Recarburizers Analyse

Because there are many foundry manufacturers using recarburizers on the market, but many of the processes are not very proficient, causing some misunderstandings. Huatuo as a big scale manufacturer with more than 20 years experiences, here we would like to share some of the nomal misunderstanding for the recarburizers.

Here are some misunderstandings.

# 01 Recarburizer with the same chemical composition and particle size distribution is the same

Analysis errors:

Reason: Different crystal structures and external morphologies determine different diffusion speeds and nucleation capabilities, which affect production efficiency and metallurgical properties. The carburizing agents of different substances cannot be compared by chemical composition and particle size.
 

# 02 Carbogen is equal to carburant

Analysis errors:

Carbonizer mainly affects the quality of castings by affecting the quantity and shape of graphite. When the quality of castings is higher, the value of carburizer cannot be completely compared by the price of unit carbonization.
 

# 03 The use of carburizing agent leads to a large tendency of white iron in molten iron, which is prone to poor graphite morphology.

Analysis errors:

The use of recarburizer is mainly to improve the quality of casting products, increase the quality of products, and when used properly can eliminate or reduce the tendency of white mouth and shrinkage of thin-walled castings.

The choice of high-quality recarburizer is the premise. In addition, the stability of the casting can be improved under the proper use method and the amount of use, so as to reduce the production cost and improve the product quality.
