Abstract A welding flux containing silicomanganese slag with a flux additive based on dust taken from gas cleaning facilities of aluminum industry has been studied. The following has been studied: the effect of a carbon-and-fluorine-containing additive exerted on the content of total oxygen and hydrogen in the welding seam’s metal, as well as on the impact strength in the positive and negative temperature range. To make the welding flux, silicomanganese slag produced by the West Siberian Electrometallurgical Plant has been used as a base. Also, a flux additive has been used to make carbon-and-fluorine containing dust taken from the electrostatic precipitators of RUSAL’s aluminum-producing enterprises. The samples have been welded using an ASAW-1250 welding tractor. The chemical composition of the welded samples under study has been determined according to GOST (State Standard) 10543–98 by means of an atomic emission technique using a DFS-71 spectrometer and by means of means of an X-ray fluorescence technique using an XRF-1800 spectrometer. Fractional gas analysis has been performed using a LECO TC-600 analyzer. The welded samples have been tested for impact strength in the positive and negative temperature range using a pendulum impact testing machine according to GOST (State Standard) 9454–78. Upon using a carbon-and-fluorine-containing flux additive in the welding flux based on silicomanganese slag, the amount of oxygen and hydrogen in the welding seam’s metal exhibits a decrease. At the same time, the impact strength in the positive and negative temperature range exhibits an increase. The curves for the amount of oxygen and hydrogen in the welding seam’s metal, as well as for the impact strength depending on the introduced amount of carbon-and-fluorine-containing flux additive, are plotted.

碳氟对硅锰渣熔剂的影响

摘要 研究了一种基于铝工业气体净化设施粉尘的含硅锰渣焊剂和助焊剂添加剂。研究了以下内容：含碳氟添加剂对焊缝金属中总氧和氢含量的影响，以及对正负温度范围内的冲击强度的影响。为了制造焊剂，西西伯利亚电冶金厂生产的硅锰渣已被用作基础。此外，还使用助焊剂添加剂来制造来自俄铝铝生产企业静电除尘器的含碳氟粉尘。样品已使用 ASAW-1250 焊接拖拉机焊接。所研究的焊接样品的化学成分已根据 GOST（国家标准）10543-98 通过使用 DFS-71 光谱仪的原子发射技术和使用 XRF 的 X 射线荧光技术确定-1800 光谱仪。使用 LECO TC-600 分析仪进行了气体分馏分析。根据 GOST（国家标准）9454-78，使用摆锤冲击试验机对焊接样品进行了正负温度范围内的冲击强度测试。在基于硅锰渣的焊剂中使用含碳和氟的焊剂添加剂后，焊缝金属中的氧和氢量表现出减少。同时，在正负温度范围内的冲击强度呈现增加。
