轧机轧辊是冶金企业每年消耗最多的零件之一。我厂每年为各钢厂提供几千吨钢轧辊,其中带扁头轧辊一千多吨。在加工这类轧辊过程中,粗铣一个轧辊扁头一般需要40多个台时,造成成本高。近几年来,采用氧-丙烷切割,最大切割厚度可达两米以上,精切表面的光洁度在▽3以上。我厂对氧-丙烷火焰切割轧辊扁头进行了初步试验,切割一个φ520mm轧辊扁头试块,仅用11分钟,切割后的表面平整,可以代替铣床粗加工轧辊扁头。
Rolling mill is one of the most consumed parts of the metallurgical industry each year. I plant each year to provide thousands of tons of steel mill steel mill, with more than 1,000 tons of flat-head roll. In the process of processing such rolls, roughing a roll flat head generally takes more than 40 units, resulting in high costs. In recent years, the use of oxygen - propane cutting, the maximum cutting thickness of up to two meters above the fine finish surface finish ▽ 3 or more. I plant oxygen - propane flame cutting roll flat head for a preliminary test, cutting a φ520mm roll flat head test block, only 11 minutes, cutting the surface smooth, you can replace the mill roughing roll flat head.
