Preassembling of hot stove bricks & furnace construction

Preserving various hot stove refractories like the CRINON series and others in its product lines, Krosaki Harima Corporation carefully selects and recommends the most appropriate materials for hot stove linings in consideration of local conditions, including temperatures.

A product example

CRINON S-21, high quality silica brick, excellent in creep resistance, is recommended for application in hot stove domes or checker bricks employed in relatively high temperature zones.
CRINON series 140 to 155, high quality mullite bricks, is optionally recommendable in consideration of the local service temperatures.
Clay bricks of SF-115 up to -125 are employed in relatively lower temperature zones.
H1MF and COMF15, which are high alumina bricks with excellent spalling resistance, were developed as bricks for the burner portion, and have high thermal shock resistance and high mechanical strength.

Implementation of careful preassembling

Recently the operational conditions of hot stoves have become more severe in terms of both higher temperatures and also blast pressures. The behavior of hot stove refractories at the higher operational temperatures is considered significantly important and therefore, not only appropriate material selection but also precise and careful construction work are essential in furnace engineering. To fulfill these requirements, Krosaki Harima Corporation implements careful preassembly of respective major portions of the furnace.
