があつた。Problems to be Solved by the Invention: In conventional precision casting method, die casting method, hot casting method, casting light alloy casting method, extrusion method, ingot casting method, continuous casting method of various metals, various powder graphites, vegetable oils as lubricating substances. ,
Mineral oil, silicone oil and the like are used alone or as a mixture, but oxidation of the hot metal surface cannot be completely avoided. When oxidation of the metal surface occurs, skin,
Scratches and the like occur. Conventionally, in order to prevent such oxidation of the metal surface, an inert gas such as argon nitrogen has been blown onto the high-temperature metal surface. However, blowing the inert gas has a disadvantage that the molten metal itself is cooled, and that the inert gas itself is expensive.

Tetrafluoroethylene resin (hereinafter referred to as PTFE) or PTFE
And boron nitride (hereinafter referred to as NB) in an amount of 1 to 20 with respect to the total weight.
It was discovered that the lubricant obtained by adding wt% has a function of preventing metal oxidation as well as a function of lubrication.

充分である。NB is superior in heat resistance, high temperature lubrication, high temperature, lubrication with molten steel surface, excellent in releasability, PTFE is superior in heat resistance, lubrication, high releasability, high temperature, is produced by gasification in contact with molten steel surface Prevents the generation of scum due to the strong ion reduction reaction of carbon tetrafluoride (CF 4 ), prevents the primary surface oxidation that occurs during the formation of solidified shells, and maintains the non-oxidizing atmosphere in the mold and hood, so that high temperature and molten metal Actively prevents surface oxidation of interface slabs. That is, by combining this metallurgical mechanism with the lubricating base oil, a mold is formed by a normal Euler mechanism,
By continuously supplying lubricating lubricating oil to the caster, a high-temperature active lubricant is achieved, and high-quality precision cast slabs can be mass-produced. The effect is remarkable and unrivaled.
The general thermal decomposition is an endothermic reaction (nitrogen sealing), whereas the high-temperature active lubricant (PTFE) has an exothermic reaction (11,000cal /
g) has a heat retaining effect, and can cover casting obstacles caused by temperature drop such as stagnate of the stream and discontinuity. Safety As for this high temperature active lubricant, natural ventilation is sufficient because the PTFE content is less than 10wt% at maximum and a small amount of HF is adsorbed and diffused into oil fume (oil mist).

る。The lubricant of the present invention can be used as a lubricant for high-temperature metal working such as casting of iron, iron alloy, stainless steel, aluminum, aluminum alloy, copper and the like. Particularly, in iron casting and the like, lubrication may not be achieved by PTFE alone. In this case, NB is added. The use of a lubricating oil to which NB is added improves the releasability of the metal, so that NB can be used as one of the components of the lubricant in processing such as casting of any metal.

The surface is roughened due to oxidized composite.The surface is blown by subcutaneous blowholes. In addition, the life rotation rate is deteriorated because the mold release is not good. The present invention provides better lubrication, mold release, non-oxidizing agent, composition examples 1, 2, 6, and 8 under the same conditions as in the prior art. In a non-oxidized state. Particularly troublesome, the corners were smooth and had a metallic luster. In particular, Example 2 was entirely good. The yield was the same overall and improved about 3%.

As a result, the aluminum surface of the mold is degreased and washed quickly. As for the trouble and work environment in which the oxide film surface treatment must be performed, graphite scatters on the graphite powder residual carbon powder, and the environment deteriorates. Yield is poor because it does not prevent oxidation. The present invention provides better lubrication, mold release, and non-oxidant composition examples 3, 4 and 7. Automatic spray application to the mold under the same conditions as in the past, automatic pouring, cooling after cooling, and observation of the state of the mold surface. Even in the case of (1), the metal surface is smooth without any roughening, is aluminum metal luster and is non-oxidizing, and there is no non-adherence of the residue. Therefore, the cleaning can be omitted and the non-oxidizing method can be used continuously, thereby improving the yield. The work environment contributes to good environmental improvement because no black powder is produced.

全面無手入となりコスト低減に寄与する。Practical example 3 Conventionally, oil-soluble graphite and silicone oil were used as molds, lubrication, and mold release agents in the mold casting method. The surface of the mold must be periodically cleaned to prevent surface adhesion. Oxidation of the casting surface and subsequent coating of the residue may require cleaning. The same applies to silicone oil. According to the present invention, composition examples 3, 4, 7, and 8 were automatically applied by spraying to a mold, automatically poured, and the state of oxidation of the inner surface of the casting mold after cooling and the residue were observed.
In all cases of 4, 7, and 8, the surface skin was smooth without oxidation and had a metallic luster. For residues, 4 and 7 were not noticeable to the naked eye. In composition 8, a small amount of residue was observed, but the degree was small enough to be sufficient for autonomy. Lubrication and mold release are good, and the yield is improved by non-oxidation. Since there is no residue adhesion, the step of cleaning the casting mold can be omitted, and the entire surface is free of maintenance, which contributes to cost reduction.

りコント低減に寄与する。Practical example 4 Swedish horizontal shear shaping method (pulling method) Conventionally, copper, copper alloy, brass automatic pouring, etc., when lubrication and mold release agent are not used at the interface inside the round graphite mold, when the mold is pulled out The surface of the mold was abraded due to severe mold interface wear and the copper surface was oxidized. The present invention sprays composition examples 1, 2, and 6 from upper and lower two places for lubrication, mold release, and oxidation prevention. As a result of observing the state of the copper surface, it was found that the copper metal was smooth and had a metallic luster. Yield has improved significantly since it is not oxidized. Graphite molds are expensive and contribute to a reduction in control because the life rotation rate is improved due to reduced wear.
