The core technologies of roll texturing shot blasting machine primarily center on texturing precision, operational efficiency, and long-term stability, which can be categorized as follows:
High-precision projectile control technology
The roll texturing shot blasting machine employs variable-frequency drives to precisely control the shot projection speed and the movement speed of the blasting unit; combined with CNC-based precision regulation of the shot flow rate, this ensures that steel grit is projected at high speed onto the roll surface according to set parameters, creating a uniform and controllable textured finish. The core components, such as shot blasting machines, typically employ German technology to ensure stable blasting power, prevent damage to the internal metal fiber structure of the rolls, and simultaneously achieve surface cold work hardening, thereby enhancing contact fatigue strength.
Ⅰ.Full-process automated control technology
The roll texturing shot blasting machine Equipped with a fully automatic PLC control system and a human-machine interface, the unit textures a single roll in just 10–15 minutes. It offers simple, reliable operation with switchable automatic and manual modes, and features a three-color alarm indicator light to provide real-time feedback on equipment status. The particle size can be strictly controlled, ensuring that the surface roughness of the rolled rolls after surface roughening remains stable within the high-precision range of Ra0.5~5μm ± 15%, meeting the requirements for cold-rolled thin plates.
Ⅱ.Adaptive Process and Structural Optimization Technology
It can be adapted to various types of rolls with hardness ranging from HSD93 to HSD98 and diameters within the range of 300 to 1500mm. Through targeted optimization of the abrasive angle and abrasive material selection, it forms micro-pits with controllable depth and density on the surface of the rolls. Some manufacturers are equipped with dedicated process laboratories, enabling them to conduct preliminary process trials based on the customer's roll material and target roughness, thereby significantly shortening the commissioning period after the equipment is put into operation.
The roll texturing shot blasting machine utilizes protective structures such as highly wear-resistant guard plates, significantly extending the service life of critical wear parts and supporting continuous three-shift daily operation; the total investment cost is merely one-sixth that of laser texturing equipment, and the textured rolls themselves offer a longer service life. Equipped with a comprehensive shot-dust separation and dust removal system, it ensures the purity of recycled steel grit while meeting stringent environmental standards for dust emissions, thereby reducing long-term energy consumption and consumable costs.
