How much is the charge for insulation and refractory castables? The price of insulation refractory castables is greatly affected by material, density, performance, and procurement volume. Zhengzhou and Henan regions are concentrated in the refractory industry, and the prices of different types of products vary significantly. Combined with the market quotations of local manufacturers (such as Zhengzhou related refractory enterprises), the final transaction price of insulation refractory castables is mainly determined by the material and content (such as alumina content), bulk density (specific gravity), as well as specific temperature and environmental requirements for use. Clarifying these technical parameters during procurement is a prerequisite for obtaining accurate quotations.
