In order to produce qualified ductile cast iron, except the suitable casting process, the different kinds of elements in molten steel are important to ductile cast iron....

Calcium ferro cored wire an indispensable deoxidizer and slag remover during steelmaking. However, how to improve the effect and yield rate of Calcium ferro cored wire has always troubled steel manufacturers. In fact, the factors affecting...

Silicon-barium (calcium) inoculant is a massive metallurgical material made by mixing silicon powder and barium powder in a proportion according to demand, and then steelmaking in a high-temperature furnace. It is an additive in the casting...

In the selection of inoculants, the following items should be noted: 1. Reduce the depth of white mouth. RE and Ca series inoculants are used for low-sulfur molten iron; carbon-based or graphite is used for high-sulfur molten iron. 2. Reduc...

The selection of spheroidizing agent should pay attention to the following items: 1. Magnesium content of 4%, 5%, 5.5% belongs to low-magnesium spheroidizing agent, and RE is between 1% and 2%. It is mostly used for smelting in intermediate...

Metal silicon powder is powdered silicon powder produced by grinding and processing metal silicon (industrial silicon). Metallic silicon is also called crystalline silicon or industrial silicon, and its main use is as an additive for non-fe...

In the cast iron industry, a certain amount of inoculant is basically added to the molten iron before pouring the molten iron to change the solidification process of the molten iron and improve the as-cast structure. So as to improve the pe...

There are many types of inoculants, and the more commonly used ferroalloy inoculants are 75 ferrosilicon inoculants. Nowadays, the demand for thin walls in castings is getting higher and higher, and the requirements for the use of inoculant...

silicon-barium inoculant is actually not a ferroalloy. It is actually a composite multi-element alloy made by artificial smelting. The silicon and barium in the silicon-barium inoculant can be matched and combined in a targeted proportion t...

Cast iron has a history of more than 40 years. It is mainly used in wear-resistant materials and building materials. With the upgrading of cast iron production technology, the silicon-barium inoculant was born. The silicon-barium inoculant...

Silicon and iron can form silicides such as Fe2Si, Fe5Si3, FeSi, FeSi2, etc. These are the main components of ferrosilicon. The silicon in ferrosilicon mainly exists in the form of FeSi and FeSi2, especially FeSi is relatively stable. ...

The surface treatment methods of magnesium ingots vary with the length of storage time.The most commonly used method is pickling to remove impurities on the surface of magnesium ingots and to increase anti-oxidation film layer....
