我公司冶炼厂的转炉为50吨的。吹炼的冰铜品位一般为20～25％。无产阶级文化大革命以来,我们对炉子结构,包括烟道系统进行了一定的技术改造,在吹炼过程中对提高粗铜质量、提高冷料比和配合制酸等方面也做了一定工作。 (一) 炉子结构的改进 改造前后主要尺寸列于附表。 在学习了兄弟单位加长炉体、加大炉口的先进经验之后,为了减轻炉后劳动强度,给实现机械化捅风眼创造条件,提出了进一步加大风口内径,减少风口数目的建议。送风口内径从原设计的38毫米
My company smelter converter for 50 tons. The matte ice grade is generally 20 ~ 25%. Since the Great Proletarian Cultural Revolution, we have carried out some technological transformations on the structure of the furnace, including the flue system, and have also done some work in improving the quality of blister copper, increasing the ratio of cold-to-medium material and acid-forming in the process of blowing. (A) the improvement of the furnace structure The main dimensions before and after transformation listed in the table. After learning the advanced experience of the brother unit in lengthening the furnace body and enlarging the mouth of the furnace, in order to reduce the labor intensity of the furnace and create the conditions for mechanization to poke the eye of the eye, suggestions were made to further increase the diameter of the tuyere and reduce the number of tuyeres. Outlet diameter 38 mm from the original design
