Snoidizing agent manufacturer: Snoidizing agent in the application of molten iron
Based on the percentage of the total weight of the molten iron, the total content of the spheroidizer used by the spheroidizer manufacturer is 1.1%-1.5% by weight of the molten iron. The amount of spheroidizer added is influenced by four factors: the spheroidizer itself, the properties of the molten iron, the size of the casting, the thickness of the thin wall, the grade of the ductile iron and the spheroidizing process. In the production of nodular cast iron, the dosage of nodular agent directly affects the overall performance of nodular cast iron and the production cost of nodular cast iron.
When using a spheroidizer, an important issue is the amount of spheroidizer used. Many spheroidizer manufacturers are not sure, which can lead to excessive spheroidization or spheroidization problems. So how much is appropriate?
For castings, the amount of spheroidizer directly affects the properties of molten iron, as well as the size, brand, thickness and other issues of castings. Therefore, it is very important to use the spheroidizer correctly. The characteristics of molten iron refer to the composition of molten iron, especially the content of sulfur, the temperature and the metallurgical quality of molten iron. The treatment process used by the spheroidizer manufacturer mainly includes the shape and size of the ladle and the coverage of the spheroidizer.
For the size and shape of the ladle, the coverage rate of the spheroidizer directly affects the coverage rate of the spheroidizer. In general, if the ladle is thin and tall, the dam will be taller and will be covered with spheroidizer. Even better, the molten iron will be slightly oxidized and the amount of spheroidizer added will be reduced.
The length of time that the spheroidizer stays in molten iron will also affect the quality of production. If the temperature of the molten iron is higher, the stirring effect in the electric furnace will be better. The diffusion rate of a spheroidizer is directly related to its density. Therefore, there are many factors that will affect the production quality of the spheroidizer, but the selection of the appropriate size of the spheroidizer is a problem that can not be ignored in the production.
For the molten iron with sulfur content and temperature required by the spheroidizer manufacturer, it should be used correctly according to the writing and specific gravity of the spheroidizer. Only by correctly understanding the method of spheroidizing agent, can we give full play to the performance of spheroidizing agent, save resources and reduce cost.
