Abstract

The utility model relates to a copper-iron compound energy saving conducting tile for a submerged arc furnace, and pertains to a main conducting part for an electrode holder of a submerged arc furnace. A conducting copper layer at the top of the conducting tile and a copper layer on the internal cambered surface of the tile form an L-shaped copper conducting layer, and the copper conducting layer constitute an integral double-metal energy-saving conducting tile in combination with a heat-resistant iron-base tile body. The copper layer on the internal cambered surface of the conducting tile is composed of a plurality of copper strips arranged in parallel, and the left and right sides of the internal cambered surface as well as the bottom of the conducting tile are made of iron-base materials. Therefore, the utility model has the advantages of a good conducting performance and low manufacturing cost, only about half of a full-copper tile, by changing the changing the traditional full-copper production method. The tile body of the conducting tile is made of heat-resistant iron-base alloy having a higher heat resistance than a full-copper conducting tile by 500 Celsius degrees, ensures that the tile body and the lower part of the conducting tile are not burned, and therefore has a long service life, and plays an active role in improving the production and reducing the comprehensive energy consumption. The conducting tile is broadly applicable to both a self-baked electrode, a carbon electrode and a graphite electrode.

Description

Ore deposit hot stove copper iron composite energy-saving Conductive holding element

1, technical field

The utility model belongs to electrodes in mine hot stove and controls device conduction critical piece (claiming conducting jaw plate again).

2, background technology

At present the Conductive holding element of existing traditional ore-smelting electric furnace is to adopt fine copper or copper alloy to make, and the shortcoming and defect part of this traditional product is:

1), copper cost height big with copper material quantity increased entreprise cost;

2) because of the fusing point of copper (1083 ℃) on the low side, in the hot stove high temperature in ore deposit uses, easily cause Conductive holding element bottom high heat burnout, cause under the Conductive holding element and partly shorten gradually, cause conductive area minimizing, furnace power to descend, production capacity also descends synchronously simultaneously, must often more renew brasses.

3) fusing point because of copper is low, when the brasses scaling loss badly shortens, often will watt in cooling water pipe burn out, cause leakage accident to take place, in a single day leakage accident takes place brasses just must more renew brasses by heating blowing-out, causes the increase of heating blowing-out number of times and time, has a strong impact on normal production, cause output, quality decline, raw materials for production waste, power mono-consumption to rise, thereby increase the production cost of enterprise.

4) because heating blowing-out work situation extreme difference when changing brasses, labour intensity are very big, be easy to generate the danger of personnel's burn.

5) because low loss rate, the reduction life cycle of accelerating brasses of the fusing point of copper increases entreprise cost.

3, summary of the invention

The purpose of this utility model is to avoid above-mentioned shortcoming and defect.Use full copper production to change the energy-conservation Conductive holding element of " 7 " font copper cambered surface into by tradition, can save and use copper quantity, can increase the service life again, the accident of having avoided Conductive holding element frequently to leak simultaneously, and reduced heating blowing-out number of times and the time that is used to change Conductive holding element, and reach stable furnace condition, improve the normal operation rate of electric furnace, good condition has been created in high and stable yields, brought into play the advantage of synthesis energy saving effect.

The purpose of this utility model realizes by following technological improvement:

The utility model changes the conventional conductive watt method that adopts full copper material to make, changing two kinds of metal unifications into makes, the framework that is the main body (ectosome) of Conductive holding element adopts the manufacturing of heatproof iron, the heat resistance of this Conductive holding element ectosome improves more than 500 ℃ than copper, guaranteed that thereby the Conductive holding element bottom is difficult for being burnt out having prolonged service life, avoided the generation of leakage accident simultaneously, ensure safety in production, key is to have reduced heating blowing-out number of times and time, improved electric furnace normal operation rate, highly beneficial condition has been created in stable furnace condition, stable and high yields.

The current-carrying part of the present utility model i.e. intrados of watt top and Conductive holding element adopts the pure copper material manufacturing, constitutes the copper conductive layer of 7 shapes, and with watt bluk recombination of heat-resisting iron-based be one.

The copper layer structure of the utility model Conductive holding element intrados is long strip type, and arranged by " river " shape and the inner arc copper face of the Conductive holding element formed by some copper bars, conducts electricity use as contact with electrode.

The utility model is a watt body and as the skin of Conductive holding element with heat-resisting iron-based, plays a part solar heat protection and protection copper layer.

With heat-resisting iron-based for a watt body, make conductive copper layer and the Conductive holding element be made up of with the Conductive holding element intrados of " river " shape some copper bars has the following advantages with fine copper " 7 " font:

1) adopting heat-resisting iron-based to make its heat resistance of Conductive holding element main body improves more than 500 ℃ than copper, can guarantee that its Conductive holding element bottom is difficult for being burnt out, having avoided the generation of Conductive holding element shortening and leakage accident, reduced the heating blowing-out number of times, improve electric furnace normal operation rate, is the energy-saving and cost-reducing advantageous conditions of having created.

2) adopting watt body of heat-resisting iron-based manufacturing because the fusing point height can increase the service life 1-3 times, is that enterprise saves a large amount of costs.

3) adopt heat-resisting iron-based to make watt body long service life and the frequent Conductive holding element of changing of minimizing, reduced labour intensity effectively, reduced the danger coefficient of producing.

4) this Conductive holding element is under the prerequisite that guarantees conductive area, and the copper conductive layer adopts the design of " 7 " type, can save copper material quantity about 60%, reduces the Conductive holding element cost in a large number, improves the business economic benefit.

5) this Conductive holding element has widely applicable advantage, not only can use (producing products such as ferroalloy, calcium carbide) on self-baking electrode, also can use (products such as manufacture silicon, yellow phosphorus, brown corundum) at carbon pole and graphite electrode.
