Description

Technical Field

[0001] The utility model relates to the field of high-temperature furnaces, in particular to a high-temperature furnace for high-temperature alloys. Background Art

[0002] A high temperature furnace is a device that can reach high temperature conditions and is usually used for high temperature processing and experiments. It is made of high temperature resistant materials and has the ability to maintain stable high temperatures.

[0003] After searching, the patent announcement number is CN206274222U, which discloses a high-temperature furnace. The high-temperature furnace includes a furnace body, which is provided with a cavity; a heating device, which is arranged in the cavity; a temperature detection device, which is arranged in the cavity; and a processor, which is connected to the temperature detection device and the heating device respectively. During the operation of the high-temperature furnace, the temperature detection device can measure the actual temperature of the high-temperature furnace, and control the switching state of the heating device by the actual temperature and the set temperature of the high-temperature furnace. On the one hand, it makes the operating temperature of the high-temperature furnace more accurate, and on the other hand, it avoids the high-temperature furnace itself. The temperature control fails, and the continuous temperature rise causes the high-temperature furnace to be scrapped or cause safety hazards such as fire, which plays a role in protecting the high-temperature furnace.

[0004] In the existing technology, although a certain high-temperature sintering effect of metal can be achieved during use, there is a defect: the existing high-temperature furnace lacks the problem of rapid heating and continuous low-energy high-temperature heating and insulation. In view of this, we propose a high-temperature furnace for high-temperature alloys to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problems existing in the background technology and to provide a high temperature furnace for high temperature alloys.

[0006] The technical solution of the utility model is: a high-temperature furnace for high-temperature alloys, comprising a base plate, a box body and a heating device, wherein the base plate is arranged at the bottom of the device; the box body is installed at the upper end of the base plate; the heating device is arranged at the bottom end inside the box body; wherein the heating device and the box body have a matching relationship.

[0007] When using a high-temperature furnace for high-temperature alloys in the present scheme, the box is mainly used for firing high-temperature alloys. The movable door is opened to place the alloy to be heated on the upper end of the placement plate, and then the heating device is controlled by the controller; the heating device is composed of an inductive collector and a heating resistor. First, they are started at the same time, but because the resistance heating is relatively slow, the inductive heater directly acts on the metal material to heat it. As time goes by, the temperature of the inert gas layer will increase with the operation of the heating resistor, and this temperature is not easy to dissipate under the support of the inert gas, so that after the inductive heater stops, the resistance heating can still ensure a stable high temperature effect. This device solves the problems of slow heating effect and poor insulation effect of the existing high-temperature furnace.

[0008] Preferably, a bracket is provided at the lower end of the bottom plate, and a base is provided at the lower end of the bracket. The bracket and the base can increase the stability of the device and reduce the propagation of noise to a certain extent.

[0009] Preferably, a controller is provided on the outer wall of one side of the box body, an exhaust pipe is provided at the upper end of the box body, an exhaust gas treatment device is provided at the end of the exhaust pipe, the controller is electrically connected to the inductive heater and the heating resistor, and is a device for controlling the two heating means. The gas generated by the heating will be discharged after evolving from the exhaust pipe.

[0010] Preferably, a heating chamber is provided inside the box body, and the heating chamber is fixed inside the box body through a mounting base. The heating device is provided at the lower end of the heating chamber, and a placement plate is provided inside the heating chamber. The heating chamber is used to heat the required metal material, and the placement plate material is relatively strong and will not react with most metals at high temperatures.

[0011] Preferably, the heating device comprises:

[0012] The induction heater is installed at the lower end of the box. Induction heating is a heating method that converts electrical energy into thermal energy using the principle of electromagnetic induction. First, by providing an AC power supply, a changing current is generated. This current usually has a higher frequency. The design includes an inductor coil, which is wound by an insulated wire. When the current passing through the inductor coil changes, a changing magnetic field will be generated around the coil. When a material (usually a metal) is placed near the inductor coil, the changing magnetic field will cause an induced current to be generated in the material. When the induced current passes through the material, Joule heat is generated according to the resistance of the material. This is because the current encounters resistance when passing through the conductor, and the electrical energy is converted into thermal energy. As the induced current continues to flow through the material, the material itself heats up. By reasonably designing the inductor coil and controlling the current parameters, the material can be heated quickly and evenly.

[0013] A mounting frame, mounted inside the box;

[0014] A mounting plate, fixedly mounted on the upper end of the mounting frame;

[0015] The heating resistors are installed in a linear array at the upper end of the mounting plate. Current passing through the resistors will generate heat, but this heat is initially low and takes a certain amount of time to reach the ideal value.

[0016] Preferably, a movable door is provided on the outer wall of one side of the box body, an observation glass is provided on one side of the movable door, a handle is provided at the lower end of the observation glass, the observation glass is made of high temperature resistant material, and the internal metal firing condition can be observed through the observation glass.

[0017] Preferably, the outermost layer of the box body is provided with a protective layer 1, a heat insulating layer is provided inside the protective layer 1, a protective layer 2 is provided inside the heat insulating layer, and an inert gas layer is provided inside the protective layer 2. The protective layer 1 and the protective layer 2 are made of metal materials with relatively high hardness. As the frame body of the box body, the heat insulating layer can effectively reduce the loss of heat, and the inert gas inside the inert gas layer has the effect of slowing down the spread of heat, which is very significant in the effects of thermal insulation and heat preservation.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] The utility model can utilize the induction heating and the resistance heating to jointly heat the metal, can heat at a high speed in a short time and continuously heat the metal, and can reduce the loss of a large amount of electric energy.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The heating device 300 is arranged at the bottom of the box 200. The heating device 300 is composed of an inductive heat collector and a heating resistor 304. First, they are started at the same time. However, since the resistance heating is relatively slow, the inductive heater 301 directly acts on the metal material to heat it. As time goes by, the temperature of the inert gas layer 210 will increase with the operation of the heating resistor 304, and this temperature is not easy to disperse under the support of the inert gas, so that after the inductive heater 301 stops, the resistance heating can still ensure a stable high temperature effect.

[0042] The inductive heater 301 is installed at the lower end of the box 200. Inductive heating is a heating method that converts electrical energy into thermal energy using the principle of electromagnetic induction. First, an alternating current is provided to generate a variable current, which usually has a higher frequency. The design includes an inductive coil, which is wound by an insulated wire. When the current passing through the inductive coil changes, a variable magnetic field will be generated around the coil. When a material (usually a metal) is placed near the inductive coil, the variable magnetic field will cause an induced current to be generated in the material. When the induced current passes through the material, Joule heat is generated according to the resistance of the material. This is because the current encounters resistance when passing through the conductor, and the electrical energy is converted into thermal energy. As the induced current continues to flow through the material, the material itself heats up.
