◆ Advantages
● High Hardness and Wear Resistance: Steel grit is made from high-quality steel, boasting high hardness and strong wear resistance, enabling continuous use under high-intensity working conditions and extending its service life.
● Highly Efficient Cleaning: The hard particles of steel grit can quickly remove rust, scale, and other stains from metal surfaces, improving the surface quality of workpieces.
● Long Service Life: The wear resistance and compressive strength of steel grit result in a long service life, reducing the frequency of abrasive replacement and thus lowering production costs.
● Energy Saving and Environmental Protection: Steel grit can be recycled multiple times, reducing waste generation, and producing minimal dust during use, meeting environmental standards.
● Wide Applications: Steel grit is suitable for surface treatment of various metal materials, especially widely used in industries such as casting, metallurgy, and machinery manufacturing.

◆ FAQ

What types of surface treatments are steel grits suitable for?
Steel grits are suitable for surface cleaning, deburring, shot peening, and coating roughening. They are commonly used for surface treatment of metals such as cast iron, aluminum alloys, and steel, improving surface adhesion and cleanliness.

How to improve the efficiency of steel grits?
Methods to improve efficiency include properly controlling the air pressure and blasting time of the sandblasting machine to ensure the steel grits achieve optimal results during surface treatment. Regularly inspect and clean the equipment, keeping the abrasive and workpiece surfaces clean to improve processing efficiency.

How are steel grits recycled and reused?
Steel grits can be cleaned and recycled using an abrasive recovery system. Regularly remove contaminants and damaged particles from the steel grit to ensure the recycled steel grit maintains good performance and extends its service life.
