Structural Features Of SR Submerged Arc Furnace
The SAF is an industrial electric furnace with huge power consumption.
Its mainly composed of furnace shell, furnace cover, furnace lining, short net, water cooling system, smoke exhaust system, dust removal system, electrode shell, electrode pressing and lifting system, loading and unloading system, gripper, burn-through device, hydraulic system, submerged arc furnace transformer and various electrical equipment.
SAF Working Characteristics
70% of the system reactance of the submerged arc furnace is generated by the short-circuit system, and the short-circuit is a system with a large current, and the maximum current can reach tens of thousands of amperes. Therefore, the performance of the short-circuit determines the performance of the submerged arc furnace. It is for this reason that the natural power factor of the submerged arc furnace is difficult to reach above 0.85.
The natural power factor of most furnaces is between 0.7 and 0.8. The low power factor not only reduces the efficiency of the transformer and consumes a lot of useless work, but also imposes additional power fines on the power department. At the same time, due to the manual control of the electrode and the stacking process, the power imbalance between the three phases increases, and the maximum imbalance can reach more than 20%, which leads to low smelting efficiency and increased electricity bills.
Therefore, improving the power factor of the short-circuit and reducing the imbalance of the power grid have become effective means to reduce energy consumption and improve smelting efficiency.
If appropriate measures are taken to improve the power factor of the short-circuit, the following effects can be achieved:
(1) Reduce power consumption by 5~20%;
(2) Increase production by more than 5%~10%
