Quality standard:
The traditional indexes such as ash, volatile matter, resistivity, compression strength, volume density and so on are concerned about the performance and quality of electrode paste.
With the frequent occurrence of "soft break" and "hard break" quality accidents in recent years, coupled with the requirement of environmental protection, the regulation and control policy of backward production capacity and the rapid development of large closed mine thermal furnace, Some calcium carbide and ferroalloy production enterprises are not limited to the requirements of the quality of electrode paste. Some enterprise technical experts and scholars combined with some foreign enterprise electrode paste quality standards, some other key technologies such as plasticity, fluidity, softening degree, thermal shock resistance and other performance indicators were discussed and evaluated.
In April 2015, China began to implement a new industry standard for self-baking electrode paste for mine thermal furnaces . The establishment of the new standard is conducive to promoting the continuous progress of China's electrode paste industry, but also conducive to the production of their own different furnace conditions, select suitable electrode paste. However, we should also see that compared with foreign countries, China is still less than the standard items of electrode paste detection, which can’t fully reflect the use performance of the electrode paste, international competitiveness is not strong enough.
