Description
The utility model relates in a kind of metal smelt and the casting process, is used for the disposable utensil of finishing thermometric and sampling, thermometric and sampling when being particularly useful for molten steel.
Determine because detection meanss such as spectral analysis or x-ray fluorescence analysis are used in the improvement of smelting technique, the chemical analysis of molten steel mostly instead, so just proposed a requirement that desirable sample is provided fast.At present, domesticly occurred some and directly inserted in molten steel utensils of sampling fast, but smelt and casting cycle in, existing thermometric and sampling be the employing way of carrying out respectively all.I.e. people's thermometric, people sampling, not only waste of manpower, material resources operates cumbersomely and inconvenient, and because thermometric and sampling difference in time, these parameters easily cause difficulty in the reference in smelting process controlling party face.
Though present domestic existing thermometric carbometer, it can not finish the detection of other chemical analysis in the copper water, and structure is also different.If other chemical analysis in the detection molten steel also needs other sampling, this as many as repetitive operation has so just increased production cost.
In view of the problems referred to above that exist, the purpose of this utility model is that to seek a kind of cost low, can be fast, the accurate and plug-in type liquid metal thermometric sampler that can carry out thermometric and sampling simultaneously.
For realizing the purpose of this utility model, the technical measures of being taked are a kind of plug-in type liquid metal thermometric sampler of design, it is characterized in that it is made up of cover paper web (2), sampling cup (4), thermopair (5), refractory matter sealant (6), dust cap (7), shelves slag cap (8), metallic contact plate (9) in the plug-in type overcoat paper web (1), plug-in type; Sampling cup (4) and thermopair (5) are installed in of interior cover paper web (2) side by side, and they are fixed in the paper web mouth with refractory matter sealant (6), the quartz ampoule of sampling cup (4) entangles with dust cap (7), the shelves slag caps (8) that are fixed on the refractory matter sealant (6) cover on the nozzle of interior cover paper web (2), the centre of cover paper web (2) in metallic contact plate (9) is fixed on, the compensating wire of thermopair (5) is connected with metallic contact plate (9); When the contact of the control lever that connects temperature instrumentation with after the metallic contact plate (9) of sampler is connected, when placing liquid metal to take a sample, can finish the thermometric and the sampling work of liquid metal simultaneously.
This plug-in type liquid metal thermometric sampler, cost is low, can measure the temperature of liquid metal quickly and accurately, check and analysis for every chemical analysis of liquid metal simultaneously provide a desirable sample fast, and provide desirable comparable data for the control of smelting process, also can save human and material resources greatly in addition, simplify simultaneously and made things convenient for operation, alleviate labor intensity of operating personnel.
Fig. 1 is the one-piece construction figure of plug-in type liquid metal thermometric sampler.
Fig. 2 is the structural representation of sampling cup among Fig. 1 (4)
Introduce technology contents of the present utility model in detail below in conjunction with drawings and Examples.
Embodiment is a sample with the molten steel.
As shown in Figure 1, plug-in type liquid metal thermometric sampler is by cover paper web (2), sampling cup (4), thermopair (5) in plug-in type overcoat paper web (1), the plug-in type, and refractory matter sealant (6), dust cap (7), shelves slag cap (3), metallic contact plate (9) are formed.A width and a length symmetry according to sampling cup (4) at interior cover paper web (2) is driven two open slots (3), and sampling cup (4) iron chains are embedded in the open slot (3).Thermopair (5) is installed side by side in a side of sampling cup (4), and in being fixed on refractory matter sealant (6) in cover paper web (2), only make the quartz ampoule of the U type quartz ampoule of thermopair (5) and sampling cup (4) be exposed at the outside of refractory matter sealant (6), and the nozzle of interior cover paper web (2) sealed, in case in the molten steel people.The quartz ampoule of sampling cup (4) rim of a cup is past with dust cap (7) cover, in going into dust protection, has guaranteed the purity of molten steel.Slag retaining cap (8) be fixed on refractory matter sealant (6) above, covered the nozzle of interior cover paper web (2), live entering of slag with shelves, guaranteed the purity of molten steel too.Dust cap (7) and shelves slag caps (8) all are punching of the steel plate, when sampler enters the molten steel certain depth, can melt voluntarily, and pure molten steel is successfully entered in the sampling cup (4).The middle symmetry of interior cover paper web (2) is equipped with two metallic contact plates (9), and two compensating wires of thermopair (5) are connected in respectively on two metallic contact plates (9).
As shown in Figure 2, thermopair (5) is by fire resistive material skeleton (10), compensating wire (11), and platinum rhodium 10 (12) and U type quartz ampoule (13) are formed.Two of platinum rhodium 10 (12) in the U type quartz ampoule (13) is connected with two compensating wires (11) respectively, and they are fixed in the fire resistive material skeleton (10), the part U type quartz ampoule (13) that exposes in fire resistive material skeleton (10) outside is used for and the molten steel contact thermography, and two compensating wires (11) of drawing fire resistive material skeleton (10) outside are connected with two metallic contact plates (9) respectively.
As shown in Figure 3, sampling cup (4) is to be fastened by the garden shape half cup mould (14) of two band rims of a cup and (16) to form, and two half cup moulds (14) and (16) have vent port (15) and (17) in rim of a cup center symmetria bilateralis respectively at the bottom of cup, be used for exhaust.Quartz ampoule (19) is fixed in the rim of a cup with refractory matter sealing layer (13).Cover paper web (2) was when interior in this sampling cup (4) was installed in, and quartz ampoule (19) was exposed at the outside of refractory matter sealant (6), can avoid molten steel to cling rim of a cup like this.
During operation, the control lever that links to each other with temperature instrumentation can be inserted in the interior cover paper web (2) of sampler, contact is contacted with metallic contact plate (9), when the sampler other end being inserted when going and being deep into the 250-300 millimeters deep in the molten steel, shelves slag caps (8) at first melt, at this moment behind the part U type quartz ampoule (13) of thermopair (5) the contact molten steel, thermopair (5) is started working, dash silk (12) by the platinum rhodium, compensating wire (11), metallic contact plate (9), the contact of control lever, lead, pyroelectric signal is passed to temperature instrumentation, make instrument demonstrate the temperature of molten steel, so just finished thermometric work fast.Meanwhile, the dust cap (7) that is with on the quartz ampoule (19) of sampling cup (4) rim of a cup has also melted, molten steel enters sampling cup (4) inner chamber crystallization through quartz ampoule (12), and the air in the cup is discharged by vent port (15) and (17), so just can obtain a desirable molten steel sample.
