Description
Technical field:
The utility model relates to a kind of combined type epoxy coating steel strand wires production line.Especially relate to the epoxy coating steel strand wires that on same production line, can produce two kinds of forms.
Background technology:
The epoxy coating steel strand wires are pre-stress structural materials of a kind of efficient corrosion resisting.The epoxy coating method has two kinds: a kind of is on the surface of steel strand wires and gaps between steel wires applies epoxy resin, is called whole coated steel twisted wire, and coating layer thickness requires 0.38mm～1.14mm; Another kind is that seven steel wires all apply epoxy resin film separately, is called full coat and covers steel strand wires, and coating layer thickness requires 0.12～0.18mm.The coating steel strand wires of two kinds of forms respectively have superiority, and have represented two kinds of different systems in the world, have all obtained application widely, and separately production line equipment and technology are arranged respectively.These present two kinds of production lines all adopt the spray epoxy powder, and powder concn exists certain gradient and inhomogeneities, and has influence on the uniformity of coating.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides whole coating of a kind of energy production and full coat to cover the production line of the steel strand wires product of two kinds of epoxy coatings, and it is the production line that a kind of coating is more even, the coating layer thickness adjustable range is bigger.
The purpose of this utility model is achieved in that a kind of combined type epoxy coating steel strand wires production line, it vertically is linked in sequence successively by pay off rack, hauling machine, supersonic wave cleaning machine, Medium Frequency Induction Heating Furnace, preceding steel strand parting and twisting device, electrostatic powder fluid bed, molten levelling stove with fixed attention, leading portion heat preservation solidification drying tunnel, back segment heat preservation solidification drying tunnel, back steel strand parting and twisting device, bosh, hauling machine and take-up stand and forms, and back steel strand parting and twisting device and back segment heat preservation solidification drying tunnel bottom are provided with traversing guide rail.
This is a kind of combined type epoxy coating steel strand wires production line, can produce the epoxy coating twisted wire product of two kinds of systems.When producing whole applying coating steel strand wires, steel strand wires through Frequency Induction Heating only pass through a twisted wire open and close device, and at about 2/3 place of fluidized powder bed plying, every steel wire has all deposited certain thickness epoxy powder before the plying, powder begins fusing under the temperature of twisted wire, the epoxy resin that melts during plying is come out by extruding from the steel wire gap, add the powder deposition of the about 1/3 fluid bed length in plying back, through consolidation levelling, heat preservation solidification, water cooling, finally obtain Bulk coat from inside to outside.When the production full coat covers steel strand wires, do not pool capital after through the steel strand wires of Frequency Induction Heating by a twisted wire open and close device, 7 steel wires are parastate by fluidized powder bed, consolidation levelling stove, heat preservation solidification drying tunnel, pool capital by second twisted wire open and close device again after the curing, enter the tank cooling at last, obtaining every steel wire all has the full coat of independent coating to cover product.
Because to solidifying the size difference of drying tunnel, the steel strand wires of whole coating method are to enter drying tunnel behind the plying in the process of producing product of two kinds of coatings, size is less, and the speed of service can be very fast; And full coat covers preceding curing of steel strand wires palpus plying of mode, requires the drying tunnel size bigger, is not suitable for quick operation simultaneously.At above characteristics, the utility model adopts two sections drying tunnels: when the production full coat covers mode, use first section separately, steel wire separately solidifies to adapt to, the service requirement of low speed; When producing whole coating method, two sections are used simultaneously, the solidifying requirements when adapting to quick operation.This two-piece design had both satisfied produces actual needs, again can the energy savings cost.
Another characteristics of this production line are to replace the electrostatic sprayer spraying to finish the coating of epoxy powder with the electrostatic powder fluid bed, can obtain more uniform powder concn and coating layer thickness, and 4 pilot jets have been installed additional at first section top of sulfuration bed, can increase the powder concn of this section during startup greatly, thereby strengthen the last powder amount before the twisted wire plying, make between twisted wire center line and the limit silk between the silk of limit powder fill sufficient, simultaneously electrostatic pressure from 10,000 volts adjustable to 5 Wandas, the thickness adjusted scope of powder coating has reached 0.1mm～1.2mm.Consolidation levelling section add the thermal recovery Far-infrared Heating, the temperature of the twisted wire surface attachment powder that can raise fast remedies the temperature that the heat absorption of powder smelting process causes and descends, and reaches the effect of consolidation levelling, is unlikely to heat excessively base steel again.
