Spheroidizing agent

The company introduces production management and quality management system, adopts intermediate frequency furnace for smelting, and the ratio of charge is all controlled by computer.
   ●The chemical composition is uniform, the quality deviation is small, and it can be controlled within ±0.2% of the target value, and the spheroidization ability is excellent.
   ●RE-Mg alloy has high purity and very little oxidized slag.
   ●Spheroidizing treatment has a smooth response and convenient handling.
   ●The spheroidization ability lasts for a long time, and there is no worry of spheroidization decline.
   ●The spheroidization reaction produces less magnesium light and dense smoke, which improves the working environment on the job site.
   ●The spheroidizing agent has complete varieties and specifications, which can meet the different needs of users.

Spheroidizing agent is certain metals or alloys added into molten iron to obtain spheroidal graphite cast iron. What is commonly used in China is ferrosilicon, rare earth and magnesium spheroidizing agent
The rare earth magnesium ferrosilicon alloy is a gray-black solid. It is produced by using ferrosilicon as the raw material and adjusting the mixing ratio of calcium, magnesium and rare earth to a good range to make it react smoothly. The casting thickness of each grade of rare earth magnesium ferrosilicon alloy is no more than 100mm; the standard grain size of rare earth magnesium ferrosilicon alloy is 5~25mm and 5~30mm. According to different purposes, customers can specify special particle sizes, such as: 5~15mm, 3~25mm, 8~40mm, 25~50mm, etc.
