Product Introduction
Products parameters
The Fuse Casings Ceramic is a key component of the fuse. It is made of ceramic material and has excellent insulation and mechanical strength. It contains a fuse. When the circuit is overloaded, the fuse will melt due to heat, thereby cutting off the circuit and protecting the electrical equipment from damage. The design of the ceramic body ensures that the fuse can work safely and effectively under extreme conditions.

production process
1. Raw material preparation: First, you need to select suitable raw materials, including ceramic powder, rare earth elements, metal elements, etc., which are the basic components of Fuse Casings Ceramic.
2. Ingredient mixing: Alumina, magnesium oxide, silicon dioxide, zirconium oxide, ABO3 coated carbon nanotubes, sintering aids, etc. are mixed in a certain proportion. These raw materials will determine the final performance of the products.
3. Ball milling and drying: The mixed raw materials need to be ball milled and dried to increase the uniformity and fluidity of the raw materials in preparation for the subsequent molding steps.
4. Molding: The dried raw materials are added with a binder for granulation, and then pressed to form the desired ceramic body shape.
5. Sintering: The formed green body needs to be sintered at high temperature, usually between 1450-1550℃, and the sintering time is 2-4 hours to form a hard ceramic body.
6. Cooling: After sintering, the green body is cooled to room temperature with the furnace. This step is crucial to maintaining the structural integrity and performance of the pdoducts.
7. Performance test: The sintered ceramic body needs to be tested for performance, including mechanical strength test and thermal shock resistance test, to ensure that it meets the use requirements of high-break fuses.
8. Quality inspection: The appearance and internal quality of the ceramic body are inspected to ensure that there are no defects such as cracks, bubbles, etc., to ensure the reliability of the product.
9. Assembly: Qualified Electrical Alumina Ceramic Fused Body will be used to assemble fuses and assembled into complete fuse products together with other components such as fuse wires, electrodes, etc.
