Abstract

The invention relates to a plurality of assistant materials of slagging materials and a preparation method, belonging to metallurgy field, which is characterized in comprising the components in the following weight matching: steel slag of converter 8.0 to 9.5 shares and addition agent 0.5 to 2 shares; wherein, the addition agent comprises the components in the following weight percentage: Na2CO3 is 5.00 to 10.00 percent, FeO is 70.00 to 80.00 percent and BaCO3 is 10.00 to 20.00 percent. The assistant materials of slagging materials can be used in slagging and also used as slugging agent and dephosphorizing agent. The invention achieves the recycle utilization of the steel slag of converter, therefore has the advantages of lowering the amount of waste slag during steel-making, saving the dosages of current slagging material: lime and dolomite and improving the slagging performance, and also has the advantages of slagging rapid, sludging rapid and dephosphorizing effectively. The invention provides a new method to recycle the steel slag of converter for people.

Description

technical field [0001] The invention relates to a multifunctional slagging material auxiliary material and a preparation method thereof, belonging to the field of metallurgy. Background technique [0002] Converter steel slag is one of the "three wastes" of the iron and steel industry. It contains a certain amount of steel scrap and useful component resources such as CaO, FeO, SiO2, and MgO. environmental pollution. The recycling of converter steel slag can reduce the total amount of waste slag in steelmaking plants and save a lot of slagging materials. Therefore, the comprehensive utilization of converter steel slag has been incorporated into an important link in the development of circular economy in the iron and steel industry. [0003] At present, the comprehensive utilization rate of converter steel slag in my country is only 36%, which is mainly used for recycling slag iron, metallurgical raw materials, building materials, and pre-desiliconization and dephosphorizatio...
