鞍钢工业炉窑烟囱(以下简称烟囱)有很大一部分是日伪遗留的,而且绝大部分是钢筋混凝土烟囱;另一部分是在1952年以后建造的,有砖的,钢筋混凝土的和钢外壳的。日伪遗留的烟囱普遍地使用了空气隔热层。其中一部分在混凝土筒壁的离地很近处,以及筒壁中、上部留有通气孔洞,一部分则不留孔洞。内衬多系从基础底板一直到顶,并分段改变厚度。空气隔热层的厚度在底部为100～165毫米不等;但到中部或上部
An important part of Anshan Iron and Steel Industrial Furnace Chimney (hereinafter referred to as the chimney) is left by the Japanese and Puppet Army, and most of them are reinforced concrete chimneys; the other part is built after 1952, with brick, reinforced concrete and steel shells. . The chimneys left behind by Japanese and Puppets generally use air insulation. Some of them are in close proximity to the concrete wall and there are ventilation holes in the middle and upper part of the wall, and some do not leave holes. The lining mostly extends from the base floor to the top, and changes the thickness step by step. The thickness of the air insulation layer varies from 100 to 165 mm at the bottom; but to the middle or upper
