一、前言在枕木生产中,合理下锯是节约木材、提高成材出材率和产品质量,降低成本的重要措施之一。为了做到合理下锯,需要考虑的因素很多。如弯曲原木和径差较大的5米枕资合理截锯的问题,合理留钝稜的问题,注意剔除原木的天然缺点合理配置主副产品的问题以及充分利用原木断面形状的特点提高枕木出材率的问题等。而过去在枕木生产中工人接触最频繁,潛力较大,而又尚未被人们所重视的因素就是原木断面形状与枕木出材率的关系问题。 I. Introduction In the sleeper production, reasonable under-sawing is one of the important measures to save timber, improve the timbering rate and product quality and reduce costs. In order to be reasonable under the saw, you need to consider a lot of factors. Such as curved logs and larger diameter 5 meters pillow reasonable cut reasonable question, reasonable to stay blunt edge problems, pay attention to remove the natural defects of the rational allocation of primary and secondary products, the problem and take full advantage of the characteristics of the cross-sectional timber to improve the timber Rate of the problem. However, in the past, the most frequent and potential workers in sleeper production have not yet been valued are the relationship between the cross-sectional shape of the logs and the yield of sleepers.
