Abstract
The utility model discloses a molten steel sampler used for sampling the molten steel in the process of steel making. The utility model comprises: a top cover is arranged on a barrel; a lifting stem is welded on the barrel wall; a heat preservation sleeve is stuck on the outer wall of the barrel; the inner cavity of the barrel is cylindrical. The sample produced by the utility model easily demolds, at the same time, can be used for analyzing the gas content and component content of the molten steel. The utility model has the advantages of shortening the sample time, improving the analyzing speed, simple production and low production cost.
Description
Technical field
The utility model relates to the sampler that a kind of liquid sampling is used, specifically a kind of molten steel sampler.
Background technology
Chinese patent ZL00218644.X discloses a kind of molten steel sampler, and its structure is at the cylindrical shell top cover that is provided with suitable for reading, is welded with shadoof on the barrel, and cylinder lumen is up big and down small rounding taper type cavity.After the sample thief demoulding of such sampler institute, wall is the inclined-plane, is not suitable for using the anchor clamps clamping.Also to be processed into during sample preparation and face directly, prolong the sample preparation time.In sampling process, because cylinder body outer wall directly contacts molten steel, so barrel thermal expansion occurs because of quick heating, and has the part inner-wall material to be melted in the molten steel sample.After sampling finished the proposition sampler, barrel contacted with atmosphere, then can meet cold contraction rapidly.Can therefore increase the difficulty of the molten steel sample demoulding like this, on the one hand; On the other hand, the barrel material of fusion penetrates into institute and gets in the molten steel sample, the feasible result of laboratory test misalignment of molten steel being made composition.In addition, because cylinder body outer wall is exposed, when sampler was passed the slag layer, outer wall can be stained with slag.In subsequent operation, these slags attached to outer wall may cause scuffing to operating personnel, thereby influence handling safety.Moreover, the processing technology complexity of this sampler, and adopt solid steel to make, manufacturing cost is higher.
The utility model content
The purpose of this utility model be exactly to provide a kind of be easy to the demoulding, analysis of components accurately, handling safety and manufacturing process is easy, cost is low molten steel sampler.
The utility model is achieved in that at the cylindrical shell top cover that is provided with suitable for reading the welding shadoof is bonded with heat insulation sheath on the outer wall of cylindrical shell on the barrel.This molten steel sampler is in the process that enters molten steel inside, because the heat-blocking action of heat insulation sheath, the barrel temperature variation is less, therefore, reduced Yin Gaowen and the inner-wall material of fusion to the pollution of molten steel sample, make made sample not only can be used to analyze the gas content of molten steel, can also be used to analyzing the component content of molten steel, and the stability of analysis result and accuracy obviously improve.And can avoid occurring causing the problem of demoulding difficulty because of the violent rising-heat contracting-cold of barrel, demolding rate reaches 100%.Because the buffer action of heat insulation sheath, the outer wall of sampler can not adhered to by slag, thereby has reduced the unsafe factor in the specimen preparation process.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1,, be welded with shadoof 3 on the cylinder body outer wall, be bonded with heat insulation sheath 2 on the outer wall of cylindrical shell 1 at cylindrical shell 1 top cover 4 that is welded with suitable for reading.Heat insulation sheath 2 is made by the thermostable heat insulation material.
The inner chamber of the cylindrical shell 1 of this molten steel sampler preferably is made for cylindrical.After the sample thief demoulding of this sampler institute, wall has saved the program of cut once more for suitable with the facing directly of anchor clamps clamping, has shortened the sample preparation time, has improved analysis speed, can effectively satisfy to make steel the needs of fast pace production.Because cylinder lumen of the present utility model is cylindrical, only need during manufacturing satisfactory steel pipe is disconnected by length, welding bottom, top cover and shadoof after polishing, get final product at outer wall bonding and thermal insulation sheath.Like this, not only saved turning manufacturing procedure to steel inside, and, because the price of steel pipe is far below the price of solid steel, so reduced manufacturing cost.
Claims (2)
1, a kind of molten steel sampler, at cylindrical shell (1) top cover (4) that is provided with suitable for reading, welding shadoof (3) on the barrel is characterized in that being bonded with heat insulation sheath (2) on the outer wall of cylindrical shell (1).
2, molten steel sampler according to claim 1 is characterized in that cylindrical shell (1) inner chamber is cylindrical.
