Method for improving steel passing amount of tungsten carbide roll collar and high-speed wire rod production method

The invention discloses a method for improving the steel passing amount of a tungsten carbide roll collar and a high-speed wire rod production method, and relates to the technical field of high-speed wire rod rolling. According to the method, supplied steel billets are subjected to finish rolling, first diameter reducing and second diameter reducing in sequence; the inlet temperature of the first reducing diameter is 810-850 DEG C, and the inlet temperature of the second reducing diameter is 10 DEG C lower than the inlet temperature of the first reducing diameter; the hardness of the first reducing roll collar is 2 HRA lower than that of the finishing roll collar, and the hardness of the second reducing roll collar is 2 HRA lower than that of the first reducing roll collar; according to the specification, the model and the producing area of the twisted steel, a corresponding hole pattern lettering mark is arranged on a finished thread roll collar, the hole pattern lettering mark comprises a plurality of lette
