The steel shot has good hardness and good cleaning effect. In practical applications, different abrasives should be selected according to the requirements of the workpiece being processed. Due to its widespread application in industry, people are becoming increasingly curious about its usage. Users often mix it with other hybrid applications. Next, I will share with you why steel shot can be mixed with steel grit for use.
1. Starting from the working performance of metals, abrasives are selected based on the surface hardness of steel pipes, the degree of original corrosion, the required surface roughness, and the type of coating. Using mixed abrasives makes it easier to achieve the desired rust removal effect. Steel shot is a commonly used material for processing metal workpieces, with a dense structure and uniform particle size, which can increase the surface pressure of metal workpieces and improve their capabilities. The particles formed from it are heated again for purification and homogenization, and then quenched. After quenching, the pellets are dried in the furnace, then heated and tempered to achieve the appropriate hardness. After tempering, they are divided into 11 grades that meet the standards of the American Society of Automotive Engineers using a mechanical sieve for shot blasting equipment. One characteristic of using steel balls to process metal workpieces is fast cleaning speed. Steel shot can strengthen the surface of steel, while steel grit can etch the surface of steel.
2. From the perspective of the use of metals, steel balls, as the name suggests, are pellets cut from steel wires, which can be divided into stainless steel alloys, ordinary high carbon alloys, and low-carbon alloys according to the different types of steel wires. Steel grit has the advantages of continuous repeated use, long service life, strong adhesion, no damage, and high brightness when cleaning workpieces. The hardness of steel shot is usually 40-50 HRC, and the hardness of steel grit is 50-60 HRC, which can be used on various steel surfaces. Even when used on the surface of corroded steel of grades C and D, the rust removal effect is very good.
The surface treatment of steel pipes seriously affects the service life of pipelines and is also a direct treatment method. Therefore, it is necessary to strictly follow the requirements of the anti-corrosion coating specifications for steel pipe surfaces, explore, summarize, and improve the surface treatment methods for steel pipes.
The above is why steel shot can be mixed with steel sand. This product can be used for sand cleaning of castings and descaling of pipelines, which together improve work efficiency and save work costs. Therefore, if you want to use them in combination, you can refer to this article.
