The Advantages And Usage Of Compound Deoxidizer
Nov 04, 2021
There are many kinds of metallurgical materials that can be used as steelmaking deoxidizers, however, the composite deoxidizer can be widely used, mainly because the composite deoxidizer has many outstanding advantages compared with the single element deoxidizer. As our company has been in contact with the compound deoxidizer for many years, so the understanding of the compound deoxidizer is also very comprehensive and detailed, in order to return the support of the majority of users over the years, will be at home to briefly talk about the advantages of the compound deoxidizer and usage.
1、High deoxidation efficiency, fast. Compound deoxidizer is added to the steel in a certain proportion, can quickly form an active and stable white slag, without adding another deoxidizing alloy (such as ferrosilicon aluminum, calcium barium silica or barium silica aluminum, etc.), you can achieve the final deoxidation requirements.
2, high alloy yield, adsorption of inclusions, purify the steel. Due to the high efficiency of composite deoxidizer deoxidation, reduce alloy material powder, not only has excellent deoxidation, desulfurization function, and can make the oxide inclusions spherical, stable adsorption in the slag, to purify the metallurgical purpose of the steel.
3, applicable to a wide range of steel, less dosage, the viscosity of the slag is small, easy to pour slag. Compound deoxidizer is not only applicable to unrefined plain carbon steel but also adapted to the refining of low-alloy steel, medium and high carbon steel, and special alloy steel grades. 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 made is thin, does not stain the ladle wall, easy to pour slag. 4、Compound deoxidizer is low in price, easy to transport, does not absorb moisture, does not powder, safe to use, no stock hidden danger. Use method and composition
Compound deoxidizer has many advantages, in addition to the application of compound deoxidizer is also very simple and convenient. The amount of compound deoxidizer added is determined by the carbon content of the end steel. Generally, it is added by 1.0-1.5kg/ton steel. The compound deoxidizer is added directly to the bottom of the ladle before the steel is discharged, and ferromanganese, ferrosilicon, and aluminum are added as a rule when the steel is discharged 1/4.
