At present, ceramic particle reinforced steel-based wear-resistant composite materials are mostly prepared as surface-hardened surface composite materials.Recently, the “Research and Application of Low Alloy Steel/ZrO2-Al2O3 Honeycomb Ceramic Composite Material” jointly researched by Zhengzhou Dingsheng Engineering Technology Co., Ltd. and Zhengzhou University won the 2012Second Prize of Henan Province Industry and Information Technology Achievement Award, Honeycomb ceramic composite materials have once again attracted a high degree of attention in the wear-resistant material industry.
It is understood that the Achievement Appraisal Office of the Science and Technology Department of Henan Province appraised the scientific and technological achievement, “The project has advanced technology and reasonable process. It has innovations in the low-alloy steel/ZrO2Al2O3 honeycomb ceramic composite process and its application in low-impact load liners. Leading domestic level.” The appraisal opinion, which will play a huge role in promoting the development of my country’s wear-resistant materials industry.
Big golden toothAlloy wear-resistant hammer
Especially after my country’s wear-resistant composite materials have gone through several stages such as two-component bimetallic materials, high-chromium iron steel inlay casting materials, and high-chromium iron steel mechanical composite materials, in recent years, the high manganese steel inlay casting marked by composite sledgehammers Cemented carbide (or wear-resistant cast iron) composite materials have realized industrial production and application.
The third-generation large gold tooth inlay and cast hard made by Zhengzhou DingshengAlloy HammerAs an example, in the course of work,Crusher hammerAs the main wear-resistant part of the crusher, it is in direct contact with the material. In order to improve its wear resistance, traditional hammers are mostly coated with a layer of tungsten-titanium alloy with cemented carbide on the working surface, and the wear resistance is not high. The third-generation “Big Golden Tooth” crusher hammer is the latest result jointly developed by Zhengzhou Dingsheng and Xi’an Jiaotong University Wear-resistant Materials Joint Research Institute. The diamond tungsten-titanium alloy can resist severe abrasive wear, and its life span is 30%-100% longer than the original ordinary high-manganese steel hammer.
With its good wear resistance, the composite sledge hammer has set a 17-month service life record of 3.2 million tons of crushed materials during the use of Jiangxi East Cement Co., Ltd. It is deeply loved by cement factory customers and has won “China’s Best Hammerhead Award”, “Best Cost-effective Product Award”, and “Science and Technology Progress Award” three honors.
