Converter kilns are the core carriers of steelmaking. Furnace bricks for converters are the core lining that protects the long-term operation of the kiln. The two are interdependent and work synergistically to support the crucial link in high-temperature smelting. Then…
As the core equipment in lead smelting, lead smelting converters operate under harsh and complex conditions. In order to enduring long-term high-temperature smelting, slag erosion, lead penetration, and flue gas scouring. The selection of kiln bricks directly determines the converter’s…
Non-ferrous metal smelting kilns operate under harsh conditions of high temperature, strong corrosion, and molten slag erosion. The performance of the refractory bricks directly determines the kiln’s service life and production stability. Therefore, it is essential to select specialized refractory…
Chemical Properties Magnesia-chrome bricks are alkaline refractory materials with MgO and Cr₂O₃ as their core components. The mineral phases are mainly periclase and spinel. Their core chemical properties are high chemical stability, strong resistance to slag erosion, high-temperature phase stability,…
Composition of Silica Bricks The core component of silica bricks is SiO₂ (silicon dioxide), supplemented with small amounts of additives and impurities. They are acidic refractory bricks made primarily from quartz raw materials, which undergo a crystal transformation during high-temperature…
Refractory bricks are core consumables in high-temperature industries such as metallurgy and building materials. Their manufacturing requires multiple precise processes to ensure high-temperature resistance, corrosion resistance, and wear resistance. Raw material selection Raw material selection is fundamental, primarily using…
Refractory bricks for kilns are widely used in various industrial fields such as cement, ceramics, metallurgy, glass, and chemicals. Mature adaptation solutions have been developed for the characteristics of kilns in different industries: Cement Industry The firing zone of…
Magnesia spinel fire bricks are alkaline refractory fire bricks with periclase (MgO) and magnesia-alumina spinel (MgAl₂O₄) as the main mineral phases. They are high-performance refractory materials, combining the high refractoriness and alkali resistance of periclase with the thermal shock resistance and slag…
Magnesia-chrome fire bricks are alkaline refractory fire bricks primarily composed of periclase (MgO) and chromite (FeO・Cr₂O₃). Key Indicators: MgO and Cr₂O₃ Ratio: Higher total MgO and Cr₂O₃ content indicates fewer impurities, resulting in stronger high-temperature resistance and erosion resistance. Apparent…
Chemical Composition of Magnesia fire bricks Magnesia fire bricks are alkaline refractory materials with magnesium oxide (MgO) as the main component and periclase as the main crystalline phase. They are classified into: ordinary magnesia fire bricks, direct-bonded magnesia fire…
