Molten metal anti-oxidation reducing agent, preparation method and application thereof

Abstract

The invention relates to a molten metal anti-oxidation reducing agent and a preparation method and application thereof. The molten metal anti-oxidation reducing agent comprises the following main compositions in portion by weight: 51.19 to 91.19 portions of nonylphenol polyoxyethylene ether, 3 to 15 portions of organic amine, 0.3 to 5 portions of phosphoric acid and 0.5 to 8 portions of phytic acid; the anti-oxidation reducing agent can further comprise essence in proper amount; and the molten metal anti-oxidation reducing agent is water-soluble oily liquid. The reducing agent has no flash point, does not splash when being added into molten metal and can automatically and rapidly diffuse; the molten metal anti-oxidation reducing agent is lighter than molten metal liquid and can overspreadthe whole flowing liquid level to isolate air and effectively prevent oxidation; contained active substances and organic or inorganic acid can disperse the inner gravitation of oxidized metal scruff,and actively scatter an inner structure of the oxidized metal scruff to reduce useful metal out; the reduction efficiency is 95 percent or so; cost performance is high; the residual scruff is little,soluble in water and convenient to clean; and the molten metal anti-oxidation reducing agent is convenient to maintain equipment.

Description

technical field [0001] The invention relates to an anti-oxidation reducing agent and its preparation method and application, in particular to a molten metal anti-oxidation reduction agent and its preparation method and application. 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 brou...

AI Technical Summary

Problems solved by technology

[0015] A: Diffusion is not fast enough and requires vigorous stirring

[0016] B: Viscosity is too high, it often adheres to the workpiece, causing product pollution and difficult to clean

[0017] C: Its viscous residue and molten metal mixture are attached to equipment parts in the molten metal flow cycle, resulting in blockage and blockage of equipment circulation channels, causing inconvenience to equipment maintenance

[0018] D: sediment, sticking to equipment parts, similar to resin-type hard substances, very difficult to clean

It is very inconvenient to maintain and clean the equipment. In the long run, it will definitely damage the equipment.
