Matters need attention in Steel liquid Smelting
Electric adjustment since the start current and power, and with electric furnace charging must be consistent, should be paid attention to in the process of smelting furnace bottom material, carefully watch the electric furnace in the steel under the change and degree of smelting furnace charge, can't have the phenomenon that burden not going out , molten steel during basic full furnace smelting to stop feeding, clear away the impurity in the furnace slag, the thermometer were used to detect steel up to 1200 degrees extraction assay in the furnace, and then continue to smelting furnace. After waiting for test results came out, according to the test results to the chemical composition of molten steel in the furnace burden.
you should remove all the clutter in the furnace before burdening , molten steel up to 1500 degrees of the required materials to join in the furnace, waiting for the ingredients dissolved after the extraction liquid steel steel stir assay, watch the measuring temperature of molten steel in the furnace, measure every 2 minutes at a time, until the liquid steel up to 1600 degrees keep three minutes boiling, verify the second test result for steel, if there are any differential then adjust again, pour to slag ladle stir, pouring temperature between 1520-1550.
during the period of repairing Furnace workers must match lining material by standard,burden to match all, mix well, dry humidity is appropriate, a furnace to give priority to with hardness and uniformity, reach the furnace interior surface is smooth.
Note: high temperature melting, slag and steel mixing evenly, ow temperature pouring.
