Covering Flux-Csf2


C sf2 is an alkaline-based, sodium-free flux. It is a smoke-generating cover flux for all aluminum alloys, especially silicon-aluminum. It is used as an exothermic cover and drossing flux for aluminum-magnesium alloys melted in reverb furnaces. C SF2 will promote an improved separation of the dross and the molten aluminum and will not lead to sodium pick-up. C SF2 is a powerful, reactive flux to improve the modification of the aluminum.

Sodium free cover fluxes are used for melting hyper-eutectic aluminum-silicon alloys (alloys containing above 12.6% of Si). Hyper-eutectic alloys are modified by phosphorus, additions of which cause refining of the primary crystals of silicon. Sodium reduces the refining effect of phosphorus in such alloys.

Function and Application of the Granulated Refining Flux

图片
  The refining agent is white (slightly gray) powdery fine particles, the main components are chlorine salt and villiaumite, and  other compounds. After proper heating treatment and screening, the particle size is uniform, which is conducive to the refining tank entering into the lower layer of liquid aluminum evenly. Through physical and chemical changes, numerous small bubbles are formed in the liquid aluminum to fully contact with the liquid aluminum to separate the harmful gases in the liquid aluminum;At the same time, some substances contained in the granulated refining flux can strongly absorb and melt the oxides and suspended solids in the melt and adhere to the bubbles together. With the rising of the bubbles, they will be brought to the surface of liquid aluminum, so as to achieve the purpose of degassing and slag removal. It is environmentally friendly and economical, and can fully produce high value-added, high-tech aluminum alloy precision casting for aviation and ...

The Characteristics of Different Types of Sodium Hexafluoroaluminate

图片
  Sodium hexafluoroaluminate is also called cryolite, which sounds very good. It is a tasteless mineral of white, fine crystals, which has a greater solubility than natural cryolite. Easy to absorb water and become damp, it is mainly used as a cosolvent in aluminum electrolysis industry, a wear-resistant filler for rubber and grinding wheels, and an opalizer for glass and enamel, etc.   Sodium hexafluoroaluminate   can be divided into high molecular weight sodium hexafluoroaluminate and low molecular weight sodium hexafluoroaluminate according to its molecular ratio of sodium to aluminum. According to its physical properties, it can be divided into sandy cryolite, granular cryolite and powdered cryolite. The shapes, functions and requirements are also different. Next, SATA will explain it to everyone.   Ⅰ . The characteristics of sandy sodium hexafluoroaluminate   1. Its low melting point and fast melting speed can shorten the time to enter normal working state....
