Expansion of Technical Renovation in the Metallurgical Industry: Wear-resistant Ceramic Valves Widely Adopted in Blast Furnace Coal Injection and Water Slag Treatment Systems

Expansion of metallurgical technical renovation: wear-resistant ceramic valves widely applied in blast furnace coal injection & water slag treatment systems

Steel mills across the country launched energy-saving technical upgrades and capacity replacement projects, with concentrated construction of pipeline renovation works for blast furnace pulverized coal injection, slag flushing and sintering dust removal systems. Pipeline media contains massive hard mineral particles that cause frequent seal failure and production shutdown maintenance under long-term erosion. At present, multiple domestic steel plants purchase ceramic ash removal ball valves and ceramic slag lock valves in bulk. Benefiting from the high hardness and anti-scour property of ceramics, equipment maintenance cycles are extended by 2 to 3 times, effectively reducing losses caused by production halts. Wear-resistant special valves have become essential supporting products for metallurgical technical transformation.
