Oxidation processes are almost unavoidable in the production and further processing of steel. Therefore, a better understanding of its mechanisms is crucial. Simulating selected process steps, like casting, heat treatment or hot rolling, by simultaneous-thermal-analysis (STA-DTA/TG measurements) improve the understanding of the influence of process parameters and steel composition on the formation of surface [...]
The LECO ON736 is used for the analysis of oxygen and nitrogen in solid steel samples. Detection method: Oxygen: Infrared Absorption Nitrogen: Thermal Conductivity Sample weight: ~ 1g Measuring ranges: N: 0,5ppm – 3,5% O: 0,5ppm – 0,2% Contact: Details
High Temperature Laser Scanning Confocal Microscopy is used to observe surfaces of samples at elevated temperatures up to 1750°C. The set up consists of a He-Ne Laser as a light source and an infrared heating chamber. The He-Ne laser in combination with a pinhole blocks out thermal radiation of the sample enabling the observation [...]
The High-frequency remelting (HFR) and spin-casting machine allows the rapid production of laboratory alloys by induction melting under argon protective atmosphere. The turbulent flow from the induction provides an excellent mixing of the melt and the closed melting chamber prevents oxidation. The subsequent (optional) centrifugal spin-casting into a copper mould supports also the homogenization [...]
The tammann furnace is an electric resistance tube furnace from the manufacturer Ruhrstrat GmbH (Ruhrstrat HRTK 32 Sond.) with a maximum operating temperature of 1700°C. With the experimental set-up of the tammann-type furnace it’s possible to investigate a huge variety of steel systems. Since change in atmosphere and alloying in any order is feasible, [...]
The fluidized bed cold testing model is used to identify the flow regimes and to measure the entrainment of the materials at defined gas velocities. The dimensions of the apparatus are equal to the hot fluidized bed reactor at the chair of ferrous metallurgy. Therefore, materials can be tested concerning their fluidization behaviour using [...]
The GAM 200 is a mass spectrometer for fast and precise multi-component gas analysis.The variety of gas inlet systems and the flexibility of the InProcess-Quadstar software allows the user to adapt the system to the most diverse tasks in industry and laboratory. Product Highlights Specific and sensitive gas analysis Multicomponent analyzer Large dynamic measuring [...]
The production of iron using hydrogen as a reducing agent is an alternative to conventional iron- and steel-making processes, with an associated decrease in CO2emissions. Hydrogen plasma smelting reduction (HPSR) of iron ore is the process of using hydrogen thermal plasma to reduce iron oxides. A laboratory-scale hydrogen plasma facility, which is called ‘Plasmette’, [...]
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 [...]
