Loading Decrease in Metallurgical Machines

Abstract

The study shows that it is necessary to know running quality (that is load-deflection curve) in order to estimate load degree on machines power lines. Running qualities are limited on the maximal loads (durability). It should be also known the impact parameter points (energy or deformation). Their superposition on the running quality allows determining generated loads degree in machine power line. It is possible to decrease the generated loads to the safest level by changing power line running quality with the help of dynamic spare parts. The type of machine security system depends on drive line data quality K: using shock-absorber preventer, arresting device preventer or a combination of the both.

Analysis of stress-strain states of casting crane traverse

“…Force F2 that acts during acceleration / deceleration. It acts in horizontal plane [2]; When crane moves with acceleration load is deflected at angle φ due to action of horizontal force [6]:…”

“…Their elements are exposed to significant dynamic loads and high temperatures. Need to develop a methodology for strength calculations of traverse elements of casting cranes was justified earlier [1][2][3][4][5] that would allow to: consider their actual working conditions, increase accuracy of calculations, increase their reliability and safety of operation. It was shown [6] that actual values of inertial loads during crane moving may exceed values considering during its design.…”

Adapters for metallurgical equipment

“…These loads can be technological and nontechnological. Many times non-technological loads are causes of accidental breakdowns or increased wear of expensive parts of metallurgical equipment [1][2][3][4][5][6].…”

Device for Making Horizontal Wedge Thrust of Rolling Stand

“…Especially big alternating loads are on reversing rolling stands [1]. Dynamics of rolling stands can result in their expensive accidental breakdowns [2][3][4]. In addition, dynamics results in plastic deformation of housings windows, facing strips, lining straps and chocks [5,6].…”
