Description
Technical field
This utility model relates to liquid steel sampling detection technique field, particularly relates to a kind of Fructus Amomi molten steel sampler.
Background technology
Liquid steel sampling is to take out rapidly sample preparation in liquid molten steel, quickly analyzes for spectrum, thus obtains this stove molten steel
The situation such as component, homogeneity, is used for instructing smelting process.Accurate acquisition is to the basic premise of the data such as liquid steel temperature and component
It is, the shortest from the time being sampled to obtain analysis result.If sample rate is slow, then the analysis result of accurate instrument is also
Without reference to being worth.Therefore, sample rate is crucial, and developing sampler easy, quick is spectrum analysis before converter
The key of success.Traditional sampler is that sample box is wholly embedded into central authorities in paper bushing, and is blocked by sample box, then exists
Chapeau de fer is covered on paper bushing port.This sampler drawback is more, and sample box is wholly embedded in papery sleeve pipe and is unfavorable for that sample preparation is quick
Heat radiation, sample preparation molding is slow, normal sampling need 8 seconds the most longer.All being stuck in papery sleeve pipe with up-to-date style box major part, sample preparation is difficult
To take out, add labor intensity and the time of sampling detection.
And, the aerofluxus that the breathability deficiency of traditional refractory layer used by sampler also results in sampling box is not smooth, from
And sampling the fullest, sample block has impurity, surface to have pore, and success rate is low.
The patent of Application No. 201410275687.X, discloses a kind of device simultaneously sampling thermometric.Described take simultaneously
The device of sample thermometric includes frame and is arranged on the temperature probe in described frame and sampling probe.This samples thermometric simultaneously
Device one-off can realize thermometric and sampling simultaneously, can not only ensure that thermometric and sample analysis result are all for same
The molten steel of time point, but also the time of thermometric sampling can be greatly saved, improve efficiency, great prospects for commercial application.But
Being that the device sampling thermometric while this application designs still exists many deficiencies, said apparatus needs to arrange frame, and should
Frame needs enough spaces and arranges temperature probe and sampling probe, and it is complicated that this allows for global design, adds and is manufactured into
This.On the other hand, frame itself can increase the weight of sampler, so can increase the cost in terms of transport.This Novel sampling device
The when of operative, simultaneously need to the Novel sampling device of burden tradition individually sampler weight 2-4 times, the health element to workman
Matter, the stability of operation all bring stern challenge.
Utility model content
