More details

ZW Steel Shot has highly praised and well appreciated by domestic end-user and distributor customers for good quality,

competitive prices and good after-sale services.our steel shot production process with advanced technical equipment,perfectly

controlled heat treatments provide it with optimum resilience and resistance to fatigue.

Steel shots are widely used for descaling and descaling of steel workpieces before they are applied. In this case, centrifugal shot

blasting equipment is often used. The shape of the ball and the low hardness make the steel shots do not cause excessive wear

on the equipment. Steel shots are also widely used in the foundry industry. When the workpiece is removed from the mold, the

steel is used to remove the sand from the surface of the workpiece.

The molten steel is melted and then sprayed with a high-pressure water spray gun to form molten steel into steel pellets, and the

formed steel pellets are reheated to be homogenized and then quenched. The quenched steel pellets are dried and reheated and

tempered in the furnace to achieve appropriate hardness, and the tempered steel pellets are sieved through a mechanical screen

to a level conforming to the SEA standard for use in shot blasting equipment. Products of different particle sizes and hardness are

used in different processes such as steel rust removal, surface strengthening and the like. When adding new steel shots, please

observe the principle of a small amount of hard work.

The steel shots are made of selected raw material scrap steel, adding rare metals and best proportioning alloys, and are transformed

into steel pellets by electric furnace smelting, modern equipment production, and after multiple electric heat treatment and automatic

screening, in the process of forming steel grains from liquid metal. Its chemical composition and particle size are strictly controlled to

ensure its mechanical properties meet various uses. Each production process has the strictest quality management. The steel balls

produced are tightly organized, not easy to be broken, uniform in particle size distribution, have appropriate hardness, strong impact

resistance and long service life.
