Description
Technical field
The utility model belongs to a kind of equipment of metal fever processing usefulness, specifically a kind of heating unit that is used to process cold roll.
Background technology
Entered since 90 mid-terms in generation of last century, the demand of China's band steel is increasing, the production and the tempo of cold-reduced sheet are also more and more faster, roll is the main consumption spare part of cold-reduced sheet manufacturing enterprise, the quality of cold roll quality directly has influence on the surface quality of band steel, therefore, to the cold roll specification of quality than higher.Traditional cold roll uses 9Cr2Mo, 86CrMoV7 material processing and fabricating always, because the alloying level of this class material is lower, therefore depth of hardening, effective working lining of abundant roll generally at 12 millimeters (radial directions), must heavily quench 1～2 time, each heavily quenching not only needs certain thermal treatment expense, and the depth of hardening of 5 millimeter is lost in the thermal treatment meeting at every turn, in addition, roll is easy deformation also, is difficult to satisfy the Geometrical Tolerance Principle of precision roll.
From the later stage nineties in last century, domestic MC3, MC5, MC8, semi-high speed steel, the high speed steel cold roller succeeded in developing in succession, and introduced external " double frequency induction quenching equipment " its quench-hardened case and increase, but also greatly differ from each other with requirement that design of Roller effectively uses layer depth need reach more than 30 millimeters.Have also simultaneously that residual austenite is excessive in the metallographic structure, martensite is thick, internal residual stress is inhomogeneous, problem such as easily produce the helix wheel band, wear no resistance, thus make the work-ing life of cold roll low.
In the prior art, also have the method for the gradual heating in a kind of part cold roll to be processed, utilize an annular heating ring, be enclosed within on the cold roll to be heated, during work, move on limit heating, limit, cool off on the limit.Therefore tend to occur heating problems such as irregular, thereby have influence on the quenching quality of cold roll.
Summary of the invention
The purpose of this utility model is to design a kind of cold roll integral induction heat and deep quenching shield-shape induction device, to improve the depth of hardening zone of cold roll, prolongs the work-ing life of cold roll.
According to the technical scheme that the utility model provides, inductor block is shield shape, and, have two at least; Inwall at inductor block is provided with several grooves equably, and coil is arranged in groove; The polylith inductor block surrounds a cylindrical space that can hold the cold roll of waiting to quench.
The screw-type regulating mechanism is set on inductor block.In the screw-type regulating mechanism, the axis of regulating bolt is parallel with the diameter of inductor block, is regulating the end connection roller that bolt points to the center of circle of inductor block.Coil is formed by the open tube coiling.Inductor block is installed on the frame of quenching machine, is provided for inductor block is moved to the pushing mechanism on the cold roll surface of waiting to quench between the frame of inductor block and quenching machine.
The utility model has the advantages that: owing to be provided with a kind of inductor block of shield shape, 2 or 3 or how such inductor block are surrounded a round shape near the cold roll of waiting to quench, cold roll is trapped among middle, whole heating, compare with original gradual heating means, stop the uneven problem of heating, effectively improved the depth of hardening of cold roll, prolonged the work-ing life of cold roll.
Description of drawings
Fig. 1 is a structure iron of the present utility model.
Embodiment
As shown in Figure 1: inductor block 7 is curved, has 3; Inwall at every inductor block 7 is provided with several grooves 6 equably, and the coil 5 that is formed by the open tube coiling is set in groove 6; 3 inductor blocks 7 surround a cylindrical space that can hold the cold roll 3 of waiting to quench with the central angles of 120 degree, are not putting into before the cold roll 3, and every 7 of inductor block is open state, so that cold roll 3 enters.The screw-type regulating mechanism is set on inductor block 7.In the screw-type regulating mechanism, the axis of regulating bolt 2 is parallel with the diameter of inductor block 7, is regulating the end connection roller 1 that bolt 2 points to the center of circle of inductor block 7.3 inductor blocks 7 are installed on respectively on the frame of quenching machine, are provided for inductor block 7 is moved to the pushing mechanism on cold roll 3 surfaces of waiting to quench between the frame of every inductor block 7 and quenching machine.This pushing mechanism can be cylinder piston mechanism, electric pushrod mechanism, leading screw and nut mechanism, pinion and rack or worm-and-wheel gear etc.φ among the figure is the diameter of cold roll 3.
During use, cold roll to be quenched 3 is positioned on the support, send into the position at 3 inductor block 7 places, restart driving mechanism, make 3 inductor blocks 7 simultaneously slowly near cold roll 3, and then rotate and regulate bolt 2, roller 1 is contacted with the surface of cold roll 3, with this spacing of adjusting every inductor block 7 and cold roll 3, make every inductor block 7 all equidistant, with the homogeneity of guaranteeing to heat with the surface of cold roll 3.Energising then is by the magnetic field induction heats cold roll 3 of coil 5 generations, after being heated to the temperature of setting, cool, realize the purpose of quenching, by test, this quenching mode can make the depth of case-harden of cold roll 3 reach 40～65 millimeters, meets the service requirements of cold roll 3 fully.
