Background technology
The ratio in the current China of continuous casting of iron and steel is up to 98% or more, and other than extremely individual steel grades, general steel grade is all to pass through company
Continuous casting converts molten steel to steel billet.But for some high-performance steel grades（Car panel, high-pressure oil gas pipeline super-purity ferrite
Stainless steel etc.）, production process in addition to make steel and external refining in terms of to do a large amount of work other than, with steel contacts
All refractory materials are intended to walk towards the direction of high-level material.In terms of refractory brick, middle packet refractory material for working layer, people are
It makes an adjustment, the long nozzle for connecting ladle and tundish is the important ring that in addition to this another prevents secondary oxidation of steel
Section.Each ladle needs to clear up sundries outside collector nozzle of ladle after having poured molten steel, while needing to clear up in long nozzle the rim of a bowl
Wall, the long nozzle generally used are that the pipeline oxygen with pressure is usually used in scale removal process with common alumina-carbon material
Gas is cleared up, it is easy to cause the oxidation of the rim of a bowl inner-wall material in scale removal process and irregular erosion is caused to peel off, and pass through
Several pour time is got off, and the rim of a bowl inner wall can be caused rugged, sealing performance is caused to decline, to be brought into steel pouring process below
Oxygen causes secondary oxidation of steel.
Invention content
The purpose of this utility model is in view of the problems of the existing technology, to provide one kind and can effectively solve the problem that junction is close
The long nozzle with anti-oxidation function of secondary oxidation of steel under the conditions of sealing and preventing height from even pouring.
The purpose of this utility model solves by the following technical programs：
A kind of long nozzle with anti-oxidation function, it is characterised in that：The rim of a bowl cavity wall of the long nozzle ontology is equipped with
The concave station of the rim of a bowl liner can be accommodated, the outer wall of the rim of a bowl liner matches with the cavity wall of the long nozzle ontology on the upside of concave station；It is described
It is surrounded with reinforcing rib on the rim of a bowl outer wall of long nozzle ontology, and structure is equipped in the junction of the rim of a bowl of long nozzle ontology and neck
The both ends of the surface of part, the structural member are combined with the rim of a bowl outer wall of long nozzle ontology and neck outer wall close and firm respectively so that structure
Part can be by the rim of a bowl and neck of suffered thrust profiles to long nozzle ontology, and the combination of reinforcing rib and structural member ensures long water
Sealing performance between mouthful ontology and collector nozzle of ladle above it.
The reinforcing rib is supreme to be provided with twice and central region in the rim of a bowl liner is arranged in wherein one of reinforcing rib.
The rim of a bowl liner is the cyclic annular frustum cone structure with cavity.
The angle of inclination of the bevel edge opposed vertical line of the rim of a bowl liner is 11 °.
The lower edge of the rim of a bowl liner is less than under the tapping hole lower edge and the inner wall and ladle of the rim of a bowl liner of collector nozzle of ladle
The tapping hole outer wall at the mouth of a river matches.
The utility model has the following advantages compared with prior art：
The utility model ensures long nozzle ontology and the collector nozzle of ladle above it by the setting of reinforcing rib and structural member
Between sealing performance, and the rim of a bowl liner with special shape structure seals to effectively solve junction and prevents height
Secondary oxidation of steel under the conditions of company pours, and then prevent secondary oxidation of steel from playing oxidizable member in the quality for improving steel, reduction steel
The oxidation product of element deposits to extend its service life in long nozzle inner wall, improves pouring the steel time and reducing long water for long nozzle
The consumption of mouth.
