Description

[0001] The present invention relates to a flame spray device for suppressing flame and bubble generation in a melting furnace,

More particularly, the present invention relates to an anti-inflammatory agent spraying apparatus for suppressing flame and bubble formation in a melting furnace, and more particularly, to an anti- The present invention provides an anti-inflammatory agent spraying device for spraying compressed anti-inflammatory agent by using the anti-inflammatory agent, thereby preventing the use of an excessive anti-inflammatory agent due to uniform distribution of the anti-inflammatory agent and minimizing the amount of anti- And to an apparatus for injecting an anti-fogging agent for suppressing the generation of bubbles.

Generally, a melting furnace is a furnace manufactured for melting and melting a solid material at a melting point or higher. As a heating method, coke, coal gas, natural gas, heavy oil, coal or the like is used as fuel, Acrylic, and the like.

However, in the conventional melting furnace, bubbles are generated during melting, and the bubbles thus generated explode due to oxidation and combustion by the difference in pressure. In other words, the hot bubble tends to expand, and the dissolved substance acts only in the outward direction of the bubble, so that the dissolved substance is pushed by the bubble. Also, as the volume of the bubbles increases, the internal pressure decreases. At this time, when the internal pressure of the bubbles becomes lower than the pressure of the molten material, a bubble explosion occurs in which the dissolved substance penetrates into the bubbles and the bubbles are destroyed.

Such a bubble explosion causes a part of the dissolving material to bounce out from the melting furnace, thereby causing a safety accident that damages the periphery of the melting furnace, that is, the worker's injury or the apparatus, due to the high- have.

In order to solve this problem, a flux is often sprayed on the melting furnace to prevent bubble explosion. That is, the operator confirmed the bubble formation state in the melting furnace, and sprayed the anti-inflammatory agent on the above-mentioned melting furnace before the bubbles exploded due to oxidation and combustion, thereby suppressing the generation of bubbles in the above-mentioned melting furnace.

On the other hand, Mg alloy return scrap recycling technology contains impurities such as Fe, Ni, Cu, inclusions such as oxides and chlorides, which causes degradation of corrosion resistance and quality deterioration. In order to recycle high-quality Mg alloy recycled ingot, it is necessary to refine the process to remove these impurities and inclusions.

A Mg alloy melt processing techniques, a fluxless process using a shielding gas of KCI, NaCI, MnCI2, such as flux process, and SO _2, SF6 using a chloride-based flux, such as CaCI2. When the Mg molten metal is exposed to the atmosphere, an unstable oxide film is formed on the Mg molten metal surface and rapidly oxidized and burnt. Therefore, shielding gas such as flux or SO ₂ or SF 6 must be used for oxidation and burning prevention of the Mg molten metal . When a flux is added to the Mg molten metal, a protective film is formed on the Mg molten metal surface, which prevents the Mg molten metal from oxidizing and burning by blocking the reaction between the Mg molten metal and the atmosphere. In addition, even when a shielding gas such as SO ₂ or SF 6 is used, a stable protective film is formed on the surface of the Mg molten metal to prevent the Mg molten metal from being oxidized and burned.

In the flux process using chloride-based fluxes such as KCI, NaCI, and MnCl ₂ , insoluble chloride of MgCl ₂ is formed by the reaction between the molten magnesium and the chloride-based flux, and is immersed as a sludge at the bottom of the melting crucible after a certain period of time . Therefore, in the flux process, it is not easy to remove and treat sludge as well as Mg loss due to MgCl ₂ production due to the reaction between Mg molten salt and chloride flux. In addition, toxicity due to reaction with atmospheric moisture (H ₂ O) HCl gas is also generated, which causes environmental pollution. This problem occurs when a flux mainly composed of MnCl ₂ is used to remove Fe, which is an impurity element, in Mg molten metal. Therefore, there is a fluxless process in which Mn element is added in SF6 + CO ₂ shielding gas atmosphere. In this fluxless process, the addition of Mn without a chloride-based flux prevents the formation of MgCl ₂ and effectively removes impurities in the molten magnesium to produce a high-quality Mg ingot comparable to the quality of the primary ingot during Mg return scrap regeneration It is possible.

However, since the worker does not spread the anti-inflammatory agent widely in the process of spraying the anti-inflammatory agent, it is scattered and scattered in one place, so that the effect of inhibiting the occurrence of bubbles is not easily achieved.

In addition, the coagulant injected by the coagulant sprays the anti-inflammatory agent again, which causes the anti-inflammatory agent to be excessively added to the substance dissolved in the melting furnace, thereby lowering the purity of the dissolved substance. As a result, there is a problem in that the product competitiveness of the dissolving material is weakened.

In addition, in order for the operator to scatter the anti-inflammatory agent in the shovel in the melting furnace, the work is performed in the vicinity of the melting furnace so that the molten material contained in the melting furnace may be repelled by a mistake of the operator or the coagulated anti- There is a problem.
