Inoculant introduction:


     The inoculant can be used as an inoculant for cast iron and ductile iron. Ferrosilicon inoculant is used in metallurgy and machinery industry as an additive and alloying agent for iron and steel and non-ferrous metals. It has the functions of desulfurization, phosphorus removal, deoxidation, degassing and purification, thereby improving the mechanical properties and use effects of materials. Reduce high manganese slag and add it during the smelting process to improve mechanical properties and refine grains.

     Inoculant is a kind of inoculant that can promote graphitization, reduce the tendency of white mouth, improve the shape and distribution of graphite, increase the number of eutectic clusters, and refine the matrix structure. It has a short time (about 5-8 minutes) after inoculation treatment good effect. It is mainly suitable for general conditions in various situations or instant incubation in later stages.

     Inoculation treatment refers to adding a small amount of other substances to the liquid metal during the solidification process to promote nucleation, inhibit growth, and achieve the purpose of grain refinement. Traditionally, adding additives to cast iron is called inoculation treatment; adding additives to non-ferrous alloys is called modification treatment. In essence, the inoculation treatment mainly affects nucleation and promotes the freeing of crystal grains; while the modification treatment changes the growth mechanism of crystals (inhibits growth), thereby affecting the crystal morphology.

The role of inoculants in cast iron:


     1. Strongly increase the graphitization core, refine the graphite, promote the A-type graphite in the gray iron castings, and improve the strength. For the ductile iron castings, the graphite in the ductile iron can be made smaller and rounded, and the spheroidization level can be improved.

     2. It can effectively reduce the undercooling of the molten iron, promote the precipitation of graphite, significantly reduce the tendency of white mouth, reduce the relative hardness, and improve the cutting performance of castings.

     3. Strong anti-decay ability. The anti-decay time is twice that of 75 silicon. The addition amount of silicon barium inoculant is lower than half of 75 silicon inoculant, while preventing the associated spheroidization and recession.

     4. Low wall thickness sensitivity, improve section uniformity, and reduce shrinkage tendency.

     5. The chemical composition is stable, the processing particle size is uniform, and the composition and quality deviation are small.

     6. Low melting point (less than 1300°), easy to absorb melting during inoculation, and there is very little scum.
