Molten metal oxidation resistance reducing agent

Abstract

The invention relates to metal melting antioxidative reducing agent, wherein the main component and the content of weight by parts comprises nonyl phenol polyoxyethylene thioether 51.19-91.19 parts, cyclohexylamine hydrobromate 5-20 parts, diphenyl guanidine hydrobromate 3-15 parts, phosphoric acid 0.3-5 parts, and phytic acid 0.5-8 parts, and further contains right amount of perfume compounds. The invention is oil liquid, since the invention is added with surface-active substance, when two liquids contact, relative / infrequent two-way molecular linkage can be generated, the surface tension of high-melting metal can be reduced, and simultaneously antioxidative reducing liquid is promoted to automatically diffuse rapidly. The invention is lighter than metal melting liquid, which can bespread whole flowing liquid and isolate air, and effectively prevent oxidation, while active substance and organic or inorganic acid which are contained in the invention can disperse inner gravity of oxygenized metal dross, take the initiative to break the inner structure of oxygenized metal dross, deacidize available metal, and deacidizing efficiency is about 95%, and the invention has high performance price ratio, less residual dross, cleanness and convenience, which is convenient for equipment maintenance.

Description

technical field

[0001] The invention relates to an anti-oxidation and reduction agent, in particular to an anti-oxidation and reduction agent for molten metal. Background technique

[0002] In industrial production, it often involves the process of melting a metal or alloy to combine or adhere to another metal. Since most metals will oxidize when in contact with oxygen, such as iron rusting is the most common example of oxidation. In a high-temperature environment, especially in a molten state, the oxidation of the metal (or alloy) will be more severe, and a layer of oxide will soon be formed, and the more it gathers. In the process of adhesion and bonding of molten metal and other metals, the molten metal must be continuously flowed and circulated, which will intensify the oxidation rate on the one hand, and on the other hand mean that the oxides on the surface and a small amount of oxygen will be brought to the liquid surface Below, the liquid interior. Oxidation then a...
