目前,国内各厂轧制等边角钢的很多,就孔型设计来说,当蝶式孔型系统因其具有无比的优越性而代替了直腿孔型系统之后,各厂已相继予以采用。因此各厂之间在系统上便存在了这一共同点,但是由于设备各有不同及经验各异,经过改进过程达到稳定的孔型特点也各有不同。我厂中型车间在轧制6.5和7.5号角钢过程中也曾积累了若干经验。虽然经验还不多,但最后终能使生产稳定。这说明这些经验还有一部分是有些参考价值的。一、关于稳定性问题一种产品的质量、产量、作业率的高低取决于很
At present, the domestic mill rolling a large number of other side angles, the hole design, when the butterfly hole system because of its incomparable superiority and replaced the straight leg hole system, the plant has been adopted. Therefore, there is a common ground among the plants in the system. However, due to the differences in equipment and experiences, the hole characteristics that have been stabilized through the improvement process are also different. I workshop medium-sized workshop in the rolling 6.5 and 7.5 angle during the process has also accumulated a number of experience. Although not much experience, but ultimately make the production stable. This shows that some of these experiences are some reference value. First, on the issue of stability The quality of a product, output, operating rate depends on the level of
