Follow-up inoculants are becoming more and more popular with foundries
In the cast iron industry, a certain amount of inoculant is added to the molten iron before casting, in order to change the solidification process of molten iron and improve the as-cast structure. So as to improve the casting performance, casting more perfect effect. So what is a fluidic inoculant and what are the advantages of an inoculant? So let's see.
Flow inoculant is the inoculant with relatively small particle size (0.2-0.8mm), through the feeding equipment, in the process of pouring molten iron into the molten iron with the flow of molten iron, play the role of inoculation.
The advantages of flow
Compared with the traditional multiple inoculation process in the ladle, the current inoculation process has unique advantages in the current casting production process. First of all, it is the advantage of the amount of inoculant added. The inoculant dose added with the flow method is generally 1/3 of the inoculant dose added in the inverted way. Secondly, inoculation with flow can greatly prevent the adverse effects of inoculation decline on castings. Finally, the graphitization expansion can be used to maximize the self-feeding of the casting.
The nucleation ability of gray cast iron was improved during the inoculation process, and the risk of shrinkage and porosity of molten iron after inoculation was significantly reduced.
Flow inoculation is a highly efficient and energy saving inoculation method. The narrower the particle size range (0.2-0.8mm) of the inoculant with the flow, the better the absorption rate of the inoculant. With the change of Si content, the melting point and effect of inoculant will change. Please adjust and control according to the actual demand.
