Working Principle and Identification Method of Deslagging Agent

 1. What is deslagging agent?

 

Deslagging agent is the product of slag gathering and slag removing of iron cast steel, used for smelting and slag removing of cast steel, alloy steel, special steel and non-ferrous casting.

 

Deslagging agent is used for cleaning and slag gathering in the later stage of iron smelting. It is usually used in ladle, crucible furnace, reverberatory furnace and electric furnace, which can make the slag quickly accumulated, ensuring the cleaning of the molten liquid. Next, Jinzhou Sata Fused Fluxes and New Materials Factory will explicit the working principle of the deslagging agent.

 

After the metal finishes melting in the electric furnace, you sprinkle a little deslagging agent on the surface of the metal liquid for the preliminary slag removal and then sprinkle a thin layer to cover the surface of metal liquid because this can play a double role of heat preservation and slag gathering and finally remove slag before the metal liquid comes out of the furnace. Or you can sprinkle a little deslagging agent at the bottom of ladle when the molten steel is discharged.

 

2. How to the identify deslagging agent?

 

You can choose deslagging agent with good quality through such aspects as slag removal effect, usage and dosage. Deslagging agent neither causes dust nor contains toxic substances, thus it can improve the working environment and reduce the risk of occupational diseases. In addition, good slag removal agent into the ladle shall have some viscosity which can accumulate slag piles, as well as certain strength which is convenient to pick out the slag and save slag removal time. Good deslagging agent sprinkled on the surface of liquid metal can expand at high temperature to form a viscous active material with porous structure. It can adsorb the inclusions in the metal liquid and form a thin shell to collect and remove the slag. It is beneficial to purify molten steel and molten iron and improve the quality of casting.

Main Components of Deslagging Agent

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

  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...
