Refractory Tapping Spout for EAF is a high-performance precast refractory component specially designed for the tapping area of electric arc furnaces (EAF). It is installed at the furnace tapping outlet to guide molten steel flow during the steelmaking process while protecting the furnace structure from severe thermal and chemical damage.
Manufactured using high-quality high alumina refractory materials, alumina-magnesia compositions, or customized refractory castables, the EAF tapping spout provides excellent resistance to molten steel erosion, slag corrosion, thermal shock, and mechanical impact.
During electric arc furnace tapping operations, the refractory tapping spout is exposed to extremely high temperatures, rapid temperature fluctuations, and continuous contact with molten steel and slag. Xintai’s EAF refractory tapping spouts are developed with optimized material formulations and precision manufacturing technology to ensure stable steel flow, reduced refractory consumption, and extended service life.
As a professional refractory manufacturer, Xintai provides custom refractory tapping spouts for EAF furnaces according to furnace capacity, tapping angle, installation position, and operating conditions, helping steel plants improve production efficiency and reduce maintenance costs.

Product Features
- Excellent High Temperature Resistance: The EAF tapping spout refractory is designed to withstand continuous exposure to extreme temperatures during steel tapping. High alumina content and optimized refractory structure maintain excellent stability under high-temperature conditions.
- Superior Thermal Shock Resistance: Electric arc furnace tapping involves frequent heating and cooling cycles. The specially formulated refractory material provides excellent resistance against thermal shock, cracking, and spalling.
- Strong Molten Steel and Slag Corrosion Resistance: The dense refractory structure effectively reduces penetration from molten steel and aggressive slag, improving the durability of the tapping channel and reducing replacement frequency.
- High Mechanical Strength: With high cold crushing strength and wear resistance, the refractory tapping spout for steel furnace can withstand mechanical impact, vibration, and continuous operation in harsh steelmaking environments.
- Customized Design and Manufacturing: Each custom EAF refractory tapping spout is manufactured according to customer drawings, furnace specifications, tapping hole dimensions, and installation requirements to ensure accurate fitting.
- Extended Service Life: Optimized raw materials, advanced production technology, and strict quality control help improve refractory performance and reduce furnace downtime.
