The production process of fire-resistant material electric fused magnesia products typically involves the following steps:
1. Raw material preparation: The first step is to obtain high-quality magnesite ore. The ore is then crushed, ground, and screened to ensure consistent particle size and purity.
2. Calcination: The crushed magnesite is then heated in a rotary kiln or a shaft kiln at high temperatures (around 1500°C) to remove impurities and convert it into magnesia clinker.
3. Briquetting: The magnesia clinker is mixed with a binder and pressed into briquettes or pellets of the desired shape and size. This process improves the density and strength of the final product.
4. Electric melting: The briquettes or pellets are then placed in an electric arc furnace. The furnace is heated to extremely high temperatures (above 2800°C) using electric current. This intense heat causes the magnesia to melt and form a liquid.
5. Cooling and solidification: Once the magnesia has melted, it is allowed to cool and solidify. This process may involve controlled cooling rates to achieve desired crystal structures and minimize defects.
6. Crushing and grading: The solidified magnesia is crushed into smaller particles and then graded according to particle size. This ensures uniformity and consistency in the final product.
Packaging and storage: The final product is packaged in suitable containers or bags for storage and transportation. Proper labeling and documentation are also important for quality control and traceability.
Throughout the production process, quality control measures are implemented to ensure that the final product meets the required specifications and performance standards. These may include chemical analysis, physical property testing, and visual inspection.
