The present invention relates to a heat treatment furnace for heat-treating a metal workpiece or firing a ceramic material by arranging heater rods in a furnace with a field heater to partition a heat treatment region with a heater rod and simultaneously forming a material inlet at the bottom of the furnace. It relates to an up-loading heat treatment furnace having a heat treatment chamber partitioned by a heater rod to allow the material to be loaded up.

It is the flower of iron culture that various tools developed by humans are developed as a field of human civilization.

As a result, many parts having various properties are required, and only heat treatment technology is used to change the properties of iron according to this.

Recently, we have developed ceramics, which are called the dream material that will lead the 21st century in the era of iron culture, and are used for various purposes. These sinter films are also fired by heat treatment. It can be called a measure.

As such, the heat treatment furnace, which plays the most important role as the driving force of the basic industry, is classified into carburizing furnace, electric furnace, electrolytic furnace, and high frequency.

The present invention relates to an electric furnace in which the heat-treating heater rods are installed among the various heat-treating furnaces so as to heat-treat the high-temperature furnaces.

That is, the heater rod is usually installed on the inside of the furnace, which is the heat treatment chamber having the material inlet formed on the side, and the side wall or the bottom wall is inserted into the inside through the material inlet formed on the side, and then the power is applied to the heater rod. In addition, the heating rod installed on the bottom surface heats and matures the atmosphere inside the furnace to heat-treat the material loaded in the furnace.

However, the conventional heat treatment furnaces have heater rods installed only on the inner wall of the furnace, so if the heat treated materials are loaded at the same time and heat treated at the same time, the temperature inside the furnace is not uniformly distributed. As the temperature difference inside the accumulated material is increased, defects occur without uniform heat treatment, and it is a cause of shortening the life of the heater rods by operating the heater rods at a high temperature for a long time for the aging of the heat treatment atmosphere in the furnace.

Therefore, the heat treatment furnaces up to now have to heat the small amount continuously without heat-treating a large amount of material at a time, so the time required for the work is long, the electrical energy and thermal energy loss is large, and the incidence rate of defects was also high.

The present invention, after years of research to solve the above problems, developed a heat treatment furnace configured at the bottom of the material inlet to charge the material upward from the bottom to the top, to install more heater rods in the furnace in the cross-sectional field (田By arranging heater rods, heater rods are positioned between the partition ends between materials, so that the temperature inside the furnace becomes uniform, and evenly heats the components seated on the product seating base to reduce the incidence of defects and facilitate the work. Its purpose is to make it a part of.

In the present invention for achieving the above object in the construction of a heat treatment roll to heat or fire the product, forming a charging inlet for charging the material of the heat treatment chamber installed a plurality of heater rods in the heat-insulated interior, the lower body, A lifting table installed to elevate the lower side of the main body to stack the material to be heat-treated on the upper surface to raise and lower the pallet door to seal the entrance of the main body so that the material to be heat-treated is loaded upward from the lower side of the main body. It is configured, but the heat treatment chamber is configured to be partitioned into a field front (田) shape in the cross section by installing a plurality of heating rods to cross inside, front, rear, left and right.

This invention is described in more detail based on the accompanying drawings as follows.

As shown in FIG. 1 of the accompanying drawings, which is the overall configuration of the present invention, three layers are formed of the refractory boards 11 having different corresponding temperatures, and the insulated furnace body 10 is positioned downward at a constant height. To form a leg 20 of a constant height.

In addition, at least two guide holders 33 and elevating means 30 are provided inside the legs 20 so that the elevating table 35 stacks the materials on the upper surface thereof and the charging holes 13 of the robon body 10 are provided. ) Is configured to lift and lift the pallet door (50) configured to seal the guide rails, and guide rails (40) and (45) are formed on both sides of the lifting table (35) to coincide with the lowered position. It is comprised so that the pallet door 50 may be carried in and out easily.

Here, the elevating means 30 of the elevating table 35 for elevating the pallet door 50 may be configured by a lead screw 32 driven by a motor 31, but a cylinder may be used if necessary. Alternatively, the elevating table 35 may be elevated by using a chain.

