low sulfur low nitrogen recarburizer

There are certain mistakes in this idea. Many purchasers often look at the fixed carbon content of low-sulfur and low-nitrogen recarburizers, and some people even judge the quality of low-sulfur and low-nitrogen recarburizers by the level of fixed carbon. In fact, it's a big mistake. In addition to looking at the level of fixed carbon, you should also pay attention to the absorption rate of low-sulfur and low-nitrogen recarburizers. The absorption rate is good and the quality of low-sulfur and low-nitrogen recarburizers with good fixed carbon content is better!

Attention should be paid to sulfur content when purchasing low sulfur and low nitrogen carburant

Low sulfur low nitrogen recarburizers should also specify the sulfur content according to demand. Not all low sulfur recarburizers meet the production requirements. For example, gray cast iron used in casting is produced. For the promotion of the inoculation effect, the sulfur-increasing operation should be carried out during the gray iron smelting process. In this case, if a low-sulfur graphitized recarburizer is selected, then a sulfur-increasing operation is also required. This is a waste of capital and increases absolute costs. Therefore, it is not a good solution to choose low-sulfur graphitized carburizing agents for the production of gray cast iron. To produce nodular cast iron, the selection of carburizing agents needs to control the sulfur content, but also It is not necessary to choose a recarburizer with particularly low sulfur.

Procurement of low-sulfur and low-nitrogen recarburizers does not necessarily have to be low-nitrogen

As everyone knows more about carburizers, nitrogen has also come into everyone's attention. Now whether they sell carburizers or buy carburizers, if they are talking about carburizers, if they do not mention For smelting gray cast iron, the appropriate nitrogen content can improve the tensile strength of the casting, so there is no need to ask to what extent the nitrogen content of the recarburizer must be low, as long as the recarburizer manufacturer can strictly control the nitrogen content in the recarburizer And provide a true test report, for smelting gray cast iron, you can control the occurrence of nitrogen hole defects.

Through professional low-sulfur and low-nitrogen recarburizer manufacturers' analysis of the matters needing attention when purchasing, we are not serious, and we should purchase according to production needs when purchasing low-sulfur and low-nitrogen recarburizers, because low-sulfur and low-nitrogen The carbon agent process is complicated, so the market price is often higher than other types of carbon enhancers. If blindly purchasing low-sulfur and low-nitrogen carbon enhancers, it will inevitably cause cost waste and increase production costs.
