■￠ 250MPM tube rolling train

■￠ 168PQF tube rolling train

　　The major installation has the ring-like heating furnace, the conical roll puncher, 5 to limit moves the core rod PQF continually rolling mill, 3 roller type 14 rack calibrators, 6 roller vertical web roll straightening machine and so on. The PQF tandem rolling unit was the modern seamless steel pipe production vanguard technology centralism manifests, has achieved the seamless steel pipe production continuously, highly effective, moreover had the extremely high mechanization, the automaticity, it was representing the newest technical level which the world seamless steel pipe produces now.

■￠ 258PQF tube rolling train

■￠ 180Assel rolling mill

　　The major installation has the ring-like heating furnace, the cone-shape puncher, the Assel tube rolling-mill, 14 three roller micro tensity calibrator and so on. The Assel rolling mill processing technology and the equipment level are in the similar unit international advanced standard, its craft characteristic has used two diagonal rolling processing technology, namely Assel tube rolling-mill. This unit is suitable in the production the thick wall and the thick wall bushed bearing, the high-pressured furnace tube, the collar tube, drills the tappet and the machinery uses the tube and so on.

■￠ 460PQF continually tube rolling train

　　The major installation has the ring-like heating furnace, the conical roll puncher, 5 to limit moves the core rod PQF continually rolling mill, 3 roller type 14 rack calibrators, 6 roller vertical web roll straightening machine and so on. Is the world first heavy-caliber three roller continually tube rolling-mill production line, is also in the world the biggest heavy-caliber tandem rolling unit. This set of units compare with same caliber's other units, is producing the heavy-caliber high alloy difficult to roll over the distortion variety aspect, has the obvious superiority, its product becoming a useful adult rate is high, the tool consumes low as well as the rolling cost low characteristic, has established this set of unit world first leading position.
