Anewprocesstoincreasetoughnesswasproposed, andexcellentresulthaeenobtainedinthepracticeKeywords: hi Qu chromiumwhiteiron; toughness; newprocess0 introduction of high chromium white cast iron is today one of the best anti-wear materials, in the mining, power generation, building materials are widely used in industry and non-alloy and low Taijin White than cast iron, it sets a higher hardness, MC, carbides,<a href="http://www.uggsstivali.org" target="_blank">ugg stivali</a>, and the distribution was lath isolated,<a href="http://www.monclerjackens.net" target="_blank">Moncler jacken</a>, surrounded by the plastic substrate, so brittle relatively small. And after annealing can be thread cutting and vehicles, which created the conditions for its application. But it is still cast iron, ductile than other metal materials, or too low, the production process is easy to produce cracks and scrapped. This paper argues that the production of high-ming, cast iron should pay attention to the problem, 9 ~ - ~ r Shaoti high toughness of the new technology, new technologies, for reference. 1, the microstructure of high chromium cast iron microstructure of high chromium cast iron generally contain no more than 40% of the high hardness of the MC carbide, to ensure its abrasion resistance, the volume occupied by either the matrix is less than 60%. If the increase in carbon content, the carbonation Received Date: 30 August 2000 Author: Su Ying Lung, male, 1937, 1960, graduated from the Department of Mechanical Engineering, Dalian Polytechnic school, the current National Institute of Beijing University of more materials, research direction: high toughness ductile iron, iron and anti-mushroom comfort grub ductile iron and other things he volume of content increases, improved abrasion resistance, and increased brittleness. Especially the carbon equivalent over 4.3%, the microstructure appears primary carbide, toughness and other mechanical properties are to be significantly reduced. Eutectic cast iron with carbon content of chromium and silicon content varies, and is calculated as follows: C # = 4.3% a 0.31Si 0.05Cr a high abrasion resistance of chromium cast iron matrix in Table 1, Table lCrl5Mo3 the wrong type of cast iron with high abrasion resistance of the matrix on the impact of ...

Sulfur in liquid iron by adding iron, melting with S can increase its capacity to improve their breeding performance.
