隔绝热源是降低加热炉和热工件散发出来辐射热的措施之一。 隔热的简单措施是,把能动的小型加热炉移到车间外边,出料口通过墙壁通向工作地点,并加装隔热板。对无法移动的大型加热炉,可以在四周筑一道砖墙,墙与炉之间留一定的空隙,形成空气隔热层,效果很好。有的单位测定,未筑墙 Isolating heat sources is one of the measures to reduce radiant heat emitted by furnaces and hot workpieces. The simple measure of heat insulation is to move the small movable heating furnace to the outside of the workshop, through the wall to the work place and to install the heat insulation board. For large furnaces that can not be moved, a brick wall can be built around, leaving some space between the wall and the furnace to form an air-insulated layer with good effect. Some units measured, no walls
