Abstract
The utility model relates to an arc furnace current collection semi-ring and a conductive apparatus formed thereby, wherein the current semi-ring is provided with a cavity structure and equipped with a water inlet pipe and a water outlet pipe both communicated with the cavity. The arc furnace current collection semi-ring is characterized by directly casting a water cooling cavity thereon, thereby avoiding the defects that the prior imbedding annular steel pipe is used as a water cooling channel to cause a magnetic field effect and cause the total electrical efficiency of the entire apparatus to decrease, realizing the effective cooling of the current collection semi-ring, increasing the conductive capability and electrical efficiency of the current collection semi-ring, and prolonging the service life. Simultaneously, a water isolating rib sheet is arranged in the cavity of the current collection semi-ring, thereby lengthening the water flow path, reducing water flow blind corner, and playing an effect of increasing the mechanical strength of the current collection semi-ring; and the cavity structure of the current collection semi-ring can reduce the weight of the apparatus, material consumption and use cost, thereby having a great meaning for saving the more and more short copper material resource.
Description
Affiliated technical field
The utility model relates to a kind of mineral hot furnace auxiliary device, particularly relates to a kind of mineral hot furnace current collection semi-ring and reaches by its electric installation that consists of.
Background technology
The current collection semi-ring is the conductive component that is widely used on the mineral hot furnace, and the present position is connected in the backward stove with electric short net and powers on bell.At present used current collection semi-ring mostly is combined into the full circle ring by two semicircular ring and uses, and is subjected to the high-temperature furnace gas effect when equipment operation, and this cognition is ablated damage gradually, and conductive capability also can reduce.
Current collection semi-ring finished product adopts red copper to obtain by the method for casting, in order to improve conductive capability, increases the service life, and some adopts the method that passes into cooling water in inside to solve.Water-cooling channel then is that a castingin is at the circular steel pipe of collector ring inside, after importing electric current to the current collection semi-ring, the steel annulus can form magnetic field and waste electric energy, cause whole device power consumption efficiency to reduce, the drawback of aggravated simultaneously the heating of current collection semi-ring, striking sparks is even if the water flowing cooling also can't resolve root problem.Given this some current collection semi-ring is not just established cooling-water duct, has abandoned logical water-cooled measure.But will have a greatly reduced quality useful life.
Summary of the invention
The purpose of this utility model just is to overcome the defective of above-mentioned prior art, provides a kind of water flowing cooling Effective Raise electric conductivity, the mineral hot furnace current collection semi-ring that increases the service life.
Another purpose of the present utility model provides the electric installation that is made of above-mentioned mineral hot furnace current collection semi-ring.
For realizing that the technical scheme that above-mentioned utility model purpose is taked is:
A kind of mineral hot furnace current collection semi-ring is characterized in that described current collection semi-ring is cavity structure, and the water inlet pipe and the outlet pipe that communicate with this cavity are installed on it.
Be provided with the reinforcement sheet in the described current collection semi-ring cavity.
The electric installation that above-mentioned mineral hot furnace current collection semi-ring consists of, it is characterized in that: comprise left semi-ring, right semi-ring, conductive plate, connection conductive copper jaw plate watt seat, gland and conductive copper jaw plate, its left semi-ring, right semi-ring, conductive plate and connection conductive copper jaw plate are connected seat and are integrally formed structure, and the contact tube that arranges on the conductive copper jaw plate (being again water inlet pipe and water outlet pipe) cooperatively interacts by a watt seat, gland and is anchored on left semi-ring and the right semi-ring.
Described conductive plate is provided with some manholes, in order to be connected with electric short net with bolt.
The utility model current collection semi-ring is cavity structure, directly utilize this cavity structure as water-cooling channel, avoided in the prior art magnetic field effect of bringing as water cooling tube with circular steel pipe and drawback that the whole device electrical efficiency that causes descends, realized the cooling to the current collection semi-ring, thereby improved conductive capability and power consumption efficiency, prolonged useful life; The utility model arranges the confining tendon sheet in the current collection semi-ring simultaneously, both can lengthen flow path, reduces the current dead angle, again the current collection semi-ring has been played the effect that improves mechanical strength.The current collection semi-ring of cavity structure can alleviate the weight of this device, reduces and makes material, reduces use cost, is of great significance saving copper material resource tool day by day in short supply.
The utility model is installed watt seat with current collection semi-ring and conductive plate, copper jaw plate contact tube and is adopted an integral casting method cast solid, simple installation.
The utility model mineral hot furnace adopts copper material and the good non-ferrous metal manufacturing of conductive capability with the current collection semi-ring, has improved electric conductivity.
