斯太尔摩辊道风机超频提速的应用

摘要

为解决夏季生产预应力钢线材抗拉强度低的问题，对斯太尔摩辊道风机的使用现状进行了分析。通过对风机的超频提速，降低了环境温度对线材抗拉强度指标的影响，增加了预应力钢的索氏体组织比例，抗拉强度提高47MPa，达到了用户的使用要求。但风机超频提速后，必须增加维护的频次，防止风机烧损。冬季生产时，线材的冷却速度过快，需要预防出现马氏体等有害组织。%To solve the problem of low tensile strength of pre-stressed steel wire produced in summer, the present operation status of Stelmor roll table fan is analyzed.With over-clocking speed up of the fan, the influence of environment temperature on the wire tensile strength index is reduced, the ratio of sorbite structure in pre -stressed steel raised, its tensile strength increased by 47 MPa, reached the demand of customers.But to prevent the fan burned, its maintenance must be strengthened.In winter, because of too fast cooling, the harmful structure such as martensite must be prevent for the wire.
