 Lauder mill in August 83 installed a “curtain-like laminar flow control cooling device.” The device is installed in the mill line, located in the mill after about 10 meters in length [Photo 1] Compact structure, appropriate cooling capacity, regulation, control system flexible. The upper part of the three sets of laminar cooling tank, separated by 1.7 meters, the upper cooling flow of 320m ~ 2 / hour. The lower part adopts the spray cooling mode, with a total of 18 headers and two sets of them. There are 243 flat nozzles in total, and the cooling flow rate in the lower part is 335m ~ 3 / h. Cooling water pipe up and down, the use of electromagnetic system to control pneumatic valve
