When you're casting recarburisers, there's a lot to think about. If you don't pay attention, the quality of the casting can go down, and you might get problems like pores, shrinkage, and shrinkage.Choosing the right recarburiser for the job is really important. Using the right recarburiser in the right furnace will get you good results.The nitrogen content in any recarburiser is different. Choose a low-nitrogen recarburizer to reduce harmful substances.
Molten iron has very little titanium, so it won't use much nitrogen. But increasing the nitrogen content can lead to more pores, shrinkage and other defects. So it's important to find a recarburizer with better graphitization to avoid things like low absorption rate, slowness and slag. It'll also affect the quality of the molten iron, so you'll need to find a recarburiser with better graphitisation. You can usually add the recarburiser in the early, middle and late casting stages, or at the same time as the steel scrap. Adding it at a late stage can also play a role in pre-treatment, which can increase the graphite core. Just don't go overboard with the low-sulfur and low-nitrogen recarburizer at this point.
