Description
Technical field
The utility model relates to the circuit connecting unit of electric arc furnaces water power cable, particularly a kind of copper bar for electric arc furnaces.
Background technology
Electric arc furnaces is the electric furnace of high melt ore and the metal utilizing electrode arc to produce.During gas discharge formation electric arc, energy is very concentrated, and arc district temperature is more than 3000 DEG C.For smelting metal, electric arc furnaces is larger than other converter technological flexibilities, and effectively can remove the impurity such as desulfuration, phosphorus, furnace temperature easily controls, and occupation area of equipment is little, is suitable for the melting of superior alloy steel.
Electric arc furnaces belongs to powerful device, therefore connects in order to safety often adopts the copper bar that can bear significant power demand at circuit.All in use can there is heat condition in various degree in traditional copper bar.When copper bar is under continuous high temperature operation, its service life and use safety be all its will faced by problem.
