犁铧是量大面广的易损农机基础件,每年约消耗约万吨左右钢材。但是目前国产的65SiMnRe钢犁铧使用寿命很短,在东北黑粘土中可耕300～500亩,在北京沙壤土中可耕100～200亩,在海南岛沙土中只耕50～80亩。犁铧磨损变钝后严重降低了耕作质量,并使油耗增加。为了提高犁铧的耐磨性,延长使用寿命,我们决定对犁铧进行等离子堆焊的研制工作。研制结果表明:一片等离子堆焊犁铧能顶三片标准犁铧用,可提高
Plowshare is a large amount of vulnerable agricultural basic parts, about every year about consumption of about 10,000 tons of steel. However, the current domestic 65SiMnRe steel ploughshare has a short service life of arable land of 300-500 mu in black clay in the northeast of China, 100-200 mu of arable land in Beijing’s sandy loam, and 50-80 mu of land in Hainan Island. Plowshare wear and tear dull severely reduced the quality of farming, and to increase fuel consumption. In order to improve the ploughshare of the wear resistance and prolong the service life, we decided to Plowshare for plasma surfacing research and development work. Development results show that: a plasma plow plow can top three standard plowshares can be used to improve
