What to pay attention to during the casting of carburizers

What to pay attention to in the process of casting carburizers:


In the process of casting carbon enhancers, there are actually many problems that need to be paid attention to, if you do not pay attention to a little, it may reduce the quality of the casting product, resulting in defects such as porosity, shrinkage, and shrinkage of the product.


The choice of casting carburizer is very important, and the use of the right carburizer in the right furnace can achieve good results. What level of carburizing agent to choose, the nitrogen content inside is also different, you should choose a low-nitrogen carburizing agent, the content of titanium in molten iron is very low, will not consume a lot of nitrogen, which is easy to increase because of the increase in nitrogen content and a large number of stomata, gas shrinkage and other defects; To find a good carbonizer for graphitization, otherwise it will lead to low absorption rate, slag, and harmful elements affecting the quality of molten iron; Is the addition time of the carburizer, generally can be added in the early stage of casting, the middle stage, the later stage, can also be added at the same time as scrap, in the later stage can also play a role in pretreatment, low sulfur and low nitrogen carburizing agent at this time do not add too much.
