Application Data of HARVEST-ML Stainless Steel Fibre
The properties and performance of refractory materials applying to various beating furnaces kilns and coke ovens should be greatly improved if SSF will be mixed with.
Today SSF reinforcement is finding its way into every parts of modern industries.
They can be concluded as following:
1) Metallurgical Industry
Blast- heating cupola , iron smelting furnaces , open hearth furnaces,
Convertors, electrical furnaces, spray gun for refining of metal out of furnace, sintering furnaces and kilns . Heaters for steel rolling , including lining, furnace door and wrapping covers around water cycling pipes.
2) Oil oven , and kilns.
3) Furnaces and kilns in ceramic, glass and enamel industries.
4) Rotary and standing kilns in cement industry.
5) Forging heaters and boilers for power plant.
6) Furnaces and kilns in other industries.
