目前一些炼铜厂吹炼冰铜还广泛采用小型转炉。我厂有三台直径2米的卧式转炉,具有13个风眼,风眼直径为38毫米。所用风机为八级离心式,其风压为1(公斤/厘米~2),风量为80(米~3/分)。砌炉时间每次大修约7天,小修约3天。我厂小转炉寿命较低,去年上半年,每次大修后的炉衬,经45～60炉次便需要进行小修,经常只能勉强维持两台炉子生产,严重影响到生产任务的完成。因此,提高小转
At present, some smelting copper smelting also widely used small converter. My factory has three horizontal 2 meters in diameter converter, with 13 eyes, eye diameter of 38 mm. The fan used for the eight centrifugal, the wind pressure of 1 (kg / cm ~ 2), the air volume of 80 (m ~ 3 / min). Grate furnace time each overhaul about 7 days, minor repair about 3 days. In the first half of last year, the furnace lining after each overhaul required a minor repair after 45 to 60 heats, and often only barely maintained the production of two furnaces, seriously affecting the completion of production tasks. Therefore, improve the small turn
