Fireclay bricks - TRISAM
Fireclay bricks TRISAM are produced on the base of the top quality calcinated fireclay, refractory clays and kaolins.
Two different technological processes – dry and semi-dry pressing are applied for the manufacturing.
This is carried out on computer controlled production lines.
These are intended above all for the consumption in the metallurgical industry. There they are used for the linings of hot-blast stoves, blast furnaces, ladles, stopper rods, hollow-ware, ceramic recuperators, heating furnaces etc. Furthermore these products are used in the ceramic and chemical industries and other branches where application of refractory materials is needed.
