Description
Technical field
This utility model is related to steel-smelting device technical field, more particularly, to a kind of swinging oxygen side blown converter double-furnace-body double
Smelting device.
Background technology
The principal mode of converter has two kinds of oxygen top-blown converter and electric arc furnace, and the two respectively has pluses and minuses.That is, it is blast-melted
The operation of the metallurgical functions such as desiliconization, decarburization, dephosphorization is carried out by oxygen top-blown converter, or is become through appropriate external refining again
Qualified molten steel.During pure molten iron smelting, the chemical heat produced by reaction between carbon and oxygen has compared with the heat required for steelmaking process
Surplus, so steel scrap can be added as coolant, to reducing energy consumption, it is also possible to reduce steel-making cost.Because oxygen top blown turns
The stove type of furnace is limited, and the steel scrap of addition is generally cold burden, and is mounted in hopper addition, and addition can only account for 15% of metal charge or so.If
Adding amount of scrap steel is further added by, the chemical heat that carbon and oxygen reaction are produced in molten iron will be not enough to maintain to smelt required heat energy.
Electric-arc furnace steelmaking is, with electricity as the energy, can to carry out fusing smelting to full steel scrap.In order to reduce power consumption, also can convert in electric arc furnace
Enter molten iron, strengthen oxygen blast and flux, reduce melting electric consumption.But on the whole, due to electric arc furnace itself the characteristics of, its cost competitiveness
Not as oxygen top blown converter steel making.
With the quickening of world industry process, every year steel scrap amount in the world is continuously increased.In the country of industry prosperity,
Annual steel scrap yield accounts for more than the 50% of year output of steel, at present in China also already close to this ratio.According to current main flow
Steel-making mode, 15% steel scrap can be digested by oxygen top-blown converter, and 35% steel scrap can be consumed by electric arc furnace.Due to electric arc furnace
The smelting cost of steel-making is high, and without competitive advantage in common steel-making, this has just expedited the emergence of intermediate frequency furnace melting waste steel so as to produce steel
The phenomenon of material.Because intermediate frequency furnace only has the function of melting waste steel, do not possess the required decarburization of steel-making, dephosphorization, desulfurization, degassing,
The metallurgical function such as remove to be mingled with, so the steel product quality of production is inferior.But the production cost that intermediate frequency furnace is smelted is lower than electric arc furnace, so
Exist at present or in a large number, prohibit and more than.
So, say to a certain extent, make great efforts to improve the pre-heat effect of steel scrap, and enable steel-smelting device compact conformation section
Save space, more it is environmentally friendly be industry effort all the time direction.
The content of the invention
