Drying equipment needs a comprehensive and multi-level energy-saving transformation
By alloying several percent of carbon with a minimum, 12 % alloy (primarily chromium), hard carbides are formed and dispersed throughout the surfacing deposit.
These dispersed carbides are much harder than the surrounding matrix and provide excellent abrasion resistance. They are used when the primary wear factor is abrasion. At the lower end of the carbon range (less than 3 %) the quantity of carbides is small compared to the matrix where they are dispersed.
These alloys exhibit good abrasive wear resistance while retaining good toughness. These carbide-surfacing alloys are used to resist a combination of abrasion and impact. As the carbon content increases (to as much as 7 %), in the carbide containing alloys, the abrasion resistance increases and the toughness decreases. This is due to the higher percentage of carbides. As carbides are undermined and knocked out by moving abrasive particles, additional carbides are uncovered to further resist abrasives and delay wear as shown in the diagram to the right.
The low carbon steel base plate enables the plate to be welded, bolted or studded to existing structures, while the hard facing provides the premier wear-resistant surface capable of working in all applicable service conditions at either ambient or elevated temperatures.
HP Wear Resistant Group offers various products of wear plates namely Cr-Carbide Weld Clad Plates, Smooth Surface CCO plate, Heat Treated Wear Plates (AR Plate or Q&T Steel), Casting Plates, Tungsten Carbide Coated Plates in various grade and multiple size options.
Due to its excellent properties, HP Wear Plates work for long-lasting service life and super performance, which are well applied to the industries like Cement Plant, Steel Mill, Mining Site, Power Generation, Construction where need combat with abrasion.

With the emphasis on environmental protection by human beings, improving the environmental protection measures of drying equipment to reduce the leakage of dust and exhaust gas will also require further research. Experts said that through technological competition, a strong, united, superior-sufficiency, and nurturing a leader in the industry, may be just around the corner.
Experts said that in exploring the new development path for drying technology, comprehensive consideration must be given to energy efficiency, environmental protection, and product quality in order to achieve comprehensive, coordinated, and sustainable development. To implement the development strategy of high efficiency and green drying, we must first take the path of resource-saving development, and change the single extensive drying into combination and intelligent drying.
Experts said that China's drying plant should not only undergo fundamental transformation from the drying process, but also carry out comprehensive and multi-level energy-saving technological transformation and vigorously develop drying technologies that apply renewable energy and industrial waste heat. In order to develop from a large dry country to a powerful one, China must further strengthen basic theoretical research and lay a solid foundation for applied research and application development. Technically, it is necessary to strengthen the degree of automation, test technology, manufacturing process, material design, etc. .
In addition, the government should establish and improve comprehensive evaluation criteria and industry standards for drying equipment, establish macro-control and market regulation mechanisms, and accelerate the upgrading of drying technologies. The market demand promotes product innovation, and the drying equipment industry is committed to the research and development of new products. The future development prospects are immeasurable.
