barium silicon inoculants

In many industrial production activities, the demand for Barium silicon inoculants is very large. When we start using inoculants, we must put them in molten iron. Of course, in the process of  order to obtain a better pouring effect, the operation requirements are very strict, and the inoculation is very easy to rot. In order to prevent this, it is necessary to increase the spheroidization rate of the inoculant, thereby improving the flatness of the product surface without unevenness or Sensitive conditions, but also pay attention to the production of elongation, as an important ferroalloy additive, the demand for the cast iron industry is relatively large, and its importance is also quite large, how to choose a good quality inoculant is particularly important!

The method of selecting a good quality inoculant is as follows:

1. The cast iron needs to be cooled throughout the production process, so we need to observe the cooling rate. We can choose the amount of Barium silicon inoculant based on this factor.

2. We need to consider Barium silicon inoculants from many aspects. Barium silicon inoculant suppliers in the entire casting production, we need to carefully observe and understand what requirements, we can also choose

3. Barium silicon inoculant requires a large amount of sulfur in the production process of cast iron, and the amount of additive plays a vital role in the whole production process.　

Barium silicon is non-melting point, the melting point of pure metal such as Fe is 1538 ° C, the melting point of Si is 1414 ° C, the melting point of ferrosilicon is the first place, the liquid phase increases with temperature, the ferrosilicon passes the temperature, After the range is completely melted, the so-called solidus line and 00-1-1, the melting point of the alloy is also related to the composition. Generally, the temperature of the fixed component corresponding to the liquidus is the melting temperature, usually 75 ferrosilicon is used. , temperature 1220 ° C, 50 pieces of ferrosilicon, temperature 1410 ° C, in addition, ferrosilicon contains more impurities in the actual use, resulting in large fluctuations in its melting point temperature, so it should be said that most of the ferrosilicon has a melting point Between 1200 and 1400 degrees Celsius.

Barium silicon greatly increases the core of stone ink, and enhances the type of stone gray iron cast iron, thereby improving the strength, can make the stone ink hard, the 020-3 cast iron casting of ductile iron ball is small in volume and large in roundness. Improve spheroidization, prevent economic recession, have excellent casting performance and good casting ability, wall thickness sensitivity, microstructure, casting hardness is greatly reduced, hardness casting is reduced, processing performance is improved, Barium silicon inoculant is in cast iron As an inoculant and sphere in industry, cast iron is an important metal material in modern industry. It is very cheap, easy to melt, smelt, adding a certain amount of ferrosilicon in cast iron to prevent the formation of iron carbide and promote stone ink and pellets. The precipitation, therefore, ferrosilicon is an important modifier for the production of cast iron (precipitated ink deposits) and nodulizer.
