The production process of refractory shaped products can be divided into several main steps. The following is a detailed introduction:
1. Raw material preparation: First, the required raw materials need to be prepared, including refractory clay, high-temperature polymer resin, fillers and additives, etc. These raw materials are formulated and screened according to the requirements of specific products.
2. Mixing and preparation: In this step, the raw materials are mixed according to a certain ratio, and an appropriate amount of water or solvent is added. Through stirring and mixing equipment, ensure that the raw materials are fully and evenly mixed into a slurry or paste.
3. Molding: The mixed materials will be shaped by molding equipment such as molds or extruders. These devices compress materials into desired shapes such as bricks, panels, pipes or complex shaped components.
4. Drying and curing: The formed product needs to be dried and cured to remove moisture or solvent, and to make it have certain strength and fire resistance. The drying and curing methods can be natural drying, air drying or accelerated drying through ovens, drying rooms and other equipment.
5. Sintering or calcining: Some refractory materials need to be further sintered or calcined to improve their density, strength and refractory performance. This step, usually performed at high temperatures, allows the particles in the material to combine and form a strong product.
6. Surface treatment and packaging: Finally, the sintered or calcined refractory products will be surface treated, such as grinding, spraying or coating with a special protective layer. Then, according to customer requirements, the product is packaged and labeled, ready for dispatch or storage.
This is a basic production process of refractory shaped products. The exact process may vary by product type, specification and application area. Manufacturers usually adjust and optimize processes according to needs to ensure the production of refractory products that meet quality standards and customer requirements.
