  　　What is the sintering temperature range of the   electrode paste ? 　　The  electrode paste  height refers to the height from the upper end of the electrode clamp to the top of the  electrode paste . If the electrode paste is too high, the coarse and fine particles in the electrode paste are prone to delamination, or the electrode barrel is damaged due to the pressure of the paste column is too high. If the electrode paste column is too low, it is difficult to obtain a dense electrode due to the pressure of the paste column is too small and the filling property is poor. The electrode paste is consumed too quickly. The proper height of electrode paste column can improve the quality of electrode baking and reduce consumption. If the particle size is too large, the electrode paste suspension fault is easy to occur; If the particle size is too small, it is easy to cause paste spraying. 　　It is better to buy the finished electrode paste. If the material supplied by the manufacturer is qua

  　　With the continuous improvement of metallurgical technology, the application field of metallurgical products is expanding. At present, China’s basic industry is developing rapidly, especially the development of   electrode paste . 　　Electrode paste is a conductive material used for electric furnace equipment such as ferroalloy furnace and carbide furnace. It can withstand high temperature and has a small coefficient of thermal expansion. And has a relatively small resistance coefficient so that the loss of electric energy can be reduced. It has a small porosity so that the electrode in the heated state can be oxidized slowly. With high mechanical strength, the electrode will not be broken due to the influence of mechanical and electrical loads. 　　The current is input into the furnace through the electrode to generate an arc for smelting. The electrode plays a very important role in the whole electric furnace. Without it, the electric furnace cannot produce its role. To make the ele

It has a small porosity and can slow the oxidation of the heated electrode. With high mechanical strength, the electrode will not be broken due to the influence of mechanical and electrical loads. Electrode paste is an important consumable conductive material for the production of calcium carbide and ferroalloy. It is a “self baking electrode” in terms of its use properties. At present, each ton of ferrosilicon containing 75% Si produced by the mine thermoelectric furnace consumes about 45kg of  electrode paste , and each ton of calcium carbide consumes about 30kg of  electrode paste . The main raw materials for producing electrodes are anthracite, metallurgical coke and coal and coal

  　　Many customers know that   electrode paste   is a conductive material for ferroalloy furnace,   calcium carbide furnace   and other electric furnace equipment after using   electrode paste . However, the specific relationship between current electrodes is explained below: 　　The  electrode paste  has high temperature resistance and low thermal expansion coefficient. It has a relatively small resistance coefficient and can reduce the loss of electric energy. It has a small porosity and can slow the oxidation of the heated electrode. With high mechanical strength, the electrode will not be broken due to the influence of mechanical and electrical loads. 　　The current is input into the furnace through the electrode to generate an arc for smelting. The electrode plays a very important role in the whole electric furnace. Without it, the electric furnace cannot play a role. In order to make the electrode work normally under the temperature generated by the arc, it needs to have high oxidat

  　　A common problem in the production of ferronickel alloy by   submerged arc furnace   is that the self baking electrode is sintered slowly, and the electrode sintering speed is far lower than the electrode consumption speed, resulting in the working end of the electrode being too short. After tapping, the electrode can not reach the full load power supply even at the lower limit. In order to make the electrode reach the normal consumption speed, various manufacturers have developed different kinds of   electrode paste s to improve the sintering speed of the electrode, but they have not fundamentally solved the problem of under burning of the electrode, and also increased the production cost. 　　Some manufacturers changed the power supply system on the premise that the transformer power was unchanged, and correspondingly increased the secondary voltage. The current intensity was reduced by 20% ~ 40%, and the current density was reduced by 1 ~ 2 A / cm2. This is also the fundamental ca

  　　Submerged arc furnace is also called electric arc furnace or resistance electric furnace. It is mainly used for reducing smelting ore, carbonaceous reductant, solvent and other raw materials. It mainly produces ferrosilicon, ferromanganese, ferrochromium, ferrotungsten, silicon manganese alloy and other ferroalloys. It is an important industrial raw material in the metallurgical industry and chemical raw materials such as calcium carbide. Its working characteristics are that carbon or magnesium refractory materials are used as furnace lining and self-cultivation electrodes ( electrode paste  or sealed paste) are used. The electrode is inserted into the charge for submerged arc operation. It is an industrial electric furnace that uses the energy and current of the arc to pass through the charge and the energy generated by the resistance of the charge to smelt the metal. It is continuously fed and intermittently discharged with iron slag.
