High-silico Silicon Manganese

High-silico Silicon Manganese, also called low carbon silicon manganese. It is a high-purity alloy with very low harmful and impurity elements (C, S, P, Fe). It is a good deoxidizer in the steelmaking process. High-silico Silicon Manganese alloy is an intermediate product of smelting metallic manganese. Compared with ordinary silicon-manganese, the deoxidation and reduction in the steelmaking process are increased by 2-3 times.

 

 

First of all, the name is different from ordinary silicon manganese.

 

Because High-silico Silicon Manganese is different from ordinary silicon manganese in element composition. High-silico Silicon Manganese generally contains high silicon (Si> 22%) and low content of impurities Fe, C, and P (C <0.5%, P <0.15%).

 

Secondly, it is the difference between the raw materials and equipment parameter conditions and ordinary silicon manganese.

 

To produce high-silicon silico manganese that meets the specifications, the standard for manganese raw materials entering the furnace is much stricter than ordinary silico manganese. The manganese raw material must be high-grade (Mn> 42%) manganese ore with low phosphorus and iron.

 

On the other hand, the smelting of High-silico Silicon Manganese requires a higher reduction furnace temperature than ordinary silicon manganese. In other words, it is necessary to grasp the blast furnace temperature required for reducing silicon and the problems of burning and volatilization of manganese with a lower boiling point.

Application Range of High-silico Silicon Manganese

 

Internationally, High-silico Silicon Manganese is used extensively when smelting stainless steel and special low-carbon steel. Many large domestic steel companies in China have also begun to attach importance to low-carbon, High-silico Silicon Manganese with high main element content and low impurity content. In the trend of improving product quality and reducing costs, High-silico Silicon Manganese will soon be used as a deoxidizer for steelmaking as in the world.

 

Nowadays, High-silico Silicon Manganese (low-carbon silicon-manganese alloy) is widely used in the smelting of stainless steel and special low-carbon steel, such as the United States, Britain, Norway, Japan, Spain, India and other countries. South Korea's Posco alone uses 35,000 tons of high silicon silicon manganese (low carbon silicon manganese alloy) every year.

 

In China, some steel mills have used High-silico Silicon Manganese (low-carbon silicon-manganese alloy) instead of ferrosilicon and expensive low-carbon ferromanganese as deoxidants for steelmaking. For example, a steel plant uses low-carbon high-silicon silicon-manganese alloys with Si> 25% and C <0.5% instead of C <0.7% low-carbon ferromanganese to produce wire steel and Q195 steel. The cost is greatly reduced and the product quality is stable.

 

Many large domestic iron and steel enterprises in China are interested in the excellent properties of low-carbon, high-silicon, silicon-manganese, high main element content, and low impurity content. It can be expected that under the trend of improving product quality and reducing costs, Chinese domestic steel companies will soon use High-silico Silicon Manganese (low-carbon silicon-manganese alloy) as a deoxidizer for steelmaking as soon as the world.
