High-Quality 1.5kg Copper Rod 8mm Grounding Module Electrode
I. Introduction of copper bar
Copper bar is a solid copper bar that is extruded or drawn. There
are many kinds of copper rods, including purple copper rods, brass
rods, bronze rods and white copper rods. Different types of copper
bars have different forming processes and different
characteristics. Copper bar forming process includes extrusion,
rolling, continuous casting, stretching, etc.
Second, copper rod material classification
Copper bar materials include H59, H59-1, H59-2, H59-3, H60, H60-2,
H62, H63, H65, H68, H70, H80, H90; C1100, C1020, C2680, C2800,
C2600, C2801, C5191, C5210, C2200, C7521. C7541, C17200, C1070,
C7701, QSn6.5-0.1, QSn8-0.3, QSn4-0.3, BZn18-18, BZn15-20, CuBe2,
etc.
Third, the copper bar forming process
There are three copper bar forming process flows, as follows.
1, extrusion-(rolling)-drawing-(annealing)-finishing-finished
product.
2,Continuous casting (upward lead, horizontal or wheel, crawler,
dipping)-(rolling)-stretching-(annealing)-finishing-finished
product.
3,Continuous extrusion - stretching - (annealing) - finishing -
finished product.
IV. Copper bar forming process
Extrusion
1, the type of extrusion
(1) forward extrusion: refers to the extrusion of products in the
same direction as the direction of extrusion pressure extrusion
behavior.
(2) reverse extrusion: refers to the extrusion direction and the
direction of extrusion pressure opposite extrusion behavior.
(3) special extrusion: refers to other extrusion methods such as
hydrostatic extrusion.
2, the characteristics of extrusion
(1) the characteristics of forward extrusion: forward extrusion
equipment is relatively simple, the most widely used.
(2) the characteristics of reverse extrusion: reverse extrusion due
to reduce the friction between the billet and the extrusion barrel,
reduce the extrusion pressure, can improve the tool life, in the
small and medium-sized extrusion products are used more.
(3) the characteristics of special extrusion: special extrusion is
mostly used in the extrusion of special products.
Rolling
Copper bar rolling with hole rolling, spinning rolling and
planetary rolling three.
1, hole rolling: in the two-roller or three-roller mill, the
longitudinal rolling method for all types of profiles by the
rollers of the groove.
2, spinning rolling: through the spinning wheel on the rotation of
the metal plate or pre-formed blanks for the feeding motion and
spinning forming.
3, planetary rolling: in one or two support rolls and around the
support rolls around a number of planetary rolls on the mill
extrusion of various types of materials rolling method.
