Abstract
The utility model relates to an air permeable brick for a medium frequency induction furnace. The utility model is provided with an air permeable brick protective layer, wherein a conical bore with an opening on the top end is arranged in the air permeable brick protective layer. A truncated conical air permeable brick core matched with the conical bore is arranged in the conical bore, a flute is arranged at the bottom of the air permeable brick core, a sealed ceramic end cover is arranged under the flute, and a gas supply pipe extending outside the air permeable brick protective layer is arranged in a central hole in the center of the ceramic end cover. Therefore, the sealing property of the gas chamber is reliable, and the influence on argon refinement in the furnace by the electric induction is avoided.
Description
Technical field
The utility model relates to the air brick that a kind of intermediate frequency furnace is used.
Background technology
At present, each intermediate frequency furnace is smelted high-grade alloy steel, stainless steel, ultralow charcoal steel etc. and is all existed molten steel purity and alloy composition to be difficult to reach specification requirement, and its key is an ar blowing refining in the stove.But, on intermediate frequency furnace,, the conduction of metal shell structure is subjected to electric induction owing to making the air brick in the furnace bottom, and the metal shell oxidation is rubescent, and oxidized iron sheet comes off, and causes metal shell to snap, thereby, be difficult to guarantee the specification requirement of institute's steelmaking kind.
Summary of the invention
The purpose of this utility model provides the air brick that a kind of intermediate frequency furnace is used, it is the sealed air chamber of groove formation with ceramic end cap and air brick brick core bottom, also can not make the air brick in the furnace bottom be subjected to electric induction, utilize the argon gas that is pressed into this air chamber directly intermediate frequency furnace to be carried out ar blowing refining in the stove.
The purpose of this utility model is to adopt following structure to realize: the air brick that a kind of intermediate frequency furnace is used; has an air brick protective layer; and offer the conical bore of top end opening in it; in this conical bore, be provided with the air brick brick core of a truncated cones that matches again; offer a groove in the bottom of this air brick brick core; and the ceramic end cap of a sealing is set below this groove, in the centre bore at this pottery end cap center, wear an appendix that stretches out outside the air brick protective layer again.
The groove lower end of described air brick brick core is provided with internal thread, and described ceramic end cap is cylindrical flat board, and is provided with the external screw thread that matches with the groove internal thread of air brick brick core on cylindrical outer rim.
Described ceramic end cap is the spill disk, and the outward flange inboard is provided with the internal conical surface that matches with the recessed poppet surface of air brick brick core.
Described ceramic end cap is cylindrical flat board, and with the Qi Ding plane against the groove floor of air brick brick core and bonding with viscose.
The utility model can make the air chamber sealing property reliable, can avoid the influence of electric induction to ar blowing refining in the stove again.
