Are you still struggling to decide on the appropriate corundum content for your flash furnace? Rear Half of the Rising Flue Short-term temperature fluctuations of 800–1450℃, large temperature differences, and frequent thermal shocks; the main components of the acidic sulfur-based…
An Indian cement plant wanted to replace the refractory bricks in its transition zone. The client reported damage to the bricks during operation, primarily surface cracking and spalling. This led to plant shutdowns, reduced output, increased refractory material costs, and…
Today I’d like to share a case study: our Indian client’s 10-ton copper smelting converter. Judging from the drawings, this is a converter. Generally, a furnace consists of a working layer, an insulation layer, and a permanent lining. The working…
On March 13, 2026, we received our Indian client and held a brief meeting to arrange a factory visit and design consultation. On March 14, we led our Indian client on a factory tour, showcasing our raw material workshop,…
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…
