Characteristics:
The electrode holder is usually called a chuck or chuck. It has two basic functions: mechanically clamp the electrode, and release a section of the electrode after the electrode is consumed; the other function is to conduct current to the electrode. Most chucks are copper castings.
The products made by the process of vacuum casting, forging and heat treatment have compact grain and high-density organization without any defect.
The material of Cu-Cr-Zr has higher physical mechanical properties than that of traditional chromium bronze.
The eleltrode holders are made by vacuum casting directly or cast with copper pipe for water passage.
Specifically refers to an electrode holder for electric arc furnaces. BACKGROUND An electric arc furnace is a widely used industrial electric furnace, and a ladle refining furnace as one of the main equipment in the steelmaking industry is one of them. The electrode holder of an electric arc furnace is usually made of pure copper, which can effectively block eddy currents, reduce energy consumption and heat generation. The electrode chuck is made of copper alloy and has good electrical conductivity. Compared with the traditional electrode chuck, the copper chuck has a longer service life.
