Description
Technical field
The utility model relates to a kind of roll locating device, is specifically related to the locating mechanism of roll in a kind of ultra-large type roll induction hardening machine.
Background technology
Roll is the strength member on Steel Mill's rolling mill, and the pressure that produces when utilizing a pair of or one group of roll rolling rolls the stone roller steel.It mainly bears the sound load when rolling, wearing and tearing and influence of temperature variation.The roll kind is a lot, and roll kind commonly used at present has cast steel roll, grain roll and forging roller three major types, also has a small amount of hard alloy roll at bar and shape mill.
Finished product cold-rolled steel sheet roll is the product of high added value, high technology content, in the manufacturing, the hard surfacing of roller body is the operation of most critical, quenching inducer in the induction quenching then is the important means that realizes this operation, is to reach all necessarieses of qualified roll of hardness of roll body and quench-hardened case.Induced surface hardening is to utilize electromagnetic induction principle, in the galvanic circle of closure, connect alternating-current and produce alternating magnetic field, thereby produce the current vortex breaker roll and the surface is arranged to internal heating, roll crown is quickly heated up to more than the stagnation point, realize hard-faced a kind of processing method, and ferromagnetic substance is exactly the roll that needs quenching.
Though the induction hardening process of roll has been sent out the long time, since with high content of technology, so in development, still there are many technological deficiencies., in the induction hardened course of processing, though its hardening capacity is very good, very easily forms bigger thermal stresses and structural stress when quenching and cause distortion to close crackle at existing roll.Comparatively thorny technical problem during this phenomenon, abroad in document and the Chinese literature, also few about the report that solves above-mentioned induction quenching problem, there is great technological gap in visible present domestic external cooling Steel Roll induction quenching field, real technical problem for needing to be resolved hurrily at present.
The utility model content
The purpose of this utility model is to overcome the defective that exists in the prior art, the locating mechanism of roll in a kind of ultra-large type roll induction hardening machine is provided, be used for solves the prior art cold roll and quench and easily form bigger thermal stresses and structural stress and cause distorting and close the problem of crackle.
For achieving the above object, the technical solution of the utility model is the locating mechanism of roll in a kind of ultra-large type roll induction hardening machine of design, it is characterized in that, described roll locating mechanism comprises board, described board be provided with axial clamping location roll on, following thimble, on described, be provided with heating inductor and cooling spraying quenching device between the following thimble, described heating inductor and cooling spraying quenching device are sheathed on outside the roll, side at described heating inductor and cooling spraying quenching device is provided with connecting arm, described connecting arm is slidingly matched by vertically disposed guide rail on slide block and the board sidewall, on described slide block, also be connected with the orienting sleeve that is sheathed on the roll, described orienting sleeve is used for roll is positioned the thermal center (-tre) that adds of heating inductor, and carries out vertical guiding for heating inductor in the process of moving up and down.
Optimized technical scheme is in the utility model, and described heating inductor is 400mm/min in described roll wait the to quench translational speed at position.
Optimized technical scheme also has in the utility model, also is provided with on the described board to drive the drive unit that described upper and lower thimble rotates.
Optimized technical scheme also has in the utility model, and described heating inductor and cooling spraying quenching device are circular.
Advantage of the present utility model and beneficial effect are: the locating mechanism of roll in this ultra-large type roll induction hardening machine, can make roller surface hardness reach 62-63HRC, effective case depth 30mm, not only hardness and hardened layer meet technical requirements, and because cooperating of upper and lower thimble and orienting sleeve makes this roll deformation also successfully control in the 0.5mm that requires.Simultaneously, the roll of specification of the same race, adopt about 50 degree of traditional every consumed power of integral quenching, and the induction hardening process that the utility model adopts only carries out hot-work at the position to be quenched on the roll, therefore every consumed power 2 degree only, energy-conservation 96%, under the situation of mass production, the energy consumption of saving is huge, and the economic benefit of creation is considerable; Simultaneously, the locating mechanism of roll in the roll induction hardening machine of the present utility model has been started the beginning for the induction quenching of ultra-large type roll from now on, has filled up quench one blank of technology of induction.
