Welcome to Nanjing Dyfeng Small Classroom. In the last issue,

 we talked about the high O in the molten iron in the induction furnace smelting, 

what should I do?

Today, let's talk about the amount of molten iron C that is lower than expected. 

How to solve it?

Usually, when the temperature of molten iron exceeds the equilibrium temperature, 

the reaction SiO2+2C=Si +2CO proceeds to the right, 

resulting in the decrease of C and the increase of Si in the molten iron. 

So don't forget to add C when making ingredients. 

To master the amount of C reduction in our factory, 

make up the amount of C. It should also be reminded that 

the composition of gray cast iron should be adjusted in the order of Mn first, 

then C and then Si.

In fact, in the casting work, 

there will be many problems when the induction furnace is working.

 You can leave me a message for your common problems in the background,

 such as: elephant feet, too low furnace age, constant small furnace problems, 

long smelting time, high power consumption, unknown reasons, etc.

 You can leave me a message and I will let the engineer explain it to you in detail.

Follow me, the youngest girl in the factory. 

Nanjing Difeng will customize a casting solution that suits you. See you next time.
