>The pretreatment agent is a nano-scale material containing silicon carbide rare earth multi-elements. It has a more powerful pretreatment effect than traditional silicon alloys and is suitable for gray cast and ductile iron.
>1. Pretreatment function
> Stabilize the quality of raw molten iron and obtain cast iron with consistent performance.
>, Improve graphite morphology. Gray cast iron can promote the formation of type graphite, and ductile iron can promote the formation of spheroidal graphite. It also has a good effect on processing vermicular graphite cast iron.
>, It can prevent the precipitation of carbides, increase the weight of ferrite, and make the cast iron structure dense. Significantly improves processing performance and makes the cutting surface smooth.
> By adding this product, gray cast iron can generate a large number of eutectic clusters and increase the production temperature (reduce the relative undercooling), which is beneficial to increasing the number of formed graphite nuclei. Make the flake graphite fine, increase the degree of graphitization, reduce the tendency of whitening, thereby improving the mechanical properties. For ductile iron, the increase in crystallization cores increases the number of graphite nodules and improves the nodularization rate.
> This product has strong deoxidation effect and effectively purifies molten iron and steel. It has a good effect on reducing non-metallic inclusions and slag, eliminating shrinkage and porosity, and eliminating subcutaneous pores.
>, eliminate the oxidation factors of molten iron, reduce the oxidation of the furnace wall, and extend the life of the furnace wall.
>2. By using this product correctly, foundries can reduce the amount of pig iron and other alloys added, create castings with more stable and consistent performance, improve mechanical properties, significantly increase yields, and reduce overall costs. cost. Generally speaking, this product is very effective for electric furnace hot metals with relatively low deformation capabilities.

>4. Products Instructions for use
>Adding amount: Usually only .% of the amount of molten iron is added
>Adding method: Melting molten iron in an electric furnace. When dissolving the molten iron into the charge, add it to the bottom of the electric furnace and try not to touch the furnace. wall, and then continue to add charge for smelting. If process conditions permit, the absorption of molten iron will be better within minutes after it reaches superheat.
>5. Packaging and Storage
>Small bags. It can also be packaged according to the specifications required by the user
>The product should be stored in a ventilated and dry place, fireproof, and must not be stored in the open air.
