uhp 350 graphite electrode

Graphite high temperature anti-oxidation coating provides insulation protection for uhp 350 graphite electrode. uhp 350 graphite electrode is the key power element of electric arc furnace. It is used to conduct electric current and provide energy for furnace charge and molten steel refining. In terms of controlling the total cost of electric furnace steel, the cost of uhp 350 graphite electrode is one of the main considerations.

The loss of uhp 350 graphite electrode can be divided into continuous loss and discontinuous loss. Continuous loss mainly refers to the loss caused by oxidation, sublimation, corrosion, etc.; while the loss caused by damage, fracture and thermal shock peeling is a discontinuous loss.

The loss of uhp 350 graphite electrode can be divided into continuous loss and discontinuous loss. Continuous loss mainly refers to the loss caused by oxidation, sublimation, corrosion, etc.; while the loss caused by damage, fracture and thermal shock peeling is a discontinuous loss. Experts pointed out that the analysis of the loss mechanism of the uhp 350 graphite electrode shows that oxidation is one of the main reasons for the loss of the uhp 350 graphite electrode, accounting for more than half of the consumption of the uhp 350 graphite electrode.

Therefore, effective measures to prevent oxidation of uhp 350 graphite electrode can greatly reduce the consumption of uhp 350 graphite electrode and steelmaking costs. According to the oxidation theory of carbon materials, the oxidation reaction of uhp 350 graphite electrode can be divided into three different temperature regions. The second reaction temperature range is about 500-1000°C, which is called the low-temperature oxidation zone. The loss of uhp 350 graphite electrode only accounts for less than 2% of the total consumption.

The third reaction temperature range is above 1000°C, which is called high temperature oxidation zone. The high temperature oxidation loss is 20-50 times the low temperature oxidation loss. Therefore, in order to prevent the oxidation loss of uhp 350 graphite electrode, the high temperature oxidation zone should be studied.
