Manufacturing Process of Composite Cored Wire

The description of the composite cored wire manufacturing process .

The composite cored wire is also called solid&flux cored wire . which is used in steel making and metallurgy.

The steel coil is taken by a crane or loader and hung on the expansion of mandrel of two-position uncoiler ,see the figure-1 From the loading position, the uncoiler is rotated 180 degrees ( working position), the front end of steel strip is fed into the pull rollers, and then filled into the first stand of the pre-forming unit of the forming mill and passes through all the stands at a creeping speed .

To ensure a continuous steel strip forming process, the rear end pf the coil is joined by welding (see the figure-1)to the front end of the subsequent coil.

The steel strip is formed into a tubular billet in a forming mill , the Powder is fed from removable bins-containers through a hopper-feeder and dispenser to a preform having a U shaped shape,meanwhile , the calcium wire is fed through a uncoiler and guiding unit to the U-shaped tubular.

Next the composite cored wire is compacted by the subsequent stands and welded by the HF welder.

In the manufacture of composite cored wire ( 2 powders and 1 calcium cored wire).Two dispenser are used , setting the dispenser#2 to the specified flow rate of the first powder is performed by starting the line ( with the dispenser#1 closed for the second powder),bringing it to operating speed,stopping and weighing 1 per meter of wire,as well as weighing its contents,After obtaining the required weight of the first powder in 1 line meter of wire,the dispenser#1 for the second powder is open,and above procedure is repeated to determine the total filling the the wire .

After obtaining the required weight for the 2 powders in 1 meter of wire . close the dispenser #1 and dispenser 2# ,and feed the calcium wire into the U-shaped tubular ,bringing it to operating speed,stopping and weighing 1 per meter of wire as well as weighing its calcium wire. So that the required weight of calcium wire per in 1 meter wire is obtained.

After welding the composite cored wire, the the welded composite cored wire move to the calibration unit, it is reduced to the required diameter by the calibration mill.

From the calibration mill, the compsoite cored wire enters the length meter and then through cored wire laying unit to the winding device , the expansion mandrel of the winding device has restrictive cheeks( one of them is removable), providing the necessary width of bunch.

After winding a bunch(coil), the cored wire is cut at signal of the tracking roller sensors of length meter,perform binding(strapping) of the composite cored wire bunch with package tape. The outer restrictive cheek is removed from the mandrel and the bunch is removed from mandrel by a unloading car.

The finished bunch of cored wire is tabled,packaged and sent to the finished product warehouse .
