四、模拟试验由于烟囱内衬喷涂施工国内尚缺乏经验,我们仅初次施工,因此,为了保证工程质量,在冶金部建研院内试验的基础上,根据已到的工程材料与现场实际情况,我们在施工前进行了一次现场模拟试验。 1.试验时间:1983年9月12日至27日共16天。 2.试验地点:烧结厂200米钢烟囱附近。 3.试验方法:采用模拟试验法。事先制成一个圆铁筒,壁厚8毫米,直径5米,高1.8米,筒内刷漆并设L形锚固件、钢筋网等,规格大小均与原设计相同,最后喷涂砼内衬。 4.喷涂材料:水泥为江南水泥厂生产的“出口纯”硅酸盐水泥;骨料为山东王村耐火材料厂生产的陶粒、叶腊石、耐酸粉袋装
IV. Simulation Test Since the chimney lining spraying construction industry is still inexperienced in our country, we only started the construction for the first time. Therefore, in order to guarantee the quality of the project, based on the experiments conducted by the Ministry of Metallurgical Industry and Construction Research Institute, based on the actual engineering materials and actual conditions at the site, we An on-site simulation test was conducted before construction. 1. Test time: 16 days from September 12 to 27, 1983. 2. Test site: Sintering plant 200 meters near the steel chimney. 3. Test method: The simulation test method was used. A round iron cylinder was made in advance, with a wall thickness of 8 mm, a diameter of 5 meters, and a height of 1.8 meters. The cylinder was painted and set with L-shaped anchors, reinforced mesh, etc. The dimensions were the same as those of the original design, and the lining was finally sprayed. 4. Spraying material: cement is “export pure” Portland cement produced by Jiangnan Cement Plant; aggregate is made of ceramics, pyrophyllite and acid-proof powder bags produced by Shandong Wangcun Refractory Material Factory.
