The present invention relates to a nodulizer for cored wire that adopts an alloy form by smelting. The nodulizing agent consists of magnesium in the form of Mg 2The Si. Gasification and burning of magnesium greatly decreases its amount. Spheroidizing with the same Mg content is stable and increases the specific absorption of magnesium. This spheroidizing process can effectively increase the amount of magnesium in the cored wire.
In a nodulizing treatment process for cored wire, the nodulizing agent is composed of an alloy material, such as magnesium ingots, calcium silicon nodulizer, silica-silicon alloy, or ferric silicon. The latter contains 15 to 28% magnesium, a small proportion of calcium (usually less than ten percent), and five to twenty percent rare earth. The former contains 30 to 80% silicon. In conventional processes, the raw materials are pulverized using the traditional crushing method.
Ferro silicon magnesium alloy, also known as FeSiMg, is a common inoculant used in cast iron. It is used to enhance the mechanical properties of steel, and sometimes contains rare earth elements. Its application has broadened beyond the metallurgical industry to include other applications as well, including the manufacture of ceramic and porcelain materials. Listed below are the main applications of Ferro silicon magnesium alloy inoculation.
Known for its ductile strength and low thermal conductivity, Si-Ba alloy has been used for wires in electronics, wind turbines and other industries. Its core materials include silicon, barium and calcium. Its products are manufactured in China. They are exported to the United States, Southeast Asia and Europe. Their products meet ISO 9001:2008 quality standard. These wires are commonly used for nodulization of wires and cables in the nuclear industry.
Nodulizer for cored wire is made of a magnesium ingot that contains a silica-ferrisilicon compound. It contains a high content of Si, Mg, Fe, and calcium. The magnesium content is relatively constant, and the specific absorption of magnesium is improved with this alloy. It is made from ferrosilicon 75, and has a range of Mg content ranging from fifteen to twenty-eight percent.
The present invention relates to nodulizing agent composition of cored wire. The nodulizing agent composition is made of magnesium ingot and silicon. The alloy forms of these components have higher specific absorption of magnesium. The magnesium in the nodulizing agent is present in two forms: Mg 2The Si and Ca010%. Both the forms have different melting points. The nodulizing agent composition of the present invention adopts the same Mg content and increases its specific absorption rate.
In the present invention, nodulizer for cored wire is a magnesium ingot. It contains 15 to 28% magnesium, 0 to 10% calcium, and 5 to 20% rare earth. Various other nodulizing agents are also used, including silicocalcium and silicon. The nodulizer is used to improve the mechanical and morphological properties of castings. Nodulizer is generally used in the grey casting process, and can be converted to nuclear in a wide temperature range. It has a complete deoxidizing effect, which is superior to that of other alloy deoxidizing agents.
