Description
Technical field
The utility model relates to the vacuum metling utensil, be specifically related to a kind of under vacuum state the device of automatic temperature measurement and liquid steel sampling.
Background technology
At present, under vacuum during metal smelting, in order to guarantee that molten metal remains under the vacuum state always, can't detect temperature and the composition of molten metal in the molten bath, such as molten steel in VOD external refining process, because the carbon content in the oxygen blast process in the molten steel is constantly to descend, to guarantee as far as possible that from process for making the temperature of the content of C the molten steel and molten steel is in target value, to guarantee carrying out smoothly of follow-up work link, so in reality, be starved of a kind of can be under vacuum state, extract a kind of device of molten steel sample and detection liquid steel temperature, detect where necessary liquid steel temperature, extract the sample of molten steel.But under present metallurgical equipment condition, if detect liquid steel temperature, extraction molten steel sample, must be under atmospheric condition, namely if detect liquid steel temperature in the vacuum metling process, extraction molten steel sample, must destroy after the vacuum, open temperature that vacuum container cover could detect molten steel, reach liquid steel sampling, cause and to smelt continuously, detection time is long, complicated operation; If sample composition and temperature do not reach metallurgical effect, existence also needs to restart vacuum apparatus or other equipment carries out again smelting operation to molten steel, the defective that also causes a large amount of wastes of the energy and productivity significantly to reduce.Under present technical qualification, the automatic temperature measurement sampling does not have the precedent of realization under the vacuum.Particularly be on some jumbo metallurgical furnaces, have because equipment volume is large the defectives such as the length of thermometric sampling gun and weight increase.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and cost is low, use and easy to operate, stable, not blowing out, to the thermometric of molten metal and sampling be achieved a kind of under vacuum state the device of automatic temperature measurement and liquid steel sampling.
In order to fill up the deficiencies in the prior art, the technical solution of the utility model is to solve like this: a kind of under vacuum state the device of automatic temperature measurement and liquid steel sampling by multistage hydraulic cylinder, body, temperature-measuring gun, sampling gun, equilibrator, sealing cover and handle hole form, special character of the present utility model is that described multistage hydraulic cylinder is fixedly installed in the body upper end, described temperature-measuring gun is connected linker and is connected with the piston rod of multistage hydraulic cylinder with sampling gun, the body lower end arranges respectively equilibrator, sealing cover and handle hole, described body bottom links to each other with smelting furnace by flange, wherein, the described temperature-measuring gun body interior that is connected with sampling gun is connected with the piston rod of multistage hydraulic cylinder with holder or screw thread by linker, described sealing cover is installed on body interior, and described body one side arranges a handle hole.
Described body is the container of independent closed.
Described handle hole and sealing cover are the step-by-step operation structure, and described stepped start-stop system is that both opening/closing times are out that one closes or one closes one and open, and both can not open simultaneously.
The utility model has solved under the vacuum state in the Metal smelting process, the sampling of molten metal and the test problems of temperature.Adopt multistage hydraulic cylinder as propulsion source, drive temperature-measuring gun and sampling gun, the temperature of measuring metallic solution under vacuum state in the insertion molten steel reaches takes a sample to molten metal.
The beneficial effects of the utility model are: adopt the multi-stage expansion hydro-cylinder as propulsion source, drive temperature-measuring gun and sampling gun, and pressure equaliser is set, so that thermometric and the sampling to molten metal is achieved under vacuum state.Solved for a long time in the Metal smelting process, can not be to the molten metal thermometric under the vacuum state and the difficult problem of sampling.
The utlity model has following characteristics;
1, device height is low.With respect to smelting furnace, this device is installed does not increase the smelting furnace total height, namely need not increase factory building height.
2, can realize once the operation of single rifle or multiple gun, improve production efficiency.
3, reliability is high, and this device is owing to adopting hydrostatic transmission, and is stable, the problems such as the shake when not having manual operation, and thermometric, sampling success ratio are high, are widely used in the Metal smelting industry.
