What is the use method of spheroidizing agent? Let's learn:
For casting, the use amount of spheroidizing agent will directly affect various properties of molten iron, as well as the size, brand and thickness of castings. It can be seen that it is very important to master the correct use method of spheroidizing agent. The characteristics of molten iron refer to the composition of molten iron, especially the content of sulfur, the temperature of molten iron and the metallurgical quality of molten iron. The spheroidizing agent treatment process mainly includes the shape and size of molten iron ladle, the coverage of spheroidizing agent, etc;
The coverage degree of spheroidizing agent will have a direct impact on the size and shape of molten iron ladle and the height of dam in the ladle. Generally speaking, if the molten iron ladle is thin and high, the coverage of spheroidizing agent will be better if the dam is higher, the oxidation of molten iron will be light, and the addition amount of spheroidizing agent will be reduced;
For molten iron requiring sulfur content and temperature, it shall be used correctly according to the written and specific gravity of spheroidizing agent. Only by correctly mastering the use method of spheroidizing agent can the performance of spheroidizing agent be brought into full play, and the effect of saving dosage and reducing cost can be achieved.
