The burner brick is a key refractory component in industrial kiln combustion systems, specifically designed to protect the burner and optimize the combustion process. Our burner bricks, produced by Shandong Luming, are manufactured using high-quality bauxite or fireclay as the main raw materials, formed under high pressure and fired at high temperatures. The product features precise geometry, excellent thermal shock stability, and high strength. It can withstand direct flame impingement and high-temperature gas flow erosion, ensuring stable flame shape and uniform temperature, thereby improving combustion efficiency and extending burner service life.
01
Excellent High-Temperature Resistance
Refractoriness up to 1750°C, with a long-term service temperature range of 1300°C - 1550°C, suitable for high-temperature environments in various industrial kilns.
02
Outstanding Thermal Shock Stability
Dense structure resists thermal stress caused by rapid temperature changes, reducing cracking and spalling, leading to a long service life.
03
High Strength and Abrasion Resistance
High-pressure forming and high-temperature firing processes give the product high cold crushing strength and resistance to erosion and abrasion from high-speed flames and dust.
04
Precise Dimensions and Shape
As a precision special-shaped brick, we strictly adhere to customer drawings for production, ensuring accurate dimensions and complex shapes for a perfect match with the burner and optimal combustion performance.
