carbon electrode paste
CGM Carbon tells you two major issues that have to be paid attention to in the purchase of carbon electrode paste aggregates and electric calcined coal
Electric calcined coal as the aggregate of carbon electrode paste airtight paste directly affects the quality of the electrode paste airtight paste. Therefore, the quality control of electric calcined coal is very important in the production of carbon electrode paste airtight paste.
So, what misunderstandings should the carbon electrode paste factory avoid when purchasing electric calcined coal?
1. Electrically calcined coal parameters only look at resistivity. Many carbon electrode paste factories blindly pursue resistivity when purchasing. What they don’t know is that the lower the resistance, the better the quality of the calcined coal. Generally speaking, the longer the anthracite is calcined in the electric calciner, the lower the resistivity. However, the longer the time, the lower the strength of the electric calcined coal. The strength and electrical resistance of electric calcined coal are inversely proportional. If the strength of the electrically-calcined coal as the aggregate of carbon electrode paste is too low, it will not play a supporting role in the manufacture of carbon electrode paste. Generally speaking, electric calcined coal with a resistance of 450-500 is sufficient.
2. As long as the parameters are qualified, the origin of electric calcined coal does not matter. It can be said that there is still a big gap between Shanxi electric calcined coal and Ningxia electric calcined coal in the application of carbon electrode paste products under the same resistance state. Ningxia Taixi anthracite is world-famous because of its low volatility and low ash content. For example, Shanxi anthracite has an ash content of about 11, and Ningxia’s electric-calcined coal can achieve 5, Shanxi’s anthracite has a volatile content of about 20, and Ningxia Taixi’s anthracite can reach about 11. Therefore, for carbon electrode paste manufacturers, Ningxia Taixi Power Calcined Coal is the first choice.
Of course, the price of electric calcined coal in some areas is higher, and the distance is longer, and the freight is also higher (the freight has now risen to 330 on the basis of 220 per ton). However, for manufacturers pursuing reputation and quality, high-quality original purchase guarantee is a must.
