How to detect the quality of the recarburizer entering the factory

Needless to say, everyone understands the importance of recarburizers, but how to detect the quality of recarburizers? This has always been a distressing problem for many friends who have come into contact with recarburizers. The editor will have a brief chat with you on how to detect the quality of recarburizers entering the factory. Generally speaking, inspections in the factory are used to detect several indicators of recarburizers, such as carbon content, moisture, ash, volatile matter, sulfur content, particle size, etc., but many more stringent companies also need to measure nitrogen content.

The detection of moisture is relatively simple. Everyone can pass the national standard detection method for coal. The volatile content and ash content are the weight disappearance and residue when the muffle furnace is burned to 850 degrees. The carbon is subtracted. Sulfur content is more complicated. Generally, companies do not have inspection equipment, and they use carbon-sulfur analyzers, which are side metal, which is a bit error. The above is the method to detect the recarburizer, I hope it can be helpful to everyone!
