气垫式(浮动式)退火炉是把退火材料(主要是带材)被热风喷吹悬浮在炉内,而不接触炉内结构部件的一种高速连续退火炉。据报导:日本“大同制钢”两年前建造了第一台卧式气垫退火炉;利用这种炉子可得到机械性能和物理性能均匀的,结晶粒度小的,表面无划伤的退火材料,炉子加热和冷却能力大,占地面积小,今后,将随着炉子使用的热风循环鼓风机耐热能力的提高,也可应用在钢铁生产方面上去。 The air-cushion (floating) annealing furnace is a high-speed continuous annealing furnace in which the annealing material (mainly the tape) is suspended by the hot air in a furnace without contacting the structural components of the furnace. It is reported that Japan’s “Datong Steel” built the first horizontal air cushion annealing furnace two years ago; the use of such furnace can be obtained mechanical properties and physical properties of uniform, small grain size, scratch-free surface of the annealed material, Furnace heating and cooling capacity, small footprint, the future, with the stove used in hot air circulation blower heat capacity improvement can also be applied in the steel production up.
