Cold Roll Surface Texturing Machine
- 产品详情
The KEEJOO high quality Cold Roll Surface Texturing Machine is a device that uses a high-speed rotating shot blasting machine to accelerate steel grit and then project it onto the surface of the roll to form a uniform rough surface. It is mainly used in the production of cold-rolled thin plates to improve surface quality.
Feature
The Automatic Cold Roll Surface Texturing Machine Steel shot is rapidly projected onto the surface of the rolls by a blast wheel to form a micro-rough structure. functions include:
Surface treatment: Countless strengthened sand surfaces are produced on the surface of the rolls through shot blasting impact, enhancing the adhesion and coating performance of the sheet surface.
Controllable parameters: Shot velocity 60-100 m/s, coverage rate 100%, and roughness Ra value controllable.
Applicable scenarios: Cold-rolled work rolls and support rolls, extending service life, suitable for the production of high-end plates such as automotive plates and home appliance plates.working principle
The Automatic Cold Roll Surface Texturing Machine accelerates the steel grit to the set speed through the blast wheel and projects it directionally onto the surface of the rolls, creating countless and disordered strengthened rough surfaces on the roll surface. This coarse roll with a rough, uniform surface and high hardness can be directly used for the rolling and leveling of cold-rolled thin plates (steel strips), which can increase the rolling speed, improve the shape, reduce surface scratches and is conducive to overcoming adhesion.
Advantage
High efficiency and uniformity: By using high-speed shot blasting impact, a uniform roughness can be quickly formed on the surface of the rolls, featuring high processing efficiency and good repeatability.
Low comprehensive cost: The cost of The Automatic Cold Roll Surface Texturing Machine purchase and operation and maintenance is much lower than that of processes such as laser or electric discharge roughening, demonstrating outstanding economic efficiency.
Strengthening the roller surface: The shot blasting process not only forms roughness but also generates compressive stress on the roller surface, enhancing the fatigue strength and durability of the rolls and prolonging their service life.
Easy operation: Modern shot blasting machines have a high degree of automation, and process parameters (such as shot blasting volume and speed) are easy to control, ensuring a stable and reliable production process.Technical Parameters
