The Role of Rare Earth Elements in Spherical Agents
Improve the thermal stability of the mechanical properties of the alloy: rare earth elements are effective alloying elements to improve the heat resistance of rare earth magnesium alloy, which can improve the high temperature strength and high temperature creep resistance of Mg alloy. The diffusion coefficient of rare earth in magnesium is small, which can slow down the recrystallization process and increase the recrystallization temperature, increase the aging effect and the thermal stability of the desoluble phase, pin the grain boundary of the high melting point rare earth compound, hinder the dislocation movement, and improve the high temperature creep resistance.

Effect of Nodularizing Agent on Graphitized Cast Iron
The effect of spheroidizing agent on the structure of graphite cast iron: spheroidizing agent can improve the structure of cast iron, and there are two kinds of spheroidizing agent and spheroidizing agent. Under the action of the spheroidizing agent, the graphite will be spherical instead of flake when the iron-carbon alloy is solidified, and this spherical graphite is more uniform and fine, and the distribution is more uniform. The ferrite structure in cast iron has also been greatly improved, short spherical graphite can refine the ferrite grains, so that the grain spacing is more uniform, so as to improve the overall performance and hardness of cast iron.
Advantages of carburant
Advantages of carburizer: carburizer is widely used, and has certain applications in steelmaking, forging, refining and other fields. Its physical properties are relatively high, which can achieve the advantages specified in the production process faster. In the field of pig iron, carburizer can also avoid pig iron at low temperature and white iron. Under specific application conditions, carburizer has more and more advantages, which can reasonably reduce the duration of carburization and improve the actual effect of carburization, it also has the advantages of increasing the amount of waste steel, arranging network resources reasonably, and reducing costs.
The difference between silicon carbon alloy and silicon carbide
Silicon carbon alloy and silicon carbide are two different materials, which are obviously different in composition, structure, performance and application.
What is the role of casting carburant
Improve the strength and hardness of castings: Carburizer can increase the carbon content of castings in casting, thereby increasing the strength and hardness of castings
What are the advantages of inoculant in cast iron
Inoculant is a special alloy added in the smelting of cast iron. Its main function is to improve the solidification structure and performance of cast iron, and to improve the quality and mechanical properties of castings.
Principles of Spherical Agent Selection
The requirements of the spheroidal agent on the cast structure of the casting: low rare earth spheroidal agent is selected for the cast ferrite spheroidal graphite cast iron, and the spheroidal agent containing copper or nickel is selected for the cast pearlite spheroidal graphite cast iron;
How to choose and buy inoculant to see good or bad
When purchasing inoculant, the quality of inoculant should be investigated. Good inoculant is usually uniform in strength and accurate in physical and chemical indexes. When purchasing inoculant, samples should be asked from manufacturers as much as possible and tested by laboratories. If there is no laboratory, samples of inoculant should be used for testing. The quality of inoculant should be judged by tests and trials;
