our products: 1, hot rolling mill 2, cold rolling mill 3,2-roller horizontal rolling mill 4,2-roller vertical rolling mill 5,3-roller pipe rolling mill /tube rolling mill 6, 650 3-roller rolling mill 7, 4-roller planetary rolling mill the main product line: 1, welded pipe product line 2, seamless product line 3, bar product line 4,round bar ,steel wire mill 5,medium plate mill 6,hot-rolled band steel mill company honor: the first nationalprize for invention and progressin Science and Technology 550 H-Mill Work Stand composed by the mill rod assembly, roller assembly, mill base assembly and mill screwdown devices. Mill rod assembly composed by the 4 high-strength and high-rigidity alloy steel bar (rod material for the Mill: 42CrMo, Heat Treatment Hardness: HB286-340), 2 left supporting ,2 right supporting, 4 left adjusting nuts ,4 right adjusting nuts and 4 elastic damping etc., or left and right rotating adjustment nut were installed in the four bearing blocks, the 4 elastic damping balance the up and down bearing seats, pressing the top of the device installed in the bar, rolling mill rod assembly installed in the mill base, the rail seat at the lower of mill base, with anchor bolts fixed to the construction, based on the work machine for the rolling mill bearing seat, etc., and the use of in-orbit seat of the locking cylinder working machine will be rolling mill seat fixed to the seat rails to bear the rolling force, rolling mill traverse will release the lock cylinder until the mill to adjust a good location, with the locking cylinder will rack fixed to the rail seat. Roller assembly composed by the upper and lower work rolls, comprising the upper and lower work rolls, bearing seat, bearings and so on, roll a low-Cr-Mo chill cast iron ductile material, bearing the ZG35. Bearings include: four-row cylindrical roller bearings, bi-directional double-row tapered roller thrust bearings, bi-directional double-row tapered roller bearing thrust roller installed in the operating side, to bear axial force, does not bear radial force. Four-row cylindrical roller bearings rolling force to bear. When the roll diameter and not accompanied by use of roller bearing relative to the rolling line of symmetric adjustment, do not need any pads. Screwdown device installed at the top of the rod mill, composed by the worm wheel, worm drive system, hydraulic motors and artificial handle depressed etc., hydraulic motor drive in the rolling mill rolling mill to achieve the rapid depressed side adjustments to fine-tune the handle by hand. Axial roll adjustment using gear / worm structure, installed on the operating side. Roll balance with a balance of elastic damping, elastic damping installed on the upper and lower roller bearing between the bearing and thread to eliminate gaps, ensure maximum rigidity rack.
