EDX9000B plus is used for rapid analysis and determination of powder components of refining agent
Refining agent is white powder or granular flux, which is prepared by a variety of inorganic salts after drying and mixing according to a certain proportion. It is mainly used to remove the hydrogen and floating oxidation slag inside the liquid aluminum. Its main component element is aluminum element.
The refining agent is suitable for commonly used aluminum alloys (alloys with high magnesium content and aluminum-magnesium alloys cannot be used), and pure aluminum smelting, degassing refining and slag removal. In use, the refining agent has the following characteristics:
1, deoxidation. The product contains 8%-12% metal aluminum, when the converter steel use, oxygen can be removed to 40ppm below, the effect is good.
2. Promote desulphurization. The product contains a reasonable amount of AI20 after special processing, in a critical state, with strong activity is easy to combine with CaO, forming calcium aluminate slag system, the slag system has a high sulfur capacity, in addition due to the presence of metal aluminum, reducedThe activity of oxygen is more conducive to the removal of sulfur from steel (iron) water. In the process of hot metal pretreatment, AD powder has better desulfurization effect and lower cost than the desulfurizer made of other materials.

3, foaming. In the refining process, AD powder can be foamed in one minute :A203 and SiC components can maintain appropriate high temperature fluidity and surface tension, so the submerged arc performance is good, the heating speed is fast, and the electrode power consumption is greatly reduced. The foaming mechanism of AD powder is mainly the reduction reaction between the carbon of the electrode and a small amount of carbon in AD powder and FeO, MnO, SiO2 in the slag at high temperature to generate CO and other bubbles. And add carbonates, such as CaCO. , BaCO, etc., because they completely decompose at about 900, at a refining temperature above 1600, the time maintained by carbonate decomposition foam is limited.
4, remove inclusions in steel. Due to the viscosity and surface tension at the high temperature of refining, it is easy to absorb the calcium oxide in the steel, and with the agitation of the bottom hydrogen, the inclusions in the steel float and are adsorbed by AD powder. According to the different refining time, under normal circumstances, the total amount of inclusions in steel can be reduced by more than 50%, and the effect of purifying molten steel is very obvious, which is suitable for the production of high-quality steel. In addition, the effect of AD powder making white slag is particularly good, shortening the refining time and improving the refining efficiency. At present, several major special steel mills in China are using our company’s AD powder when refining bearing steel and have achieved good results.

Refining agents also have the following advantages in daily use
1: The amount of addition is small, the ability to accumulate slag is strong, and it is easy to crust.
2: The product is a composite slag collector with slag collection, heat preservation, covering multiple functions.
3: the slag is simple, do not leave scattered floating matter, do not stick to the bag, do not damage the wall, the furnace wall.
4: Heat preservation, reduce the loss of dilute alloy elements,
5: reduce harmful elements such as phosphorus and sulfur in liquid metal.
6:: The product has no pollution to the solution, strong permeability, and does not affect its chemical composition. No smoke, no harmful gases, can purify the furnace working environment.
7: When the product is covered on the nodulating agent, it can delay the nodulating reaction time, improve its absorption rate, reduce the amount of nodulating agent and reduce the cost.
8: Eliminate casting slag inclusion, improve casting quality, reduce casting scrap rate.
