1.负偏差生产概况从60年代中期起,我厂以生产角钢为主产品的一套中型轧机即按负偏差轧制组织生产,定尺钢材以理论重量交货。从1976年开始,公司将该车间负偏差轧制的效果纳入考核指标。现将历年来负偏差轧制情况列于表1。1976～1986年间,该车间的负偏差量,即不消耗任何原料而得到的产品为77398t。

1. Negative deviation of production profile Since the mid-60s, I plant to produce a set of medium-angle angle rolling mill products that are produced by the organization of negative deviation rolling, fixed-length steel to the theoretical weight of delivery. Since 1976, the company has included the effect of the negative deviation rolling of the workshop into the evaluation index. Now the negative years of rolling over the years are listed in Table 1. 1976 to 1986, the negative deviation of the workshop, that is, without any raw materials to get the product is 77,398 tons.
