Description
Technical field
Field of steel metallurgy is the utility model is related to, particularly relates to a kind of liquid steel sampling cup of stokehold oxygen nitrogen hydrogen analysis detection
Device.
Background technology
Oxygen nitrogen hydrogen is the important composition parameter of stainless steel smelting, molten steel need to be taken in time in smelting process
Sample, after molten steel forms rod iron, segment is placed in analyzer and analyzed.The analysis of existing oxygen nitrogen hydrogen, mostly it is in refining or continuous casting
Vacuum tube sampling analysis is used in crystallization process, specifically, vacuum tube openend is placed in molten steel, is then sucked molten steel true
In blank pipe.However, comprehensive detection also requires to carry out the oxygen nitrogen hydrogen analysis of stokehold, refined because stokehold liquid steel temperature is relative
Or during continuous casting crystallining liquid steel temperature will height, vacuum tube is placed in to turn furnace inner sampling difficulty big, and molten steel is suction vacuum tube
Interior, because lacking deposition between molten steel and vacuum inside pipe wall, and make it that the rod iron surface that molten steel ultimately forms after cooling down is smooth
Spend poor, the oxide layer that surface is formed is more intractable, is unfavorable for the detection and analysis of postorder, and sampling success rate is low.
The content of the invention
The purpose of this utility model is to provide a kind of liquid steel sampling cupule of stokehold oxygen nitrogen hydrogen analysis detection.
Realizing the technical scheme of the utility model purpose is, a kind of liquid steel sampling cupule of stokehold oxygen nitrogen hydrogen analysis detection,
Including the cup with penetrating inner chamber and molten steel to be poured into the sample spoon of cup inner chamber, cup inner chamber by being taken out in converter
Buildup chamber including top and the forming cavity being connected positioned at lower section with buildup chamber, forming cavity is in top diameter is big, lower section is straight
The small gradual change shape column in footpath, buildup chamber base diameter are more than forming cavity maximum gauge.
Further, buildup chamber is coniform in top diameter is big, diameter below is small.In this way, make buildup chamber upper opening
It is larger, facilitate feeding spoon by molten steel by pouring into buildup intracavitary after being taken out in converter, the molten steel in feeding spoon is not easy because on buildup chamber
Square too small openings, and can not accurately pour into.
Further, cup body outer wall has inner groovy.In this way, facilitating holding for cup to take, pick and place and move, avoid outside cup
Wall is excessively smooth and is difficult to put forth effort, and causes to slide.
The liquid steel sampling cupule of the utility model stokehold oxygen nitrogen hydrogen analysis detection, before sampling, forming cavity lower end is sealed, taken
During sample, the molten steel in converter is taken out with sample spoon, and pours into the buildup intracavitary of cup, the molten steel of buildup intracavitary flows into down successively
In the forming cavity of side, deposited in forming cavity, form rod iron after cooling, the liquid steel sampling cup of this kind of stokehold oxygen nitrogen hydrogen analysis detection
Device, molten steel are taken out by sample spoon, and sample spoon length is longer, and operating personnel can be operated away from the converter of high temperature, and operation is feasible
Property it is high, and the molten steel that sample spoon takes out first pours into the big buildup intracavitary of diameter, then flows into forming cavity, and buildup chamber plays injection bucket
Effect, efficiently solves forming cavity because diameter is smaller, molten steel directly can not easily pour into the problem of its is interior in sample spoon, together
When, because forming cavity is in the gradual change shape column that top diameter is big, diameter below is small, shaping cavity wall bears its interior molten steel part weight
Power, in this way, the molten steel flowed into forming cavity is more densely deposited on shaping cavity wall, final molding in the presence of its gravity
Rod iron surface flatness it is good, no pit, inside enrich, pore-free, surface formed oxide layer it is disposable, sample success rate
Height, and forming cavity lower end is penetrating, it is convenient to use the structures such as push rod by shaping when by the rod iron of shaping by being taken out in forming cavity
Rod iron ejects, that is, facilitates the demoulding of rod iron.
Brief description of the drawings
Fig. 1 is the structural representation of the cup of the liquid steel sampling cupule of the utility model stokehold oxygen nitrogen hydrogen analysis detection；
Fig. 2 is the structural representation of the sample spoon of the liquid steel sampling cupule of the utility model stokehold oxygen nitrogen hydrogen analysis detection.
Embodiment
As depicted in figs. 1 and 2, a kind of liquid steel sampling cupule of stokehold oxygen nitrogen hydrogen analysis detection, including with penetrating inner chamber 1
Cup 10 and molten steel is poured into the sample spoon 20 of cup inner chamber 1 by being taken out in converter, cup inner chamber 1 includes top
Buildup chamber 11 and the forming cavity 12 being connected positioned at lower section with buildup chamber 11, forming cavity 12 is in top diameter is big, diameter below
Small gradual change shape column, the base diameter of buildup chamber 11 are more than the maximum gauge of forming cavity 12.Buildup chamber 11 is in top diameter is big, lower section
Small coniform of diameter.The outer wall of cup 10 has inner groovy 101.
The liquid steel sampling cupule of the utility model stokehold oxygen nitrogen hydrogen analysis detection, before sampling, the lower end of forming cavity 12 is sealed,
During sampling, the molten steel in converter is taken out with sample spoon 20, and pours into the buildup chamber 11 of cup 1, the molten steel in buildup chamber 11
Flow into successively in the forming cavity 12 of lower section, rod iron is formed after deposition, cooling in forming cavity 12.
The liquid steel sampling cupule of the utility model stokehold oxygen nitrogen hydrogen analysis detection, molten steel are taken out by sample spoon 20, sample spoon
20 length are longer, and operating personnel can be operated away from the converter of high temperature, and operation possibility is high, and the molten steel that sample spoon 20 takes out
First pour into the big buildup chamber 11 of diameter, then flow into forming cavity 12, buildup chamber 11 plays injection bucket, efficiently solves into
Die cavity 12 is because diameter is smaller, and molten steel directly can not easily pour into the problem of its is interior in sample spoon 20, meanwhile, because forming cavity 12 is in
The gradual change shape column that top diameter is big, diameter below is small, the inwall of forming cavity 12 bear its interior molten steel part gravity, in this way, stream
Enter the molten steel in forming cavity 12 in the presence of its gravity, be more densely deposited on the inwall of forming cavity 12, the rod iron of final molding
Surface flatness is good, no pit, and inside is enriched, pore-free, and the oxide layer that surface is formed is disposable, and sampling success rate is high, and into
The lower end of die cavity 12 is penetrating, convenient to use the structures such as push rod by the steel of shaping when by the rod iron of shaping by being taken out in forming cavity 12
Rod ejects, that is, facilitates the demoulding of rod iron.
The liquid steel sampling cupule of the utility model stokehold oxygen nitrogen hydrogen analysis detection, to make the upper opening of buildup chamber 11 larger,
Facilitate feeding spoon 20 by molten steel by being poured into after being taken out in converter in buildup chamber 11, the molten steel in feeding spoon 20 is not easy because of buildup chamber 11
Upper opening is too small, and can not accurately pour into, it is preferred that buildup chamber 11 is coniform in top diameter is big, diameter below is small；For
Facilitate holding for cup 10 to take, pick and place and move, avoid the outer wall of cup 10 excessively smooth and be difficult to put forth effort, cause to slide, it is preferred that
The outer wall of cup 10 has inner groovy 101.
The liquid steel sampling cupule of the utility model stokehold oxygen nitrogen hydrogen analysis detection, before sampling, asbestos can be used by forming cavity
12 lower ends seal.
