During the hot forging process, the surface of the metal billet will form a layer of dense oxide film after being heated at high temperature. If this oxide film is not removed before forging, it will be pressed into the interior of the forging piece, causing surface defects such as pockmarks and cracks, while also accelerating the wear of the mold and affecting the quality of the forging piece and the lifespan of the mold. To address this common problem in the industry, Nanjing Litai Intelligent Technology Co., Ltd. has launched a series of roller descaling machines, with stable and efficient descaling effects, to help forging enterprises improve product quality.
For the hot forging process, optimize the descaling structure
The LITAI roller descaling machine adopts a mechanical descaling structure. The equipment is equipped with one or more pairs of parallel steel wire wheels inside. The upper and lower wheel sets are driven by a power device, and during operation, they generate relative rotational motion. The heated billet is fed into the descaling area through the feeding mechanism. The high-speed rotating steel wire wheels generate relative motion with the surface of the billet, and the oxide scale is removed from the substrate. This structure design is mature and reliable, especially suitable for the surface treatment of round steel, bars, and long shaft-type hot forged parts, and can meet the descaling requirements of various specifications of billets.
The equipment has a compact structure and is easy to operate and maintain. It can be used independently or connected with a heating furnace and forging equipment to form an automated production line, meeting the requirements of batch and continuous production.
Three key features ensure the descaling effect
Stable and efficient, suitable for batch production: The roller descaling machine is made with core components manufactured from high-strength wear-resistant materials. After load testing, it has been verified to maintain stable operation under continuous production conditions. The equipment integrates an intelligent control system, which can monitor the operating status in real time and automatically alert for abnormal situations, effectively avoiding production interruptions caused by equipment failures.
Does not damage the base material, protects the surface of the billet: Different from the impact damage that sandblasting or shot blasting processes may cause to the surface of the billet, the roller-type descaling achieves the removal of oxide scale through the mechanical friction between the steel wire wheel and the oxide scale, having a small impact on the base material of the billet, and is suitable for the production of forgings with strict requirements for surface quality.
Flexible customization, tailored to actual needs: For different production scenarios and material specifications of customers, Laitai Technology can provide customized services. From on-site survey to scheme design, and then to equipment manufacturing, installation and commissioning, a professional team follows up throughout the process to ensure seamless integration of the equipment with the existing production line.
Integrate into the forging production line and enhance overall efficiency
As a provider of comprehensive automation solutions for forging, LITAI's roller descaling machine is not just a standalone equipment but an essential part of the entire forging production line layout. The equipment can synchronize with the heating furnace and forging press, forming a smooth production process. Removing the oxide scale from the source helps reduce subsequent mold wear and the scrap rate of forgings, thereby lowering the overall production cost.
Since its establishment, Nanjing Litai Intelligent Technology Co., Ltd. has always been dedicated to technological innovation in the field of forging equipment. Its products have been applied in various industries such as automotive parts, construction machinery, and standard components. The company is located in LIUHE Economic Development Zone, Nanjing City, and has modern production and manufacturing workshops as well as a professional technical team. It is committed to providing stable and reliable automated solutions for forging enterprises.
