изоляционные огнеупорный кирпич TK23 TK26-TK28-TK30-TK3000-

TK Insulating Firebrick is made from high purity refractory clays and other raw materials, with light weight and mini-porosity well distributed. Each brick is machined to precise tolerances on all six faces. Characteristic: - Low thermal conductivity - Low heat storage - High spalling resistance - High hot compressive strength - Low iron oxide and alkali flux content - Accurate dimensions Application: - Hot face refractory lining for furnaces, kilns, flues, refining vessels and heaters, regenerators, gas producers and similar high temperature industrial equipment. - Back up insulation for furnaces, kilns and similar high temperature industrial equipment.
