Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, assembled inductor of the present utility model comprises inductor shell 1, induction coil 2, furnace lining 3, one pair of water-cooled guide rail 4, described induction coil 2 is placed in inductor shell 1, described furnace lining 3 forms for carbofrax material sintering is prefabricated, furnace lining 3 is placed in induction coil 2, and described one pair of water-cooled guide rail 4 is placed in the bottom of the inwall of furnace lining 3.When inductor works, workpiece 8 to be heated enters from one end fire door of inductor, lower end and water-cooled guide rail 4 contact friction, number of repetition is many, and easily to cause the tube wall of water-cooled guide rail 4 to be ground logical, the ejection of internal cooling water causes equipment breakdown, in order to prevent above-mentioned situation, at austenite stainless pipe and the absorption surface place pyrolytic coating nickel chromium triangle borosilicate alloy powder of water-cooled guide rail 4, form one deck wearing layer to reach the object extending guide rail service life.The utility model furnace lining 3 forms for carbofrax material sintering is prefabricated, is assemblied in induction coil 2.As shown in Figure 2, in order to reach better insulation, insulation effect, the heat-insulation layer 5 that aluminosilicate material is made can be laid between furnace lining outer wall and induction coil inwall.The utility model furnace lining 3 forms for carbofrax material sintering is prefabricated, when somewhere furnace lining occurs damaged, can carry out the new furnace lining of dismounting and change at the scene.When inductor is longer, adopt segmented furnace lining, the effect be better convenient for changing can be obtained, described segmented furnace lining splices with male and female seam between adjacent two-stage furnace lining, the oxide skin come off to prevent surface of the work falls on induction coil from gap, is in harmonious proportion adhesive filleting at the seam crossing of furnace lining inner circle with quartz sand.
Inductor coil forms by conducting electricity copper tube coiling, and inductor induction heating current has kelvin effect, and induced-current heats to core gradually by workpiece is outer.In a certain section of inductor, it is inversely proportional to the power density of workpiece heat and the pitch of turn of inductor coil, and more small-power density is larger for pitch of turn.Fire door due to inductor two ends is unlimited, and due to air exchange, heat insulation effect is poor, and the loose magnetic phenomenon at fire door place, must occur that in heating process the two ends temperature of workpiece to be heated is low, the situation that medium temperature is high, this phenomenon is especially obvious when long bar heating.As shown in Figure 3, in order to solve the problem, induction coil 2 of the present utility model is divided into head 5, stage casing 6, afterbody 7 on inductor feedstock direction, and the pitch of turn of described head 5 and afterbody 7 coil is less than the pitch of turn of stage casing 6 coil.Namely coil two ends pitch of turn is compared mid portion pitch of turn and is diminished to add high power density, makes up the temperature caused because of air exchange and loose magnetic phenomenon and declines, adopt above-mentioned technological means to make whole workpiece homogeneous temperature, ensure that crudy.In order to obtain better even temperature effect, wherein the head 5 of induction coil and afterbody 7 become 1.2 to 1.5 times that the length of pitch of turn part is workpiece end face diameter to be heated.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
