前言在金属制品钢丝拉拔行业,随着现代化工业的发展,设备不断革新,大都采用连续高速拉丝设备,拉拔负荷、拉丝速度、钢丝产量都不断提高,所使用的模具——硬质合金拉丝模,虽然使用以来是可靠的,但也表现出不相适应的一面。磨损加快、模耗大增、拉拔中模子更换次数也频频增加,不仅增加了成本,而且作业率下降,使生产受到影响;更重要的是它限制了拉丝速度的再提高。对于拉丝行业赶超世界先进水平、实现现代化、起到阻碍作用。
Preface In the metal wire drawing industry, with the development of modern industry, equipment innovation, most of the continuous high-speed drawing equipment, drawing load, drawing speed, wire production are continuously improved, the use of the mold - Carbide drawing Molds, although reliable since use, have also shown incompatible aspects. Faster wear and tear, mold consumption increased, the number of dies in the drawing also increased frequently, not only increased costs, and operating rate decreased, so that production is affected; more importantly, it limits the drawing speed and then increase. Drawing industry to catch up with the world advanced level, to achieve modernization, play an obstruction.
