GB/T 16763-1997 is the classification standard for shaped thermal insulation refractory products. It systematically classifies shaped thermal insulation refractory products according to the material of the product, such as clay, high aluminum, etc., as well as key performance indicators such as operating temperature and bulk density. Detailed division of the characteristics of different categories of products provides clear guidelines for the production and selection of shaped thermal insulation refractory products, which is convenient for various industries to accurately match the applicable refractory products according to actual needs in high temperature industrial kilns and other scenarios, to improve the safety and Stability of industrial production, and to help the development of related industries.
