为了提出目前适合于我国的犂铧钢材,解决一般小型农具厂生产可锻铸铁犂铧时存在不耐磨的问题,以及使犂铧在磨损过程中能有良好的自磨锐作用,以获得较稳定的耕作质量起见,我们在对犂铧的磨损机理及自磨锐作用进行了粗浅分析的基础上,对于几种国产钢材和两种基体的可锻铸铁的耐磨性,以及单面渗碳钢材的自磨锐作用进行了一些 In order to put forward the plowshare steel that is suitable for our country at present, solve the problem of non-wearable when there are ductile iron plowshares in the general small-scale farm machinery factory, and make the plowshare have a good self-sharpening effect in the process of abrasion, so as to obtain more stable Tillage quality for the sake of our plowshare wear mechanism and self-sharpening role based on the shallow analysis, for several domestic steel and two kinds of malleable iron substrate wear resistance, as well as single-sided carburizing steel self-grinding Sharp role a bit
