在一般冷铸平面轧辊上,白口深度只能控制在12～40mm的范围內。当轧槽深度小于40mm时,問题比較容易解决,即先铸成带有12～40mm白口深度的平面軋輥,然后在平面上車切軋槽;如軋槽很深,超过40mm吋,若仍用平面轧輥車切軋槽,則軋槽势必要深入到麻口层(如图1)。这种軋槽,由于磨損不均匀,即白口层 In the general cold-casting plane roll, white mouth depth can only be controlled within the range of 12 ~ 40mm. When the groove depth is less than 40mm, the problem is relatively easy to solve, that is, first cast with 12 ~ 40mm white mouth depth of the plane roll, and then cut in the plane car slot; such as groove deep, more than 40mm inch, if still Roll with a flat roll rolling groove, the rolling groove is bound to go deep into the mouth layer (Figure 1). This groove, due to uneven wear, that white layer
