Abstract
The movement model of self-adjusting bolt is built in this paper, then the kinematical and mechanical analysis is taken to determine the movement of bolt under the converters working condition.Via the mechanical model analysis of self-adjusting bolts, the load applied to the self-adjusting bolt support including the static weight load of converter and steel liquid, the tilting torque, the dynamic load produced by frequent startup, brake, impact, and the boiling of steel liquid is calculated to determine the distribution of load forcing on the three groups of the self-adjusting bolt. According to the results of stress analysis, the bolt facing tapping hole is the most dangerous when converter tilts 63°. The maximum torque is 281.5101tm.
