The sample is conveniently taken out by demoulding without needing knocking during demoulding, the device has low scrap rate and long service life, the number of spare parts is reduced, and the use cost is low. The graphite material is low in cost and easy to process and has lower purchasing and processing costs than steel, so that the manufacturing cost is reduced. The cup-shaped molten iron sampling device is suitable for molten iron sampling in the blast furnace smelting process.

Description

Cup sections water-sampling device

Technical field

The utility model relates to field of metallurgy, especially a kind of glass of sections water-sampling device.

Background technology

In the blast furnace process production run, all need molten iron is taken a sample, by the molten iron sample is carried out spectral analysis, analyze the chemical constitution of molten iron.Traditional molten iron sampler is generally a glass shaped steel spare, comprises sampler barrel and base plate.During sampling, sampler barrel is positioned on the base plate, with the sample spoon molten iron is poured in the sampler barrel then, after the cooling molten iron sample is poured out.Sampler barrel, base plate are foundry goods, its rough surface, and washed away by molten iron, therefore easy and molten iron sample forms adhesion, hinders the taking-up of molten iron sample; Simultaneously, because when pouring molten iron into by the sample spoon, pouring volume is wayward, easily causes molten iron to overflow, and makes cooling back molten iron sample and sampler barrel be connected as a single entity and can't pour out.During sampling, usually need knock, by making each several part separate to base plate, sampler barrel, impacting of molten iron sample, therefore the labour intensity of taking a sample is big, in the process of knocking, damage easily sampler and cause scrapping, collapse the chip that flies and collapse easily and hinder operating personnel, when taking out the molten iron sample by knocking, sampler barrel, base plate top layer adhere to molten iron sample surface easily or are torn, and cause sampler barrel, base plate to use.Therefore, existing sampler scrappage height, spare part quantity is big, the use cost height.

The utility model content

Technical problem to be solved in the utility model provides a kind of molten iron sample demoulding sampling conveniently, and scrappage is low, the cup sections water-sampling device that make, use cost is low.

The technical scheme that its technical matters that solves the utility model adopts is: cup sections water-sampling device, comprise sampler barrel and base plate, and described sampler barrel and base plate all adopt graphite to make, and described sampler barrel is one-body molded with base plate or stick with paste by carbon element and to fixedly connected.

As a kind of preferred, described sampler barrel and base plate are one-body molded, and described sampler barrel inner chamber is up big and down small circular platform type.

Further, be provided with by clip and be fixed on handle reverse on the sampler barrel.

The beneficial effects of the utility model are: graphite material is high temperature resistant, chemical stability good, and thermal conductivity surpasses metal materials such as steel, iron, lead, and thermal expansivity is little, the variation of ability rapid heat cycle, and the molten iron sample size that obtains is accurate, any surface finish and yield rate height.Graphite material also is a kind of lubricant simultaneously, will install upset, shake during the demoulding, and the landing voluntarily of molten iron sample need not to knock, so demoulding sampling is convenient, and the device scrappage is low, and service time is long, and spare part quantity is few, and use cost is low.Low, the easy processing of graphite material cost, buying, processing cost all are lower than steel, so cost of manufacture is low.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As shown in Figure 1, cup of the present utility model sections water-sampling device comprises sampler barrel 1 and base plate 2, and described sampler barrel 1 and base plate 2 all adopt graphite to make, and described sampler barrel 1 and base plate 2 are one-body molded or stick with paste by carbon element and to fixedly connected.

Graphite material is high temperature resistant, chemical stability good, and thermal conductivity surpasses metal materials such as steel, iron, lead, and thermal expansivity is little, the variation of ability rapid heat cycle, and the molten iron sample size that obtains is accurate, any surface finish and yield rate height.Graphite material also is a kind of lubricant simultaneously, need not during the demoulding to knock, so demoulding sampling is convenient, and the device scrappage is low, and service time is long, and spare part quantity is few, and use cost is low.Low, the easy processing of graphite material cost, buying, processing cost all are lower than steel, so cost of manufacture is low.

Sampler barrel 1 and base plate 2 are stuck with paste when fixedlying connected by carbon element, can be set to up-small and down-big circular platform type by sampler barrel 1 inner chamber, it is more reasonable that the molten steel solidification temperature field of this inner chamber distributes, but sampling is need at first destroy carbon element to stick with paste material, separate sampler barrel 1 and base plate 2, operation shows slightly loaded down with trivial details, and molten iron sample less demanding for mechanical property, mainly is to avoid cracking and pore.The exhaust and convenient of cup type structure own, therefore pore formation probability is little, simultaneously because the small size of molten iron sample and the high-termal conductivity of graphite material, adopt equal diameter cylindrical cavity or up big and down small circular platform type inner chamber not remarkable to the influence of temperature of solidification field, can avoid cracking equally, and can by to the optimization of the wall thickness of the gradient of circular platform type inner chamber, sampler barrel 1 further reduction to the influence of temperature of solidification field.For simplified structure and operation, in example as shown in the figure, described sampler barrel 1 and base plate 2 are one-body molded, and described sampler barrel 1 inner chamber is up big and down small circular platform type, will install upset, shake during the demoulding, the landing voluntarily of molten iron sample.

In order to further facilitate sampling, be provided with by clip 3 and be fixed on handle reverse 4 on the sampler barrel 1.
