Classification of anchor refractory bricks

Anchor refractory bricks are a special material widely used in high-temperature industrial furnaces to support and fix the refractory lining structure. Due to its unique design, anchor bricks can effectively improve the strength and stability of the refractory lining and extend the service life of the equipment. This article will introduce in detail the classification of refractory anchor bricks and their specific applications in industry.

Classification of anchor refractory bricks

High alumina anchor brick

Raw Materials: High alumina bauxite is the main raw material, and the alumina content is usually above 48%.
คุณสมบัติ: It has good high-temperature resistance and corrosion resistance, and is widely used in the steel industry and cement kilns.
แอปพลิเคชัน: Used in areas where high strength and wear resistance are required in high-temperature kilns.

Clay anchor bricks

Raw materials: Refractory clay is the main raw material, with relatively low alumina content.
คุณสมบัติ: High-cost performance, suitable for medium-temperature kilns or low-heat load areas.
แอปพลิเคชัน: Applied to lining fixation of small and medium-sized kilns.

Corundum anchor brick

Raw materials: fused corundum or sintered corundum as the main raw materials, with an alumina content of more than 90%.
คุณสมบัติ: extremely strong corrosion resistance and wear resistance, excellent temperature resistance.
แอปพลิเคชัน: used in high-temperature industrial kilns that require extremely high-temperature resistance and corrosion resistance.

Silicon carbide anchor brick

Raw materials: Silicon carbide is the main component, usually with some binder added.
คุณสมบัติ: ทนต่อการสึกหรอได้ดี, excellent thermal conductivity, ทนต่อแรงกระแทกจากความร้อนได้ดีเยี่ยม.
แอปพลิเคชัน: Suitable for cooling areas of high-temperature kilns and areas that require rapid heat dissipation.
