Abstract
The utility model relates to the technical field of smelting, in particular to a liquid steel sampling device which used for taking samples on the condition that chemical components of liquid steel and quality of liquid steel are guaranteed during a steelmaking secondary refining process. According to the liquid steel sampling device, a sample cup is of a cylindrical shape, the center of the sample cup is provided with a funnel hole, the profile of a plug is of a cone frustum shape, and the cone shape of the plug corresponds to the cone shape of the funnel hole of the sample cup. The liquid steel sampling device used for taking samples of the secondary steelmaking liquid steel has the advantages of achieving rapid taking out of molding steel samples, being simple in structure, achieving using convenience, saving 30 seconds of time, enabling success rate of sample taking to achieve 100%, enabling steel samples to be plump, dense in mass, smooth and free of pore, and enabling the liquid steel to be free of secondary oxidation, stable in chemical composition, free of environmental pollution, low in cost, and capable of being used repeatedly and the like. During a modern rapid rhythm steelmaking-continuous casting process, the liquid steel sampling device can rapidly save time, ensure quality of the steel, improve production efficiency, reduce labor intensity and greatly increase economic benefits.
Description
Technical field
The utility model relates to technical field of smelting, and specifically relating to a kind of double refining of making steel is the Steel liquid sampler for guaranteeing that molten steel chemical constitution and molten steel quality are taken a sample in the process.
Background technology
Double refining is the important step that steelmaking process guarantees molten steel chemical constitution and molten steel quality.The sample that in smelting process, is used for stokehold check chemical constitution then can be referred to as steelworker's eyes, is the important assurance of molten steel chemical constitution and quality.Sampling method in the double refining process tradition has: 1) the special-purpose ST of specialized factory's making; Main material is made up of sampling cup, quartz ampoule, sand cover, protection paper tube, tin hat etc.; Cost is high, produce volume of smoke during sampling, environmental pollution is serious, and the harm workman is healthy; And because ST is too little, be prone to the cavity in the middle of most of finished product appearance of taking out, the molten steel chemical constitution that analyzes is prone to higher, sulphur phenomenons on the low side such as common elements such as carbon, silicon, manganese, aluminium, field worker adjustment molten steel chemical constitution difficulty.2) sample spoon sampling; Transfer in the mould again the appearance spoon takes out molten steel from ladle after and pour into a mould, this process length consuming time, sample is exposed in the air oxidized easily; Fluctuation appears in composition; Be prone in the casting process produce gas sky and wrinkle, the spectral analysis chemical constitution is prone to deviation, and labour intensity is bigger.
Summary of the invention
The technical matters that the utility model will solve is to the deficiency that exists in the prior art, and a kind of Steel liquid sampler that is used for the sampling of double refining molten steel and takes out into shaped steel appearance fast is provided.
A kind of Steel liquid sampler of the utility model is achieved through following technical proposals: a kind of Steel liquid sampler, comprise appearance cup, plug, thief rod, and described appearance cup is cylindrical, its center has funnel hole; Described plug profile is a truncated cone, and its taper is corresponding with the funnel hole taper of appearance cup.
A kind of Steel liquid sampler of the utility model has following beneficial effect compared with prior art: the utility model ST is in use behind welding thief rod on the Steel liquid sampler appearance cup; Plug is put into the appearance cup; Mouth slowly inserts in the molten steel towards tilting 60～65 °, and insertion depth is that the centre does not stop more than the 250mm; Molten steel pours into appearance cup back and slowly takes out, sample time 4s～6s.
ST leaves standstill 15s～25s after from ladle, taking out on the ground, knocks ground gently, with plug steel appearance is ejected from ST, wait the steel appearance cooling of taking-up after, labelledly give laboratory processing, polishing check.A kind of Steel liquid sampler of the utility model is used for the sampling of double refining molten steel; Have take out into shaped steel appearance, simple in structure, convenient in application fast, 30s saves time; Getting into the rate height is 100%; And the full matter of steel appearance is close, smooth pore-free, molten steel do not have secondary oxidation, chemical composition stability, non-environmental-pollution, cost low, characteristics such as can use repeatedly.In the allegro in modern times steel smelting-continuous casting production run, can save time fast and guarantee steel quality, effectively enhance productivity, reduce labor strength, significantly increase economic efficiency.

Embodiment
Below in conjunction with accompanying drawing and embodiment a kind of Steel liquid sampler technical scheme of the utility model is further described.
Like Fig. 1-shown in Figure 5, a kind of Steel liquid sampler of the utility model comprises appearance cup 1, plug 3, thief rod 4, and described appearance cup 1 is cylindrical, and its center has funnel hole 2; Described plug 3 profiles are truncated cone, and its taper is corresponding with funnel hole 2 tapers of appearance cup 1.
Described appearance cup 1 one face down bondings are connected to thief rod 4.
1. after HJ-56-1 Steel liquid sampler appearance cup 1 one face down bondings connect the thief rod 4 that the long diameter of 4m is φ 20mm; It is as shown in Figure 5 that plug 3 is put into appearance cup 1; Hand-held thief rod 4 tilts 2 mouthfuls of courts of funnel hole 60～65 ° and slowly inserts in the molten steel, and insertion depth is that the centre does not stop more than the 250mm; Slowly take out, sample time 4s～6s.
2. after ST takes out, leave standstill 15s～25s on the ground from ladle, knock ground gently, upwards slide along the inclined-plane of funnel holes 2 with plug 3 steel appearance is ejected from ST, wait the steel appearance cooling of taking-up after, labelledly give laboratory processing, polishing check.
3. molten steel temperature must be in sampling more than 1450 ℃.
4. a kind of Steel liquid sampler of the utility model only is used for the sampling of double refining process molten steel.Need not operations such as baking during sampling.
5. the degree of depth, the time in the Steel liquid sampler insertion molten steel is wanted the strict Steel liquid sampler regulation of pressing.
A kind of Steel liquid sampler thief rod of the utility model also can be welded on the top of appearance cup.
