When people talk about manganese dioxide, they usually think about its uses in batteries or colorants. I didn’t find that it was also can be used in foundry industry until one of my customer sent me a inquiry about if for their casting riser production.
Thanks to that inquiry, i started to google more information about manganese dioxide’s applications for casting. It seems that manganese dioxide serves as a critical component in the production of riser sleeves, which are an essential part of the casting process by working as a oxidizing agent or a colorant.
In the casting industry, the riser is a very important shaped foundry mold which is made from a series of raw materials consisting of an exothermic material, an oxidant, a refractory etc. It heats the molten metal by burning the heating agent to extend the solidification time of the molten metal, thereby improving the process yield of the casting and reducing production costs. The riser sleeves is widely used in various casting products like high manganese steel, alloy steel, stainless steel, high chromium cast iron, ductile cast iron, gray iron etc.
Oxidant agent is a very important ingredient for foundry as it need to provide necessary oxygen for the exothermic reaction with aluminum. One of the key advantages of using manganese dioxide as an oxidant in foundry applications is its low cost and availability. Foundry manufacturers often seek out cost-effective solutions for their operations, and manganese dioxide's relatively low price with stable oxidizing performance make it an better choice. Additionally, manganese dioxide can be also used as a supplementary oxidant to balance the whole oxidizing performance when a stronger oxidant like potassium nitrate is used.
Working as a overseas sales manganese in QingChong factory, i have much more work to do to be more professional. Let’s work together to be an expert in manganese dioxide marketing.
