摘要
顶枪是RH炉外精炼装备中的重要设备,在冶炼超低碳钢的作用尤为重要,本文从制造工艺的角度出发,根据拉瓦尔孔型的顶枪结构特点,选择紫铜做为枪头材料,并制订详细的异种金属焊接工艺,严格的质量检验,获得批量制造的成功经验,为实现顶枪的冶炼工艺和国产化奠定了坚实的基础。
Top lance is important equipment in RH refining. It has particularly very important role in ultra - low carbon steel smehing. From the perspective of the manufacturing process, the copper is selected as the lance head material according to the structure and characteristics of Lava/top lance. Dissimilar metal welding process is developed and strict quality inspection is implemented, which finally obtained successful experience. It established solid foundation to achieve the top lance smelting technology and localization.
