SK32 firebrick is a widely used cost-effective refractory fire brick designed for diverse industrial high-temperature environments. With stable chemical composition containing 35%-38% alumina, this refractory brick features a refractoriness of up to 1620°C, meeting the standard high-temperature resistance requirements of most industrial kilns and furnaces. Its scientific physical structure brings reliable and durable performance for long-term industrial operation, making it a staple in the refractory material industry.
It delivers excellent thermal shock resistance, effectively resisting frequent temperature rises and falls without cracking or peeling, which greatly reduces equipment maintenance risks.
Equipped with low thermal conductivity and stable volume stability under continuous high heat, it minimizes heat loss and maintains structural integrity.
Additionally, SK32 firebrick shows strong resistance to acidic slag and high-temperature gas corrosion, with moderate porosity and stable mechanical strength to withstand mechanical extrusion and abrasion in harsh working conditions.
It features simple installation and excellent adaptability, fitting standard industrial sizes (230×114×65mm) and customizable specifications to suit different furnace structures.
With low permanent linear change after repeated heating, it ensures long service life and stable operation of industrial equipment, effectively cutting replacement and maintenance costs for enterprises.
Its stable physical and chemical properties also enable consistent performance in long-cycle industrial production.
It is commonly used for lining metallurgical furnaces, blast furnaces and hot blast stoves in the metal industry.
In the cement and glass manufacturing sector, it serves as the lining of rotary kilns, preheaters and glass melting furnaces.
It also applies to tunnel kilns, shuttle kilns in ceramic production, as well as boiler linings and reaction equipment linings in petrochemical, power generation and waste incineration industries.
We provide standard and customized refractory bricks with strict quality inspection, stable batch performance and competitive factory prices. Whether you need bulk orders or technical parameter consultation, our professional team offers one-stop solutions.
