Shot blasting machine manufacturer talk about how to select steel shot correctly in the use of shot blasting machine? How many several types of steel shot of shot blasting machine today.

The following is introduced to you by the shot blasting machine manufacturer:

After purchasing the shot blasting machine, users will want to choose which kind of steel shot is suitable for their machine. First, let's understand that the steel shot is divided into three types: steel shot, cast iron shot and glass shot. The commonly used steel shot of shot blasting machine includes steel wire cutting shot, alloy shot, cast steel shot, iron shot, etc. Cast steel shot is used more often. Steel shot is a high-quality wear-resistant material, with moderate hardness, strong toughness, good impact resistance and long service life.

In the process of shot blasting machine, each steel shot is a process of wear and tear from time to time, so the grain size of each steel shot is changing from time to time. Because the hot spot changes with the grain size of the steel shot, in order to ensure the thermal grain size/ram matching gradually tends to the normal curve. If too much material is added at one time, the appearance of the casting will become fine immediately; If no material is added for a long time, although the appearance quality of castings has improved, the clearing efficiency will be greatly reduced.

(1) Supplementary feeding shall be conducted regularly, and each feeding shall not exceed 10% of the total amount of steel shot. In the process of consumption, the grain size distribution of steel shot shall often be reviewed to ensure that the grain size distribution of steel shot remains unchanged, so as to ensure the liquidation efficiency and the fluctuation of casting surface quality.

(2) In the process of shot blasting machine processing, accurate adjustment and often introspection of the hot shot blasting head are the key elements to ensure the clearing efficiency and waste of capital, to ensure the normal task of the shot blasting separator, to ensure sufficient sand volume, and to develop the power of the shot blasting motor with greater restrictions.

(3) The clearing time can be controlled by removing the sand and oxide skin and exposing the metal body. The extended clearing time can certainly change the appearance fineness of the casting. But it has increased efficiency and cost.

The essence of liquidation is to remove the sand and oxide scale on the surface of the casting and restore the surface of the casting, instead of changing the surface fineness of the casting with a long time of liquidation. It is not appropriate to try to use shot blasting liquidation to obtain a lower surface fineness value, which not only increases efficiency, but also adds cost. It is necessary to improve the quality of the following processes, such as increasing the grain size of sand for molding and core making, and using high-quality coatings, Improve the quality of molding sand, etc.
