Features of inclined areas: what to take into account

Caliber wear, despite its unevenness, can be compensated for by certain limits. At the same time, it is very important to know the rate of wear of the roller rolls of each stan’s cage depending on the rolling steel and profile. Consider the gradual increase in the production of calibers of the rolls of the final group of stories and setting up the camp after a certain period of time when rolling round steel with a diameter of 18 mm from steel stamp. H.

Included areas characterize an increase in the thickness of the strip or the size of the caliber wear, and vertical areas – a decrease in the height of calibers and strips as a result of the settings of the final group. Knowing the rate of wear of calibers and their number on the barrel of the roll, for each rolling in the profile, they develop a graph of transitions to new calibers and rollers of rolls. The high temperature of the end of the rolling in conditions of continuous camps favorably affects the accuracy of the finished profile. The slight distance between the working cages, the straightness of the process and the high rolling speeds provide high stability of the temperature regime, which is confirmed by the data. The maximum fluctuation of the temperature of the rolling blanks during the shift is 80 ° and is usually caused by a change in the temperature regime of heating of the workpieces in the furnace due to violation of the technological regime of rolling. This is a consequence of or the abnormal operation of the camp as a result of which they are forced to change the heating mode of the workpieces or a gross violation of the heat regime of the furnace in either case, the violation of the temperature control regime is determined by the change in time. From what was said, it is clear that a change in the rolling temperature on a continuous fine -grade camp should be considered as a evenly increasing factor.
