Description
Technical field
The utility model belongs to steel rolling equipment field.Can be used for the stainless steel annealing pickling band of the difficult distortion of rolling.
Background technology
Due to features such as stainless steel yield strength are high, and resistance of deformation is large, in rolling 2 be or when 3 are stainless steel, traditional production equipment mostly is 20 rollers and eighteen-high mill especially.Due to 20 rollers and eighteen-high mill cost of investment is large, maintenance cost is high, the enterprise that some scales are less is just used four rollers or six-high cluster mill to produce stainless-steel cold-rolling band, but normal four-roller or six-high cluster mill are because working roll roller footpath is larger, with respect to 20 rollers and eighteen-high mill, the reduction ratio of a rolling process is less, often need intermediate annealing, and then improve production cost.
Utility model content
In order to improve four rollers or the six-high cluster mill reduction ratio in a rolling process, reduce intermediate annealing link, develop a kind of new type stainless steel. corrosion resistance continuous cold rolling process and unit thereof.
The utility model is to adopt following scheme to realize: a kind of new type stainless steel. corrosion resistance continuous cold rolling process, comprises following operation: through uncoiler to band uncoiling.The aligning end to end coil of strip with straightener.Cut off defective band with hydraulic shear.What with welding machine, band is sheared welds end to end.Band through 1 ﹟ jockey pulley, entry loop, 2# jockey pulley group, after the rolling of tandem rolling unit, enter cleaning drying machine group dry.Band after oven dry through 3# jockey pulley group enter outlet looping, from outlet looping out by 4# jockey pulley, enter crimping machine through cutting to cut.When coil diameter reaches required when big or small, band is cut band cutting the place of cutting.Cut rear band and unload coiling machine by coil stripping car.
A kind of unit of new type stainless steel. corrosion resistance continuous cold rolling process, comprise the following equipment being linked in sequence: uncoiler, straightener, hydraulic shear, welding machine, 1 ﹟ jockey pulley, tandem rolling unit, 4# jockey pulley, cut cut, crimping machine, be characterized in: the entry loop that addition sequence is connected between 1 ﹟ jockey pulley and tandem rolling unit and 2# jockey pulley group, between tandem rolling unit and 4# jockey pulley, add the cleaning, drying unit, 3# jockey pulley group, the outlet looping that are linked in sequence.
Tandem rolling unit can adopt the mode of multi-frame four roller tandem rolling units connected in series.In the utility model, tandem rolling unit adopts the mode of six frame four roller tandem rolling units connected in series.Tandem rolling unit also can adopt the mode of multi-frame six roller tandem rolling units connected in series.Tandem rolling unit adopts path roller.Tandem rolling unit adopts backing roll central driving.
The difference of the utility model and conventional stainless steel continuous cold rolling process unit is:
In order to improve the reduction ratio of milling train and to prevent that the outlet of backing roll transmission slip milling train from adopting hightension, so cleaning, drying unit and jockey pulley are set in milling train outlet.In order to reduce roll-force, improve drafts, the working roll of milling train adopts pony roll footpath, the bottleneck problem during for fear of pony roll footpath transmitting torque, milling train transmission adopts backing roll central driving.
By adopting above technical scheme, make some scales can not use 20 rollers and this equipment that class cost of investment is large, maintenance cost is high of eighteen-high mill compared with little enterprise, use normal four-roller or six-high cluster mill just can produce stainless-steel cold-rolling band, thereby significantly reduced production cost.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of new type stainless steel. corrosion resistance continuous cold rolling process of the utility model flow process.
In figure: 1, uncoiler, 2, straightener, 3, hydraulic shear, 4, welding machine, 5,1# jockey pulley, 6, entry loop, 7,2# jockey pulley group, 8, tandem rolling unit, 9, cleaning, drying unit, 10,3# jockey pulley group, 11, outlet looping, 12,4# jockey pulley, 13, cut and cut, 14, coiling machine.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further: this unit has adopted the full technology mode of endless rolling continuously, unit entrance is provided with two uncoilings, be provided with welding machine can welding front and back two coiled strips simultaneously end to end, realize continuously and producing, tandem rolling unit is six frame four roller series connection forms.The entrance of tandem rolling unit, outlet are equipped with kink, to guarantee that milling train is not shut down in the time that entrance welding and outlet are cut.Entrance and the outlet of tandem mill arrange jockey pulley, to improve the tension force of tandem mill entrance and outlet, also adopt hightension between frame simultaneously, improve the percentage pass reduction of milling train by hightension.Cause milling train outlet jockey pulley to skid for fear of milling train outlet strip surface emulsion residue, establish cleaning, drying unit in milling train outlet.The type of milling train adopts four-high mill, and in order to improve milling train percentage pass reduction, working roll adopts pony roll footpath, and in order to avoid the bottleneck of little working roll when the transmitting large torque, the milling train kind of drive adopts backing roll central driving simultaneously.
Fig. 1 is schematic diagram of the present utility model.Hot rolling raw material coil of strip carries out uncoiling by uncoiler 1, band carry out, after straightening processing, cutting off defective band by hydraulic shear 3 at straightener 2 end to end, then by welding machine 4, band is welded end to end, to realize continuous production.Band after welding 5 enters entry loop 6 after by 1# jockey pulley.Band enters six frame four roller tandem rolling unit 8 continuous rollings by 2# jockey pulley group 7 from entry loop 6 out, is rolled into the cold-strip of desired thickness.Band enters outlet looping 11 by cleaning, drying unit 9,3# jockey pulley group 10 from tandem rolling unit 8 out successively.Band from outlet looping 11 out again by 4# jockey pulley 12, cut and cut 13, enter coiling machine 14.Coiling machine 14 is strip coil rolling, and when coil diameter reaches required when big or small, band is cut cutting 13 pairs, the place of cutting.Band after cutting unloads coiling machine by coil stripping car.
In this technical process, be stressed that in order to ensure the ability of depressing of tandem rolling unit 8 and avoid live-roller to skid, 2# jockey pulley group 7 is set before tandem rolling unit 8, and the rear 3# of the setting jockey pulley of tandem rolling unit 8 group 10 is to guarantee that tandem rolling unit entrance and outlet have enough large tension force.Because band exit surface has emulsion residue, skid for fear of milling train outlet jockey pulley simultaneously, between tandem rolling unit 8 and 3# jockey pulley group 10, be also provided with cleaning, drying unit 9.
Tandem rolling unit 8 can adopt the mode of multi-frame four roller tandem rolling units connected in series.In the utility model, tandem rolling unit adopts the mode of six frame four roller tandem rolling units connected in series.Tandem rolling unit also can adopt the mode of multi-frame six roller tandem rolling units connected in series.Tandem rolling unit adopts path roller.Tandem rolling unit adopts backing roll central driving.
The above; it is only the preferably specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; those skilled in the art are within the scope of the disclosed method of the utility model, within according to method scheme of the present utility model and design of the present utility model thereof, equivalents all should be encompassed in protection domain of the present utility model in addition.
