Raw Materials for Aluminium Foundry

 Metallurgical flux coating material refers to the material which can separate metal from mineral by forming a low melting point slag layer while interacting with the rocks and harmful impurities in the orehe. According to the properties of flux, it can be divided into alkaline flux (such as limestone, dolomite, etc.), acid flux (such as quartz, metal ore with high silicone element, etc.), Neutral flux (bauxite, bauxite, etc.) and flux (such as fluorite, cryolite, etc.). It is generally required to have highly effective components, low harmful impurities. And ore strength and block degree should meet the requirements of the smelting process. Flux has the stable chemical composition, good selectivity, quick reaction, safe use, low corrosion and low price.

Characteristic and Function of Deslagging Flux for Aluminum Industry

图片
First, Functions and Characteristics Mainly used for aggregating the surface of the aluminium aqueous solution, making it easy to remove and ensuring the purity of the aluminium aqueous solution. It can also be used as a high-quality thermal insulation covering agent and slag-holding material, with a thick thermal insulation layer and excellent slag-holding performance, which can effectively insulate the air and prevent the secondary oxidation of the aluminium aqueous solution. The aluminum deslagging flux  industry does not burst, spreads quickly and evenly, and has strong slag gathering ability. It has the effective prevention of slag inclusion defects in castings, can improve the internal quality of castings, improve the yield of castings, reduce production costs; it has simple method of use, and can reduce labor intensity of workers, improve production efficiency. Second, advantages of using methods 1. Slag Removal and Slag Retaining: High-efficiency Deslagging Flu...

Notes for the Use of Alumina Foam Ceramic Filter

图片
  Alumina ceramic foam filter is a kind of porous material, which has a three-dimensional network structure and high porosity characteristics. Its function is to make the turbulent and churning molten metal become stable, uniform, and clean after passing through the foam ceramic honeycomb holes, thereby greatly reducing the casting waste rate caused by casting defects such as non-metallic inclusions and saving production costs.   Problems that should be paid attention to in the use of alumina ceramic foam filter:   1. In order to ensure the full filtration of the molten metal, the filter must have a certain pressure head for starting filtration to overcome the obstacle of surface tension. The pressure head size has a considerable effect on the start of the filter. Generally, it should be greater than 400mm. For large castings, the indenter should be correspondingly larger.   2. The overlapping part of the alumina ceramic foam filter and the mold should be sealed as f...

Aluminium Covering Flux

图片
  1. Product description Aluminum and aluminum alloy is easy to absorb and oxidize during melting, so it must be protected by spraying aluminium covering flux. When melting, it will form a physical barrier between molten aluminum and oxidation atmosphere in furnace, which will significantly reduce the formation of oxide inclusions in molten aluminum, which is conducive to improving casting quality and product application.   2. Product features It can form a dense protective layer, reduce the entrapment of gas, and reduce the metal loss caused by the oxidation of the liquid surface.It has the advantages of moderate melting point, good fluidity, and good coverage, in addition, it has less consumption, low cost, and low metal content.   Chemical composition and usage: the main components are chlorine salt, fluorine salt, and other salts and compounds. All components are properly treated to remove adsorbed water and crystal water and are screened to ensure uniform particle si...
