Accompanying drawing explanation
Fig. 1 is the profile of the assembled induction apparatus of the present invention；
Fig. 2 is the profile of the assembled induction apparatus adding heat-insulation layer of the present invention；
Fig. 3 is the change pitch of turn loop construction schematic diagram of the present invention.
Detailed description of the invention
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, the assembled induction apparatus of the present invention includes induction apparatus shell 1, induction coil 2, furnace lining
3, one pair of water-cooled guide rail 4, described induction coil 2 is placed in induction apparatus shell 1, and described furnace lining 3 is carbonization
Silicon materials sintering is prefabricated to be formed, and furnace lining 3 is placed in induction coil 2, and described one pair of water-cooled guide rail 4 is placed in stove
The bottom of the inwall of lining 3.When induction apparatus works, workpiece 8 to be heated enters from one end fire door of induction apparatus,
Lower end contacts friction with water-cooled guide rail 4, and number of repetition to be easily caused the tube wall of water-cooled guide rail 4 and ground logical,
Internal cooling water ejection cause equipment breakdown, in order to prevent above-mentioned situation, water-cooled guide rail 4 austenite not
Pyrolytic coating nickel chromium triangle borosilicate alloy powder at rust pipe and absorption surface, forms one layer of wearing layer and leads to reach prolongation
The purpose in rail service life.Furnace lining 3 of the present invention forms for carbofrax material sintering is prefabricated, is assemblied in the line of induction
In circle 2.As in figure 2 it is shown, in order to reach preferably to be incubated, insulation effect, can be in furnace lining outer wall and sense
Answer and between coil inwall, lay the heat-insulation layer 5 that aluminosilicate material is made.Furnace lining 3 of the present invention is carbofrax material
Sinter prefabricated forming, when breakage occurs in somewhere furnace lining, the new furnace lining of dismounting and change can be carried out at the scene.Work as sense
When answering device longer, use stagewise furnace lining, the effect being preferably convenient for changing, described stagewise can be obtained
Furnace lining splices with male and female seam, for the oxide skin preventing surface of the work from coming off between adjacent two-stage furnace lining
Fall to from gap on induction coil, furnace lining inner circle seam crossing with quartz sand be in harmonious proportion binding agent filleting.
Inductor coil forms by conducting electricity copper tube coiling, and induction apparatus induction heating current has kelvin effect,
Faradic current is gradually heated up to core by workpiece outer layer.Its power to workpiece heat in a certain section of induction apparatus
Density is inversely proportional to the pitch of turn of inductor coil, and pitch of turn more small-power density is the biggest.Due to induction apparatus two ends
Fire door is unlimited, and due to air exchange, heat insulation effect is poor, and the scattered magnetic phenomenon at fire door, is adding
Necessarily occurring in thermal process that the two ends temperature of workpiece to be heated is low, the situation that medium temperature is high, this phenomenon is being grown
It is especially apparent during bar heating.As it is shown on figure 3, in order to solve the problems referred to above, the induction coil 2 of the present invention
Induction apparatus feedstock direction is divided into head 5, stage casing 6, afterbody 7, described head 5 and afterbody 7 coil
Pitch of turn is less than the pitch of turn of stage casing 6 coil.I.e. coil two ends pitch of turn is compared mid portion pitch of turn and is diminished to strengthen merit
Rate density, makes up the temperature caused because of air exchange and scattered magnetic phenomenon and declines, use above-mentioned technological means to make
Workpiece bulk temperature is uniform, it is ensured that crudy.In order to obtain more preferable even temperature effect, the wherein line of induction
The head 5 of circle and afterbody 7 become 1.2 to 1.5 times of the workpiece end face diameter a length of to be heated of pitch of turn part.
In addition to the implementation, the present invention can also have other embodiments, all employing equivalents or equivalence
The technical scheme that conversion is formed, all falls within the protection domain of application claims.
