Abstract
The utility model relates to a ceramic stopper-rod for steel ladle, in particular to a two-section type ceramic stopper-rod for steel ladle. The defect of short service life of the existing ceramic stopper-rod is solved. The two-section type ceramic stopper-rod for steel ladle is composed of a core rod, a refractory brick, and a plug. The two-section type ceramic stopper-rod for steel ladle is characterized in that the core rod is composed of a main core rod and a head core rod. The refractory brick is sheathed on the main core rod. The plug is fixed on the head core rod. During operation, if the high temperature molten steel penetrates to the plug and the head core rod is burned, but the main core rod is still intact, only replacing the damaged head core rod with a new head core rod can recover the work of the ceramic stopper-rod. The utility model has simple structure. The scrap amount of the ceramic stopper-rod is reduced greatly, and the cost is saved.
Description
One, technical field
The utility model relates to a kind of steel ladle pottery stopper rod, particularly a kind of two-segment type steel ladle pottery stopper rod.
Two, background technology
Referring to Fig. 1, Fig. 2, steel ladle 1 is the casting equipment of steel-making of intermediate frequency furnace, and pottery stopper rod 2 seals the cast gate 3 of steel ladle 1 bottom when steel ladle 1 is accepted molten steel, opens cast gate 3 when casting, emits molten steel.Pottery stopper rod 2 is made up of parts such as plug 4, refractory brick 5, chock plugs 6, and refractory brick 5 is enclosed within on the plug 4 during work, and chock plug 6 is fixed on the end of plug 4.The space of chock plug 6 heads is filled up with fire clay during work, and fire clay often peels off in the actual casting cycle, and high-temperature molten steel creeps into the space of chock plug 6 heads, burns out the head of plug 4, thereby causes scrapping of whole pottery stopper rod 2.The consumption of pottery stopper rod 2 is very big in the actual production process, and waste is serious.
Three, summary of the invention
The purpose of this utility model provides a kind of two-segment type steel ladle pottery stopper rod, and it is big to solve pottery stopper rod consumption, the cost technical problems of high.A kind of two-segment type steel ladle pottery stopper rod comprises plug, refractory brick, chock plug, it is characterized in that plug is made up of a main plug and a plug, and a main plug and a plug are by being threaded togather, and refractory brick is enclosed within on the main plug, and chock plug is fixed on the plug.If high-temperature molten steel creeps into chock plug and burns out the head of screw plug during work, a just plug of scrapping, and main plug is still intact, only needs to change a plug pottery stopper rod is resumed work.
The utility model is simple in structure, reduces the learies of pottery stopper rod in a large number, saves the equipment use cost, remarkable in economical benefits.

Fig. 3 is the utility model structure diagram
4-plug, 5-refractory brick, 6-chock plug, 7-master's plug, a 8-plug, 9-screw, 10-pad.
Five, the specific embodiment
Referring to Fig. 3, a kind of two-segment type steel ladle pottery stopper rod, form by parts such as plug 4, refractory brick 5, chock plugs 6, plug 4 is made up of a main plug 7 and a plug 8, a main plug 7 and a plug 8 are by being threaded togather, refractory brick 5 is enclosed within on the main plug 7, and chock plug 6 usefulness screws 9 and pad 10 are fixed on the plug 8.If high-temperature molten steel creeps into chock plug 6 and burns out head of screw plug 8 during work, a just plug 8 of scrapping, and main plug 7 is still intact, only needs to change a plug 8 the pottery stopper rod is resumed work.
The utility model is simple in structure, reduces the learies of pottery stopper rod in a large number, saves the equipment use cost, remarkable in economical benefits.
