Description
Technical field
The present invention relates to traction apparatus technical field, be specifically related to a kind of slab cast traction machine.
Background technology
In prior art, the structure of slab cast traction machine includes being driven vertically movable floating by hand screw mechanism
Roller, by the fixing roller of motor-driven rotation, motor is connected through the rotating shaft transmission of reductor with fixing roller, the rotating shaft level of fixing roller
Being arranged on two hold-down supports, hold-down support is fixed with support；Hand screw machine it is provided with between the upper end of two hold-down supports
Structure, hand screw mechanism is connected with elevating lever by support, and hold-down support is longitudinally provided with chute, coordinates and be provided with cunning in chute
Block, elevating lever is fixed with slide block, is rotatably connected to floating axle between the slide block at two ends, and floating axle is provided with dancer.Above-mentioned
Fixing roller is puted forth effort uneven, and the copper coin base of production is flexible.On the other hand, the crystallizer that holding furnace is installed should keep level,
If center is inconsistent with La Ding center, then cast slab change out there will be distortion (or bending).
Plate bending injustice causes strong influence, the control of bad of the milling face depth of cut, and copper to the milling face operation in rear road
Plate bending always has some position milling cutters to be not exposed to, then the milling face work of being accomplished by holds manual flour milling machine polishing, the most both reaches
Less than the effect in milling face (if the oxide skin cleaning of copper steel slab surface is the cleanest, then oxygen in the rolling process in rear road
Change skin easily to stick on roll, cause certain hidden danger to copper Surface Quality of Steel Billet), and staff labor intensity is big.
As Chinese utility model patent (CN 204110998U) discloses a kind of identical tension copper strips traction machine, including by electricity
