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 converte

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 are two options. On

Drossing-Off Flux

图片
General Description And Function of Drossing-Off Flux Drossing-off flux is used to absorb oxides and non-metallic material, cleansing the metal and forming a good metal-free dross which can easily be removed.  Drossing-off fluxes agglomerate the oxides allowing easy removal from the surface of the melt. They are used to remove the dross with the minimum metal loss  Advantages of Drossing-Off Flux 1. Being exothermic fluxes, it can ensure that liquid aluminum trapped in the dross layer is returned to the melt. Produce dry powdery dross.  2. Provide further decrease of the flux melting point and improve its cleaning ability. Due to the high wetting capacity of fluoride compounds: it has a good effect of contributes to oxide – metal separation.  3. It helps recover metal from this slag layer , improving the yield of the process.
