Bulk Density 3.3-3.8gcm3 High Alumina Refractory Bricks SK36 Kilns Ideal for Thermal Insulation and Durable Heat Resistant Structures

Product Description:

The High Alumina Refractory Bricks, specifically the SK-36 type, represent an advanced solution for high-temperature industrial applications. Engineered to withstand extreme thermal environments, these bricks boast a remarkable Refractoriness Under Load (RUL) of ≥1700℃, making them ideal for use in high temperature industrial furnaces, kilns, and other similar equipment. Their exceptional thermal stability ensures that they maintain structural integrity and performance even under prolonged exposure to intense heat.

One of the standout features of the SK-36 High Alumina Refractory Bricks is their impressive Cold Crushing Strength of ≥120MPa. This high mechanical strength guarantees durability and resistance to mechanical stresses, which are common in industrial settings where aggressive thermal cycling and heavy loads are prevalent. The combination of high RUL and cold crushing strength ensures that these bricks provide both thermal and mechanical reliability, reducing maintenance costs and downtime.

The bulk density of these bricks ranges between 3.3 to 3.8 g/cm³, a specification that reflects their dense and compact microstructure. This density contributes to their excellent thermal conductivity and resistance to slag penetration, which are critical factors in enhancing the lifespan of refractory linings. The dense composition also helps in minimizing wear and erosion caused by chemical attack and abrasive materials within furnaces and kilns.

High Alumina Refractory Bricks of the SK-36 type are often compared to Alumina-Chrome-Zr brick materials due to their similar high-performance characteristics. While Alumina-Chrome-Zr bricks are renowned for their enhanced resistance to corrosion and thermal shock thanks to the inclusion of chromia and zirconia, SK-36 bricks offer a balanced combination of alumina content and mechanical strength suitable for a wide range of industrial applications. In environments where chemical aggressiveness and thermal fluctuations are intense, Alumina-Chrome-Zr bricks may be preferred, but SK-36 bricks remain highly competitive due to their cost-effectiveness and robust performance.

These bricks are widely used in the construction and maintenance of high temperature industrial furnaces and kilns across various industries such as metallurgy, cement production, glass manufacturing, and petrochemical processing. Their ability to withstand temperatures above 1700℃ makes them particularly valuable in industries that require reliable refractory linings to maintain energy efficiency and process stability. Furthermore, the SK-36 bricks’ resistance to thermal shock reduces the risk of cracking and failure during rapid temperature changes, ensuring operational safety and longevity.

In summary, the SK-36 High Alumina Refractory Bricks provide a superior solution for demanding high-temperature industrial environments. Their key attributes—including a RUL of ≥1700℃, cold crushing strength ≥120MPa, and bulk density between 3.3 and 3.8 g/cm³—make them a robust choice for furnace and kiln linings. Although they share some performance traits with Alumina-Chrome-Zr brick varieties, SK-36 bricks offer an excellent balance of thermal resistance, mechanical strength, and cost-efficiency. Industries seeking durable, high-performance refractory materials will find the High Alumina Refractory Bricks SK-36 to be a reliable and effective option for enhancing furnace longevity and operational efficiency.
