Advantages of tungsten carbide corrugated roll (compared with traditional roller) :
1. Improve the quality of paperboard:
A. The tooth type design of ordinary corrugated roller is difficult to design in some parameters (such as top circle and tooth) because of wear. And the tungsten carbide corrugated roll is optimized in tooth shape design because it is not worn.
B, ordinary corrugated roller high tooth top round and change is big, the cardboard quality is not stable, the core of paper and glue roller gap with corrugated roller wear and expand, at the same time, the increase of wear top round after all lead to excessive amount of glue, soft and easy to bend the board wings; The tungsten carbide corrugated roll is durable, the tooth is high, the top circle is almost constant and the quality of paperboard is stable.
2. Cost saving:
Type a, use less paper core: stare blankly design corrugated rate is small, with core paper 2-8% less commonly, it is very important to the cartons enterprises, because ordinary corrugated roller wear fast, have to take into account the leng some high on original design, top circle bigger factor to guarantee a certain life; And the tungsten carbide corrugated roll because of the wear-resisting does not have this problem.
B, reduce the waste: among ordinary corrugated roller wear too much, into a concave, reproduction wide board is easy to produce waste paper, because both ends can be crushed or not paste (degumming blister), then you have to go to the ends of the grinding roller, wide board to go, to maintain the life of the roller; The tungsten carbide corrugated roller does not exist in the long service life.
C. Increased life: carbide rollers are generally two to four times longer than ordinary rollers.
D. Reduce the amount of glue paste: the original design tooth circle is small, there is no wear top circle to become large, there is no intermediate wear, which leads to uneven distribution between the two ends and the intermediate glue.
E. Reduce the damage to other units: such as glue roller, pressure roller, etc., because the concave of ordinary corrugated roller is destructive to the adjustment and use of other parts.
F. The replacement frequency of corrugated roller is reduced. It is important that the tungsten carbide corrugated roll is almost constant in the whole operating life. The wear of corrugated top is the main reason of poor quality of paperboard and replacement of corrugated roller.
