火法冶金过程中,溫度是一切工作的基础。对鋅横罐汽餾来說,蒸餾过程是在一个个的单体蒸餾罐中进行的。在这样一个装有数百个蒸餾罐的炉內,要使每个罐都能經受同样的溫度是非常不容易的,但却是非常必要的。为此結合生产实践,我們进行了大量的热工研究工作,改进了設备結构和提高了管理水平,因而使生产水平在旧有的設备条件下得到了很大的提高。如鋅蒸餾实收率保持在92.0％以上,有时达到94.5％,超过了国外的先进水平。一、蒸餾炉的结构平罐蒸餾炉具有两个很大的、彼此連通的燃烧室,它有长的燃烧带和寬的燃烧面。为了使每个蒸餾罐都能經受相同或溫差較小的温度,要求燃烧气体应
Pyrometallurgical process, the temperature is the basis of all work. For zinc canisters, the distillation is carried out in individual canisters. In such a furnace with hundreds of distillation pots, it is not easy to get the same temperature for each tank, but it is very necessary. Therefore, in combination with the production practice, we conducted a lot of thermal engineering research, improved the equipment structure and improved the management level, so that the production level has been greatly improved under the old equipment conditions. For example, the recovery rate of zinc distillation remained above 92.0%, sometimes reaching 94.5%, exceeding the advanced level of foreign countries. First, the structure of the distillation furnace Flat tank distillation furnace has two large, interconnected combustion chamber, it has a long combustion zone and a wide combustion surface. In order for each distillation tank to withstand the same or less temperature difference, the combustion gas should be required
