Description
Technical field
The utility model belongs to the field for gauge-thickness, is specifically related to a kind of quick testing agency for tundish bits.
Background technology
Tundish is the refractory material containers used in mini-mill steelmaking, first accepts to water from ladle the molten steel got off, and then is assigned in each crystallizer by middle water containing opening and goes.Continuous casting tundish has the effect storing molten steel and provide molten steel continuously to crystallizer.Along with the raising required steel quality, during storage molten steel, need add coverture at molten steel surface, carry out adiabatic heat-insulation prevent heat radiation to molten steel, isolated air, prevents molten steel oxidation simultaneously.Become bits after usual coverture fusing, according to the requirement of Ferrous Metallurgy, bits can not be greater than 40mm at the thickness of molten steel upper surface, when being greater than 40mm, can cause molten steel slag, pollute molten steel, therefore, bits must be discharged from slag-drip opening when being greater than 40mm.
In order to measure the thickness of bits, the method usually adopted inserts in molten steel with an oxygen lance, stops after 20-25 seconds, taken out by oxygen lance from molten steel, measure slag thick according to bits residual on oxygen lance.This kind of method Measuring Time is long, and operating environment is severe.
Utility model content
The purpose of this utility model is providing a kind of quick testing agency for tundish bits detecting bits thickness fast.
For achieving the above object, base case of the present utility model is as follows:
For the quick testing agency of tundish bits, comprise slide, bracing frame, test column, temperature sensor, controller and the gear matched, tooth bar, described pinion rotation is connected on sliding seat, tooth bar is slidably connected with slide on vertical, and sliding seat is marked with indicating graduation, tooth bar side indicates the graduation mark relative with indicating graduation, and support frame as described above is connected with tooth bar upper end, described test column upper end is connected with bracing frame, and described temperature sensor is detachably connected on test column lower end.
The principle of this programme and advantage: during detection, control gear rotates thus band carry-over bar moves down, bracing frame is connected with tooth bar upper end, so bracing frame moves down thereupon, the test column be simultaneously connected on bracing frame also moves down, because the temperature of bits is apparently higher than air themperature, the temperature of bits is starkly lower than the temperature of molten steel, so when the temperature sensor on test column enters bits, the temperature control that temperature sensor detects once obviously raises, when temperature sensor enters molten steel, the temperature that temperature sensor detects can second time obviously raise, obviously can obtain the data of twice temperature rising on the controller.In this programme, only obviously need be raised the distance of hour rack movement by record temperature sensor twice temperature, this distance is the thickness of bits, detected temperatures can be changed fast, thus can detect the bits thickness in tundish fast by temperature sensor.
Prioritization scheme 1, to the further optimization of base case, be also provided with servomotor, the output of this servomotor is connected with gear.Servomotor can realize position, the closed-loop control of speed and moment; Overcome the problem of step out of stepping motor, thus make the control of tooth bar shift position more accurate.
Prioritization scheme 2, to the further optimization of base case, any one of prioritization scheme 1, described test column epimere is provided with screw thread, and test column is threaded with bracing frame.Above-mentioned connected mode is simple, is convenient to installation and removal.
Prioritization scheme 3, to the further optimization of base case, any one of prioritization scheme 1, described tooth bar is provided with the through hole vertical with its length direction, and support frame as described above is plugged in this through hole.This connected mode is simple, is convenient to installation and removal.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model for the quick testing agency embodiment of tundish bits.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: slide 10, indicating graduation 11, bracing frame 20, test column 30, temperature sensor 40, controller 50, servomotor 60, gear 70, tooth bar 80, graduation mark 81, tundish 90.
Embodiment is substantially as shown in Figure 1: a kind of quick testing agency for tundish bits, comprise slide 10, bracing frame 20, test column 30, temperature sensor 40, controller 50, servomotor 60 and the gear 70 matched, tooth bar 80, tooth bar 80 is slidably connected with slide 10 on vertical, the output of servomotor 60 is connected with gear 70, servomotor 60 can realize position, the closed-loop control of speed and moment; Overcome the problem of step out of stepping motor, thus make the control of tooth bar 80 shift position more accurate.Sliding seat is marked with indicating graduation 11, and tooth bar 80 side indicates the graduation mark 81 relative with indicating graduation 11, and bracing frame 20 is connected with tooth bar 80 upper end, and wherein, tooth bar 80 is provided with the through hole vertical with its length direction, and bracing frame 20 is plugged in this through hole.This connected mode is simple, is convenient to installation and removal.Test column 30 upper end is connected with bracing frame 20, and test column 30 epimere is provided with screw thread, and test column 30 is threaded with bracing frame 20.Above-mentioned connected mode is simple, is convenient to installation and removal.Temperature sensor 40 is connected by screw in test column 30 lower end, and temperature sensor 40 is electrically connected with controller 50.
Specific works flow process:
As shown in Figure 1, during detection, the testing agency of this programme is placed on the side of tundish 90, start servomotor 60, servomotor 60 output driven gear 70 rotates, thus band carry-over bar 80 moves down, bracing frame 20 is connected with tooth bar 80 upper end, so bracing frame 20 moves down thereupon, the test column 30 be simultaneously connected on bracing frame 20 also moves down, temperature due to bits is starkly lower than the temperature of molten steel, so when the temperature sensor 40 on test column 30 enters bits, the temperature control that temperature sensor 40 detects once obviously raises, when temperature sensor 40 enters molten steel, the temperature that temperature sensor 40 detects can second time obviously raise, controller 50 can obviously obtain the data of twice temperature rising.Record temperature sensor 40 twice temperature obviously raises the distance of hour rack 80 movement, and this distance is the thickness of bits.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
