a promising alternative to traditional proton exchange membrane fuel cells due to their lower cost and ability to use non-noble metal catalysts. A key component in is the anode electrode, which requires a conductive and durable material that can withstand the harsh alkaline conditions present in the fuel cell. Nickel felt is a material that has shown promise as an anode substrate for due to its high conductivity and durability.
Alkaline Electrolyte Membrane Fuel Cells have been gaining increasing attention due to their superior performance compared to Proton Exchange Membrane Fuel Cells . have faster electrochemical kinetics, lower catalyst costs, and weaker corrosion, making them an attractive alternative to . One of the main advantages of is the use of an alkaline electrolyte, which allows for the benefit of non-precious-metal catalysts, making commercialization more feasible. While are technically similar, the key difference is the use of a solid instead of an acidic in . Overall, offer significant advantages over and are a promising technology for fuel cells.

The infrared converter slag detection system uses a far-infrared thermal imager to monitor the situation of converter tapping in real time, and is connected to the main control computer in the electrical room through the conversion and transmission of video signals. The radiation intensity in the infrared wavelength range of 7-14um is different to distinguish molten steel and slag. In the later stage of the converter tapping, the molten steel gradually decreases, and the steelmaking slag is involved in the molten steel and flows out of the tapping hole. After the thermal imager recognizes the steelmaking slag in the imaging temperature measurement, it will give an alarm according to the slag content ratio threshold set by the software. The thermal imager will start the slide plate to close the tapping hole, so as to realize the control of the slag in the converter tapping, and ensure the maximum yield of molten steel and the minimum control of the steelmaking slag content.
The effect of slag detection in converter tapping is of great significance to the control effect of the slag amount. The converter slag detection and control system developed by our company conducts non-contact monitoring of the tapping steel flow through the far-infrared detector thermal imager. It can detect the slag condition in real time and output an alarm signal and control system, which can replace manual visual inspection and provide accurate, efficient and stable slag detection effect. When the system finds the slag, the intelligent control unit quickly makes a judgment of lifting the furnace and blocking the slag and outputs an alarm signal.
As shown in Figure 1, the system includes thermal imager, front purge protection box, front electrical box, power distribution cabinet, main control monitor, monitor of rocking furnace chamber, sound and light alarm, infrared converter slag monitoring software system, etc.

Graphite digestion instrument is one of the direct, effective and economical sample pretreatment methods for elemental analysis. The application of new heating technology has the advantages of rapid heating, program control, complete digestion, and temperature equilibrium.Â
Our devices are usually used in sample preparation for atomic absorption, atomic fluorescence, ICP, ICP-MS, polarography, etc.
7 advantages make sample preparation no longer difficult:
1. The fully enclosed design prevents heat loss to a large extent and effectively avoids the intrusion of acid mist;
2. High-quality graphite three-dimensional wrapped heating, samples are heated evenly;
3. Unique spraying process, the coating is uniform, firm, and will not fall off after long-term use;
4. Fast digestion and acid removal, high efficiency, and batch processing of samples;
5. PID digital temperature control system, excellent performance;
6. Easy operation, environmental protection and energy saving, cost saving
7. Split type: The controller can be placed outside the fume hood to reduce acid gas corrosion and have a longer service life.
Acicular roll, alloyed with the nickel, manganese and chromium with a bainitic-acicular-martensitic matrix has a higher UTS, hardness and wear resistance is more than the SGP quality. Semi-continuous carbides maintain the wear resistance, while at the same time exhibiting high strength and resistance to fire-cracks. The extensive heat treatment procedure ensures an acicular matrix. Acicular roll can be produced by static casting (Monoblock) or by using the centrifugal cast (CC) Double-pour method.
