前言近年来,蔗糖厂切蔗使用的切蔗刀,几乎全部采用铸造的颗粒状碳化钨硬质合金管状焊条(以下简称碳化钨焊条)堆焊。我厂已使用六年多了。实践证明,它比采用45号优质碳素钢和碳素工具钢制的切蔗刀具有制造工艺简单,节省工时、合理使用钢材、降低成本、提高生产率等优点。这种改革后的单道堆焊的拖刀型切蔗刀(图1),可以使用两个榨季。国外进口的切蔗刀只能使用一个榨季左右。
Foreword In recent years, the cane sugar cane cutter cut cane used, almost all of the use of casting granular tungsten carbide tube electrode (hereinafter referred to as tungsten carbide electrode) surfacing. I plant has been using more than six years. Practice has proved that it is better than the use of 45 high-quality carbon steel and carbon tool steel cutter made of sugar cane manufacturing process is simple, save working hours, the rational use of steel, reduce costs, increase productivity and so on. This reform after a single-pass surfacing drag blade cutter (Figure 1), you can use two crop season. Cuttings imported from foreign countries can only use a crop around.
