Quality control of steel shot and steel grit

Chemical composition

Chemical composition is the most fundamental quality indicator for steel shot and steel grit, which determines their final microstructure and heat treatment effect. The carbon-sulfur analyzer can quickly detect the molten steel material, enabling on-the-spot adjustment at the furnace, and providing testing support for obtaining high-quality molten steel.

Hardness

Moderate hardness is the key for steel shot (grit) to generate ideal acting force during operation, and it has a great impact on work efficiency and abrasive consumption.

Microstructure

The microstructure state of steel shot (grit) determines its anti-fatigue performance. A good microstructure can endow it with higher impact resistance, thus having a longer service life.

Size distribution

Each model of steel shot (grit) is a mixture of large and small particles. The number of particles contained in per unit weight of steel shot (grit) determines the kinetic energy of this size of steel shot (grit). Appropriate particle size can generate moderate kinetic energy and optimal coverage, which is the key to achieving ideal treatment effect.

Fatigue life

The American Ervin life testing machine is used to detect the fatigue life value and kinetic energy of steel shot (grit), which is the ultimate manifestation of the quality of steel shot (grit).
