Abstract
The invention discloses a flange for medium frequency induction furnaces, and solves the problems of low equipment production efficiency, high maintenance cost and increasing waste generation caused by proneness to short circuit during use of the existing flange. The flange comprises a flange body. Four through holes are symmetrically formed in the flange body, the same side of each through hole is connected with an insulation tube matched with the same in size, an insulation rubber layer is arranged at the joint of each insulation tube and the corresponding through hole, and the inside of the tube wall of each insulation tube, spaced from one end of each insulation rubber layer, is provided with an insulation glass ribbon. By the flange, water vapor is effectively prevented from being condensed in engine electrodes at a lower temperature, the short circuit caused by moisture and waterflow between the engine electrodes and a furnace body is avoided, operation rate is improved by more than 30%, RMB fifty thousand Yuan is saved from maintenance cost of each medium frequency induction furnace, and waste defective goods are reduced by 10%.
Description
Technical field
The invention belongs to the tungsten technical field of processing equipment, relate to a kind of sintering equipment, be specifically related to a kind of ring flange for the Medium frequency induction sintering furnace.
Background technology
When the tungsten pressed compact, need to use the Medium frequency induction sintering furnace, sintering furnace all can use ring flange usually, and the effect of ring flange on intermediate frequency furnace is mainly to make four electrodes of the engine with 700 volts of voltage of intermediate frequency insulated from each other, and insulate with body of heater.Another effect is to seal body of heater by insulating flange plate, does not allow the hydrogen in body of heater overflow.
Existing Medium frequency induction sintering furnace is under hydrogen shield atmosphere during sintering tungsten pressed compact material; because the material moisture of being with itself will become steam; add in sintering process; oxygen in hydrogen and tungsten and molybdenum material reacts; generate water; and then evaporation becomes water vapour, in furnace temperature, reaches 1200 ℃ of left and right, and it is maximum that the content of steam reaches.Intermediate frequency furnace is connected with induction coil with the engine electrode of cooling water, steam under high temperature just condenses into the globule at the lower engine electrode place of temperature, and flow to body of heater along the insulating flange plate inner surface, under the effect of 700 volts of voltages, the mutual conducting of engine electrode and body of heater, form short circuit, and under the effect of short circuit current, insulating flange plate is burnt to carbonization, and the damage of forming device fault and material, cause that production efficiency of equipment is low, maintenance cost is large, waste material produces many problems.
Summary of the invention
The object of the present invention is to provide a kind of ring flange for the Medium frequency induction sintering furnace, solved in existing ring flange use procedure that the production efficiency of equipment that causes due to easy short circuit is low, maintenance cost large, waste material produces many problems.
The technical solution adopted in the present invention is: a kind of ring flange for the Medium frequency induction sintering furnace, comprise the flange disk body, on the flange disk body, be symmetrically arranged with 4 through holes, the same side of each through hole is connected with respectively the insulation tube that adapts with clear size of opening, each insulation tube and through hole joint are provided with the insulation glue-line, and the tube wall inboard of the end away from the insulation glue-line of each insulation tube is provided with the insulating glass silk ribbon.
Characteristics of the present invention also are,
The internal diameter of insulation tube is than the large 10～20cm in the aperture of through hole.
Insulation tube is coaxial with through hole.
The invention has the beneficial effects as follows: use insulating flange plate of the present invention, effectively prevented steam condensing at the lower engine electrode place of temperature, avoided through moisture and current cause the short circuit between engine electrode and body of heater, improve operation rate more than 30%, annual every Medium frequency induction sintering furnace is saved 50,000 yuan of maintenance costs, and reduces by 10% waster.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of ring flange for the Medium frequency induction sintering furnace of the present invention;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is enclosed within the use state diagram on the engine electrode by ring flange of the present invention.
In figure, 1. flange disk body, 2. through hole, 3. insulation tube, 4. insulation glue-line, 5. insulating glass silk ribbon, 6. engine electrode.
The specific embodiment
The present invention is described in detail below in conjunction with the specific embodiment and accompanying drawing.
The invention provides a kind of ring flange for the Medium frequency induction sintering furnace, as depicted in figs. 1 and 2, comprise flange disk body 1, on flange disk body 1, be symmetrically arranged with 4 through holes 2, the same side of each through hole 2 is connected with respectively the insulation tube 3 that adapts with through hole 2 sizes, each insulation tube 3 is provided with insulation glue-line 4 with through hole 2 joints, and the tube wall inboard of the end away from insulation glue-line 4 of each insulation tube 3 is provided with insulating glass silk ribbon 5.
The internal diameter of insulation tube 3 is than the large 10～20cm in the aperture of through hole 2.
Will be as shown in Figure 3 during installation, 4 through holes 2 of flange disk body 1 are inserted in respectively on 4 engine electrodes 6 of Medium frequency induction sintering furnace, with the insulating glass silk ribbon 5 of the open end of insulation tube 3, will on the engine electrode, be wound around, until there is no space between insulation tube 3 and engine electrode 6, this section engine electrode that is in insulation tube 3 inside is that temperature is than lower part.
During work, when high-temperature water vapor flows in stove, engine electrode part temperature is lower by insulation glue-line 4, insulation tube 3 and insulating glass silk ribbon 5 is airtight, water vapour does not reach the engine electrode 6 that temperature is lower, can only touch insulation glue-line 4, insulation tube 3 and insulating glass silk ribbon 5, therefore water vapour can not heat release condense into water droplet, in can only being with slowly and coming out of the stove by hydrogen, and then also just avoided the problem of short circuit between engine electrode and body of heater, reduce maintenance frequency, reduced the generation rate of waster.
By the way, a kind of ring flange for the Medium frequency induction sintering furnace of the present invention, solved in existing ring flange use procedure that the production efficiency of equipment that causes due to easy short circuit is low, maintenance cost large, waste material produces many problems.Use insulating flange plate of the present invention, effectively prevented steam condensing at the lower engine electrode place of temperature, avoided through moisture and current cause the short circuit between engine electrode and body of heater, improve operation rate more than 30%, annual every Medium frequency induction sintering furnace is saved 50,000 yuan of maintenance costs, and reduces by 10% waster.
