REFINING METHOD FOR CAST IRON AND REFINING FURNACE USED THEREFOR
Document Type and Number:
Japanese Patent JP2016199774
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for refining cast iron requiring no demanganization agents such as sulfide and slag-making material or combustible gas and having reduced generation slag, capable of swiftly and efficiently removing manganese from raw material for cast iron having a manganese content and feeding the molten metal of the cast iron having a required content of manganese or the like, and a refining furnace used therefor.SOLUTION: Provided is a refining furnace for cast iron comprising: a furnace body 10 receiving the molten metal of cast iron; rotary means 20 of rotating the furnace body 10 to a refining operation position; oxygen feeding means 14 of feeding oxygen to the upper face of the molten metal of the cast iron received in the furnace body 10; and air feeding means 17 having an air feed tube 18 provided therein so as to be opened in the furnace body 10 in a manner to be inclined downward to the furnace body shaft from the side face of the furnace body, the air feed tube feeding air into the molten metal of the cast iron received in the furnace body 10.SELECTED DRAWING: Figure 2
