skull furnace

The copper crucible for 25 kg vacuum skull furnace is systematically studied. The various factors effecting on the copper crucible failure are analyzed and discussed. The effective methods of elongating the service life of the copper crucible is indicated.

对25kg真空凝壳炉用紫铜坩埚进行了系统研究，分析和讨论了影响紫铜坩埚损坏的各种因素，提出了延长紫铜坩埚寿命和提高坩埚利用率的有效方法。

The Study on the Copper Crucible of 25 kg Vacuum Skull Furnace

25kg真空凝壳炉用紫铜坩埚的研究

From the practice, the material skull and the main problems for reacting furnace are analyzed and studied, then the paper presents the modification.

本文从生产实际出发，对反应炉的主要故障“物料结壳”进行了认真分析和研究，并实施了改造。

The results show that the vulnerable zone of lining refractory and formation zone of slag skull are in a 100 mm range on lining's inner surface from the middle/ lower part of furnace stack and bosh to the front-end of cooling plate.

结果表明，在炉身中下部和炉腹、炉腰部位炉衬内表面到冷却板前端的100mm范围内是炉衬耐材易损区和渣皮形成区；

In order to make the hearth and hearth bottom have the same life-span as that of blast furnace, one of effective measures is to form a layer of slag-metal skull on the hearth and hearth bottom.

实现高炉炉缸、炉底与高炉寿命同步的措施之一就是在高炉炉缸和炉底冻结一层渣铁壳。
