Description
Technical field
The present invention relates to a kind of torpedo tank car automatically to add and get lid arrangement.
Background technology
China is second-biggest-in-the-world energy-consuming state at present, is also that second-biggest-in-the-world CO2 discharges state simultaneously.The steel industry of energy intensive more than 20%, occupies the first in the world in continuous 9 years in Chinese output of steel continuous 5 years amplification, but its energy consumed and the carrying capacity of environment that causes thereof have also reached 10% of whole industrial total amount all.Therefore alleviate the energy utilization rate that first China energy consumption and environmental pressure will improve China Steel industry, development energy-saving circulating economy is the only way of Chinese Iron & Steel Enterprises.In order to improve the market competitiveness of enterprise, iron and steel enterprise must be changed to science and technology-oriented, energy-saving industry gradually by former large-scale production.The competition of iron and steel enterprise is from now on exactly the competition of enterprise energy utilization rate.
As the novel concept proposed in recent years, essence is that high efficiency of energy utilizes, the problem of development of clean energy, and core is the innovation of energy technology and energy-conserving and emission-cutting technology, industrial structure innovation and production technology innovation etc.This Economic Development Mode is different from the model of rough increasing economic of traditional iron and steel enterprise; it is the problems such as global warming, crisis of resource and the environment produced under process traditional economy growth pattern, provides a kind of mode that can solve the conflicting practicable with human social.
The main production process of iron and steel enterprise is ironmaking (ironworks)-steel-making (steel mill)-continuous casting (continuous casting workshop)-product (section bar factory, board mill etc.).In whole production process, the technique circulation between each workshop can reduce along with temperature, energy loss.And the every temperature of procedure to product has strict requirement, in order to ensure the normal production of every procedure, the energy resource consumption by preceding working procedure is a large amount of is only had to improve temperature.The energy dissipation of steel product is fast, and along with the rising of temperature, energy ezpenditure can be doubled and redoubled, so the heat preservation energy-saving level of inter process directly can have influence on the production cost of product.
In current domestic iron and steel enterprises, iron-smelter generally adopts ladle splendid attire molten iron, by hot-metal ladle and carriage, molten iron is transported to steel mill's desulfurization station and carries out desulfurization and skim, and is then lifted to converter station by driving and molten iron is blended into converter smelts further.According to different product structures and programming and distribution, wide apart between iron-smelter and steel mill.In older enterprise, the distance between Liang Ge factory has more than 5 kms usually; In recent years newly-built enterprise, at 500 to 1000 meters not etc., and this section whole process is outdoor, there is very large potential safety hazard for the distance of Liang Ge factory.
It is unlimited that steel mill's ladle all at present wraps mouth in transportation, and molten iron directly contacts with air.Because molten iron and air exist the temperature difference, constantly there is thermal convection current in both, the heat of molten iron large losses, and very easily security incident occurs at sleety weather.By carrying out tracking measurement to many enterprises, molten iron in ladle from blast furnace out temperature be about 1500 DEG C (molten iron mean temperatures), when ladle runs to desulfurization station, temperature has been reduced to about 1340 DEG C (molten iron surface temperatures), sometimes lower.To sum up, ladle runs to molten iron temperature the process of desulfurization station from blast furnace and on average reduces by 120 DEG C.Liquid steel temperature often reduces by 60 DEG C and is equivalent to molten iron per ton and dispels the heat 10000Kcal to air, and be equivalent to the combustion heat release of 1600 kilograms of standard coals, such energy loss is very large; Ladle is opened wide and is distributed a large amount of flue dust also reduces equipment service life to environment simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, effectively avoid fish torpedo ladle automatically to add at the torpedo tank car of course of work heat loss and get lid arrangement.
Technical solution of the present invention is:
A kind of torpedo tank car adds automatically gets lid arrangement, it is characterized in that: comprise steel structure frame, cantilever is be connected turnably up and down by bearing pin and steel structure frame, the lifting hydraulic cylinder that cantilever moves up and down with promotion cantilever is connected, the swing arm of cantilever leading section and torpedo cover is that pivot point is connected with pivoting support, one end of oscillating motor is fixed on cantilever, and the expansion link front end of oscillating motor is connected with the swing arm of torpedo cover; Torpedo cover comprises the lid that bottom is lined with resistance to material, and lid is provided with reinforcement, and lid is fixed with swing arm.
Lifting hydraulic cylinder one end is connected with steel structure frame by crotch shape brace, and the expansion link front end of lifting hydraulic cylinder is connected with cantilever.
Swing arm is provided with the engaging lug be connected with oscillating motor.
The present invention is rational in infrastructure, can reduce widely fish torpedo ladle in transportation heat scatter and disappear; Reduce the discharge of noxious fume, improve air ambient; The slagging scorification of effective control fish torpedo ladle tank mouth, improves molten iron utilization rate; Improve the service life of the resistance to material of torpedo tank liner; Rainy season rainwater can be prevented iron water mitigation in fish torpedo ladle; Simple to operate, reduce costs.
