Abstract

The invention discloses a novel disc pelletizing and sintering pellet binder and a preparation method thereof, the novel disc pelletizing and sintering pellet binder comprises calcium oxide, magnesium oxide, a tackifier, a water reducing agent and an organic high-molecular polymer, and the novel disc pelletizing and sintering pellet binder comprises the following components in percentage by mass: 40-52% of calcium oxide, 3-10% of magnesium oxide, 3-5% of the tackifier, 8-12% of the water reducing agent and 33-38% of the organic high-molecular polymer. The organic high-molecular polymer is set to be a water-soluble organic high-molecular polymer, the organic high-molecular polymer becomes a high-viscosity liquid after encountering water, the addition proportion is set to be 1-2% when the novel disc pelletizing and sintering pellet binder is used, and the optimal addition proportion is set to be 1.6% when the novel disc pelletizing and sintering pellet binder is used. When the novel binder is used, the quality of finished product pellets adopting the novel binder is superior to that of pellets prepared by adding bentonite. And by matching the novel binder, the pellet quality can be improved, the system cost before iron making is reduced, and conditions are created for improving the blast furnace productivity.

Description

technical field

[0001] The invention belongs to the technical field of disc pelletizing adhesives, in particular to a novel adhesive for disc pelletizing and sintering pellets; in particular, it also relates to a novel adhesive for disc pelletizing and sintering pellets and its preparation method. Background technique

[0002] In recent years, the production of pellets based on disc pelletizing, chain grate machine or rotary hearth furnace sintering technology has developed rapidly in the prior art. Pellets have become one of the main raw materials for blast furnaces. Pellets have good metallurgical properties, and because of their spherical shape, the air flow resistance is small, which can improve the air permeability of the upper part of the blast furnace and help increase the productivity of the blast furnace.

[0003] At present, most of the binder used in the pelletizing industry is bentonite. Due to the addition of bentonite, the SiO of the pellets is increased. 2 ...
