Description

The heat process furnace of the table rotation style}

The present invention relates to a table rotary heat treatment kiln for precision casting and forming parts of industrial machinery, medical equipment, etc. using a cupping table.

In the present invention, the term " tang ball table " refers to a hollow cast body having the same shape as the specific product outline to be cast in forming a specific product in the industrial art. I speak.

On the other hand, the method of forming the above-mentioned "tang ball stage" forms a model product having the same shape and shape as the specific product to be cast-formed in the first step, and the surface of the model product in the second step. In the third step, the sand and ceramic material is repeatedly coated to dry the product having a constant thickness, and in the fourth step, the sand and ceramic material are coated and dried. In the fifth step, the model product is dissolved and removed by applying room temperature to the dry sand and ceramic coating material having a specific shape in the process. In the fifth process, the model product is dissolved and the inside is hollow (that is, a part of watermelon). If you scrape the contents and scrape off the contents are formed like a watermelon peel) state is formed in the "bathing table" is formed.

On the other hand, to explain in more detail the formation method of the model product and the molten metal, first, the model product is made in a semi-melted state by applying a room temperature to the solid wax (wax), which is initially hard, that is, a well-known soap-like state. A model product of a specific shape is formed, and the formed model product is cooled, and then the surface of the model product is repeatedly subjected to several times by coating and drying the selected ceramics and the ceramic material processed to the same level as the sand. Apply thickly.

Subsequently, the coated model product is dried on the sand and ceramic material coated on the outer surface, and after drying, the solid wax, which is a model product, is dissolved by applying heat at room temperature of 58 ° C. to 60 ° C. Let it flow

The sand and ceramic materials in which the wax is dissolved and flowed out are all formed of a cupping table in which the inside thereof remains in a hollow state formed in the same way as the model product. It is a disposable product which is heat-treated at the above-mentioned high temperature, and the molten metal is poured, and it casts and forms the desired product, and breaks (breaks).

On the other hand, the rotary kiln of the present invention, after forming the bottom surface of the concrete structure or forming a circular support plate (beam or angle is easy and steel plate is also possible), the support plate having a certain height on the upper surface of the support plate To form a plurality of rolling rollers in a circular direction at regular intervals, and to form a circular cylinder with a hollow inside at the center, and also to the upper surface of the roller roller in a ring shape on the outer circumferential surface along the circle After that, the chain is connected and a disk-shaped rotary table is rotated by a geared motor. On the other hand, a circular wall is formed around the circle of the rotary table, and burners are installed in four directions of the wall and discharged through each other. The furnace is installed in three directions, and a ceiling having an exhaust pipe through which the discharge passage is connected is formed.

In addition, according to the present invention, as the table of the heat treatment kiln is rotated, a vortex phenomenon occurs in the room, and thus the combustion heat of the burner generated inside the kiln is naturally circulated to maintain a constant temperature of the upper and lower portions of the kiln. It will be able to help the heat treatment operation of the pool table.

On the other hand, it is well known that the heat treatment kiln currently used in the art is constructed of a fixed structure in which an entrance and an exhaust port are formed in the same structure as a well-known ceramic kiln, and a burner is installed. Energy is known to use low-cost fuel or light oil due to environmental pollution. However, in the case of very small kilns, electric heating devices are used, but all of them have many problems. Although it is true, in the present invention, a description will be omitted for the conventional heat treatment kiln for convenience, and the heat treatment kiln which is most used will be described.

Industrial heat treatment kiln most used in the technical field is about 2 ~ 2.5m in height, about 3 ~ 5m in diameter, and the fuel is diesel or quaternary oil (aka bunker seed oil) Use

The reason for using the light oil or bunker seed oil of the fourth class is selected in terms of thermal power and cost reduction, and the temperature inside the kiln at this time is different depending on the target of the heat-treated product, but in most cases, the temperature of 1,000 ° C or higher and 1,260 ° C is maintained. In addition, when putting or removing the heat-treated material (herein referred to as the "steam table") into the kiln, the worker normally places a sprinkler on the end of the metal pipe (pole end) which is made of long-sleeved fire protection suit and gloves. Carefully put it in or out of the kiln by walking, but no matter how good the quality of the fire suit and gloves worn by the worker during the above work, the temperature inside the kiln will be irradiated with a high temperature of at least 1,000 ° C. (Iii) it cannot endure long enough and its heat can only be transmitted to the workers. Is a very poor environment and condition, but because there is no countermeasure, the work is carried out with pain, and the grievance of these workers is larger when the size of the heat treatment kiln is larger. In this case, the display of the cupboard is far away from the entrance, and the display of the cupboard far away from the entrance is very painful. Another is that lifting a long iron rod that is at least three meters or more doesn't end up as a heavy one, but rather a heavy fever on the end of the iron rod, with one hand grasping one end, This is because the heat treatment kiln to be irradiated must be displayed deeply.

In general, there is no big problem when placing a ping pong stand at the entrance of the kiln because the worker cannot try to do the work away from the kiln because of the structure of the kiln. High heat is irradiated more because the heat must be closer to the heat treatment kiln, while the operator tries to move a little further away from the heat treatment kiln, eventually leading to a greater center of gravity between the worker and the pour basin. to be.

The present invention comprises a rotary table corresponding to the bottom surface of the heat treatment kiln, at a constant height from the ground, the rotating table is configured to be separated from the wall surface so that it can rotate by the power of the motor, Provides a table rotary heat treatment kiln that allows the operator to carry out work at the furthest distance from the kiln's heat when loading or unloading it.

It is another object of the present invention to provide the effect of increasing the internal temperature of the kiln by rotating the circulation heat of combustion inside the kiln automatically as the table rotates. LPG or LNG gas) can be used as an alternative to cost reduction and effectively solve environmental problems.
