Abstract

A novel inductive sintering furnace is mainly composed of a furnace cover, a furnace body and a furnace lining, wherein the outer wall of a body of the furnace lining is induction coils, the middle of the body of the furnace lining is a fireproofing material layer, and the inner wall of the body of the furnace lining is a heating element. The heating element is in a cylinder structure formed by stacking of annular metal boards from bottom to top. Due to the fact that a traditional heating element in an integrated type cylinder shape is replaced by the heating element in a cylinder shape formed by the stacking of the annular metal boards, when partial damage of the heating element in a cylinder shape formed by the stacking of the annular metal boards occurs, damaged parts can be directly replaced, the problem of resource waste caused by replacing of the integrated heating element can be avoided, and therefore production cost can be effectively saved, and production efficiency can be effectively improved.

Description

A kind of novel induction sintering furnace
Technical field
The utility model relates to a kind of sintering equipment for field of powder metallurgy, specifically a kind of novel induction sintering furnace.
Background technology
Sintering is the process that granular material is changed into DB, is a kind of traditional processing technology.In sintering process, induction sintering furnace is a kind of very common sintering equipment, in induction sintering furnace, the heater of furnace lining is a very crucial position, the existence of induction sintering furnace heater, in the carrier that transforms to heat energy as electric energy, can effectively avoid sinter to contact and pollute with refractory material on the one hand, can guarantee on the other hand the uniformity of induction sintering furnace internal atmosphere, temperature.For traditional induction sintering furnace; the heater of its inner furnace lining is the tubular integrated; the heater conduction of this whole shape evenly; good barrier property; but simultaneously; when sintering furnace long-term when in running order; the suffered variations in temperature of heater is floated larger; the heater local deformation very easily occurs causing by being heated inequality, even crackle occurs; the phenomenons such as local fragmentation are when above-mentioned condition occurring; generally traditional induction sintering furnace can only be changed whole taking-up of heater; this has just increased production cost greatly, and the replacing of monolithic devices heater is very inconvenient, usually can cause manpower; the wasting of resources of the each side such as material resources.
The utility model content
For the problems referred to above, the utility model provides a kind of novel induction sintering furnace, this device can effectively solve the waste of material problem that traditional induction sintering furnace heater integral replacing causes, simultaneously, the heater of this induction sintering furnace is changed convenient succinct, design and produce simply, can enhance productivity greatly, save production cost.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be: a kind of novel induction sintering furnace, mainly formed by bell, body of heater, furnace lining, the body outer wall of described furnace lining is induction coil, middle for refractory masses, inwall are heater, described heater is the tubular structure that annular metal sheet stacks together from bottom to up.
Described induction coil skin has protective device.
The refractory masses of described furnace lining is comprised of existing refractory materials such as refractory brick or fire-resistant cottons.
The diameter of the annular metal sheet of described heater is increased to the top successively by the bottom, guarantees that namely heater has certain angle by the bottom to trend and the vertical direction at top.
Be filled with oxidation zircon sand between the annular metal sheet of described heater and the refractory masses.
Described induction coil is connected with external power source.
The beneficial effects of the utility model are: replace the one-piece type heater of tubular with annular metal sheet, when certain position in the heater crackle, fragmentation etc. occur and damages phenomenon, can take out successively annular metal sheet, directly change damaged part, saved greatly production cost, and equipment replacement is simple and fast comparatively, energy Effective Raise production efficiency, and energy-saving effect is comparatively obvious.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is top view of the present utility model;
Mark among the figure: 1, bell, 2, body of heater, 3, furnace lining, 3-1, induction coil, 3-2, refractory masses, 3-3, heater.
The specific embodiment
Specify in conjunction with the accompanying drawings and embodiments embodiment of the present utility model.
A kind of novel induction sintering furnace, mainly formed by bell 1, body of heater 2, furnace lining 3, it is characterized in that: the body outer wall of described furnace lining 3 is induction coil 3-1, middle for refractory masses 3-2, inwall are heater 3-3, described heater 3-3 is the tubular structure that annular metal sheet stacks together from bottom to up;
The heater 3-1 outside of sintering furnace is provided with protective device, and heater is exposed to cause energy waste to reduce, and prevents from occurring in the production process relevant burst accident;
The refractory masses 3-2 of furnace lining is existing refractory material such as refractory brick or fire-resistant cotton the composition, the number of plies of refractory material is pressed the need of production setting, any sintering furnace that production is set because of the varying number refractory masses, the protection domain that all belongs to this utility model that other mechanism of action is close;
The annular metal sheet of furnace lining heater is made by refractory metal material, as: tungsten, molybdenum etc.;
The diameter of the annular metal sheet of the heater 3-3 of sintering furnace furnace lining is increased to the top successively by the bottom, guarantee that namely heater has certain angle by the bottom to trend and the vertical direction at top, this set-up mode that certain angle of inclination arranged is conducive to the disassembling, assembling and replacing of base circle metallic plate, can effectively shorten the replacing time of compromised devices, enhance productivity; The increase degree of diameter is pressed the need of production setting, take the beneficial effect that can at utmost implement this utility model as best;
Be filled with oxidation zircon sand between the annular metal sheet of described heater 3-3 and the refractory masses 3-2, the existence of oxidation zircon sand, on the one hand can play insulation effect, can prevent to a certain extent that internal heat from distributing, keep the uniformity of temperature, atmosphere in the furnace lining, reduce energy consumption, on the other hand, when the expanded by heating phenomenon appearred in heater in the course of the work, oxidation zircon sand can also play certain cushioning effect, can slow down metal heated expansion institute damaged, prolong the service life of heater; Other material that is similar to zirconium sand is as what fill, and the mechanism of action is close, is considered as embodiment of the present utility model;
Heater 3-1 is connected with external power source.
