Description
Affiliated technical field
The utility model relates to a kind of steel industry that is used for molten steel, molten iron is carried out the device of thermometric, a kind of especially quick temperature measurement galvanic couple.
Background technology
China has molten steel, molten iron thermometric product now, mostly is to adopt thermocouple sensor.All used quick hardening cement to be product structure spare in its thermometric galvanic couple, the existing product running program is as follows: 1, hot junction welding, 2, wear quartz ampoule and compensating wire, 3, cold junction welding, 4, irritate the quick hardening cement slurry, 5, baking is dry, 6, detect 7, the assembling finished product, 8, the detection of dispatching from the factory.Quick hardening cement requires to function as follows in product: 1, can be effective prevention thermometric molten steel enter the rifle body, play protection temperature-measuring gun effect.2, resistance requires infinity therebetween, and making thermometric rectify negative pole can not have any path, otherwise thermometric does not go out or thermometric inaccurate.3, quick hardening cement does not burst below 1800 degree, otherwise the thermometric metal will rupture, can not displays temperature.4, heat transfer rate is slow, otherwise this product does not have protection well to measuring cold junction, and it is inaccurate to make product read temperature.5, play the effect of fixed support, compensating wire, measurement metal and quartz ampoule.Because of with the quick hardening cement be the thermometric galvanic couple of product structure spare to temperature and humidity requirement height, the South and the North can not use general formulation, thus quick hardening cement to prepare difficulty in process of production big, each producer's prescription also has nothing in common with each other, and has restricted this product of many manufacturer production.As shown in Figure 2, original thermometric galvanic couple comprises thermometric galvanic couple shell 7, be sleeved on the mud head 3 on galvanic couple shell 7 tops, the top of mud head 3 is provided with the quartz ampoule 6 that is used to install compensating wire, twine respectively on the compensating wire support 1 at the two ends of passing the compensating wire 2 of quartz ampoule 6, mud head 3 middle parts are provided with the cavity that is used for suit compensating wire support 1, compensating wire support 1 is packed into by the inner chamber of mud head 3 in the galvanic couple shell 7, outside quartz ampoule 6, be set with slag cap 5, be cast with quick hardening cement 8 between the inner chamber of compensating wire support 1 and galvanic couple shell 7 inner chambers and mud head 3, it is in manufacturing process, all need to irritate quick hardening cement slurry, it was both consuming time, complicated again to toast drying then.And the lower end of compensating wire 2 just rides against compensating wire support 1 in appearance, and it is easy to be drawn out of, thereby causes influencing commercial production.
Summary of the invention
The purpose of this utility model provides the quick temperature measurement galvanic couple that a kind of technology is simple, cost is lower, performance is better.
The technical scheme that its technical matters that solves the utility model adopts is: it comprises thermometric galvanic couple shell 7, is sleeved on the mud head 3 on galvanic couple shell 7 tops, the top of mud head 3 is provided with the quartz ampoule 6 that is used to install compensating wire, twine respectively on the compensating wire support 1 at the two ends of passing the compensating wire 2 of quartz ampoule 6, mud head 3 middle parts are provided with the cavity that is used for suit compensating wire support 1, compensating wire support 1 is packed into by the inner chamber of mud head 3 in the galvanic couple shell 7, is filled with rockwool blocks 4 in the inner chamber upper end of mud head 3.Be set with slag cap 5 outside quartz ampoule 6, the bottom at compensating wire support 1 is affiliated in the lower end bending of compensating wire 2.Between the inner chamber of compensating wire support 1 and galvanic couple shell 7 inner chambers and mud head 3, be filled with rockwool blocks 4.The inner chamber of mud head 3 upper end with it in cavity wall match to overlap and be equiped with quartz ampoule through hole rockwool blocks 4.The inner chamber of mud head 3 upper end with it in cavity wall match the rockwool blocks 4 of suit for being provided with the full circle plate-like rockwool blocks of quartz ampoule through hole or being that the semi arch rockwool blocks of 2 cooperations is combined into nahlock or being that the circular arc rockwool blocks of cooperation more than 2 is combined into nahlock.
The utility model has been compared following advantage with existing thermometric galvanic couple: the one, and manufacturing cost and cost of labor are cut down in a large number; The 2nd, manufacture difficulty is fallen at the end significantly; The 3rd, manufacturing time shortens in a large number, because of the utility model has been removed the oven dry cement time from; The 4th, the wet ability of moisture resistance is better than original product, because do not have any medium for air between its product both positive and negative polarity; The 5th, the temperature measurement accuracy of product is better than existing product, and it is slow than original product to draw the heat transfer rate of new product from the hot junction to cold junction through experiment, makes cold junction obtain better protection, and it is more accurate to cause product to read temperature; The 6th, this product vibration resistance is better than original product, because of the rigidity of rockwool blocks not as cement block; The 7th, this product helps measuring the recovery of metal.
