一、负偏差轧制的意义在轧钢车间推行负偏差轧制将给我国的社会主义建设事业带来巨大的好处。因为:第一,当轧制品还要继续加工时,公差的大小将直接地影响到钢料的损失数量,例如表面需要加工的元捧对所使用的轧制原料直径的选样时,必须考虑到要车削掉的一层而得到表面没有黑皮的制品。这时车削掉的钢的数量将随着原料公差尺寸的加大而提高,同时车床也将浪费掉许多为了车削多余的钢的时间。表面不再加工而直接使用的建筑钢材,使用部门的设计是按照最小的负偏差进行的,多余的钢也是浪费掉。按照目前部颁际准规定的允许上限公差和下限公差轧制产品的每公尺重量的差别是相当大的,例如直 The Significance of Negative Deviation Rolling The implementation of negative deviation rolling in the rolling shop will bring huge benefits to our country’s socialist construction. Because: First, when the rolled products to be continued processing, the size of the tolerance will directly affect the amount of loss of steel, for example, the surface of the metal processing needs of the selection of rolling material diameter must be selected Taking into account the layer to be cut off and get the surface without black skin products. At this moment, the amount of steel to be cut will increase with the increase of the tolerances of raw materials, and the lathe will also waste a lot of time for turning excess steel. The surface is no longer processed and used directly in the construction of steel, the use of the design department is based on the smallest negative deviation, the excess steel is also wasted. The difference between the allowable upper tolerances and the lower tolerance tolerances per metric foot of a rolled product according to the current ministerial standards is considerable, such as straight
