Description

Organic container for induction {Cooking Vessel Made Of Brass For Induction Range and manufacturing method thereof}

The present invention relates to an organic container for induction, and more particularly, by thermally spraying a material powder that is magnetized to a brass container or a brass-coated container, an eddy current is generated in the container by the magnetic field of the induction range to enable heat generation. It relates to organic containers.

Tableware made with Bangjja is called 'Bangjja yugi' or 'brass bowl'.

If you look at the process of making products using traditional bangja, heat is applied in an alloy of copper and tin, and then quenched with a hammer to make a plate with an even texture, and then beat the plate with a hammer to make dishes or musical instruments, etc. make a variety of products.

In other words, Bangjja Yugi is made by a forging method in which copper and tin are precisely alloyed in a ratio of 78:22 and the molten metal ingot is heated and hammered.

The Bangjja manufacturing method is a hot forging method, and it goes through a high-level work that requires several people to mash at the same time.

Bangjja Yugi produced in this way is most suitable for tableware because it sterilizes and disinfects itself. Aesthetically, the seashell marks (hammer marks) remain, and the more it is used, the more glossy it remains, and the taste of handicrafts remains.

The range of use of Bangjja-yugi as described above is limited because magnetization does not occur by magnets.

In other words, it is a process in which the popularization of induction stoves, which replace gas stoves, is rapidly taking place in line with changes in kitchens in recent years.

The induction stove generates magnetic force by flowing current through the coil inside to generate eddy current at the bottom of the pot containing magnetic components. For the container, you must use a container dedicated to the induction range that contains a magnetic material.

However, in the case of Bangjja Yugi, since it is not a material that reacts to magnetic components, it cannot be used in an induction stove, so there is a limitation in the usability of Bangjja Yugi.

Typically, the induction vessel includes an electrically conductive material, and the material includes steel, iron, nickel, or various types of alloys. Induction containers are generally used by attaching a magnetic material to the bottom of a general container (usually the part in contact with the grill of the stove) according to the principle of operation of the induction stove.

Since the induction stove itself is not heated when in use, only the cookware is heated, so it has advantages such as high safety and excellent economic feasibility and prevention of burn risk compared to heating appliances such as a gas stove using a conventional indirect heating method.

Conventional induction containers have a problem in that cookware in which iron is sprayed on aluminum when manufacturing the induction container has poor heating efficiency, and iron is dropped during cleaning of cookware.

In addition, the induction container can be manufactured using stainless and aluminum clad materials, and such an induction container can only form a drawing product with a simple shape. There is a disadvantage that the product cannot be diversified because it cannot be thickened and complex shapes cannot be formed.

By joining, an eddy current is generated in the container by the magnetic field of the induction cooker to generate heat.

The manufacturing process will be described with a detailed description of each embodiment as follows.

In the first embodiment and the third embodiment, the material powder is sprayed into a container made of a mixture of copper and tin, stainless equipment, or a container made of an aluminum material, and an eddy current is generated in the container by the magnetic field of the induction stove to generate heat. .

First, the first embodiment includes a container made of brass (hereinafter, referred to as 'brass') which is a mixture of copper and tin.

The container is manufactured by heating and rolling a plate-shaped base material and then molding it through a mold.

That is, the molten material of tin and copper is processed into a circular plate-shaped base material.

To this end, the molten material is manufactured into a circular plate-shaped base material by a casting method, and then the plate-shaped base material is heated to a temperature of 300 to 400 °C.

Thereafter, the plate-shaped base material is passed through a rolling device in which a pair of rollers are installed facing each other and processed to a uniform thickness, while at the same time, oxides or impurities penetrating into the pores of the plate-shaped base material are extracted in gaseous form to reduce the oxidation of the plate-shaped base material. .

Next, press working through a mold using properties such as plasticity, malleability, and fluidity of the plate-like base material in a heated state.

Through this, it is manufactured in the form of a container with an open top made of a brass material.

The container manufactured as described above is thermally heated by generating an eddy current in the container by the magnetic field of the induction range by thermally spraying a material powder magnetized by magnetic force on a part or all of the surface.

The thermal spraying process of the material powder is as follows.

First, the base material is preheated to a temperature lower than the melting point of the container to activate the surface of the container and remove moisture.

The melting point of brass is 900~950℃, and the preheating temperature is 500~600℃.

After preheating, a material powder made of metal powder that can be magnetized by magnetic force such as iron powder is sprayed on the surface of the container, and then cooled so that the material powder can be coated on the surface of the container.

Here, the material powder is a material that is strongly magnetized in the magnetic field in a magnetic field as a ferromagnetism and retains its magnetism even when the magnetic field is removed. can be applied.

And, the thermal spraying process refers to colliding with the surface of the container so that the crushed material powder particles are coagulated and deposited on the surface of the container to form a film.

In other words, it is manufactured into a container by pressing through a stainless or aluminum material that is easy to produce in the form of a low-cost bowl.

Next, an organic coating layer that gives the physical characteristics and texture of brass to the surface of the container and a material powder that enables magnetization by magnetic force are coated on the surface of the container so as to be distinguished from each other.

For example, the material powder is coated on the bottom surface of the container through which the flame is transmitted directly, and the organic coating layer is coated on the other surface of the container.

In this way, the film position of the material powder and the organic coating layer to be filmed on the surface of the container can be selected by selecting various film positions according to the purpose of use of the container.

The heating temperature is 300-400 °C for the plate-like base material made of stainless steel, and 200-250 °C for the plate-shaped base material made of aluminum.

The above heating temperature is a temperature range for the easiness of optimal plastic deformation and removal of oxidizing materials based on the melting point of the plate-shaped base material.

Thereafter, the plate-shaped base material is passed through a rolling device in which a pair of rollers are installed facing each other and processed to a uniform thickness, while at the same time, oxides or impurities penetrating into the pores of the plate-shaped base material are extracted in gaseous form to reduce the oxidation of the plate-shaped base material. .

And, the thermal spraying process refers to colliding with the surface of the container so that the broken material powder particles are coagulated and deposited on the surface of the container to form a film.

After that, in order to stabilize the stable film state of the thermally sprayed material powder, the stainless steel container is heated to 700~800℃, and the aluminum container is heated to 400~450℃ to generate thermal stress inside the container. Removal and impurities contained in the material powder are removed by vaporizing it in a gaseous state.

In addition, the coating method of the organic coating layer applied in the third embodiment is as follows.

First, the organic coating layer is a mixture of organic powder made of copper and tin, an organic mixture containing an acid and a silicon compound, and a coating solution of PTFE dispersion, water, aromatic hydrocarbons, triethylamine, oleic acid, and a surfactant, applied to the surface of the container and then heat treated to coat the surface of the selected container.
