我们反射炉车间,自从在反射炉内安装了二次空气鼓风设备以后,由于二次空气的利用能符合于炉内的燃烧条件,在1955年度里屡次地出现了过去所没有的成绩。如过去熔炼一炉铜需要29～30小时,现在逐步缩短到26小时、24小时、以至只要22小时50分钟的时间就可以炼出一炉铜。在加料数量方面,由原来只加入50吨,渐次地增加到65吨。加入冷铜的熔化时间也从每炉6小时的基础上缩短到2小时50分钟。由于熔炼时间的缩短、产量的增加,不仅使燃料、耐火材料的消耗定额降低,而且更大大地提高了劳动生产率。
Since our reverberatory furnace plant, since the secondary air blower was installed inside the reverberatory furnace, secondary combustion air was used to meet the combustion conditions in the furnace. In 1955, there were many times that we had not achieved before. If in the past melting a furnace of copper takes 29 to 30 hours, and now gradually reduced to 26 hours, 24 hours, as long as 22 hours and 50 minutes can be a furnace of copper. In the feeding amount, from the original only added 50 tons, gradually increased to 65 tons. The melting time for adding cold copper is also shortened from 6 hours per furnace to 2 hours and 50 minutes. Due to the shortening of melting time and the increase of output, not only the consumption quotas of fuels and refractory materials are reduced, but also the labor productivity is greatly increased.
