Product Description:
Ceramic fiber shaped products are made of high-quality ceramic fiber cotton by vacuum forming process. The purpose of developing this product is to make a rigid and self-supporting special-shaped product with superior high-temperature performance.
Ceramic fiber special-shaped products are special-shaped products that meet the needs of specific production links of some industrial departments. Special molds are made for each product according to its shape and size. Unused binders and additives are selected according to the performance requirements of the product to meet the use requirements.
All special-shaped products have low shrinkage within their service temperature range, and maintain the characteristics of high heat insulation, light weight and impact resistance.
Unburned materials can easily be cut or machined. In the process of use, the product has good wear and peeling resistance, and is not wetted by most molten metals.
Shape and supply: vacuum formed special-shaped products can have a variety of sizes and shapes, including tube shape, cone shape, dome shape and square box shape. Most special-shaped products can be produced according to customers’ requirements, but some special-shaped products can also be stored for customers, such as casting caps and sleeves for non-ferrous metal industry, vacuum formed fire holes for petrochemical industry, etc.
General characteristics: the physical and thermal characteristics of various special-shaped products are generally similar to those of vacuum formed plates of corresponding levels.
Special treatment: if necessary, vacuum forming hardener or refractory mud can be applied to special-shaped products to provide a protective layer.
