Description
Technical field
The utility model relates to a kind of copper pipe production equipment, is specifically related to a kind of hollow copper ingot continuous heating.
Background technology
Copper alloy tube is as a kind of raw material of industry, be widely used in the fields such as electric power electric, desalinization, shipbuilding, chemical industry, machinery, papermaking, building, for the manufacture of products such as heat exchanger, component of machine, condenser pipe, waveguide, radiator tube, water pipe, bellows, coiled pipes.Current copper alloy tube generally adopts horizontal casting to manufacture in conjunction with extruded mode.Horizontal continuous casting technology enters molten metal continuously in one end of crystallizer, and molten metal moves and solidification forming to the other end continuously in crystallizer die cavity, then extracts foundry goods continuously at the crystallizer other end.The coagulation forming all at identical conditions everywhere of its product length, has uniformity good, the advantages such as speed of production is fast.
Existing horizontal caster is limited to structure and mould, the column blank that usual casting is solid, in order to be processed into copper alloy tube, also need to carry out from the heating of casting copper post, thimble central hole, hot extrusion, the technological process of cold stretch, the operation of wherein hot extrusion needs the crystallization temperature be heated to by copper ingot close to about 700 DEG C, usually adopts the mode of flame or Ohmic contact heating at present, firing rate is slow, heat energy loss is large, and labour intensity is high.How to develop the hollow copper ingot continuous heating of fast, the energy-conservation and automation of a kind of speed, become technical problem urgently to be resolved hurrily.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides that a kind of firing rate is fast, heat leakage is few and the hollow copper ingot continuous heating of automation.
Technical scheme: for solving the problems of the technologies described above, the hollow copper ingot continuous heating that the utility model provides, comprise horizontally disposed body of heater, described body of heater has through charging aperture and discharging opening, there is between described charging aperture and discharging opening straight-cylindrical horizontal furnace chamber, be provided with high frequency heating coil between described body of heater and furnace chamber, be provided with pair of parallel tubular guide rail bottom described furnace chamber, the internal diameter of described furnace chamber is greater than the external diameter sum of hollow copper ingot and tubular guide rail.
As preferably, lay for the ease of coil, improve the efficiency of heating surface, described high frequency heating coil is established around the outer wall spiral hoop of furnace chamber.
As preferably, in order to temperature curve when heating with copper ingot adapts, the pitch of described high frequency heating coil reduces successively under the direction from charging aperture to discharging opening.
As preferably, in order to improve guide rail water-cooling system to reliability, the two ends of a pair tubular guide rail are communicated to independently water cooling plant respectively; As preferably, in order to reduce energy consumption, simplified apparatus, one end of a pair tubular guide rail is interconnected, and the other end is respectively as the water inlet of water cooling plant and delivery port.
As preferably, scattering and disappearing to reduce the outside of heat in furnace chamber, outside described body of heater, being laid with heat-insulation layer.
During use, copper ingot is sent into furnace chamber from charging aperture, high frequency heating coil is energized, recirculated cooling water is passed in guide rail, be on guide rail at front copper ingot, slowly move forward by under the thrust of the copper ingot of rear feeding charging aperture, simultaneously produce eddy current with responding to high frequency heating coil, in copper ingot, form heat, achieve efficient heating.
Beneficial effect: the utility model adopts specially designed horizontal straight tube dielectric heating oven, coordinate self cooled guide rail, can carry out continuously hollow copper ingot, heating at a high speed, and only have import and export to be in communication with the outside due to body of heater, the passage of its internal elongate and the setting of heat-insulation layer drastically increase the utilization rate of heat energy, meet the needs of copper pipe mass production.
Except technical problem, the technical characteristic forming technical scheme and the advantage brought by the technical characteristic of these technical schemes that the utility model recited above solves, the advantage that the other technologies feature comprised in the other technologies problem that hollow copper ingot continuous heating of the present utility model can solve, technical scheme and these technical characteristics bring, will be described in more detail by reference to the accompanying drawings.

Detailed description of the invention
Embodiment:
As shown in figures 1 and 3, comprise the body of heater 1 with through charging aperture and discharging opening, body of heater 1 has the outline of rectangle to the hollow copper ingot continuous heating of the present embodiment, so that adopt sheet material welding manufacture.There is straight-cylindrical horizontal furnace chamber 2 between charging aperture and discharging opening, in furnace chamber, 2 are provided with pair of parallel tubular guide rail 3, the internal diameter of this furnace chamber 2 is greater than the external diameter sum of hollow copper ingot and tubular guide rail 3, when making hollow copper ingot add thermal expansion and forward slip in furnace chamber, still there is certain gap, avoid card thorax.
As shown in Figure 2, between body of heater 1 and furnace chamber 2, high frequency heating coil 4 is also installed, for the ease of laying and improving the efficiency of heating surface, the outer wall spiral hoop of high frequency heating coil 4 around furnace chamber 2 is established, its pitch reduces successively along charging aperture to the direction of discharging opening, to adapt to temperature curve during copper ingot heating.The end of tubular guide rail 3 is connected with water cooling plant.
The two ends of a pair tubular guide rail can be communicated to independently water cooling plant respectively, with improve guide rail water-cooling system to reliability.Also can adopt U-shaped structure, namely one end of a pair tubular guide rail is interconnected, the other end respectively as the water inlet of water cooling plant and delivery port, to reduce energy consumption, simplified apparatus.Scattering and disappearing to reduce the outside of heat in furnace chamber, the insulation materials such as asbestos can be laid with outside body of heater.
During use, the copper ingot that horizontal caster exports is sent into furnace chamber from charging aperture along guide rail, high frequency heating coil is energized, logical recirculated cooling water in guide rail, the copper ingot put into successively slowly moves forward along guide rail by under the thrust of rear feeding copper ingot, high frequency heating coil in body of heater and copper ingot are responded to and are produced eddy current, form heat, achieve efficient heating in copper ingot.
Below by reference to the accompanying drawings embodiment of the present utility model is described in detail, but the utility model is not limited to described embodiment.For those of ordinary skill in the art, in the scope of principle of the present utility model and technological thought, multiple change, amendment, replacement and distortion are carried out to these embodiments and still falls in protection domain of the present utility model.
