In global steel production, 60%-70% of refractory bricks are used for smelting. Developed countries such as Europe, America, and Japan dominate the high-end market, forming an application system centered on high performance, low carbonization, and long service life.
Foreign steel mills focus on high-end products such as low-carbon magnesia-carbon bricks, high-purity aluminum-carbon bricks, and chromium-free basic bricks for their core furnaces. These products are suitable for various working conditions such as converters, electric arc furnaces, and continuous casting, balancing the purity of molten steel and the lifespan of furnace linings. Low-carbon processes like hydrogen metallurgy utilize high-purity corundum and mullite refractories to withstand severe reduction conditions.
Green and intelligence are the core trends: the recycling rate of refractory bricks in the European Union and Japan exceeds 30%, and low thermal conductivity and energy-saving linings help green production; monolithic refractories account for more than 40%, offering convenient construction and longer lifespan; intelligent services such as supporting life prediction reduce downtime losses.
