山西传统坩埚炼铁技术类型、分布及其形成原因

Types,Distribution and Forming Cause of Crucible Smelting

山西传统坩埚炼铁技术可分为两种类型:一步法和两步法,每种类型又包含多种不同的方法。一步法主要集中在太行山南段,两步法主要分布于太行山中段。形成两种类型的主要原因是各地不同的资源特征,矿石品位低且还原性好、还原剂含硫量低的地区采用一步法;矿石品位高且还原性差,还原剂硫含量高的地方采用两步法。

Literature, surveys and interviews show that crucible smelting can be divided into two types： one -step and two - step smeltings. The former is by smelting the ore in the crucible of the reduction of iron and iron slag is separated better. The latter is the reduction of the ore in different crucibles, in which iron and slag are separated basically. The first method is mainly carried out in the southern section of the Taihang Mountains, and the second in the central section of the mountains. The two different methods are used mainly because of the different resource characteristics and the traditional technology in different regions. In the region with low iron content and low sulfur content, the first method is used and in the area with high - grade ore whose quality is poor, and whose sulfur con- tent is high, the second is used.
