Preparation Method of Acid-Resistant Refractory Castable
The general composition of acid-resistant refractory castables is as follows: 60%-70% acid-resistant refractory aggregate, 30%-40% powder, and 13%-16% water glass solution with a density of 1.38-1.42 g/cm3. When sodium fluorosilicate is used as a hardening accelerator, its addition amount is Read More …
What are the Most Important Points in the Construction Process of Refractory Castables?
Due to its advantages, such as a simple production process and convenient construction, refractory castables have been widely used by enterprises. However, the performance of refractory castable linings is not only related to their own performance and quality, but also Read More …
How to Improve the Medium Temperature Strength of Refractory Castables – Rongsheng High Strength Castables
The strength change characteristics of refractory castables are closely related to the hydration products of aluminate cement and the physical and chemical changes after heating. The microscopic changes in the heating process of aluminate cement are reflected macroscopically in the Read More …
