Abstract
A horizontal electromagnetic conticasting crystallizer for copper pipe is composed of internal and external layers, three electromagnetic induction coils for stirring, exciting vibration and restricting respectively, magnetic york, and the gap on the external layer.
Description
The present invention relates to a kind of copper pipe base continuous casting electromagnetic crystallizer.
In the traditional copper pipe continuous casting, the solidified structure of pipe is thick, is column crystal substantially, and density is low, is easy to produce segregation, reduces product quality, and casting billet surface is coarse, must lumber recovery be reduced through milling face.
The present invention applies multiple alternating electromagnetic field in horizontally continuous casting copper pipes base process, utilize electromagnetic field to produce electromagnetic stirring force, electro-magnetic exciting force and electromagnetic confinement power, thus the crystal grain thinning tissue, and evenly component distributing is improved surface quality.
The object of the present invention is achieved like this: be wound with electromagnetic stirrer coil and electromagnetic confinement coil and electromagnetic exciting coil around crystallizer wall in the lump, feed alternation (unidirectional and three-phase or two-phase) and pulse current respectively, in crystallizer, produce alternation and pulsed magnetic field, make the liquid metal in the crystallizer when being stirred, be subjected to electro-magnetic exciting force and the effect of electromagnetic confinement power in the effect that is subjected to electromagnetic stirring force.Electromagnetic agitation and electromagnetic exciting make that the solidified structure refinement and the composition of liquid metal are even, and electromagnetic confinement power is improved cc billet surface quality.Can be used alone magnetic field according to the alloy characteristics, also can be used in combination in multiple magnetic field.Crystallizer wall is a sandwich construction, and its internal layer is carbon containing or contains BN or contain SiO
2, or contain Al
2O
3, or contain ZrO or contain the material of SiC, skin is a metal material, and is splitted structure or kerf structure by the skin that metal material is made.That is, the interface of each distinguish or joint-cutting have one section to become certain inclination angle with the vertical axes of crystallizer, enter crystallizer so that alternating electromagnetic field penetrates this layer, make liquid metal be subjected to the effect of various electromagnetic forces.
Concrete structure of the present invention and process are provided by following examples and accompanying drawing thereof.
Fig. 1, Fig. 2 and Fig. 3 are the structure charts of the horizontal continuous casting electromagnetic metal tube billet crystallizer of proposition according to the present invention.Describe specific structural details and the working condition that proposes according to the present invention in detail below in conjunction with Fig. 1, Fig. 2 and Fig. 3.
For making alternating electromagnetic field penetrate crystallizer metallic walls 4, metallic walls 4 is splitted structure or kerf structure, the interface of distinguish or joint-cutting 14 become certain inclination angle with 15 vertical axes with respect to crystallizer, perhaps become broken line, and its angle of inclination is from 0 ° to ± 180 °.The width in its slit can be from 0.001mm to 20mm.In the periphery of continuous casting crystallining wall, be wound with in the lump and stir electromagnetic induction coil 5 and exciting electromagnetic induction coil 6 and constraint electromagnetic induction coil 7, these coils are made by conductive material.For improving the efficient of electromagnetic field, the yoke 16 that has permeability magnetic material to make in the outside of above-mentioned induction coil.These coils can be arranged in crystallizer wall 3 peripheries side by side, also can overlappingly be arranged in crystallizer wall 3 peripheries.Feed the alternating current frequency of stirring coil 5 and be 0.1Hz to 5000Hz with the pulse current frequency that feeds single coil excitement 6, the power frequency that feeds constraint coil 7 is 30Hz to 30 ten thousand Hz.Alternation that is produced or pulse electromagnetic field affact on the liquid metal through the inner chamber 12 that crystallizer wall 4 enters crystallizer, make liquid metal be subjected to mixing power, restraining force and exciting force, thereby reduce contacting and friction, crystallization of refinement crystal grain, uniform temperature and composition of liquid metal and strand and crystallizer wall, improve quality inside and outside the strand.
The present invention is installed on the furnace wall 13 of the middle holding furnace of copper liquid continuous casting or smelting furnace.
