Tube round slab, hot-rolled pneumatic cylinder tubes casting or blooming slab as raw material into the rough rolling mill reheating furnace heating, high pressure water descaling rough rolling material by the cutting head, tail, re-entering the finishing mill,implementation of computer-controlled rolling, and finally rolled after laminar cooling and coiling machine coiling, straight hair curlers. Straight hair volume head, the tail is often a tongue and fishtail, thickness, width less accuracy, edge often wavy, fold, pyramid and other defects. Its volume weight heavier coil inner diameter is 760mm. Straight hair volume by the cutting head, tail cutting, trimming and multi-channel straightening, formation finishing line processing, and then cutting board or heavy volume, it becomes: hot rolled steel plates, flat hot rolled coil slitting and other products. The entire volume of the hot-rolled fine pickled to remove oxide scale and oiled Serve hot pickling coils.
The difference between pneumatic cylinder tube and seamless pipe
1, the main features of the seamless steel pipe is welded seam, and can withstand greater pressure. Products can be very rough cast or cold call.
2, the cylinder tube products emerged in recent years, mainly within the hole, the outer wall of tighter tolerances and roughness size.
The characteristics of the pneumatic cylinder tube
1 the outer diameter is smaller.
2 High precision can do small quantities of raw
3 high precision cold drawn finished, good surface quality.
4 steel pipe cross area is more complex.
5 steel pipe superior performance, the metal is relatively dense.
