Abstract

This Master's Thesis deals with the strength assessment and thermal analysis of ingot tongs with a load capacity of 25,000 kg, designed for handling loads at temperatures up to 1,100 °C. The objective of the thesis is to perform a comprehensive structural analysis with an emphasis on verifying the safety and operational reliability of the design, including a comparison of the suitability of S355 and S690QL steels for the load-bearing frame of the tongs. The thesis structure includes a heat transfer analysis considering radiation, an analytical check of the pins, and a detailed FE analysis of the entire tongs structure applying temperature-dependent material properties in compliance with basic safety standards. The structural design of the tongs is documented in the appendices of the thesis.
