Sell Ferro Silicon Strontium is a powerful inoculant which can be used in both gray and ductile iron castings. It is particularly suitable for corrosion-resistant cast iron and steam and water pressure gray iron with strict surface requirements.
It is also effective in reducing shrinkage defects and preventing blow-holes. Its low calcium and aluminum content ensures minimal slag formation.
The inoculant contains silicon, zirconium and manganese and can be used for the inoculation of gray or ductile irons. The inoculant can be made by forming a molten mixture of the different constituents or it can be formed as a dry mix or briquette and added to the molten iron bath to be inoculated. It has been found that the addition of strontium results in a superior chill depth compared to commercial inoculants without strontium. Strontium forms sulfides which have lattice parameters very similar to graphite and therefore acts as a potent nucleating agent.
The base alloy for the inoculant is prepared by blending into a submerged arc furnace, quartz and scrap iron to produce a ferrosilicon melt. To this a zirconium silicon or titanium metal and either strontium silicide or strontium metal are added. The zirconium or titanium is added to the molten inoculant before, after or during the addition of the strontium. The inoculant has a low Calcium level and low Aluminum which eliminates the formation of dross during reaction with liquid iron.
Strontium-bearing ferrosilicon is a good inoculant that promotes graphitization, and it is especially helpful in reducing differences of microstructure at different thickness. It can help improve the morphology and distribution of graphite in thin-walled castings, and also refine eutectic clusters. Moreover, strontium-silicon inoculant has strong anti decay ability and can be used for a long time.
The inoculant alloy of the present invention contains silicon, barium, zirconium and aluminum, which can be used to reduce chill formation in gray irons, increase nodule count in ductile iron, and increase machinability. The alloy is easy to prepare industrially and can be used as a replacement for 75% ferrosilicon in many applications.
It is also effective as a ladle addition. It can reduce chill and carbide formation in both gray and ductile irons. It works well in a wide range of casting conditions, including slag-free molten metal. It can also be used to produce high strength and wear resistant cast irons.
A kind of silicon iron nucleating agent that contains strontium and calcium with approximately less than 0.35% of the weight of calcium. It is used in the production of grey and ductile iron. It can be added directly to liquid steel and is highly effective. Its low Calcium and Aluminum level means it produces very little dross compared to other complex inoculants.
It is also one of the most effective promotion elemtnts for eutectic nucleation. It can significantly reduce the undercooling of the eutectic and reduce casting shrinkage defects.
Strontium barium niobate is a special type of ferroelectric ceramic that can be used for a variety of applications. It has a high dielectric constant, a high breakdown strength, and a large energy density. The material is also very easy to process and has a wide range of properties that make it ideal for various applications. It is often combined with other elements to create new materials that have specific characteristics.
Ink for making cathode catalyst layers for solid oxide fuel cells. It needs to be stirred prior to use to ensure an even consistency. Adding to the safety and handling precautions is that it is flammable and must be kept away from heat sources, sparks and flame. It can react with water and oxygen to form toxic and explosive hydrogen gas.
It is suitable for thin-walled chilled sweet ash sulfur cast and water pressure resistance gray iron with strong inking capabilities, and it also has good effect on nickel ductile iron ball (containing Ni14%,Cu6%,Cr2%,Si1.5%), since it reduces white mouth without significantly increasing the number of eutectic. It also has lower allowable temperature and less calcium, low aluminum content, less mold slag, and no pinhole defects in casting.
The North America Ferro Silicon Strontium Inoculant market is expected to grow rapidly over the forecast period, mainly due to rising construction spending and the growth of the electric vehicle (EV) industry. Additionally, the growth of the EV industry is anticipated to boost demand for ferro-silicon grade electric steel.
