The manufacturer teaches you to choose the hardness of the steel shot for strengthening steel shots.
The quality of the steel shot is more critical than its hardness, and the hardness is poor or loose, which affects the effect. The good steel shot can improve the hardness and compactness during the continuous slamming process. Steel shots produced by Shandong steel sand steel pill manufacturers can meet different hardness requirements, and because of the bearing steel material, it is more durable and wear-resistant.
In the past few years, as the price of steel in China has risen all the way, as the main raw material of steel pellets, the price of scrap steel has also risen sharply. However, in the near future, the price of steel has started to fall, and the price of steel pellets has also been sold. The decline, thus forming a high-priced acquisition of raw materials, but the low-cost sale of finished products in the market pattern, is the majority of steel pill manufacturers' profit margins all the way down. Because of the blind production of some manufacturers, many technical indexes are not in place, the quality of steel shots has not been well guaranteed, and there has been a mixed situation in the steel pellet market. However, with the rapid recovery and development of the steel pill market in recent years, the steel pill market has now returned to normal. In recent years, China's industry has developed rapidly, and the steel pill market has been gradually driven, and the market prospects are promising.
The steel shots and iron shots used in shot blasting are not really pills in the true sense. It is precisely a small steel wire or a small steel stick. It only looks like a ball after a period of use. The so-called sandblasted sand is said to be worn. It is just a river sand, and it is no different from the construction. It is only sieved with sandblasting, with less mud and particle size specifications. Of course, some industries are also different. For example, the shipbuilding industry uses real metal shots for shot blasting and metal ore (not river sand-quartz sand) for sandblasting.
