Main application of Silicon-manganese alloy

Siliconmanganese is a kind of alloy that consists of silicon, manganese, iron and few carbon or some other elements, it’s a ferrous alloy which is used widely and high production capacity. Its consumption is in second of ferroalloy production. The manganese and silicon in silicon-manganese have strong oxygen affinity, using the silicon-manganese in smelting steel, will produce MnSiO3 and MnSiO4, their melting point are 12700C and 1327 0C respectively, which has the advantages of low melting point, big granule, easy to float up, good deoxidizing effect and so on.
In the same condition, using manganese or silicon to deoxidize separately, the burn out rate are 46% and 37%, but it is only 29% if using manganese alloy to deoxidize. So, it is used widely to smelting steel and its output increases faster than ferroalloy’s, so has become an indispensable composite deoxidizing and alloy additives in steel industry. The silicon-manganese which contains carbon below 1.9% still is used to produce medium/low-carbon ferromanganese and semi-finished products of electro silicothermic process manganese metal.
In the ferroalloy production enterprises, they called the silicon-manganese for steelmaking as commercial silicon-manganese, the silicon-manganese for medium/low-carbon ferromanganese as self-use silicon-manganese and the silicon-manganese for making manganese metal as high silicon-manganese.

Q:What is the difference between industrial furnace masonry and ordinary masonry?
Furnace industry is not generally Mason walls, needs to have a professional operation and rich construction experience, high level of industrial furnace is difficult to get.
Q:What are the companies in the world that are currently engaged in metallurgical furnaces?
Each manufacturer has its own industry and technological advantages.If you say that the performance rankings, turnover, and so on, it seems that no one has done this ranking.
Q:What is industrial furnace masonry?
Plane construction must level, slope construction must find slope,refractory bricks must be selected and processed according to masonry requirements.
Q:Why does the burner of industrial furnace burn occasionally?
The basic structure of the complete ignition system is the ignition device and flameout protection device. The ignition burner includes an ignition electrode and an igniter (equipped with some external type transformer, voltage transformer) through the above 10kV, the ignition electrode spark ignition of high voltage discharge to ignite gas column.
Q:How many kinds of industrial electric furnaces are there?
Electric furnace is divided into four categories: resistance furnace, induction furnace, arc furnace and special electric furnace according to the different ways of electric heating.
Q:What are the combustion equipments used in industrial boilers?
The main auxiliary equipments of the general boiler are: upper coal machine, ash blower, blower, draught fan, economizer, feed pump and water treatment unit. Oil boilers are: oil pumps, burners, tanks and so on.
Q:Brief introduction to repair of industrial furnace
The industrial furnace is the main production equipment in the machinery industry. The repair of industrial furnace directly affects the quality, high yield, long life, low consumption and safe production of the furnace.
Q:What are the advantages of a vacuum furnace?
High degree of integration of mechanical and electrical. On the basis of the improvement of temperature measurement and control accuracy, the workpiece movement, air pressure regulation, power adjustment can be programmed in advance, and quenching and tempering are carried out according to the steps.
Q:Should the industrial furnace shell cool down?
The function of furnace shell is beautiful, protective lining, fixed function accessories and so on.
Q:How to use industrial furnace equipment?
When the furnace is used, the lifting mechanism of the furnace door must be in good condition, and the wire breakage of the steel wire is not allowed to exceed the designated value. The weight should be properly allocated, and the drive department shall be provided with a protective cover.
