Issue 18/2015 - Large size carbon electrodes solve the problem of smelting pollution

Hebei Lianguan Electrode Co.
, Ltd.
has developed a high-performance carbon nano ultramicromaterial carbon electrode with a diameter of 1272mm, which fills the domestic gap of large-diameter new carbon electrode materials for large-scale mine heating furnaces, and solves
the problems of large-scale mine heating furnace smelting pollution.

The self-developed large-scale carbon electrode has excellent physical properties, and its bulk density, flexural strength and tensile strength are increased by 5%~10%
compared with the general carbon electrode.
The application of this product can solve the problems of breaking and cracking in the current large-scale mine furnace smelting process, improve the safety of the mine heating furnace and the oxidation resistance of the electrode, thereby eliminating environmental pollution and reducing the comprehensive use cost of smelting by more than
20%.
The technology has been authorized
by the national invention patent.

The company took the lead in developing a new carbon nano ultrafine material carbon electrode process in the international industry, which further improved the bulk density of the product and made its flexural strength reach 14PMa, which is 1 times higher than ordinary carbon electrode products; Through the development of the optimal raw material formula of carbon electrodes, the expansion coefficient of the product is reduced to less than
1/2 of ordinary carbon electrode products.
As a result, it not only enhances the antioxidant effect in the smelting process, avoids the phenomenon of furnace failure and "soft breaking" and "hard breaking" accidents in smelting, improves the working environment, saves operating costs, and greatly improves the quality of
smelting products.
At the same time, the low resistivity and high bulk density of carbon nano ultramicromaterial carbon electrode can reduce the ton cost of titanium slag smelting by nearly 400 yuan compared with similar products; The resistivity is 30% lower than that of ordinary carbon electrodes, which improves the furnace power and electric furnace efficiency, shortens the smelting time, and the effect of power saving is obvious, and the smelting of 1 ton of ferroalloy can save 15%~20%
of electricity compared with ordinary carbon electrodes.

With the support and encouragement of the national industrial transformation and upgrading policy, the demand for large-scale electrodes will grow rapidly, and it is expected that the annual demand for domestic carbon electrodes will reach 250,000 tons by 2020
.
At present, Hebei Lianguan Electrode Co.
, Ltd.
has invested more than 30 million yuan to build a professional production line
for carbon nano ultramicromaterials carbon electrodes.
