Corrugated Board Production Line -- Corrugating Roll
The corrugating roll is the core component of the corrugated board production line. It is a pair of metal rolls that have undergone precision machining and possess a specific tooth profile on their surface. Through mutual engagement and rotational movement, they press the preheated containerboard into corrugated medium with a wavy structure. This pair of rolls typically consists of an upper corrugating rolland a lower corrugating roll, which maintain precise gaps and relative positions to ensure stability and forming quality during the corrugating process.
The Imporatntce of Corrugating Roll
1.The corrugating roll plays a fundamental role in the corrugated board production line, as it directly determines the basic corrugated patterns (such as A, B, C, E, F, etc.) and key physical indicators of the corrugated board.
2. The processing accuracy, surface quality, and operational stability of corrugating rolls directly affect the final output of corrugated cardboard in terms of corrugation height, number of corrugations, flat crush resistance, edgewise crush resistance, and bonding effect.
3.The operational speed, energy consumption level, and the consistency of the produced corrugated board quality of a corrugated board production line are largely dependent on the performance status of the corrugating rolls.
Therefore, the corrugating roll is not a simple forming tool, but an energy conversion and shape-shaping device that transforms raw materials into structural materials with specific mechanical properties. It is the "heart" component of the entire production line, and its condition directly affects production efficiency and product quality.
The Advantages of Tungsten Carbide Coating Corrugating Roll
1. Its hardness is second only to diamond, with excellent wear resistance and abrasion resistance, providing a service life 3-5 times longer than that of chrome coated corrugating rolls; it reduces the cost per square meter of corrugated board and corrugated rollers; it reduces the replacement frequency and cost of corrugated rollers by 65-80% (including downtime and replacement costs); it avoids the frequent wear and tear of related components (such as glue applicators, glue spreaders, and pressure rolls) caused by the wear and tear of corrugating rolls.
2. Due to its excellent wear resistance, the stable corrugated board maintains a consistent corrugation height wear of 0.06-0.08 millimeters during each usage cycle. The optimized corrugation pattern remains almost unchanged, and the amount of glue applied does not increase due to wear on the corrugation peaks. This avoids various common board quality defects, ensuring a consistently ideal quality of the corrugated board.
3. Reduced consumable cost of corrugated board: The carbonized coating corrugating roll can optimize to obtain a corrugated type with lower paper consumption rate; the extremely small wear amount of corrugated height can reduce paper consumption cost by more than 1% compared to chrome-plated corrugated rollers; it avoids various common paperboard quality defects, reducing scrap loss by more than 30-50%.
