Description
Technical field
The present invention is the online hot dip copper zinc alloy of a steel cord production technology, is specifically related to a kind of steel cord direct heat copper facing zinc alloy environment-friendly production process and device.
Background technology
Steel cord copper coating zinc alloy can improve it and rubber is asked bonding force.The steel cord production process of copper facing zinc alloy comprises the thermal treatment of steel cord and two relatively independent parts of copper facing zinc alloy at present; The thermal treatment of steel cord mainly comprises heating austenitizing and two operations of isothermal thermal treatment, and the copper facing zinc alloy comprises electrolytic degreasing, pickling, electro-coppering, electro-galvanizing, diffusion annealing and multiple tracks washing step.In the austenitizing operation, still be the furnace for gaseous fuel heating no matter adopt special atmosphere oven, all there is the pollution from exhaust emission environmental problem in production process.In addition,, adopt the way that increases process furnace burner hearth length (austenitizing process furnace and isothermal annealing stove), not only take bigger production space, and energy consumption is also big for obtaining higher wire travelling speed.And with plating method copper facing zinc alloy operation many (comprising electrolytic degreasing, pickling, electro-coppering, electro-galvanizing, diffusion annealing and multiple tracks washing step) not only, and production process exists a large amount of alkalescence, acidity and heavy metal ion sewage discharge problem.In addition, electro-coppering, electro-galvanizing solution composition and technological parameter fluctuation can cause copper facing and galvanized layer thickness to change, copper zinc alloy composition of layer after the change diffusion annealing, and then influence the bonding force between steel cord and rubber.
Summary of the invention
Technical problem to be solved by this invention is: to the shortcoming of above prior art existence; Propose a kind of steel cord direct heat copper facing zinc alloy environment-friendly production process and device, can make existing production line contraction in length 30-50%, production process does not have waste gas and heavy metal ion sewage discharge; Allow higher wire travelling speed; The copper zinc alloy Coating composition is stable and be easy to control, and energy consumption reduces, and production cost descends.
The technical scheme that the present invention solves the problems of the technologies described above is: steel cord direct heat copper facing zinc alloy environment-friendly production process and device, its Production Flow Chart and operation are electrolytic degreasing → wash → be coated with plating assistant agent → oven dry → hot dip copper zinc alloy and austenitizing → precooling → isothermal processes.Compare with present production technique (austenitizing → isothermal processes → electrolytic degreasing → washing → pickling → washing → electro-coppering → washing → electro-galvanizing → washing → diffusion annealing); The application is through saving multiple working procedures such as pickling, electro-coppering, electro-galvanizing, diffusion annealing, washing; And adopt measures such as hot dip copper zinc alloy and steel curtain line austenite chemical industry preface unite two into one, steel cord production line length is significantly shortened.
The application bathes as the steel curtain line austenite heating medium through the copper zinc alloy that adopts the high temperature resistance furnace heating; Steel curtain line austenite heat-processed is not contacted with direct atmosphere; Production process need not to prevent its surface oxidation decarburization, so can not produce exhaust gas emission with protective atmosphere.
The application replaces present gas phase heating medium through adopting copper zinc alloy to bathe, and the steel curtain line austenite heating coefficient is significantly improved, thereby when process furnace length is identical, allow higher wire travelling speed.
The application prepares the plating+thermal diffusion technology of copper zinc alloy through adopting technological electro-coppering, electro-galvanizing and the diffusion annealing that substitutes in producing at present of hot dip; Make steel cord production process not have copper, the sewage discharge of zinc heavy metal ion, ensured the good environmental protection Harmony that the steel cord is produced.
The application is through adopting the hot plating technology temperature at the technological copper zinc alloy coating for preparing of 930-1050 ℃ hot dip; Make in the hot dip process copper zinc alloy form certain thickness diffusion layer through the room flooding mechanism easily with between the carbon steel steel wire, thereby guarantee that copper zinc alloy coating and carbon steel steel wire ask to have that good interface combines and higher interface binding power.
Plating+thermal diffusion technology prepares copper zinc alloy coating, guarantees that Coating composition and inhomogeneity qualifying point thereof comprise electro-coppering thickness, electro-galvanizing thickness and diffusion annealing process (temperature and time).In contrast to this, the application is through adopting the hot dip technology, and Coating composition and homogeneity thereof are bathed decision by copper zinc alloy, guarantee that the qualifying point of coating of steel wire cord quality has only one, thereby the quality of coating ratio are easier to.
The application prepares copper zinc alloy coating through adopting the hot dip technology generation for plating+thermal diffusion technology; And take the measure etc. that unites two into one of hot dip copper zinc alloy and carbon steel steel wire austenitization; Electro-coppering, electro-galvanizing, diffusion annealing and multiple tracks washing step in the present production process have not only been saved; Reduce electricity consumption water cost, saved soda acid and heavy metal ion cost of sewage disposal, and production line shortening having reduced space hold; Reduced depreciation of fixed assets etc., thereby made the application's production decision have lower production cost.
