Corrugated Roller Working Condition Currently Used in Carton Factory Normal > For any type of corrugating roller, it has the same basic function and wear mechanism. Corrugated paper at a high speed, continuous bending section into the ironing process, the line pressure constantly to the relative displacement flute corrugated roll nip to squeeze the top and create friction, and by the inclusion of the minerals contained in the base paper durum RCC The impact of the corrugated roll makes the top of the corrugated roll subject to severe wear, gradually grinding into an irregular shape from the arc, continuous high-speed operation, and the height of the rake tooth gradually becomes lower, so that the produced cardboard gradually tends to the standard lower limit. Some corrugating rollers with low surface hardness will also cause dimples and depressions in the dome's surface, exacerbating the wear process. Normal > Because the production line is often not full of paper, the uneven wear of the corrugating roller surface causes the corrugating roller to be concave and cause the cardboard to be debonded and foamed. The low-hardness corrugating roller will continue to fall down, tilt, twist, increase ellipticity and runout error due to plastic deformation under the continuous high-speed single-tooth meshing and directional operation, and accelerate the service life and economic performance of the corrugating roller. Normal > Normal > The working principle and wear mechanism of the above corrugating roller can be seen that the process of corrugating roller is a process of continuous wear. The forms of damage are summarized as: Normal > Normal > Ø         Normal wear, wear parts are domes; Normal > Ø         The pits and depressions caused by the soft roll surface, the thinned reinforcement layer and the poor paper quality; Normal > Ø         Poor management caused by the concave; Normal > Ø         The base body is soft, and the roll is poor in the quality of its manufacture. Normal > Normal > How to extend the life of corrugating rollers Normal > Normal > For any grade of corrugated cardboard production line, corrugated rollers are always one of the most expensive consumable parts. Its economic performance and service life have always been an important issue for the corrugated box industry. Raising the wear resistance of the corrugating roller and prolonging the service life of the corrugating roller is an effective method to reduce the production cost of the corrugated board. At present, there are light industrial standards in China, and there are also corrugated roller manufacturers' enterprise standards that effectively control the quality of corrugating rollers. Normal > Normal > The surface hardness of the tooth profile and the depth of the hardened layer are shown in the following table. The thickness of the coating that is completed under different heat treatment processes determines the hardness of the corrugated fiber and is an effective parameter of the corrugating roller. Normal > Normal align=center> Light Industry Standard QB/T1447.1-2000 Single Side Corrugated Board Machine  Corrugated Roller Normal > heat treatment 1.
