Abstract
The utility model provides a roller quenching inductor, which belongs to the induction heat treatment equipment field. The roller quenching inductor comprises a power frequency induction coil in which both the upper layer and the lower layer are controlled by an independent source, and an isolation layer is arranged between the upper layer induction coil and the lower layer induction coil. The utility model has the advantages that the quench hardening layer of the roller is deepened, the heat treatment quality at the through quenching layer position is ameliorated, the service life of the roller is prolonged, and the processing cost of the roller is reduced.
Description
Technical field
The utility model belongs to the Induction Heat Treatment Equipment field, relates in particular to the quenching inducer of large-scale roller.
Background technology
Breaker roll carries out induction quenching and mainly still adopts single power frequency heat hardening induction coil and common power frequency to add the medium frequency quenching induction coil in the market, and single power frequency heat hardening induction coil is subjected to the restriction of its hot zone width, power supply control and equipment peak power, under the prerequisite that guarantees the quenching quality, working roll for Cr2, MC3 series is quenched deep layer about 15-20mm, intermediate roll is quenched deep layer about 20-25mm, and quenching rear surface hardness value fluctuates generally in 4HSD.Power frequency adds the medium frequency quenching induction coil, and in second induction coil, because the effect of Medium frequency induction circle is mainly insulation, the heat of the main abutment surface of expansion of its diathermanous layer depth is undertaken by heat conducting mode.Common roll is along with the roll raising in work-ing life, and user's breaker roll deep layer of quenching requires more and more highlyer, and single power frequency heat hardening induction coil and common power frequency add the medium frequency quenching induction coil and be difficult to meet the demands.
Summary of the invention
The purpose of this utility model is a kind of roller quenching induction coil that can overcome the deficiencies in the prior art of design.
For achieving the above object, the technical solution of the utility model is: roller quenching inducer, have induction coil, and induction coil is made of upper strata induction coil and lower floor's induction coil, and upper and lower layer induction coil all is the line-frequency induction circle by independent current source control.
The number of turn of described upper strata induction coil is the 9-12 circle, and the number of turn of lower floor's induction coil is the 7-10 circle.
Be provided with insulation layer between the described upper and lower layer induction coil.
The beneficial effects of the utility model are: can deepen the quench-hardened case of roll greatly, improve the thermal treatment quality at quench-hardened case position, improve roll work-ing life, reduce the Roller Machining cost.
Description of drawings
Fig. 1 is the structural representation of inductor block among the present invention.
Among the figure, 1 is the upper strata induction coil, and 2 is lower floor's induction coil, and 3 is insulation layer.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Roller quenching inducer, has induction coil, induction coil is made of upper strata induction coil 1 and lower floor's induction coil 2, upper and lower layer induction coil all is the line-frequency induction circle by independent current source control, the number of turn of upper strata induction coil 1 is 10 circles, the number of turn of lower floor's induction coil 2 is 8 circles, is provided with insulation layer 3 between the upper and lower layer induction coil.
