The core principle of using silicon bricks in coke ovens is to leverage their high-temperature stability, sensitivity to rapid heating and cooling, and susceptibility to moisture and alkali. The core approach is “precise construction + rigorous oven drying + stable…
A coke oven is a core thermal equipment in the iron and steel metallurgical industry, used for the dry distillation of coking coal into coke. Its interior is subjected to harsh environments of high temperature, periodic thermal shock, chemical erosion,…
The cost of silica bricks is influenced by multiple factors, including raw materials, processing, and compliance, with an overall range of approximately 1800-14000 RMB The core differences stem from raw material purity, production processes, and product specifications. Raw material costs…
Today, a group of Vietnamese customers visited Ruitai to inspect the production process and product quality of silica bricks for glass kilns. We received them with professionalism and courtesy throughout, strictly adhering to Vietnamese business etiquette, to facilitate a deeper…
Silica bricks, as a core acidic refractory material, are widely used in high-temperature industrial kilns such as coke ovens, glass melting furnaces, and open-hearth steelmaking furnaces due to their excellent high-temperature stability and resistance to acidic slag erosion. Their quality…
Silica fire bricks, as a commonly used refractory material, are priced due to a combination of factors. The core fluctuations revolve around three main areas: cost, quality, and market supply and demand. 1. Raw material costs Raw material costs form…
Silica bricks are acidic refractory materials made from silica with a SiO₂ content ≥94%, combined with mineralizers and fired at high temperatures. The core consists of tridymite, cristobalite, and residual quartz. Advantages of silica bricks Their advantages lie in their…
Silica fire bricks are acidic refractory materials with silicon dioxide (SiO₂) as the main component (usually not less than 94%). They possess core advantages such as high refractoriness (1700~1730℃), good high-temperature volume stability, and high load softening temperature (1640~1670℃). However,…
Recently, a Nigerian customer consulted us regarding the need for refractory materials to repair damaged areas of the rotary kiln’s firing zone. The customer required refractory materials to repair the firing zone. Ruitai’s technical team provided a professional repair solution.…
The refractory materials lining the inner wall of a rotary kiln are crucial for resisting high temperatures, corrosion, and wear, directly affecting the equipment’s service life and production stability. Appropriate materials must be selected based on the working environment of…
