The pelletizing binder in steel plant auxiliary materials is primarily used to compress iron-containing waste (such as dust, sludge, steel slag, etc.) generated in steel plants into pellets, facilitating resource reuse and reducing environmental pollution. Below is some information about pelletizing binders for steel plant auxiliary materials:
Types and Characteristics of Binders
- Air-drying binder: Pellets can achieve high strength naturally within 24 hours, with low additive usage, high forming hardness, no alteration of ore grade, high pelletizing rate, and no harmful emissions such as phosphorus or sulfur after combustion, making it clean and environmentally friendly.
- Calcium oxide-resistant binder: Designed for raw materials with high calcium oxide content, it contains anti-calcium components, resulting in high pellet strength, long-term resistance to pulverization, and some products being odorless, which benefits production and worker health.
Binder Composition
- Mainly composed of organic substances, supplemented with tackifiers, reinforcing agents, modifiers, etc., using various high-molecular environmentally friendly materials, free of harmful elements such as sulfur and phosphorus.
Production Process
- The binder is mixed with raw materials in proportion, stirred with water, and then formed through a pelletizing machine. Some binders can be used directly without drying, saving energy and time.
Performance Advantages
- Strong adhesion, high forming rate, excellent cold compression strength and temperature resistance, meeting the strength requirements of metallurgical furnaces while reducing production costs and enabling efficient resource utilization.
In summary, pelletizing binders for steel plant auxiliary materials play a crucial role in the steel industry, promoting the transition to green development and making positive contributions to environmental protection.
