Degassing-Flux


General description and function of Degassing-Flux

（In order to increase the mechanical properties of the aluminum alloys, it is necessary to reduce the pinhole porosity arising out of hydrogen presence, as well as increase the nucleation sites for better microstructure. ）

Presence of hydrogen in solidification leads to pinhole defect, excessive porosity, lower metal density, and reduced mechanical properties. Degassing fluxes composed of chlorine and fluorine containing salts are used for degassing of aluminum alloy shaped in tablets form.

Degassing products remove hydrogen dissolved in the molten alloy. degassing flux can also remove non-metallic impurities (oxides, carbides, etc.) from the metal, creating a better-finished product.


Advantage of Degassing-Flux

1. Degassing flux release nitrogen gas, which has a very positive effect of removal of hydrogen entrapped during melting operations and for oxides, micro-oxides and impurities reduction

2. Has a combined effect of physical and chemical nature

3. Have different compositions to suitable for Al-Mg alloys with a content of Magnesium above 3% and below 3% as well and suitable for al-mg alloy will not disturb sodium or strontium modification effect.

Main Components of Deslagging Agent

图片
The main components of deslagging agent are potassium, chlorine and fluorine. Among them, JKCZ-1 and JKCZ-2 all contain sodium, while JKCZ-3 does not contain sodium. The deslagging agent  produced by our company alleviates the disadvantageous factors of iron oxide to melt lime. The slag remover is adopting pre-melting process of calcium oxide, alumina and iron oxide and by pressing ball process. Because of the pre-melting process, calcium oxide is melted in advance, and calcium ferrite and calcium aluminate are formed in advance with iron oxide and alumina, which can reduce the heat needed for converter melting and shorten the melting time. The composite minerals formed by ferric oxide and alumina and calcium oxide have low melting point and fast melting speed, which can promote the quick melting of lime in converter. The alumina content of this product is different from that of pre-melting refining agent, and its price is relatively low. The product can reduce the use of conv...

Degassing Flux  (SATA-PF-350) General Description of Degassing Flux (SATA-PF-350) Practice has proved that the hydrogen is the main cause of the pores in the aluminium alloy, the pores not only reduce the actual cross-sectional area of the casting, but also the source of the crack, so it is important part that removing the hydrogen during the smelting process. SATA-degassing flux   also name aluminum degassing flux   is   a kind of traditional high efficiency degassing flux for aluminium and its alloys, it used for removing hydrogen and oxides from the aluminium melting. Application of Degassing Flux (SATA-PF-350) Plunge suitable quantity flux to the bottom (100mm from the bottom is better) of the melt, evenly and slowly remove the lunch, make the flux fully react with aluminium molten, stand or stir the molten for 10-15 min, the hydrogen and oxide will be taken out of aluminium molten. Advantage of Degassing Flux (SATA-PF-350) Easy operation, There ...

Covering Flux Characteristics You Don't Know

图片
  The covering flux is a covering material that can extend the solidification time of the molten metal in the riser and cover the surface of the molten metal in the riser during casting production. There are two types of covering fluxes: thermal insulation covering fluxes and heat-generating covering fluxes.  We provide refining flux , alumina ceramic foam filter , grain refiner for aluminium , magnesium flux , electrode flux material an d s o on.   The characteristics of the covering flux are as follows:   1. The thermal insulation covering flux is made of low thermal conductivity materials, such as expanded perlite, expanded graphite, etc.   2. In addition to the low thermal conductivity material, the heating covering flux is added with a certain proportion of heating materials. Under the heat of the molten metal, the oxidant provides oxygen to oxidize the reducing agent and generates heat, thereby prolonging the solidification time of the molten metal in...
