Description
Technical field
The present invention relates to tubing induction heating device annealing technology field, especially a kind of tubing induction heating device inductor block possessing constant temperature insulated capacity.
Background technology
The load coil of current existing tubing induction heating device inductor block is uniformly distributed, and the sized turns all making every effort to often organize coil when the application in parallel of many groups is identical, to obtain the induction heating power of relative equilibrium in workpiece unit length, as shown in Figure 1: inductor block winding, group 1, group 2, organize 3 physical dimension just as, the number of turn is identical, organize 1 coated under workpiece temperature by basal temperature (room temperature) regularly index rise, comparative high temperature level has been heated to when workpiece moves to group 2, the power that workpiece senses under group 2 is coated still has sufficient energy to carry out heated parts and makes workpiece temperature continuation rising except making up certain heat loss, group 3 is with group 2, workpiece is finally caused to enter inductor block by under traffic direction normal temperature state, move to group 3 traffic direction discharge-end temperature and reach the highest, as shown in Fig. 1 temperature curve, then annealing solid solution is completed along with cooling heat dissipation temperature is progressively down to specified temperature, can not be incubated with constant temperature after solution annealing by user's processing requirement, tubing weave construction, crystalline-granular texture, the many indexs such as extension property can not meet the demands, reduce the quality of product, cannot meet the need of market.
Summary of the invention
In order to the load coil solving existing tubing induction heating device inductor block is uniformly distributed, cannot be incubated with constant temperature after solution annealing, tubing weave construction, crystalline-granular texture, the many indexs such as extension property can not meet the demands, reduce the quality of product, the problem that cannot meet the need of market, a kind of tubing induction heating device inductor block is proposed, which obviate the residual stress of goods after solution annealing, improve seam organization structure, crystalline-granular texture, the many index of extension property, product quality is made to have larger lifting, significantly improve heat treated working efficiency and quality product, meet the need of market.
A kind of tubing induction heating device inductor block, is made up of the first inductor block winding, the second inductor block winding and the 3rd inductor block winding; It is characterized in that: the first inductor block winding, the second inductor block winding and the 3rd inductor block winding are wound in outer surface of workpiece successively along workpiece traffic direction, wherein, first inductor block winding, the second inductor block winding are different with the load coil number of turn of the 3rd inductor block winding, in increasing progressively form.
Beneficial effect: the present invention adopts the different mode of the load coil number of turn of three groups of inductor block windings to eliminate the residual stress of goods after solution annealing, improve the many index of seam organization structure, crystalline-granular texture, extension property, product quality is made to have larger lifting, significantly improve heat treated working efficiency and quality product, meet the need of market.

Embodiment
A kind of tubing induction heating device inductor block, is made up of the first inductor block winding, the second inductor block winding and the 3rd inductor block winding; First inductor block winding 5, second inductor block winding 6 and the 3rd inductor block 7 winding are wound in workpiece 4 outside surface successively along workpiece 4 traffic direction, wherein, first inductor block winding 5, second inductor block winding 6 is different with the load coil number of turn of the 3rd inductor block winding 7, in increasing progressively form.
As Fig. 3, shown in 4, because first inductor block winding 5 number of turn is less, impedance is relative to the second inductor block winding 6, 3rd inductor block winding 7 is much lower, so the electric current flowing through the first inductor block winding 5 is relatively many greatly, so when workpiece 4 is when by the first inductor block winding 5, a higher temperature is heated to very soon by absorbing energy much more relatively from the first inductor block winding 5, when workpiece 4 to the second inductor block winding 6, because the turn ratio first inductor block winding 5 of the second inductor block winding 6 wants many, square-law with its turn ratio rises by its impedance, at identical workpiece, material, when Power supply, a little many induced current of relative first inductor block winding 5 is flow through in second inductor block winding 6, workpiece 4 is caused significantly to reduce at the energy by absorbing during the second inductor block winding 6, temperature rise speed obviously falls slow, by controlling to make workpiece 4 reach the temperature of annealing solid solution craft requirement after by the second inductor block winding 6, when the workpiece 4 reaching temperature enters the 3rd inductor block winding 7 by the second inductor block winding 6, because the 3rd inductor block winding 7 number of turn is more, impedance is higher, can sense that the energy on workpiece 4 is less, to such an extent as to workpiece 4 can only be supplemented by calorific loss during the 3rd inductor block winding 7, and the 3rd inductor block winding 7 is distributed within the scope of a longer geometrical dimension, workpiece 4 is made to have the regular hour by the 3rd inductor block winding 7, thus make workpiece 4 keep in a relatively stable temperature value within a long period, simultaneously by adjusting the speed of workpiece 4, the geometrical dimension of induction heating device power and holding-zone the 3rd inductor block winding 7 meet different process require under soaking time.
