Sažetak

In this paper, the transient temperature field and thermal stress of the slagging-off robot arm were analyzed by finite element method, the temperature distribution and change of the robot arm in one working cycle were determined, and the thermal stress and thermal deformation of the slag-scraping plate after the skimming was completed were solved. The results show that the temperature of the equipment in the slagging-off process can reach 206 °C, and the heat can be transferred to the position of 200mm, which will not affect the key parts in the manipulator. Due to the direct contact with molten iron, the heat stress and deformation of the slag-scraping plate are large, which may result in the high melt loss rate of the slag-scraping plate.
