    Abstract: PURPOSE: A method and apparatus for refining molten steel in a converter using residue slag are provided to improve material property of residue slag in order to increase the measurement rate of quicklime. CONSTITUTION: A method for refining molten steel in a converter using residue slag comprises a loading step, a refining step, a step of putting out steel, a fore blow step, and a coating step. Molten iron(20) is inserted into a converter(10) at the loading step. Oxygen flows into the converter to remove foreign matters at the refining step. The refined molten steel moves to a ladle(27). Residue slag reacts with oxygen by positioning an oxygen supply lens in a converter after the step of putting out steel. In the coating step, the residue slag is coated on the inner wall of the converter after the fore blow step.

    Abstract: A method for manufacturing molten steel containing low-phosphorus using finex hot metal is provided to use decarbonization slag as a material instead of quicklime in order to protect a furnace and reduce manufacturing cost by reducing the amount of quicklime to be used as a material. A method for manufacturing molten steel containing low-phosphorus using finex hot metal comprises the following steps. Fine iron ore is reduced using fluidized reduction furnaces(3,4,5) and inputted into a melting furnace to manafacture a hot metal. A furnace is coated with decarbonization slag. Finex hot metal and scrap iron are inputted into the furnace. The finex hot metal is smelted. The smelted finex hot metal is pulled out. The basicity of decarbonization slag is from 6.5 to 7.5.

    Abstract: An extra-low-carbon steel refining method at a converter is provided to maintain constant basicity with reducing the amount of injected supplementary raw material like quicklime. An extra-low-carbon steel refining method at a converter comprises: a step for remaining the slug of 4~10wt% of ingot steel after completing tapping at the converter; a step for coating remained slug at the converter; a step for injecting oxidation iron(FeO) to the converter; a step for charging scrap iron and hot metal to the converter and performing dephosphorization blowing; a step for putting the slug formed through fourth step into the slug port; and a step for performing decarbonization refinement. The step for performing decarbonization refinement comprises a step for injecting siO2 having the weight of 4:1 rate to the calculated quicklime weight with quicklime.

    Abstract: A melting furnace with easily removable refractories is provided to remove the refractories from the melting furnace easily and restrain dust from being generated on a workplace accordingly by forming a separating element between a coil cement and refractories in the melting furnace, thereby preventing reciprocal adhesion of the coil cement and the refractories. A melting furnace(100) with easily removable refractories comprises: a melting furnace metal case(110) of which an upper part is opened, and which is formed in the form of a vessel; a coil cement(120) adhered to an inner surface of the melting furnace metal case; refractories(130) formed on an inner side of the coil cement; and a separating element(140) formed between the coil cement and the refractories to prevent the coil cement and the refractories from being adhered to each other, wherein the separating element includes a rock wool fiber. The melting furnace with easily removable refractories further comprises: a gate(160) opening or closing a through hole formed in the bottom of the melting furnace metal case; and a plate(150) formed on an inner bottom face of the melting furnace metal case to open or close the through hole.
