斜轧钢球生产中,采用单头轧制时,轧辊每分钟转数不变时,生产的钢球越小,轧机机时产量也就越低。若采用可调速的直流电机驱动轧机,在生产小钢球时,虽然可以通过提高轧辊转数来增加机时产量,但增加的幅度有限。因为轧辊转数过高,轧件咬入轧辊时很容易出现打滑现象。同时,较长的坯料转动太快时也易容甩弯,造成卡钢。 In the production of slant-rolled steel balls, when the single-head rolling is adopted, the revolutions per minute of the rollers are constant, the smaller the steel balls are produced and the lower the output of the rolling mill is. If the use of adjustable speed DC motor-driven mill, in the production of small steel ball, though you can increase the roller speed to increase machine production, but the increase is limited. Because the roll number is too high, rolling bite roll prone to slip phenomenon. At the same time, longer billet too easy to turn when turning too fast, resulting in card steel.
