Special cooling device for steel sample

Technical Field

The utility model relates to a steel smelting technical field especially relates to a special cooling device for steel sample detects.

Background

At present, most of rapid analysis systems in the domestic metallurgical industry manually analyze and test samples, so that the labor efficiency is low, the cost is high, and the analysis data is not fast enough. The field analysis and detection of the metallurgical enterprise currently has three working modes of off-line analysis, on-line analysis and on-line analysis. Some enterprises in developed countries adopt an online analysis mode, an analysis system is close to a production field, and a test result is quickly transmitted or displayed after a sample is quickly prepared and analyzed. The analytical equipment used by them is highly automated but expensive. At present, steel enterprises in China have a multi-purpose off-line analysis mode.

When a spectrum sample is manufactured, the spectrum sample has good representativeness, the analysis surface is uniform, and the sample is free of air holes, sand holes, cracks, impurities and the like after being prepared. Generally, an analysis sample obtained by a steel mill is mainly in a table tennis bat or a cylindrical shape, and due to various reasons such as poor quality of a sampler, imperfect sampling method, imperfect sample preparation method and the like, the surface of a medium-high carbon steel sample often has defects such as air holes, sand holes and the like, the sample analysis qualification rate is 95%, the total is low, and the production rhythm and quality are influenced. The cooling mode of the test piece is a more critical control point, the traditional air cooling mode is slow in cooling, but can not be quenched by water, and great influence is generated on a molten steel solidification structure, so that a device for improving the air cooling efficiency is needed to be researched.

SUMMERY OF THE UTILITY MODEL

For overcoming the deficiencies of long time consumption, low efficiency and the like of the prior direct air cooling, the utility model aims to solve the technical problems that: provides a special cooling device for steel samples, which can improve the air cooling efficiency.

The utility model provides a technical scheme that its technical problem adopted is:

the special cooling device for the steel sample comprises a cooling cabin, an openable cabin door is arranged on the side face of the cooling cabin, an air blowing pipeline capable of introducing compressed air is arranged at the top of the cooling cabin, and a plurality of air exhaust holes are formed in the bottom of the cooling cabin.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, the utility model discloses a special cooling device of steel sample, including cooling cabin 1, the side of cooling cabin 1 is equipped with hatch door 2 that can open, and the top of cooling cabin 1 is equipped with the gas blow pipeline 3 that can let in compressed gas, and the bottom of cooling cabin 1 is equipped with a plurality of exhaust holes 4.

The traditional air cooling mode is that a steel sample is directly placed in a slow cooling pit for slow cooling, and because equipment such as a crystallizer is not arranged, the cooling speed of the steel sample is low in the cooling process due to solidification structures, so that the defects such as air holes, sand holes, cracks and inclusions are easy to occur.

Adopt the device of this application, usable blowing pipeline 3 lets in compressed gas to cool off the steel sample of the inside toward cooling chamber 1, and the compressed gas flow is big, and is fast, can take away the heat in cooling chamber 1 fast from exhaust hole 4 to improve the cooling efficiency of steel sample. Meanwhile, the high-pressure gas can clean dust, impurities and the like on the surface of the steel sample, so that the purity of the steel sample is ensured, and the subsequent detection is facilitated.

For ease of manufacture and improved space efficiency, the cooling module 1 is preferably cylindrical. The cabin door 2 should be as large as possible so as to take steel samples, one side of the cabin door 2 is hinged to the cooling cabin 1, and the other side of the cabin door is connected with the cooling cabin 1 through the buckle structure 5 so as to prevent the steel samples from falling.

When the steel sample is cooled, the cooling time needs to be accurately controlled, and the air blowing pipeline 3 can be provided with a valve 6, so that the steel sample can be conveniently started and stopped at any time.

Further, according to the size of the steel sample, in order to improve the cooling efficiency, the pipe diameter of the air blowing pipeline 3 should be not less than 5mm, so that the gas dispersion is ensured, and the contact area with the steel sample is improved. In order to enable gas to be discharged smoothly, the number of the exhaust holes 4 is 6-8, and the aperture of each exhaust hole 4 is 1-2 mm, so that the requirement that impurities such as dust fall is met.

The utility model discloses a put into the cooling chamber with the steel sample, utilize the gas blow pipeline at cooling chamber top to go into compressed gas and blow the air cooling to the steel sample, can improve the air and take away thermal efficiency to steel sample cooling is accelerated, and high-pressure gas can clear up the dust impurity on steel sample surface simultaneously, has fine practicality and application prospect.
