Definitions

• the main method of steel alloying with steel at present is the use of nitrogen-containing fusion plants, which are obtained from solid nitrogen. And ⁇ radiation
• ferroalloys which are carbon-ferrous manganese, which is used very often and is smelted highly.
• the production of nitrogen-containing carbon dioxide from manganese has very limited use.
• This steel has an unacceptable range of
• the known method does not contribute to the intensification of the process of smelting and nitrogen production due to the low rate of saturation of the oil alloy. Subsequently, the time required for the implementation of the process increases, 20 of which are limited to its production.
• the posed problem is solved in that, in the case of a wear and tear steel, containing carbon, manganese, brown, sulfur, phosphorus, nitrogen, titanium, iron, the following is agreed upon. %: carbon 0.4–1.3 manganese 3–11.5 min. 0.1–1.0 sulfur up to 0.05
• Nitrogen is consumed by the dispersed titanium nitrides, as well as those available after heat treatment of the internal austenite. ⁇ The initial start-up to crippling became the centers of crippling. Congenital and related non-nitrided nitrogen is present in liquid melt and, in turn, is inactive, it does not affect the body. After a temperature of 800- 900 ° C, there is no need to disconnect from the unit due to the small amount of dispersed load in the factory. It is even less related to the desaturation of the waste solution. - Consumer, nitrogen and tsar. Self-enrichment of faults in crystalline lattices of the dispersed atoms of the process of the formation of equilibrium springs.
• the basic task of the invention is also the creation of a high production method of emitting steel, which ensures a reduction in the cost of production

• Increase in partial nitrogen pressure up to 0.3 0,3 Pa with -II- is achieved by an increase in the rate of saturation of the dopant and an increase in the concentration of nitrogen in the alloy, although there is a slight reduction in pressure. Further increase in pressure
• Such nitritides which are found in alloyed alloys in the form of solid particles, will be subject to commercialization costs when the supplies are grinded.
• the loss of steel prices from commercialization centers decreases by 5% in the case of the loss of profitability and the decrease in the rate of collapse. This improves the overall performance of the refinery in general.
• nitride-forming elements to the 25th nitrogen-saturated alloying additive in a finely divided form with a particle size of about 4 millimeters.
• particle size is less than I mm, they are fully vaporized in the plasma and do not fall into the alloy. For particle sizes larger than 4th they do not accelerate to melt to its full depth during the time of their stay in
• nitrogen is supported in such a way that a mixture of nitrogen was specified in the alloy. It is also necessary to accelerate the saturation stage of the alloy with nitrogen, so that the partial pressure in the melting tank rises to 0.3 IA, and then 5 reduces to the preset level. Further, there is a mixture of both popular alloys - an illegal steel mine and a rich nitrogen alloy. For this, an unalloyed steel base is available that is around 0 to about 0.7 of the mass of the melts and adds the whole mass of saturated nitrogen melted
• the maximum nitrogen content in the alloying addition and the atomic pressure is higher than that required for the unit to be consumed. Therefore, the mixing leads to the following: they take the entire mass of the molten alloying
• Oxygen desulfurization constituent for this example it is equal to 1.35;
• condition (I) which for this example is written as follows:
• the deliberate use of a more successful and successful invention may be made using 3 5 use in the manufacture of high manganese-based products.