In installing the heater rod 15 inside the main body 10 of the present invention configured as described above, the second embodiment of the present invention is shown in FIG. The heater rods 15 are installed in a plurality of layers as shown in the figure, but the array of these heater rods 15 is viewed in cross-section so that the heater rods 15 form a gardener as shown in FIG.

That is, one heater layer forms a field heater and forms a plurality of layers. At this time, the heater rods 15 should be installed in a range that does not invade the discharge area so as not to discharge each other.

Referring to the effects of the present invention made of the above configuration is as follows.

First, as shown in (a) of FIG. 4, the elevating table 35 is lowered to the lowermost end to match the guide rails 40 and 45 formed on both the left and right sides, and then the plane body inside the main body 10 is planar. Either side of the pallet door 50 on the guide rails 40 and 45 in which the to-be-heated material 60 to be heat-dissipated in four places is placed and placed so as not to interfere with the heater rod 15 installed in a field shape. To enter the lifting table 35.

At this time, the pallet door 50 has a roller 35a formed on the lower side thereof, and is fixed by entering the lifting table 35 on the guide rail 40.

Thus, when the pallet door 50 in which the to-be-heated object 60 is settled on the lifting table 35 is completed, the motor 31 is driven to rotate the lead screw 32 so that the lead screw 32 can be lifted by the rotation of the lead screw 32. Raised table 35 is raised as shown in (b) of FIG. 4, and the to-be-arranged object 60 placed on the upper surface of the pallet door 50 is placed inside the heat treatment chamber 12 of the main body 10. The pallet door 50 seals the charging hole 13 formed below the heat treatment chamber 12 of the main body 10 at the same time as entering the space between the heater rods 15 installed in the shape of.

As such, when the lifting table 35 is raised to the maximum and the pallet door 50 applies the heating power in a state where the charging hole 13 of the main body 10 is completely sealed, the heat treatment chamber 12 of the main body 10 is applied. Heat is generated in the heater rod 15 which is stacked and stacked in a field shape inside, thereby increasing the internal temperature of the heat treatment chamber 12 to heat-treat the toner 60 placed in the pallet door 50. At this time, the heated material 60 stacked in four places on the upper surface of the pallet door 50 and entered into the heat treatment chamber 12 is a heater rod 15 installed in a planar field heater inside the heat treatment chamber 12. The heat generated in the heat treatment chamber 12 is heat-treated as the temperature distribution inside the temperature rises uniformly, so that the heat treatment is uniformly heat-treated without fear that the heat treatment is wrong due to the internal temperature difference is fired to a high-quality material.

When the heat treatment operation is completed in the above state, the heating power is cut off and the motor 31 is driven to lower the elevating table 35 again. As shown in FIG. 4, the elevating table 35 is mounted on both guide rails 40. Pallets (50) heat-treated in accordance with the (45) to be heated 60 is carried out to the guide rail 40 and the pallet doors (50) waiting for the other guide rails 45 to the lifting table (35) It is good to carry in and raise, and to heat-process.

As such, when the heat treatment proceeds, the heat-treated material on the pallet door 50, which has already been heat treated and carried out to the guide rail 40, may be removed, and the next work may be prepared by stacking the heat-treated material 60 to be newly heat treated.

As described above, the present invention forms a charging inlet of the heat treatment chamber on the lower side and installs the heater rod in the shape of a field, so that more heater rods are installed in the heat treatment chamber in the same space so that the temperature inside the heat treatment chamber is more evenly distributed. There is almost no defect rate because it can mature the inner part of the furnace so that the temperature rise time is short, so the heat treatment time is shortened, which improves productivity and reduces the electricity consumption. This extends the economic benefits and creates a pair of stacked pallete piles, which can be brought in and taken out along the guide rails alternately to shorten the time to replace the workpieces, thereby reducing the overall work time. It is a novel invention which is very convenient in practical use.
