advantages of composite deoxidizer

　　There are many types of metallurgical materials that can be used as deoxidizers for steelmaking. However, the wide application of composite deoxidizers is mainly due to the fact that composite deoxidizers have many outstanding advantages compared with single element deoxidizers. Since our company has been in contact with composite deoxidizers for many years, we have a very comprehensive and detailed understanding of composite deoxidizers. In order to return the support of many users for many years, we will briefly talk about the advantages and usage of composite deoxidizers at home.

　　     1. High deoxidation efficiency and fast speed. The compound deoxidizer is added to molten steel in a certain proportion to quickly form active and stable white slag. It does not need to add other deoxidizing alloys (such as silicon aluminum iron, silicon calcium barium or silicon aluminum barium, etc.) to achieve the final deoxidation requirements.

　　     2. High alloy yield, adsorb inclusions and purify molten steel. Because the composite deoxidizer has high deoxidation efficiency and reduces alloy material powder, it not only has excellent deoxidation and desulfurization functions, but also can spheroidize the oxide inclusions and stably adsorb in the slag, achieving the metallurgical purpose of purifying molten steel.

　　     3. It is applicable to a wide range of steel grades, less dosage, and low slag viscosity, which is convenient for slag dumping. The compound deoxidizer is not only suitable for unrefined normal carbon steel, but also suitable for refined low alloy steel, medium and high carbon steel and special alloy steel. At the same time, it can shorten the refining time and improve the hit rate and recovery rate of the alloy. The dosage is generally 1.0-1.5㎏/ton steel, the slag produced is thin, does not stick to the wall, and is convenient for slag dumping.

　　　　 4. The composite deoxidizer has low price, convenient transportation, no moisture absorption, no powdering, safe use, and no hidden danger of inventory. Usage and ingredients.

     In addition to the many advantages of composite deoxidizers, it is also very simple and convenient when applying composite deoxidizers. The amount of compound deoxidizer added is determined by the carbon content of the final molten steel. It is generally added at 1.0-1.5kg/ton steel. The composite deoxidizer is directly added to the bottom of the package before tapping, and ferromanganese, ferrosilicon, and aluminum are added as usual when tapping 1/4.
