Tin dioxide (sno2) electrodes is widely applied to the smelt of top-grade optical glasses and electrolytic aluminum trades. Because it cant make the glass polluted, it is especially applied to the smelt of flint glass, barium flint and barium crown and so on. This achievement has already appraised by the expert of henan province science & technology agency. The whole prosperities lie in the leading position in domestic and main prosperities are up to the international advanced level.

Laxmi Power Solutions Product Description: Lps Gi 76 Mm Dia Pipe Type Earthing System
This advance Pipe in Pipe maintenance free earthing system is supplied in two folds:-
1. The Earth Electrode has pipe in pipe technology concept that involves two low carbon mild steel pipes one inserted inside the other. Both the pipes are subjected to anti rust coating of 100 microns. The pipes are of Indian Specification 1239 medium class as prescribed by earthing manual of Indian Standard 3043. The empty space inside the electrode is filled with high conductive crystalline mixture specially formulated and developed to create a minimum resistive path within the electrode.
2. Ground improving material is a back fill compound that is mixed in the soil around the earth electrode within the sphere of influence of the electrode to increase the effectiveness of the earthing system. The compound being hydroscopic in nature therefore it maintains the moisture level continuously during seasonal imbalances. The compound is also very conductive hence eliminates the use of salt and charcoal and maintains the conductive nature of soil and the compound is also very swelling in nature thus it eliminates air pockets in the soil and increases the contact area with the electrode.

Graphite electrodes are mainly made of petroleum coke and needle coke as raw materials and coal tar pitch as binder. They are made by crushing and screening ,kneading, forming,baking ,impregnation graphitization and machining. They are released in the form of electric arcs in an electric arc furnaceï¼?then heating and melting the raw materials as electrode.GE can be classified into RP, HP and UHP according to different specification. The products have the advantages of low resistivity, low ash content, uniform structure, good thermal vibration resistance, high mechanical strength, low thermal expansion coefficient, precise fit of electrode and nipple, etc, which is an excellent materials for electric steel-making and ore smelting.
ï??Application:
1. Used in electric arc steel making furnaces: Graphite electrodes are mainly used for electric furnace steel -making. Electric furnace steel-making uses graphite electrodes to introduce current into the furnace, and a strong current passes through the gas at the lower end of the electrode to generate arc discharge, which is caused by the use of electric isolation heat for smelting.
2. Used in submerged electric furnace: graphite electrode submerged heating furnace is mainly used to produce ferroalloy, pure silicon, yellow phosphorus, matte and calcium carbide.
3. For resistance furnaces: graphitization furnaces for the production of graphite products, furnaces for melting glass and electric furnaces for the production of silicon carbide are all resistance furnaces. The raw materials in the furnaces are not only heating resistors, but also heated The goal.
4. For processing: Many graphite electrode blanks are also used for production and processing into various products such as crucibles, graphite boats, hot die casting molds and vacuum furnace heaters.
