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.
