After selecting and determining the vermicular agent, the following must be done in order to obtain vermicular graphite stably: .
1) Accurately grasp the sulfur content of molten iron, only in this way can the amount of alloy added be determined.
2) Determine the processing temperature range according to the selected alloy.
3) According to the selected alloy, determine the appropriate treatment method.
4) Strictly control the amount of molten iron processed.
The treatment techniques used for the above three different types of vermicular agents are very different.
