Embodiment Construction

[0013] The present invention is further described in conjunction with above-mentioned technical scheme and embodiment:

[0014] Below is the detailed embodiment of specific implementation mode:

[0015] 1. A magnesium-based organic binder for ironmaking pellets, characterized in that its components by weight percentage are: organic high-viscosity material 0.025-0.075.0%; carrier 99.975-99.925%.

[0016] 2. The organic high-viscosity material is composed of one or a mixture of carboxymethyl cellulose and water-soluble resin. When the concentration of carboxymethyl cellulose is 1%, the viscosity is ≥300mpa.s; when the concentration of water-soluble resin is 1%, the viscosity is ≥350mpa.s. These highly viscous materials are highly hydrophilic and have strong adhesion to ferrous materials.

[0017] 3. The carrier is brucite {Mg(OH) 2} and a combination of one or two mixtures of lightly burned magnesium powder.

[0018] 4. The carrier is brucite {Mg(OH) 2} and one or two mixtu...

Abstract

The invention relates to a manufacturing method for a magnesium-based organic binding agent used for iron making pellet ore in the technical field of bonding agents for metallurgy. The magnesium-based organic binding agent comprises, by weight percent, 0.025%-0.075.0% of an organic high-viscosity material and 99.975%-99.925% of a carrier. The organic high-viscosity material is one of carboxymethyl cellulose and water soluble resin or a mixture of the carboxymethyl cellulose and the water soluble resin, and the organic high-viscosity material has very high cohesiveness on iron-containing materials. The carrier is one of brucite {Mg(OH)2} and caustic-burned magnesia powder or a mixture of the brucite {Mg(OH)2} and the caustic-burned magnesia powder, the granularity of the carrier is smaller than the 0.044 mm, and the particle size mass percent of the carrier is larger than or equal to 95%. The organic high-viscosity material and the carrier are evenly mixed according to a proportion and are subjected to co-grinding, the granularity of the mixed material is smaller than or equal to 0.044 mm, and the particle size mass percent of the mixed material is larger than or equal to 90%. The binding agent can reach the fine granularity, sufficient scattering and mixing of the binding agent in the iron materials are facilitated, and the pelletizing effect is improved.

Description

technical field [0001] The invention discloses a method for manufacturing a magnesium-based organic binder for ironmaking pellets, belonging to the manufacturing method in the technical field of metallurgical binders. Background technique [0002] 1. Ironmaking pellets have the advantages of good metallurgical properties and improved air permeability of the blast furnace charge column, and are considered to be a high-quality charge for optimizing the structure of the blast furnace charge. In order to meet the requirements for the chemical composition, strength and metallurgical properties of the iron concentrate production pellets and blast furnace smelting, it is necessary to add a certain amount of binder to the pellets. At present, the most widely used binder is bentonite, including calcium bentonite, sodium bentonite and artificial sodium bentonite. The main component of bentonite is Sio 2 and Al 2 o 3 , adding in the pellet feed will reduce the grade of pellets and ...
