Abstract

The invention discloses an additive for improving coke quality and a preparation method thereof. The additive for improving the coke quality comprises the composition and content: 3-5 parts of TiB2, 5-8 parts of calcium phenoxide and 4-7 parts of SiO2. The preparation method of the additive for improving the coke quality comprises the following steps: adding TIB2 blended in a certain proportion and the drying degree of 90%-95%, calcium phenoxide and SiO2 to a superfine pulverizer in turn and grinding circularly to ensure that the final particle fineness is between 0.05 and 0.1 mm, and then fully stirring uniformly.

Description

technical field [0001] The invention relates to the field of health-care convenience food, in particular to an additive for improving coke quality and a preparation method thereof. Background technique [0002] Coke is an important metallurgical energy. Coke plays four major roles in the process of blast furnace ironmaking: material column skeleton, heat source, carburizing agent and reducing agent. The quality of coke has a great influence on the smooth operation of the blast furnace and the technical and economic indicators of blast furnace smelting. With the development of blast furnace coal injection technology, the role of coke as a heat source, reducing agent, and carburizing agent is gradually weakened, which means that the volume occupied by coke in the blast furnace column is greatly reduced; and after the blast furnace is enlarged, the height of the furnace body increases , the various forces borne by the coke in the material column will also increase, and at the ...
