self-releasing slag

It is practicable to smelt sulfate titania slag in open furnace that traditionally used for producing chloride slag by self-baking electrode, and preferable quality titania slag and good economic target can be obtained.

结果表明：（1）采用传统的生产氯化渣的自焙电极的敞口电炉，冶炼酸溶性钛渣是可行的，获得了较好的钛渣质量和技术经济指标。

Study on self-shielded flux-cored wire with high baf_2 slag system

高BaF2渣系自保护药芯焊丝的研究

During this subject research the author mainly investigate and examine the self-shielded mechanism base on mix metal powder such as C-Mn-Si or C-Al-Si, which without fluoride and produce little slag and fume during welding.

笔者在本课题研究中着重论证并考察了C-Mn-Si与C-Al-Si等不含氟化物主要依靠合金元素实现的非造渣型自保护机制。

Reducing content of hydrogen effect of fluoride, carbonate, active chide and rare earth oxide in weld by self-shielded flux-cored wire with CaF2-TiO2 MgO slag system is investigated.

探讨氟化物、大理石、高价氧化物和稀土氧化物在氟钙钛渣系自保护药芯焊丝中的降氢机理。

By self-made static testing device of common micro-electrolysis, a group of static experiments were designed and fulfilled based on the four factors: volume ratio of iron slag and coke, optimum pH value setting under the acid and alkaline conditions, and optimum reaction period.

利用自制的普通微电解静态试验装置，以废铁屑与焦炭用量比，调溶液酸、碱pH值和反应时间4个因素设计进行了一组静态试验。
