Detailed description of the invention
Below against by the description to optimum embodiment, the detailed description of the invention of the present invention is made the most in detail
Thin explanation.
The manufacture method of this surface high connductivity heat zinc coating plate, including following operation: surface cleaning by degreasing---annealing
Stove continuous annealing-------finishing straightening----surface coated treatment that enters zinc pot galvanizing by dipping；Wherein, finishing is drawn
Rectifying in operation, polishing machine working roll is operated under capacitive and carries out hacking, and working roll roll surface roughness controls
In 2.0-2.5 μm, heat zinc coating plate surface roughness is 2.0-2.5 μm.The surface of surface high conductivity heat zinc coating plate
Roughness and peak value thereof control to be one of this production difficult point, in conjunction with finishing prebasal plate surface roughness, light
Complete machine working roll capacitive hacking, controls roller footpath Φ 450mm working roll roll surface roughness in 2.0-2.5 μm
Scope, it is achieved heat zinc coating plate surface low roughness, peak value texturing.Another use mass percent is 2.0%-2.5%
Finishing liquid lubrication polishing machine, strip steel, by the polishing machine through lubrication, can ensure that plate shape is smooth and surface cleaning,
It is further ensured that the finishing effect realizing galvanizing product low roughness, peak value.
The manufacture method of this surface high connductivity heat zinc coating plate, by controlling, to plating surface roughness and peak value
Zinc product surface quality is controlled, and the heat zinc coating plate of production has extremely low resistance, surface has high conductivity.
Meanwhile, surface coated treatment operation, the film of galvanized sheet face coat heavily controls at 1.1g/m2, galvanized sheet
Face coat double interfacial film weight deviation is ± 0.1g/m2.Zinc-plated rear galvanized sheet surface carries out processing roller coating technology, table
The film weight of finishing coat and the control of uniformity are the two of this production difficult points, comprehensive strip steel surface roughness,
Application roll surface roughness, speed and pressure match between feeding roller and application roll, between application roll and strip steel
The influence factor such as pressure, control coated film and focus on 1.1g/m2, galvanized sheet face coat double interfacial film weight deviation
For ± 0.1g/m2, two-sided 6 are detected and control film weight deviation at ± 0.1g/m2, it is ensured that whole plate facial film weight average
Even；Realizing the control effect that film coincidence is fitted, had good uniformity, belt steel surface has excellent electric conductivity,
Surface is not turned on rate less than 3%.
The manufacture method of this surface high connductivity heat zinc coating plate, by heavily controlling the film of galvanized sheet face coat
System, accurately to control the uniformity of galvanized sheet face coat, to reduce heat zinc coating plate sheet resistance, improves heat
Galvanized sheet surface conductivity.
Further, two-sided 6 the middle edge of galvanized sheet face coat 2 from galvanized sheet edge distance are
2.5cm, two-sided six dot spacings are from equal.Six point selection on two-sided: in 6,2 is edge two point, and
Other 4 are equally spaced.The selection of 6 middle edge 2 is the most crucial, owing to edge is in working roll roll-in
Under effect, edge coating uniformity is difficult to control；Steel band width is generally 1.3-1.5 rice, select edge 2 from
Galvanized sheet edge distance is 2.5cm, and edge is consistent with centre position coating uniformity, can be to whole galvanized sheet
Face coat uniformity is controlled, and to reduce heat zinc coating plate sheet resistance, improves heat zinc coating plate surface conductance
Property.

Base plate surface roughness Ra:1.0 μm, peak value RPc (/cm): 115, coated film weight 1.1g/m2, surface
Resistance 0.024m Ω, the rate of being not turned on is 0%.
Embodiment 2: surface conductivity is affected by coated film weight and uniformity.
Base plate surface roughness Ra:1.0 μm, peak value RPc (/cm): 90, coated film weight 1.1g/m2, surface
Resistance 0.040m Ω, the rate of being not turned on is 0%.
Base plate surface roughness Ra:1.0 μm, peak value RPc (/cm): 90, coated film weight 1.3g/m2, surface electricity
Resistance 0.052m Ω, the rate of being not turned on is 50%.
Base plate surface roughness Ra:1.0 μm, peak value RPc (/cm): 90, coated film weight 1.45g/m2, surface
Resistance 0.058m Ω, the rate of being not turned on is 80%.
Verifying through above example, galvanized sheet surface roughness controls at 2.0～2.5 μm, the film of face coat
Heavily control at 1.1g/m2Time, the sheet resistance value of the electric heating galvanized sheet of the manufacture method manufacture of heat zinc coating plate is less than
0.2M Ω, it is 0 that surface is not turned on rate.
Obviously the present invention implements and is not subject to the restrictions described above, as long as have employed the method structure of the present invention
Think the improvement of the various unsubstantialities carried out with technical scheme, all within protection scope of the present invention.
