ProductsTechnological features in shot using

Technological features in shot using of different size, fraction and hardness.

Varying 3 parameters of shot – size, fraction and hardness- it’s possible to choose the appropriate type of shot to solve any technological difficulties.

Functions of steel and cast-iron shot.

1. Shot blasting and blast cleaning of castings and forgings.

2. Scales cleaning from forged pieces.

3. Elements cleaning of metal constructions.

4. Surface preparation before coating.

5. Strain-harderning shot blasting (blast cleaning).

6. Cutting of marble and granite.

7. Surface preparation of stone.

8. Boilers cleaning of electric power plants from boiler scale.

9. Surface preparation of glass to get flat finish.

10. Ballast filling of tanks.

11. The filler in foundry production in the shell mold and foundry according to consumable patterns.

12. Heavy-weight concrete produce.

13. Well drilling.

14. For rollers ragging of rolling mill.

15. Oil storage tank cleaning.

Selection of shot for definite purposes.

Today the most widespread abrasive is steel shot. Spherical shot presents itself steel particles, made of eutectoid alloyed steel, via KNOW-HOW technology that allows to get optimal performance characteristics.

Grit is the resulting angular particles in the form of irregular polyhedron obtained by means of shot crushing special technology with the subsequent screening.

The decisive criteria of shot quality are durability that is worked out with testing for durability and density that is shot influence on work surface.

Durability of shot and grit is defined with the Ervin Test Machine. This machine simulates the process of blast cleaning.

Density of shot is determined with Almen Test - the effect from shot treatment of treated surface.

Size of shot and grit is chosen in accordance with requirements to surface roughness but the lowest right fraction is applied. The finer shot fraction is, the better the covering level of work surface is, because smaller size of sieve leads to doubling of particles quantity per 1 kg abrasive. All these characteristics provide great potential to improve results and efficiency of the treatment.

Steel shot application ensures less wear of tools, cuts time treatment for achieving necessary quality. Also it dirties work pieces less and significantly reduces consumption of shot.
