针对J507焊条TiO2CaOSiO2CaF2渣系,进行了药皮渣系及合金系统对焊条发尘量和工艺性能影响的研究,认为在保证焊接工艺性能基础上,适当提高TiO2和铁粉含量,降低CaF2含量,同时加入硅钙合金,可以获得较低的焊条发尘量。研制出的J507DF焊条发尘量为9.13g/kg,焊接工艺性能优良,其他技术指标满足国家标准要求。 Aiming at the TiO2CaOSiO2CaF2 slag system of J507 electrode, the effects of the slag system and the alloy system on the dust emission and the process performance of the electrode were studied. It is considered that the content of TiO2 and iron should be properly increased and the CaF2 content should be reduced while ensuring the welding process performance. Add silicon calcium alloy, you can get a lower electrode dust. Developed J507DF electrode dust volume 9.13g / kg, excellent welding performance, and other technical indicators to meet the national standards.
