Description
Technical field
The utility model relates to the tundish upper nozzle that steel-making enterprise uses, and is that a kind of tundish combined type lengthens filling pipe end.
Background technology
The structure of existing composite upper runner generally adopts three parts to form, that is: parent, zirconium core and zirconium bowl are adhesively fixed by tack coat between each parts.The deficiency of the composite upper runner of this structure is: because filling pipe end in use directly contacts with molten steel, binding agent is soluble under the high temperature of molten steel, thereby make the bond sites of each parts easily produce the bleed-out phenomenon, therefore, this mouth of a river normal operation life-span is about 12 hours, this brings larger waste to enterprise, and makes production cost high; Simultaneously, because the structure of this filling pipe end needs three parts to form, so manufacturing process is complicated, manufacturing cost is high, and the qualification rate of product is low etc.
The utility model content
The purpose of this utility model is, provides a kind of combined type to lengthen filling pipe end, makes its solve the deficiencies in the prior art, thereby improves service life, cuts the waste.
The utility model for achieving the above object, be achieved through the following technical solutions: combined type lengthens filling pipe end, comprise aluminium carbonaceous parent, aluminium carbonaceous parent outer shape is the annular closed shape that curved surface consists of, aluminium carbonaceous parent is offered inner chamber, the inner chamber of aluminium carbonaceous parent is installed the high temperature resistant core body of zirconium carbonaceous, the zirconium carbonaceous is high temperature resistant, and through hole is offered in the core body centre, the thickness of the zirconium carbonaceous is high temperature resistant core body top H1 is greater than the thickness of the middle and lower part H2 of the high temperature resistant core body of zirconium carbonaceous, the middle and lower part H2 of the high temperature resistant core body of zirconium carbonaceous is cylinder, the inwall of aluminium carbonaceous parent inner chamber and the outer wall close contact of the high temperature resistant core body of zirconium carbonaceous, the upper surface of the upper part aluminium coating carbonaceous parent of the high temperature resistant core body of zirconium carbonaceous, the zirconium carbonaceous is high temperature resistant core body upper end is planar annular body L1 away from the position of through hole center line, the cylinder upper part that planar annular body L1 the inner extends downward the high temperature resistant core body of zirconium carbonaceous middle and lower part H2 is cone L2, and outer wall and the aluminium carbonaceous parent internal chamber wall connecting portion of the zirconium carbonaceous is high temperature resistant core body top H1 are step-like.The height of the top H1 of the high temperature resistant core body of zirconium carbonaceous is the 1/5-1/3 of the high temperature resistant core body total height of zirconium carbonaceous.The thickness of the middle and lower part H2 of the high temperature resistant core body of zirconium carbonaceous is the 6-15 millimeter.Stepped hole is offered in the bottom of aluminium carbonaceous parent and the high temperature resistant core body of zirconium carbonaceous.Aluminium carbonaceous parent outer shape is cone.The outer shape top of aluminium carbonaceous parent is that cone, bottom are cylinders.
The utility model has the advantage of: combined type is added long nozzle adopt aluminium carbonaceous parent and two parts of the high temperature resistant core body of zirconium carbonaceous to form, removed tack coat, and the parts of zirconium bowl have been removed, make two parts adopt the connected mode of close contact to connect in the junction, production cost is significantly reduced, simultaneously, increased substantially service life, make the life-span of service life of filling pipe end and material itself suitable, and production technology is simplified, improved production efficiency and product percent of pass etc.
