一般情况 矿务局的铅冶炼厂建于1938年,虽几经改、扩建,但迄今其工艺流程仍沿用古老的烧结锅,即将铅精矿烧结脱硫,然后加入焦炭及铁屑,经鼓风炉还原熔炼成粗铅。直接从事铅冶炼作业的约400人。每年十月初开始生产,到翌年5月停炉,6至9月为检修期。 烧结锅与鼓风炉均为压风与抽风联合,炉内形成负压,在正常情况下,烟尘不致外逸。各操作台设有吸尘装置,废气经过冷却
General Bureau of lead mining smelter was built in 1938, although several changes, expansion, but so far its process is still using the ancient sintering pot, about to sinter the desulfurization of lead concentrate, and then add coke and iron filings, reduction furnace smelting Into a rough lead. Directly engaged in lead smelting operations of about 400 people. Production begins in early October each year, and shutdown is scheduled to take place in May the following year. From June to September, it is a maintenance phase. Sintering pot and blast furnace are combined pressure and ventilation, the furnace negative pressure, under normal circumstances, smoke and dust will not escape. Each operating station has a vacuum cleaner, the exhaust after cooling
