Vacuum Formed Refractory Shapes, also known as aluminum silicate plugs, insulation tap out cones, and refractory fiber cones. The aluminum silicate plug is suitable for the heat insulation and sealing of the outlets of aluminum smelting furnaces, refining furnaces, stationary furnaces, etc., making the aluminum alloy casting process more convenient and safer.
The ceramic fiber shaped parts are made of high-quality ceramic fiber cotton as a raw material and made by vacuum forming process. Vacuum Formed Refractory Shapes are ceramic fiber shaped products that are directionally produced to meet the fire resistance and heat insulation of special parts of certain thermal equipment. It has the rigidity with superior high temperature performance and the special-shaped products with self-supporting strength.
Vacuum Formed Refractory Shapes parts are all shaped products that meet the specific production links of certain industrial sectors. Each product needs to make a special mold according to its shape and size. According to the performance requirements of the product, unused bonding agents and additives are selected to meet the use requirements.
Vacuum Formed Refractory Shapes Features
- Tough texture and strong resistance to wind erosion; seamless lining.
- Low heat storage and less heat loss, can directly contact the flame for hot surface.
- Excellent construction and installation performance, excellent thermal shock resistance.
- High compressive strength, long service life, and remarkable sound absorption effect.
- No toxic gas will be released, moisture resistance is good, and shock resistance and pressure resistance will not be broken.
All Vacuum Formed Refractory Shapes products have a low shrinkage in the temperature range of their use, and maintain the characteristics of high heat insulation, light weight, and impact resistance.
Unheated materials are easily cut or machined. During use, the product has good resistance to abrasion and flaking, and is not wetted by most molten metals.
Vacuum formed special-shaped products can have a variety of sizes and shapes, including tube, cone, dome and square box shape, most of the special-shaped products can be produced according to customer requirements, but some special-shaped products can also be stocked for customers. For example, there are casting caps and sleeves for non-ferrous metals industry, and vacuum forming and fire holes for petrochemical industry. The physical and thermal characteristics of various shaped products are generally similar to the performance of the corresponding level of vacuum forming board. If necessary, vacuum forming hardener or refractory clay can be applied to the shaped products to provide a protective layer.
The product is a non-brittle material with high strength and accurate size. It can be produced in various forms according to customer needs. The refractory fiber cone product has good fire resistance and heat insulation effect, and can directly contact the flame.
