What is silicon aluminum barium calcium？
   Silicon aluminum barium calcium has a lower solubility in molten steel, and can dissolve calcium and reduce calcium vapor pressure. In silicon aluminum barium calcium alloys, it can fully enhance the role of calcium in deoxidation and non-metallic inclusion treatment. Silicon aluminum barium calcium is a deoxidizer and desulfurizer in barium based alloys, which can reduce the oxygen content in steel. At the same time, complex inclusions such as calcium, barium, and aluminum formed are easy to float from the pot liquid, purify the steel liquid, and improve the impact toughness and processing performance of steel.

What are the uses of silicon aluminum barium calcium?
  (1)Silicon aluminum barium calcium is a highly effective deoxidizer and desulfurizer. It is an alloy deoxidizer and composite deoxidizer produced by smelting ores containing elements such as silicon, aluminum, barium, and calcium. It plays an important role in deoxidation and desulfurization in both steelmaking and casting.

  (2)Moreover, silicon calcium barium aluminum is a good deoxidizer and desulfurizer in barium based alloys, reducing the oxygen content in steel to a very low level. At the same time, the complex oxides containing calcium, barium, silicon, and aluminum formed are easy to float up from the steel liquid, purifying the steel liquid and improving its impact toughness and processing performance.
  Overall, silicon aluminum barium calcium has strong deoxygenation and desulfurization effects, which can effectively improve the flow performance of molten steel and solve the problem of nozzle nodules. Reduce gas in steel and reduce inclusions in molten steel. So, it is widely used in the steelmaking industry and has good development prospects in the market. Both in casting and steelmaking, it plays an important role in deoxygenation and desulfurization, and the price is not very high, which can be fully accepted by steel mills and foundries. Therefore, its application in the market is becoming increasingly widespread.

  (3) Due to the fact that most steelmaking in our country has been achieved through continuous casting, the aluminum content in deoxidizers is high. During the deoxidation process, due to the presence of aluminum, Al2O3 will be produced, causing nozzle nodules and affecting production and output. Meanwhile, some steel grades do not require aluminum, and the presence of aluminum can lead to inclusions of Al2O3 in the steel, which affects the quality of the steel. Given the above two reasons, it is urgent to use aluminum free deoxidizers for deoxidation. Silicon barium calcium alloy is a new type of composite alloy in the barium series, which is a deoxidizer, desulfurizer, and also has the function of dephosphorization in steelmaking; It is a inoculant and modifier in casting. Barium reduces the vapor pressure of calcium within the temperature range of steelmaking, and increases the solubility of calcium in molten steel. Compared with silicon calcium alloy, when using silicon barium calcium alloy as a calcium source to add to the steel liquid, even when the amount of calcium added is half of that of silicon calcium alloy, the calcium content in the steel liquid is about twice that of silicon calcium alloy, and calcium in the steel liquid is also significantly increased. It fully demonstrates that barium protects calcium in molten steel, reduces calcium oxidation, and thus achieves the goal of treating calcium in molten steel

How to apply silicon aluminum barium calcium?
  (1)After deoxidation, the product of silicon aluminum barium calcium is easy to float and discharge, so the steel liquid deoxidized with silicon aluminum barium calcium alloy is relatively pure. When refining high-quality steel, silicon aluminum barium calcium alloy is commonly used as a deoxidizer. The calcium in silicon aluminum barium calcium alloy forms a stable compound CaS with sulfur, and CaS is insoluble in steel water. Therefore, when deoxidizing silicon aluminum barium calcium alloy, it also has the function of desulfurization. In the production of cast iron, silicon aluminum barium calcium can better change the properties of cast iron than silicon iron. Silicon aluminum barium calcium alloy is not only a good inoculant to promote the formation of spherical graphite, but also has the effects of deoxidation, desulfurization, denitrification, and silicon enhancement. So, silicon aluminum barium calcium is a very effective composite deoxidizer and desulfurizer.

 (2) Silicon aluminum barium calcium can also be applied in the field of casting. By adding silicon aluminum barium calcium to molten iron, the silicon element can have a good incubation effect, while the addition of other elements can also have a spheroidizing effect. Compared with single smelting products, silicon aluminum barium calcium has good results in casting, which also leads to a large amount of use of silicon aluminum barium calcium in casting

How to produce silicon aluminum barium calcium?
    (1)Firstly, mix silica, bauxite, and coke evenly, and add them to a submerged arc furnace for smelting to produce silicon aluminum alloy. Then add CaO and coke in batches to promote the formation of silicon calcium aluminum. Add barium ore and coke in batches to promote the formation of silicon calcium barium aluminum alloy. The general composition of silicon calcium barium aluminum alloy is: Si greater than 30%, Ca greater than 6%, Ba greater than 9%, and Al greater than 8%.

   (2)In production, it is necessary to control the ratio of Al2O3/SiO2, CaO/BaO, (CaO+BaO)/SiO2, and control the amount of coke added.

   (3) The equipment parameters should choose higher current and lower operating voltage, with higher pole center power and higher furnace power. Maintain a high temperature in the reaction zone of the furnace. From beginning to end, the method of stewing and burning should be used, and the accumulated slag should be treated by adding CaO and BaO to remove it from the furnace.

    (4) When producing silicon calcium barium in large electric furnaces, the method of hot stamping aluminum ingots can be used to produce silicon calcium barium aluminum alloys. But this method does not produce silicon calcium barium aluminum alloy with ore and has a good economic effect.

How to choose silicon aluminum barium calcium?
   (1)Don't be tempted by small gains when purchasing silicon, aluminum, barium, and calcium,Silicon aluminum barium calcium is much lower than the normal supply price, often due to counterfeit or insufficient content of products. Customers often cannot achieve the expected results after purchasing and using them

   (2)Choose experienced silicon aluminum barium calcium manufacturers for procurement,The operating time of silicon aluminum barium calcium manufacturers is often an important reference for customers to consider cooperation when purchasing. Silicon aluminum barium calcium manufacturers with longer operating time and older qualifications often have certification certificates issued by authoritative institutions for their silicon aluminum barium calcium products, ensuring product content

Avoid purchasing silicon aluminum barium calcium from freight forwarders and intermediaries,Intermediaries and freight forwarders often need to earn a price difference for the supply of silicon, aluminum, barium, and calcium. In order to protect their own interests, they sometimes purchase silicon, aluminum, barium, and calcium at lower prices. These silicon, aluminum, barium, and calcium have insufficient content or poor quality and effectiveness, and customers can only consider themselves unlucky after purchasing!
