专利号:86209520 辊底式加热炉用于钢板、钢管、型钢和线材的退火、调质、淬火和回火处理。其炉辊在550～1150℃的高温下托着被加热钢件进行转动,推进工件进行热处理。在现有辊底式加热炉中,炉辊的形式有耐热钢空腹炉辊,带水冷通轴的耐热钢炉辊或带水冷通轴的碳化硅作辊套的炉辊。这些炉辊存在的主要缺点是:造价昂贵,冷却水带走的热量大。增强耐火浇注料炉辊与现有技术相比,
Patent No .: 86209520 roller hearth furnace for steel, steel, steel and wire annealing, quenching, quenching and tempering. The furnace roller at 550 ~ 1150 ℃ high temperature supported by the heated steel rotation, promote the workpiece for heat treatment. In existing roll hearth furnaces, the furnace rolls are in the form of heat-resistant steel idler rolls, heat-resistant steel rolls with water-cooled through-rolls or silicon carbide roll rolls with water-cooled through-rolls. The main disadvantages of these rollers are: expensive, cooling water to take away the heat. Enhanced refractory castable roller furnace compared with the prior art,
