Description
Technical field
The thermometric that the utility model uses when relating to smelting iron and steel and sampling instrument, be specifically related to a kind of device that simultaneously can realize sampling and thermometric.
Background technology
Liquid steel sampling takes out sample preparation rapidly in liquid molten steel, for spectrum express-analysis, thus obtains the situation such as component, homogenieity of this stove molten steel, be used to guide smelting process.Accurate acquisition to the basic premise of the data such as liquid steel temperature and component is, from being sampled to, the time obtaining analysis result is short as far as possible.If sample rate is slow, then the analysis result of accurate instrument does not have reference value yet.Therefore, sample rate is crucial, develop easy, fast sampler be the key of spectral analysis success before converter.Traditional sampler sample box is all imbedded central authorities in paper bushing, and blocked by sample box, then on paper bushing port, covers chapeau de fer.This sampler drawback is more, and sample box is all imbedded in papery sleeve pipe and is unfavorable for sample preparation quick heat radiating, and sample preparation is slowly shaping, and normal sampling needs 8 seconds are even longer.All be stuck in papery sleeve pipe with up-to-date style box major part, sample preparation is difficult to take out, and adds the time of labour intensity and sampling detection.
Liquid steel temperature is the important smelting parameter in present steel industry smelting process.The direct motion of guarantee continuous casting production process, reduction raw materials consumption and energy consumption, raising slab quality are had a great impact.It is steel mill system running stability " barometer " that temperature controlled water is put down.The measurement of liquid steel temperature is also a vital link.
In traditional steel smelting procedure, liquid steel sampling and thermometric carry out at twice.Liquid steel sampling mainly relies on single sampler, is first enclosed within sampler by sampler during sampling, and sampler is immersed molten steel by decline sampler, and lifting sampler is taken sampler out of and got tapping sample.After having sampled, liquid steel temperature measured by reusable heat galvanic couple.Be subject to molten steel liquid level fluctuation and the impact of twice operation, the liquid steel sampling degree of depth and the temperature survey degree of depth probably inconsistent, measure temperature and can not characterize sampling molten steel exactly, and then affect analysis and the judgement of data.Liquid steel sampling and thermometric also bring another problem at twice, and operation steps is many, length consuming time, have a strong impact on molten steel composition and rhythm of production control, far can not adapt to the requirement of smelting iron and steel tempo increase.
Application number is the patent of 201410275687.X, discloses a kind of device simultaneously sampling thermometric.The described device simultaneously sampling thermometric comprises frame and the temperature probe that is arranged in described frame and sampling probe.This device one-off simultaneously sampling thermometric can realize thermometric and sampling simultaneously, can not only ensure that thermometric and sample analysis result are all the molten steel for same time point, but also greatly can save the time of thermometric sampling, improve efficiency, have prospects for commercial application.But while this application design, the device of sampling thermometric still exists many deficiencies, and said apparatus needs to arrange frame, and this frame needs enough spatial placement temperature probes and sampling probe, this just makes global design complicated, adds manufacturing cost.On the other hand, frame itself can increase the weight of sampler, can increase the cost of transport aspect like this.When this Novel sampling device operative, need to bear tradition sampler weight 2-4 Novel sampling device doubly separately simultaneously, all stern challenge is brought to the fitness of workman, the stability of operation.
Summary of the invention
For there is the shaping comparatively slow problem of not easily taking out of liquid steel sampling and the thermometric duration of heat that separately waste is valuable and sample preparation in prior art, and in order to sample the structure of the device of thermometric disclosed in simplifying simultaneously, the utility model provides a kind of measuring temp of molten steel and sampler, it can realize carrying out liquid steel sampling and thermometric simultaneously, and volume is little, simple structure, on the basis winning the how valuable steel-making time, reduce costs, save labour.
The purpose of this utility model is achieved through the following technical solutions.
