The Induction-Furnace 160 kg is used for the castings of ingots up to 100 kg and steel/slag experiments. The raw materials consist of pure iron or remelted steels. Analytical measurements of the current composition allow the adjustment of the alloying element contents very accurate. Thus it is able to produce numerous steel grades or [...]
The Induction-Furnace 20 kg is used for the castings of small ingots, specific experiments related to continuous casting (IMC-B and SSCT Test) and steel/slag experiments. The raw materials consist of pure iron or remelted steels. Analytical measurements of the current composition allow the adjustment of the alloying element contents very accurate. Thus it is [...]
The In-Situ Material Characterisation – Bending (IMC-B) Test is a method for the investigation of the susceptibility to surface crack formation under continuous casting conditions. It is possible to investigate significant influencing factors and casting parameters, e.g. different cooling strategies and casting speeds. It allows the characterisation of critical strains values for the formation [...]
The Submerged-Split-Chill-Tensile (SSCT) machine was originally developed at EPF Lausanne in 1985 and is used for in-situ characterization of strength and hot tearing sensitivity of steel during solidification. An additional in-house simulation software enables the coupled numerical calculation of solidification progress and hot tearing formation in the experiment. Principles and advantages of SSCT-machine: The [...]
The Chair of Metallurgy gratulate Dipl.-Ing. Hans-Jörg BAUMGARTNER, Dipl.-Ing. Tong LI, Dipl.-Ing. Markus MAUNZ (with honors), Dipl.-Ing. Michael WENGER and Dipl.-Ing. Felix ZECHLING for the succesfully completed diploma examination.
The apparatus „vertical reduction furnace“ is an electrical heated, static reduction apparatus and is used in terms of performing reducibility testing of lumpy iron oxide containing feedstock and to determine the characteristics of different coke types. The aggregate is basically consisting of an electrical heated, vertical oven with 3 separate heating zones and an [...]
The fluidized bed reactor can be used to check the reducibility of different iron ore fines in fluidized state by measuring the change of sample weight during reduction. The effect of different process parameters on the reducibility such as temperature, gas composition and pressure can be observed. An installed sub-sampling system allows taking out [...]
The GERO® High temperature vertical tube furnace HTR-V100-250/17 is used to observe the dissolution properties of slag formers and steel scrap in liquid slag and metallic liquids, respectively. Further, the refining of liquid slag is possible. The maximum temperatures are 1650 °C. The heating is carried out through molybdenum disilicide (MoSi2) heating elements with [...]
The Gero Carbolite HTRV 100-250/18 is used to observe the dissolution properties of slag formers and steel scrap in liquid slag and metallic liquids, respectively. Further, the determination of liquid slag properties e.g. diffusion coefficients is possible. The maximum temperatures are 1720 °C. The heating is carried out through molybdenum disilicide (MoSi2) heating elements [...]
Increasing requirements on the properties of steel are challenging steel plant operators. Controlled cooling, as a part of most metallurgical processes, takes an important role in fulfilling these requirements. Optimal cooling strategies help to adjust mechanical properties and to minimize the formation or promotion of surface defects. But not only the steel quality is improved; [...]
