Production Details
Xintai Refractory manufactures High Temperature Acid Resistant Bricks using a carefully selected blend of high-quality iron-rich clays and refractory minerals. The production process involves precise raw material grinding, homogenization, and molding under high pressure to achieve optimal density and mechanical strength.
The bricks are then subjected to controlled high-temperature firing in tunnel kilns, reaching temperatures up to 1400°C. This firing process ensures the development of a dense, uniform microstructure that provides excellent resistance to acid corrosion and thermal stress.
Packing and Shipping Details
Carefully packed in wooden pallets with plastic film wrapping
Optional fumigation and seaworthy packaging for export
Global delivery with customized logistics solutions
