Qualified raw materials from the raw material yard, such as manganese ore, silica, coke, auxiliary materials, etc., are weighed proportionally by the weighbridge, and then loaded on the trolleys manually, and the carts are transported to the second floor by the elevator, and each batch is poured into the floor for manual mixing. Each batch is poured into the floor and mixed manually. The materials are added into the furnace manually.
According to the iron output system formulated by the smelting technology, after the specified smelting time, the operator in front of the furnace operates the burner to open the furnace eye and release the iron and liquid slag from the furnace eye.
The molten iron and liquid slag are mixed out, and the molten iron and slag are separated by castor and slag, and the molten iron flows into one side of the sand pit, and the slag flows into the other side of the sand pit, and are cleaned up separately after cooling.
Finally, it is weighed and packaged into storage, and according to the lab sheet, it is stacked according to the composition.
The smoke and dust enter into the dust exhaust flue through the smoking hood on the furnace mouth, and the bag-type dust catcher is arranged outside the plant, and the smoke and dust out of the furnace are cooled down by the cooler and enter into the dust catcher, and the concentration of smoke and dust discharged after treatment reaches the emission standard of the state.
The circulating cooling water is supplied by the circulating water pumping station. After entering the electric furnace, the cooling water naturally flows back to the cooling pool by using the drop difference, and then it is naturally cooled in the pool and supplied to the front of the furnace by the water pump.
