B. components：

1．leveling machine：composed of power part and main machine。

power part：Composed of power foundation, ZS1850 reducer, 280kw DC

frequency motor, distributor, coupling, clutch, connecting shaft and universal shaft and YWZ brake。

main machine：composed of leveling base, forge stand, forge bridge, forge sliding shaft base, top holder, top and bottom holding wheel base 3 units, top and bottom holding wheel 3 units, holding wheel adjust device, 7 leveling rolls, top leveling roll lifting and pressing device, 2 needle reducers, lubrication pumps 4 units and pressing ruler。

leveling roll shaft material 42CrMo, after forge —— process —— tempering —— process —— quenching —— process。

can control leveling speed by DC frequency motor。

it adopts power distributor, coupling cover connected to universal shaft, leveling rolls are with power, same line speed, to decrease friction and get better leveling quality。

leveling ends adopts 1 set of rolling machine bearing and 1 set of plain thrust bearing。

it adopts 3 sets of holding rolls, can adjust horizontally and vertically, and holding rolls bearings are seal bearings to prevent oxidation dander。

it adopts worm gear, while 2-level reducer pressing adjust torque big, pressure big, can adjust singly and at same time。

leveling roll adopts mid frequency quenching。

adopts leveling main shaft adopts concentrate oil adding。

Total weight:  approximate 210 ton

2．electrical system：power supply and distribution system：power：Ac380V 50Hz control voltage：Ac220V 50Hz

with control table and DC electrical box；

leveling machine can work backward, working rolls lifting by pressing motor, adjust motor can work singly or at same time, all electrical parts fit GB standard, with alarm stop button on control table, in red to protect operators。

C. lubrication：add oil for main gear box and distributor to bottom gear bottom(gear oil), change oil in per month after start working。

add oil to grease pit for reducer, change oil in per month after start working。

add lubricating grease(butter)for adjust worm and bearing。

add mixed oil(in winter: lubricating grease: engine oil= 1:2, in summer: lubricating grease: engine oil= 2:1) for leveling roll bearing and holding roll bearings, 3 times/shift
