Corrugated carton factory conditions currently used For any form of Corrugated, it has the same basic functions and use of wear mechanism. Corrugated paper in high-speed, continuous bending section into the ironing process, the line under pressure constantly and the relative displacement of the top corrugating roll flute and squeeze rolling friction generated by base paper and contain mineral inclusions in the rolling impact of durum , so that's shocked the top corrugating roll violently wear, and gradually ground into irregular shapes by the arc, continuous high-speed operation, high flute slowly getting lower teeth, so that the production of cardboard gradually lower towards the standard. Corrugated surface hardness of some low-Corrugated will therefore make the top flute corrugated surface produces Ma Hang and depression, exacerbated the wear process. Since the production line are not always full of pieces of paper away, resulting in uneven wear of the surface Corrugated result Corrugated cardboard in the middle of Au caused blistering degumming. Continuous high-speed low-hardness corrugating roll in a single tooth meshing directional operating conditions will occur due to down corrugated plastic deformation, tilt, twist, increasing ellipticity and beat error, speed up economic impact of corrugating roll life and performance. Corrugated from the above working principle and wear mechanism can be seen, the process of using Corrugated is a process of constantly being worn. Damage to fall into are: Normal wear and tear, wear the top part is the flute; Roller surface of soft, enhanced due to poor paper thin and Ma Hang and depression; Mismanagement resulting in the concave; ? Base soft, roll back caused by poor manufacturing quality corrugated, tilt, twist. How to prolong the life of Corrugated For any grade of corrugated board production line, corrugated roller is always one of the most expensive consumable parts. Its economic performance and service life of corrugated box industry has been an important topic of concern. Improve the wear resistance of corrugating roll, extend the service life of corrugated roll, corrugated board production to lower cost effective way. Currently there is light industry standards, there Corrugated manufacturers of enterprise standards control the quality of the corrugating roll. Tooth surface hardness and hardening depth of the requirements of the following table, completed under different heat treatment the thickness of the corrugated coating hardness, is an effective parameter Corrugated. Corrugated manufacturers of enterprise standards Present, most manufacturers of composite processing, intermediate frequency after quenching or chrome nitride, nitride layer thickness of 0.5 to 0.6?, Chrome thickness of 0.10 ~ 0.15?, Mainstream technology for the medium frequency quenching chrome. To achieve this requirement, the manufacturers now use more material 42CrMo, 48CrMo forging, quenching and meet their hardenability. The life of combined treatment roller 800 ~ 9 million running meters. Manufacturers to gain market leadership, have the material to try out a new steel grades, in the technological aspects of new technologies, the formation of quenching chrome IF, intermediate frequency quenching spray tungsten carbide and chrome laser quenching technique of three main competition, keep abreast of the situation for carton manufacturers choose to provide a variety of programs. Market demand and become the dominant process which direction the market will be the standard of quality and cost to make a choice. After the flow of three process (1) IF grinding stress than quenching Chrome Sand I am an expert from womenleatherbackpacks.com, while we provides the quality product, such as duffle backpack Manufacturer , rolling backpack Manufacturer, backpacks for laptops,and more.
