Iron oxide scale pellet binder is a material used to bond iron-containing waste materials such as iron oxide scale, converter sludge, and dust removal ash into pellets. The following are some detailed information about iron oxide scale pellet binder:
Main Components
The main components of iron oxide scale pellet binder typically include high molecular polymers, sodium-based bentonite, boron-magnesium-containing beneficiation tailings, alkaline sodium silicate, cold-soluble polyvinyl alcohol, polyacrylonitrile fiber, and light calcium carbonate.
Performance Characteristics
- High forming rate: Low addition amount, good forming hardness, and pelletizing rate up to 98%.
- High strength: Cold strength ≥800N, resistant to high temperatures up to 1200°C without disintegration or powdering.
- Improved hydrophilicity: Enhances the hydrophilicity of the mixture, facilitating pellet formation.
- Environmental friendliness: Does not alter the properties of the materials, does not increase ash content, and does not reduce calorific value.
Usage Method
- Mix ore powder, binder, and water in proportion and stir to form pellets.
- The binder can first be dissolved in water to form a colloid and then added to the powder material to effectively exert its binding effect.
Application Areas
- Primarily used in the metallurgical industry to pelletize waste materials such as iron oxide scale, serving as a cooling agent and slag-forming agent in steelmaking to reduce production costs.
- Also applicable to the cold-bonded pellet production of other iron-containing materials, such as chromite ore powder agglomeration.
Precautions
- During use, it is necessary to control humidity and ensure thorough mixing before pellet pressing.
- Store in a dry environment to avoid moisture affecting the binding effect.
In summary, iron oxide scale pellet binder holds significant application value in the metallurgical industry, effectively improving resource utilization, reducing production costs, and meeting environmental requirements.
