With the modern development of iron and steel smelting technology, the safety and economy of the use of Graphite Electrodes and Electrode Nipples in steel mills have become increasingly prominent. So how to realize the ideal connection between the graphite electrode and connector? Based on its high precision, someone proposed a new concept of an … Read more
The salt-bath furnace is important heating equipment in the metal heat treatment process with simple structure, convenient use and maintenance, and low investment and maintenance costs. Sometimes, it can also be used in welding processes. The graphite electrode is the core component of the salt-bath furnace. In order to overcome the shortcomings of short electrode … Read more
Several major physical and chemical indicators are controlled within a certain range. It is not that the higher a certain indicator is, the better. In a certain sense, stability is more important than improvement. China’s rp graphite electrode industry-standard stipulates that the resistivity standard of 400~500mm in diameter is no more than 9 Ω·m for … Read more
Regarding the price of graphite electrodes, whether it is ordinary power products or high-power products, the increase in a certain period of time has exceeded 10%, and the average price can be doubled. Graphite electrodes are mainly made of petroleum coke and needle coke as raw materials, coal tar pitch as a binding agent, calcination, … Read more
The specific resistance of graphite electrode materials is very small. In order to obtain higher measurement accuracy, a stable current of several hundred amperes is generally required. This paper introduces the method of measuring the resistance and resistivity of the graphite electrode by using the ratio characteristic of the A/D converter. The efficient graphite electrode … Read more
Speaking of the use of graphite electrodes for sale, they are mainly used in electric furnace steelmaking. The graphite electrode for electric arc furnace smelting is an electric furnace steelmaking, and the graphite electrode is used to introduce current into the furnace. A strong current generates an arc discharge through the gas at the lower … Read more
