Classification and Requirements of Fluxes for Aluminum Alloys

 Ⅰ. Classification of fluxes for aluminum alloys

There are many types of fluxes for aluminum alloys used in aluminum alloy smelting, which can be divided into two categories: covering agent (flux to prevent melt oxidation and burning and gettering) and refining agent (flux for degassing and removing inclusions). The covering agent and refining agent used in different aluminum alloys are different.

 

However, any fluxes for aluminum alloys used in the aluminum alloy melting process must meet the following conditions.

 

Ⅱ. The requirements of fluxes for aluminum alloys

1. The melting point should be lower than the melting temperature of aluminum alloy.

 

2. The specific gravity should be less than that of aluminum alloy.

 

3. Fluxes for aluminum alloys can absorb and dissolve the inclusions in the melt, and can discharge the gas from the melt.

 

4. It should not react chemically with metal and furnace lining. If it reacts with metal, it should only produce inert gas that is insoluble in metal, and fluxes for aluminum alloys should be insoluble in molten metal.

 

5. The hygroscopicity should be small, and the evaporation pressure should be low.

 

6. It should not contain or produce harmful impurities and gases.

 

7. It must have proper viscosity and fluidity.

 

JINZHOU SATA FUSED FLUXES AND NEW MATERIALS FACTORY has an independent flux formulation development department, which can provide different formulations according to customer needs to meet various needs of customers. The granular molten fluxes for aluminum alloys independently developed by our company is a new type of environmental protection type flux, there is no dust and smoke emission during use, conforms to international environmental protection standards, and improves the working environment of workers. The use of this flux is low and can save costs. Customers are welcome to come and buy.

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

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...
