Optical spectroscopy is a technique for measuring light intensity in the ultraviolet, visible, near - infrared and infrared wavelength ranges which consists of entrance slit, collimator, grating, focusing optics and detector. The application of spectroscopic measurements at the Chair of Ferrous Metallurgy is to monitor the emission of plasma arc from the hydrogen plasma [...]
There are several heat treatment furnaces available in the lab. They differ in capacity, heating rates and maximum temperatures. A special equipment is the high temperature chamber furnace, which can reach a maximum temperature of 1600°C. The lining consists of vacuum pressed Al2O3plates. Technical Specifications: max. temperatures: 1100°C, 1300°C, 1600°C furnace chamber volumes: 13l [...]
The “Spectromaxx” optical emission spectrometer is used for the analysis of Fe-, Al- and Cu-based alloys, covering 20 methods, 45 elements and different adapters for various sample geometries. The spectrometer determines all important elements used in the metal industry, including carbon, nitrogen, phosphorous and sulfur, allowing precise analysis with ease of use and maintenance. [...]
The Vacuum-Induction-Furnace is used for when high gas purity is requested. The chamber is vacuumed and further flooded with inert gas e.g. Argon 5.0. 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 [...]
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 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 [...]
