🗜️ Can OES Provide Inclusion Analysis during Steel Production?
Non-metallic inclusions are of considerable importance for the steel industry due to the dramatic influence that even small amounts of them may have on properties, mechanical and otherwise, of the metal or on the production process itself. Inclusions can have positive effects and may increase the value of the steel, but most often inclusions signify quality problems and reduced value.
The modern reference for inclusion analysis is the SEM/EDX (scanning electron microscope coupled with energy dispersive X-ray fluorescence spectroscopy). This analytical process takes typically several hours, including sample preparation and interpretation, which is far too long to be applicable to production control.
Within recent years we’ve seen the development of extremely fast and economical OES (optical emission spectrometry) methods which are able to provide inclusion information even during the steel production process. The method uses the principle of Single Spark Acquisition (SSA), where signals from the individual “single sparks” are not summed as in conventional OES acquisition, but processed with special algorithms.
Innovating Metallurgical Equipment Design to Meet Flotation Plant Layout Challenges
One of the key design principles that holds true is that minimizing the equipment’s hydraulic head requirements can potentially minimize the number of pumps needed in a plant. This not only reduces energy demand, but also lowers operational and maintenance costs. Additionally, by minimizing the head requirement, one can free up space for additional process functions needed in the plant.
An example of this principle in action is the design of large flow rate sampling equipment. Traditional sampling systems for flow rates of 35,000 cubic meters or more often require splitting the final tails into two samples, which results in complex reconciliation and recombination processes. However, samplers that can operate at flow rates of up to 40,000 cubic meters an hour and incorporate all sampling stages at one floor level not only simplifies the process, but also saves height in the tails of the plant, reducing the overall cost of construction.
Why are XRF Analyzers Used in Scrap Metal Recycling?
XRF (X-Ray Fluorescence) analyzers are commonly used in scrap metal recycling because they provide a fast and accurate way to identify and sort different types of metals. Sorting is necessary to provide customers with the correct materials as the quality of the next product could be compromised if the metal is mis-identified.
XRF analyzers work by emitting X-rays onto the metal sample, causing the atoms in the metal to emit characteristic X-rays that are detected and analyzed by the device. This allows for the identification and quantification of different elements in the sample, including the type and quantity of metals present.
Deconvoluting Aluminum Alloy Corrosion with Multimodal Correlative Microscopy
Aerospace manufacturers are continuously exploring novel materials that could support the next generation of aircraft design. This includes advanced aluminum alloys that incorporate increased zinc content, which results in a tougher material with higher quench sensitivity. Unfortunately, these improvements often come at the cost of decreased cracking resistance. Understanding the precise source of environmentally assisted stress corrosion cracking (EAC) would allow manufacturers to finely tune alloy production and potentially overcome the shortcomings of these novel materials.
Using machine learning techniques in wine quality testing
The Profiling capability from Thermo Scientific™ SampleManager™ LIMS software provides an innovative way for laboratories to predict test results using historical data and novel machine learning (ML)-based techniques. For example, a food and beverage company might apply the Profiling capability to enable supervised learning in the food production process. In this case, SampleManager LIMS would use historical data to gain an understanding of the critical variables that determine whether a product is safe for consumers. This holistic approach considers not only the values of the individual critical variables themselves, but also the relationships between them. If a sample were to be flagged as failing, the system would alert stakeholders in advance to issue adjustments or investigations to avoid any risk to finished products.
In a wine production facility, the result of the “Quality Test” is of utmost importance. The laboratory has great flexibility and control over the testing process, so they could use the Profiling capability to redefine the order of the standard tests conducted to a wine sample.
An App for Bulk Material Handling and Analysis in Cement Manufacturing
Cement analyzers provide real-time online elemental analysis of an entire raw material process stream using technologies like Prompt Gamma Neutron Activation Analysis (PGNAA) and Pulsed Fast Thermal Neutron Activation (PFTNA) technology. These analyzers can aid in consistent stockpile quality, reduced chemistry variability, decreased kiln upsets and kiln fuel costs, extended quarry life, and minimized use of highest cost materials.
Mining 4.0 with SampleManager LIMS
The mining industry presents unique and complex challenges when it comes to data management. Responding to international regulations, integrating technologies used in different business units, controlling accurate inventory data and reliably managing mineral information are critical needs.
Companies in the mining industry need to efficiently manage all the variables that come into play, especially considering that it is a long production chain made up of diverse units that are physically separated from each other. Integrating the laboratory data with the rest of the production chain is key to improving operations and unlocking growth.
SEM-EDS Failure Analysis in Tire Manufacturing
Tires are often considered as low-tech commodities. However, contrary to popular perception, tires are actually highly engineered structural composites. Tires contain many rubber compounds (up to 20, with several types of microstructures) that provide different levels of grip and traction. Fillers are added to the main polymer matrix to facilitate rubber reinforcement.
Tire failures often occur due to a lower or decreased material quality, and an optimal and homogenous dispersion of all the different fillers is a key factor for a higher material quality. Analytical techniques like SEM-EDS are required to understand the root cause of a failure but the material contrast obtained from a backscattered electron image is not enough to distinguish between the large variety of materials employed.
This application note demonstrates that the live quantitative elemental analysis of Axia ChemiSEM provides an efficient and easy way to characterize the different fillers, despite their similar compositional contrast.
