Abstract
The utility model discloses a direct current is bottom electrode for ore smelting electric arc furnace. Electrode package draws together at this end: vane type electrode (1), electrically conductive bottom plate (2), current conducting plate (3), insulating layer (5), copper bar (6), electric heater stove bottom (7), vane type electrode (1) welding be in electrically conductive bottom plate (2) on, current conducting plate (3) with electrically conductive bottom plate (2) the welding, current conducting plate (3) with copper bar (6) connect, insulating layer (5) set up to be in electrically conductive bottom plate (2) with electric heater stove bottom (7) between. Adopt the utility model discloses a direct current is bottom electrode for ore smelting electric arc furnace can be so that end electrode assembly's simple structure, water tank in order to avoid connecing contact heating, makes the radiating effect show more.
Description
Technical field
Originally it is related to DC-ore-heating field of electric fires, more particularly to a kind of DC-ore-heating electric furnace hearth electrode.
Background technology
At present, in the wide variety of modern direct current furnace of metallurgical industry it is a new technology growing up the beginning of the seventies.
China's ferroalloy production uses always ac electric arc furnace, and major defect is that power factor is low, and power consumption is high, and electric arc is unstable, and noise is big.
The hearth electrode of DC-ore-heating electric furnace mainly has three kinds of many air cooled bottom electrodes, single water-cooled hearth electrode and monolithic conductive hearth electrode
Type, the complex structure of three types, cost is high.
Utility model content
The purpose of this utility model is to provide that a kind of simple structure, low cost, electric conductivity be good, heat dispersion is good
DC-ore-heating furnace hearth electrode.
For achieving the above object, this provides following scheme：A kind of DC-ore-heating electric furnace hearth electrode, it is characterised in that：
Including paddle electrode, conductive soleplate, insulating barrier, conductive plate, water cooling box, copper bar, electrothermal furnace furnace bottom composition.
Wherein, described paddle electrode is welded on described conductive soleplate, described conductive plate and described conduction
Base plate is welded, and described conductive plate is connected with described copper bar, and described water cooling box is welded with described conductive soleplate, described
Water cooling box is cooled down to described conductive plate with described copper bar, and described insulating barrier is arranged on described conductive soleplate and institute
Between the electrothermal furnace furnace bottom stated.
Wherein, the combined closure system of described copper bar is 0.1A/mm2。
According to the specific embodiment that the utility model is provided, the utility model discloses following technique effect：By blade
On conductive soleplate, conductive plate and conductive soleplate are welded formula electrode welding, and conductive plate is connected with copper bar, water cooling box and conductive soleplate
Welding is cooled down to conductive plate with copper bar.Paddle electrode is adopted in the application, with common mode contrast, conducting surface is increased
Product, rapid heat dissipation, electrical efficiency is higher than adopting the direct heating efficiency of graphite in the past, higher to the utilization rate of electric energy；Using insulation
Layer can make conductive soleplate with whole furnace bottom bottom insulation；Using water cooling box, contact point is not allowed to generate heat, radiating effect more shows
Write.
