Abstract
The invention provides a design method for adjustment of a driving roller of a thick slab continuous casting machine and belongs to the technical field of a slab continuous casting machine. The design method comprises the following steps: manufacturing 8-12 adjusting mechanism positioning blocks (3) and drilling a 30-60 degree bevel groove on an edge part; welding the positioning blocks (3) on a driving beam in a position being 100-220mm away from two sides of the driving beam; removing a supporting block (1), removing all inner gaskets in the original adjusting mechanism and mounting the supporting block (1) again; manufacturing a gasket (2) having a shape of a Chinese character 'Tu' for adjusting a roller gap value of the driving roller; manufacturing a press plate; placing the manufactured gasket (2) having the shape of the Chinese character 'Tu' on the driving beam and placing the press plate on the gasket (2); and fastening the press plate and the gasket (2) having the shape of the Chinese character 'Tu' with the driving beam by using a bolt. The design method has the advantage that the adjustment for the roller gap value of the driving roller is more easy and convenient.
Description
Technical field
The invention belongs to sheet billet continuous casting equipment technical field, the method for designing that particularly a kind of driven roller of slab CC machine machine is adjusted.For a kind of method for designing of brand-new driven roller open degree adjustment mechanism.
Background technology
Easily there is bulge in slab CC machine machine, this can cause certain harmful effect to Inner Quality of Billet.Segment roll gap value plays vital effect to the internal soundness of slab CC machine machine as can be seen here.In general, segment roll gap value the most overproof position mainly concentrates on the driven roller of fan-shaped section, so the guiding mechanism of driven roller roll gap is particularly important.For the first 400mm of Qin slab CC machine machine, there is defect in original driven roller roll-separating mechanism, and 3D spray is located at guiding mechanism top, and space is too compact, causes some fan shaped section driving roller guiding mechanisms to use.For this reason, bonding apparatus actual conditions, design a set of brand-new driven roller open degree adjustment mechanism.
Summary of the invention
The method for designing that the object of the present invention is to provide a kind of driven roller of slab CC machine machine to adjust.Solved the design defect of former guiding mechanism, made the adjustment of driven roller roll gap more convenient, more effective.The present invention, in conjunction with former design, has increased external roll-separating mechanism on intrinsic basis,
Specific design method step is as follows:
1, make guiding mechanism locating piece 8-12 part, internal thread is established in centre, and 30-60 degree groove is beaten by limit portion, and material such as requires, as driving beam to be easy to welding, S355J2G3,1.4571DIN, S235JRG2 steel or 16Mn steel etc. with fan-shaped section.
2, locating piece is welded on and drives on beam, position drives 100-220mm place, beam both sides in distance, leaves sufficient space and facilitates inspection operation.
3, remove back-up block, former guiding mechanism internal gasket is Removed All, return dress back-up block.
4, make " native font " the pad 4-12 part for adjusting driven roller gap values between rollers, material is stainless steel, and thickness is 0.2mm-0.5mm.
5, make pad pressing plate, thickness of compressive plate is 6-16mm.
6, " native font " pad of newly making is placed in and is driven on beam, bleed off pressure plate above.
7, with bolt, pressing plate, " native font " pad and driving beam are tightened together.
The invention has the advantages that: solved due to the not enough problem that cannot adjust driven roller roll gap causing of space for maintenance.And make the adjustment of driven roller gap values between rollers easier, faster.
Accompanying drawing explanation
Fig. 1 is former driven roller roll-separating mechanism figure.Wherein, back-up block 1, " native font " pad 2, locating piece 3.
Fig. 2 is the welding position figure of locating piece.
Fig. 3 is " native font " shim size schematic diagram.
Fig. 4 is pad pressing plate size schematic diagram.
The specific embodiment
1, make 8 guiding mechanism locating pieces 3, the long and wide 36mm that is, high 30mm, at central spot processing M8 through hole whorl, material is 16Mn steel, GB1591-88 standard.
2, locating piece 3 is welded on and is driven on beam by the size of Fig. 2, position drives 100mm place, beam both sides in distance, leaves sufficient space and facilitates inspection operation.
3, remove back-up block 1 in Fig. 1, former guiding mechanism internal gasket is Removed All, return dress back-up block 1.
4, by Fig. 3 size, make 10 " native font " pads 2 for adjusting driven roller gap values between rollers, material is 0Cr18Ni9 stainless steel, GB1220-92 standard, and thickness is 6 of 0.2mm, 0.3mm4 part.
5, press Fig. 4 size and make pressing plate, thickness of compressive plate is 8mm, and material is 0Cr18Ni9 steel, GB1220-92 standard.
6, " native font " pad 2 of newly making is placed in and is driven on beam, bleed off pressure plate above.
7, by M8 bolt, pressing plate, " native font " pad 2 and driving beam are tightened together.Guarantee that driven roller gap values between rollers is within the scope of permissible variation.
As experience after a period of time, driven roller gap values between rollers changes again, unclamps M8 bolt, opens pressing plate, by increasing or reduce " native font " pad 2, realizes the adjustment of driven roller gap values between rollers.
Claims (2)
