Are you looking for innovative, efficient solutions for your steel production or foundry process? Microstructural Analysis, Hardness Testing, Heat Treatment, Elemental Analysis, Size Reduction and Particle Size and Shape Analysis, – the brands of Verder Scientific offer high-quality solutions combined with expert advice and support service worldwide.
CARBOLITE GERO offers solutions for heat treating (annealing and hardening) special metal alloys and stainless steel.
In recent years, we have created a range of products for the wire and strip industry including furnaces for annealing stainless steel tubes and custom furnaces for hardening and tempering strip steel used in the manufacture of razor blades. In addition, we have manufactured continuous furnaces for steel wire with up to 22 simultaneous lanes and temperatures ranging from 200°C to 1100°C. These custom furnaces can be designed for single/multi-zone operation with inert or reactive atmospheres and optional water quenching and compliance with AMS 2750E.
Carbolite Gero's GLO sealed vacuum retort furnace is available in 4 sizes (40, 75, 120 & 260 litres). With a maximum temperature of 1100°C and fast cooling options, this is a perfect solution for annealing, hardening and tempering. An optional debinding package adds the ability to use this same furnace for debinding or pyrolysis.
ELTRA develops combustion analyzers for precise and sensitive CHNOS determination in solids.
Steel plants observe the decreasing carbon content during the whole steel production process from raw iron with up to 4-5% carbon to a few ppm in stainless steel. The carbon content influences not only the texture, but also the material properties of iron, such as magnetism, hardness or elasticity. Because of this, it is important to determine the content of carbon and sulfur quickly and efficiently during all production stages.
Modern combustion analyzers, like ELTRA’s ELEMENTRAC CS-i, require only a nominal analysis time of 40 seconds to determine both carbon and sulfur content. The determination in this way is fast, easy, and can be carried out by academic and non-academic staff alike.
QATM manufactures machines for materialography (metallography) and hardness testing used in quality control processes.
Steel parts require thorough testing, for instance, after the heat treatment process. QATM’s wide range of high-quality machines for cutting, mounting, and grinding/polishing allows for a perfect surface preparation as prerequisite for reliable microstructural analysis.
Thanks to automated solutions, such as the innovative Cut-off Machine Brillant 240, sample preparation is convenient and reproducible. The new, modular Hot Mounting Press Opal X-Press is ideally suited to obtain samples with low shrinkage and high edge retention.
QATM also specializes in the development and manufacture of innovative hardness testing machines.
Hardness is one of the most important material characteristics for steel producing and heat treatment companies. QATM instruments combine the two essential requirements for hardness testers integrated in the production process: robust design and simple operation. For hardness analysis, the Q150 hardness tester series is available as compact semi-automatic Rockwell tester or as fully-automatic universal hardness tester.
QATM is also able to provide customer-specific hardness testing plant solutions, e. g. in-line hardness testing portals or hardness testing machines with integrated milling units for surface preparation called “Qsolution”.
RETSCH provides size reduction and sieving equipment designed for sample preparation and characterization of solids.
A variety of raw materials and slags need to be analyzed with regards to their mineralogical and chemical composition to optimize the steel production steps where these materials are involved.
At each stage of the production, samples must be taken, processed and analyzed to ensure quality control without gaps. RETSCH offers a range of instruments suitable for sample preparation.
Microtrac MRB is the leading manufacturer of image analyzers for measuring particle size and particle shape of bulk materials.
Particle analysis is an essential part of the quality control process of different materials that are used in the steel and foundry industry:
