Abstract
A kind of pick-up unit for conticaster protection tube argon flow amount; it is mainly comprised of defeated argon pipe, the flowmeter one being connected with defeated argon pipe, the argon efferent duct being connected with flowmeter one, the mechanical arm connecting pipe being connected with argon efferent duct, the flexible pipe being connected with argon efferent duct and mechanical arm connecting pipe, argon envelope seat, the protection tube that is connected with argon envelope; it adds and is stamped U-shaped seal closure in the argon envelope seat upper end being connected with protection tube; medial surface and upper surface at U-shaped seal closure are connected with sealing gasket, in the upper surface of U-shaped seal closure, are communicated with flowmeter two.Argon flow amount in the on-line automatic accurate detection conticaster protection tube of the utility model energy, labour intensity significantly reduces, and can observe in time argon flow amount situation in protection tube, improves casting quality, prevents security incident generation, and simple in structure, easy to operate.
Description
Technical field
The utility model relates to a kind of pick-up unit, specifically belongs to the pick-up unit for conticaster protection tube argon flow amount.
Background technology
Casting low-carbon (LC) aluminium Series Steel ALS damages the ratio of large average △ Als≤150pp and only has 70%z left and right.Especially after reforming continuous casting machine, its automatization level is reached advanced world standards, but can not meet the demands to the detection of conticaster protection tube argon flow amount, and problem is very outstanding.
At present, the detection of conticaster protection tube argon flow amount adopts artificial experience inspection, and its inspection is the phenomenon that checks for leaks from argon gas input end to output terminal protection tube, and is to determine with feel.But in producing, often have two kinds of situations can cause protection tube argon flow amount not reach production requirement: the one, pipeline has leakage or stops up; The 2nd, because clear burning in protection tube has steel or slag to stop up protection tube seal closure ar gas passage.About detecting, owing to being the condition of high temperature in steel pouring process, manually cannot remove to experience argon flow amount with hand, otherwise unfavorable to operator's health, and there is potential safety hazard, therefore cannot detect in time.Therefore, only know the argon flow amount of inputting in protective casting system and do not know the argon flow amount that protection tube is exported.Finally will affect the control of lower stove molten steel composition.And the numerical value that argon gas stream scale shows only represents the flow after table, can not represent real argon flow amount in protection tube.If exist and reveal in argon gas pipeline, the flow of the argon gas at protection tube place and pressure will not reach the requirement of protective casting so.Between protection tube and collector nozzle of ladle, just can not form inert gas atmosphere.In casting cycle, because protection tube flow reduces, produce natural aspiration, and by air intake, make airborne oxygen and Als in molten steel react formation and be mingled with, this kind of situation also can form oxidisability and be mingled with and affect slab quality affecting molten steel composition.
Utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and surplus argon gas in the on-line automatic accurate detection conticaster protection tube of a kind of energy is provided, and labour intensity significantly reduces, and prevents the pick-up unit for conticaster protection tube argon flow amount of security incident.
Realize the technical measures of above-mentioned purpose:
A kind of pick-up unit for conticaster protection tube argon flow amount; it is mainly comprised of defeated argon pipe, the flowmeter one being connected with defeated argon pipe, the argon efferent duct being connected with flowmeter one, the mechanical arm connecting pipe being connected with argon efferent duct, the flexible pipe being connected with argon efferent duct and mechanical arm connecting pipe, argon envelope seat, the protection tube that is connected with argon envelope; it is: in the argon envelope seat upper end being connected with protection tube, add and be stamped U-shaped seal closure; medial surface and upper surface at U-shaped seal closure are connected with sealing gasket, in the upper surface of U-shaped seal closure, are communicated with flowmeter two.
It is characterized in that: in protection tube bottom, stopper is housed.
Feature of the present utility model: argon flow amount in the on-line automatic accurate detection conticaster protection tube of energy, labour intensity significantly reduces, and can observe in time argon flow amount situation in protection tube, improves casting quality, prevents security incident generation, and simple in structure, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-defeated argon pipe, 2-flowmeter, one, 3-argon efferent duct, 4-mechanical arm connecting pipe, 5-flexible pipe, 6-argon envelope seat, 7-protection tube, 8-U-shaped seal closure, 9-flowmeter, two, 10-sealing gasket, 11-stopper.
Embodiment
Below in conjunction with accompanying drawing, be described further:
A kind of pick-up unit for conticaster protection tube argon flow amount, it is mainly by defeated argon pipe 1, the flowmeter 1 being connected with defeated argon pipe 1, the argon efferent duct 3 being connected with flowmeter 1, the mechanical arm connecting pipe 4 being connected with argon efferent duct 3, the flexible pipe 5 being connected with argon efferent duct 3 and mechanical arm connecting pipe 4, argon envelope seat 6, form with argon envelope seat 6 protection tubes that are connected 7, it adds and is stamped U-shaped seal closure 8 in argon envelope seat 6 upper ends that are connected with protection tube 7, medial surface and upper surface at U-shaped seal closure 8 are placed with sealing gasket 10, upper surface at U-shaped seal closure 8 adopts bolt or the embedded flowmeter 29 that is communicated with.
In protection tube 7 bottoms, stopper 11 is housed.
Testing process is in the off time of changing ladle, and stopper 11 plugs, in protection tube 7 bottoms, are covered on U-shaped seal closure 8 on the argon envelope seat 6 of protection tube 7 connections.As found, the flow of flowmeter 29 and the flow of flowmeter one 2 demonstrations are without corresponding relation, illustrate that argon flow amount will start by this device progressively being examined and found the cause forward direction from flowmeter 1 extremely, be that pipeline is revealed or protection tube ar gas passage stops up.So just can accurately measure the argon gas real traffic of argon shield system.
This embodiment only exemplifies for the best, not the restricted enforcement to technical solutions of the utility model.
