How to add inoculants

Ductile iron is generally more than gray cast iron casting inoculant, after molten iron incubation, if the pouring time is longer, due to the decrease in inoculation, the amount of pouring inoculant should increase, thin-walled castings are easy to produce white mouth, the amount of ferroalloy of pouring inoculant should increase accordingly, when molten iron contains more slag, casting inoculant once in contact with slag will be wrapped, difficult to melt, so the amount of addition increases accordingly, the amount of casting inoculant added too much, will lead to excessive slag temperature of iron slag and shrinkage of eutectic cattle. If the inoculant is too large, the molten iron cannot be evenly fertilized;The unmelted casting inoculant will also be poured into the cavity, if the block is too small, it is easy to cause oxidation of the slag and easy to produce rot; The volume of casting inoculant block used in the mobile inoculation method is small, generally 0.2~0.8mm, and the addition amount is 0.05%~0.2%; The block size of the inoculation method is generally required to be ≤ 0.25mm, and the addition amount ≤ 0.1%; The remaining casting inoculant is usually added in a block size of 1~10mm, and the amount of addition is 0.1 %% ~0.8% It can be seen that the correct addition of casting inoculant in the casting process can make the effect good and can usefully improve the quality of the casting product, so it is essential to master the addition method of the inoculant.These are some suggestions, I hope to help everyone!We have very good products, and low prices, as long as you have the ferroalloy products you want, please contact usEmail: joanna@aykxgj.com +8616638320060
