Description
Technical field
The utility model relates to a kind of device that is used for the horizontal copper pipe base continuous casting, include electromagnetic generator, crystallizer and cold water sleeve pipe, described crystallizer is arranged on the holding furnace, and the inner chamber of crystallizer and the intracavity inter-connection of holding furnace, described cold water sleeve pipe is to be wrapped on the outer peripheral face of crystallizer.
Background technology
From the nineties in last century, the inner screw thread copper pipe with efficient heat transfer characteristic replaces the thin-walled light pipe gradually and becomes the critical material of making air conditioner two-unit (evaporimeter and condenser) heat-transfer pipe, thereby has brought huge business opportunity for international copper pipe processing industry.But, because air-conditioning equipment is very big to the consumption of the energy, and increased the weight of global greenhouse effect, cause the expansion of ozone hole, the environmental protection of the earth is caused extensive damage.Therefore, research and development a new generation has high accuracy, high-cooling property, high cleanliness, light-weighted riffled tube, improve heat exchange performance, promoting air-conditioning equipment to develop towards small-sized, efficient, energy-saving and environmental protection, healthy direction, is another great technical task that the inner screw thread copper pipe manufacturing industry is proposed.Also require us to cast out the casting in bronze base of high-quality, thereby the copper pipe material of high-quality is provided to market.
The casting and roll process that the Finland general company of special elder brother difficult to understand develops is the main method that copper pipe is produced.Cast out hollow bloom by horizontal caster, be rolled into the stretching pipe of certain specification again by the three-roller planetary pipe mill.At present, in the horizontal casting process of copper pipe base, owing to directly contact between liquid metal and the mould, the various defectives (coarse, crackle, groove etc.) that caused cast tube base surface, shortened the service life of graphite jig, in addition owing to be subjected to Temperature Influence, casting blank solidification to organize casting flaws such as circumferentially inhomogeneous, that inside is easy to generate pore, be mingled with.
In order to improve the quality of horizontally continuous casting copper pipes base, patent 02119403.3 and 02149110.0 has proposed to change the structure of crystallizer water jacket, simultaneously electromagnetic confinement coil, stirring coil even single coil excitement are placed in the crystallizer water jacket, simultaneously on the wall of copper water collar, have parallel slit, help magnetic field and see through.Produce experiment and show that there is following drawback in above-mentioned technical method: crystallizer water jacket is changed excessive, influences whole cooling performance; Apply multiple magnetic field simultaneously, structure, equipment complexity, and phase mutual interference; Because tube wall is thinner, the pipe in crystallizer water jacket has substantially solidified and has finished, and quality of tube blank steel improves not obvious.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of device that is used for the horizontal copper pipe base continuous casting is provided at above-mentioned prior art present situation, it can reduce the inside and outside defective of casting copper pipe base effectively, improve interior tissue, make crystal grain homogeneous, refinement, prolong die life simultaneously and enhance productivity and reduce production costs.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this is used for the device of horizontal copper pipe base continuous casting, include electromagnetic generator, crystallizer and cold water sleeve pipe, described crystallizer is arranged on the side of holding furnace, and the inner chamber of crystallizer and the intracavity inter-connection of holding furnace, described cold water sleeve pipe is to be wrapped on the outer peripheral face of crystallizer, it is characterized in that described electromagnetic generator is arranged on the crystallizer between holding furnace lateral surface and the cold water sleeve pipe, and electromagnetic generator is connected with power supply by lead.
As improvement, described electromagnetic generator may be selected to be on the outer peripheral face that annular is placed on crystallizer, and this electromagnetic generator one side is close to the holding furnace lateral surface, and its another side is close to mutually with the side of cold water sleeve pipe.
Improve, its side away from electromagnetic generator of described cold water sleeve pipe also can be provided with the second cold water sleeve pipe side by side again, and this second cold water sleeve pipe is to be placed on the outer peripheral face of copper base pipe.
Improve, it is that the power supply of 5～200Hz is connected that described electromagnetic generator may be selected to be with frequency again.
Compared with prior art, advantage of the present utility model is to adopt electromagnetic generator to be directly installed on the outside of crystallizer (being graphite jig), need not on the copper water collar, to offer the slit, electromagnetic field can act in the interior copper liquid of graphite jig (crystallizer), cause that copper liquid produces diriven motion, make copper liquid in the graphite jig along temperature distribution homogenization circumferentially and longitudinally, obtains tiny equiaxed grain structure, defectives such as minimizing shrinkage cavity, pore; The forced flow that electromagnetic actuation force causes can also be washed away solidification front, purifies solidification front, improves the degree of purity of strand, produces the casting in bronze pipe of high-quality; The initial stage that controlled copper liquid diriven motion can also change pipe is solidified the position, prolongs the service life of graphite jig, enhances productivity, and reduces production costs.
