Polytechnology: recent advances cost-effective wear-resistant materials
  [Note] core "On the consumption ratio of wear-resistant materials, mining accounted for more than 50%, cement accounted for 30% -40%, and 10% are thermal power. Wear cement industry has maintained a close relationship," Chinese cement senior adviser said in net, the China Agricultural Machinery Institute Process Engineering professor Polytechnology recently accepted China Cement Net reporters.
  With the development of industry, wear industry is also put forward new demands, mining, cement, thermal power is consumed mainly wear-resistant materials industry. With the development of the cement industry, the demand for greatly increased wear-resistant products, cement equipment and production technology updates to the wear-resistant materials and technology have put forward higher requirements. "On the consumption ratio of wear-resistant materials, mining accounted for more than 50%, cement accounted for 30% -40%, and 10% are thermal power. Wear cement industry has maintained a close relationship," senior adviser China Cement Net, China Agricultural Machinery Institute as a professor of Engineering Technology Polytechnology said in an interview with reporters recently China Cement Net.
  2012 Fifth Summit on the international grinding Polytechnology share the importance of highly wear resistant materials in cement process technology in the building materials, and in the Seventh International Summit on May 22 grinding, the reporter learned Polytechnology The detailed interpretation of "cost-effective wear-resistant materials" to help companies optimize cement grinding process to achieve lower production costs and improve the performance of cement.
  So, what is the cost-effective wear-resistant materials? Professor Zhou Pingan think when conditions have the following aspects:
  1, in the wear-casting, and computer simulation. Wear casting is reflected in the structural design Polytechnology said that the current scale enterprises have relatively basic computer simulations have been achieved, such applications are mostly imported, you can simulate the product in operation.
  2, wear-resistant materials variety of changes. From the development history, the traditional building materials commonly used in industrial wear-resistant materials are: Nickel hard cast iron, low chromium cast iron, high chromium cast iron, high manganese steel and alloy steel. In the cement industry, it is mainly made of high chromium cast iron. Polytechnology said chromium limited resources worldwide, especially in China is a poor country chromium, in the past decade, the consumption of chrome resources are large, resulting in high-carbon ferrochrome 4-5 times the price doubled, and more importantly, chrome consume a lot of resources would lead to chromium depletion of resources, which is the development wear industry has brought a lot of limitations. In addition, chromium flow causes soil contamination, therefore, try to use the alloy material is currently advocated. "We have developed a strong toughness carbide-containing Austempered Ductile Iron (CADI). This is a wear-resistant materials industry in a new system, and is used, and achieved good results," said Zhou Pingan.
  3, change the sales model. The use of industry cooperation and e-commerce to replace the traditional sales model. Polytechnology said that the main drawbacks of the existing transaction is a traditional trading patterns; prices transparent; the money can not be timely payment; unequal bargaining position; quality can not be guaranteed; buyers and sellers and other shady transactions. The use of industry cooperation and e-commerce instead of the traditional sales model, can reduce intermediate channels and improve efficiency. "In recent years I have been very concerned about the development of China's cement spare parts network, the Chinese cement spare parts network marketing model can serve as a model for future marketing model of the entire industry!"
  4, mechanized production. Cost is a concept, often at a low price in the past tender based, but in fact there is a comprehensive evaluation of the problem, buy a cheap but very likely the resulting benefits are not good.
  For the future development of wear-resistant materials industry Polytechnology said it would try to adopt new technologies, focusing on their overall effectiveness. In addition, industry consolidation will become the next focus for a long period of time. For a long time, wear-resistant materials industry are based on small and medium enterprises as the main body, there is a relatively small size, small product range, operating disturbances, disorderly competition and other issues. A distinctive mark of the future development of wear-resistant materials industry is the business of the group, the business group's major trend, driven by large-scale restructuring of production will be product diversification, standardization and further meet the major sectors of wear material needs direction.
