Abstract
The utility model relates to a temperature measuring device for a cover type annealing furnace, which comprises a furnace stage for accommodating annealed metal material, an inner cover, a heating cover and a cooling cover. The temperature measuring device is characterized in that two independent thermocouples for measuring furnace temperature are arranged on the furnace stage. According to the utility model, the two independent thermocouples are arranged on the furnace stage so that the annealing furnace has two temperature measuring points, thereby improving measurement precision, effectively avoiding that the thermocouple has to be replaced when the furnace is flamed out or maintained if there is only one thermocouple, ensuring continuity of annealing process, completely avoiding output and quality loss caused by thermocouple damage, and improving working efficiency and product quality.
Description
Technical field
The utility model relates to a kind of metal heat treatmet equipment, relates in particular to a kind of bell type annealing furnace temperature measuring equipment.
Background technology
Every bell type annealing furnace is made up of a table, an inner cover, a heating mantles and a cooling dome.The bell type annealing furnace annealing process is divided into heating period and cooling stage.Heating period is positioned over coil of strip on the table, with inner cover coil of strip is covered on the table then, with heating mantles inner cover and table and coil of strip is covered and heats.Cooling stage hangs away heating mantles, with cooling dome inner cover and table and coil of strip is covered and cools off.The purpose that metal material is annealed in bell furnace is for softening tissue and solid solution carbonide, so that the rolling or payment user use of operation down.The effect of cover annealing depends on the anneal height of soaking temperature and the length of temperature retention time, and the control of annealing temperature is all the most key to the security of belt steel product quality and bell type annealing furnace itself.Existing bell type annealing furnace Control for Kiln Temperature all is to realize by a thermopair of installing on the table.Because the Control for Kiln Temperature thermopair has only a temperature survey point, when this thermopair occurs damaging in the use, because thermopair is contained on the table, and table also is covered with inner cover and heating mantles or cooling dome outward, can not change the thermopair that damages in process of production, just can change processing after having only the cooling of blowing out by the time and hanging away inner cover and heating mantles, increase fault handling time, reduce production efficiency, wasted the production energy.Secondly, even if thermopair does not damage, also there is the possibility that precision lost efficacy and temperature survey is inaccurate.Owing to have only a thermopair, there is not the thermopair under the same measuring condition to compare reference, can't judge whether that precision lost efficacy and temperature survey is inaccurate, production quality control is brought very big hidden danger.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of measuring accuracy controlled bell type annealing furnace temperature measuring equipment at the above-mentioned state of the art, by two thermopairs that can automatically switch are set, the steady and continuous that has guaranteed production is carried out, and has improved production efficiency and product quality.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of bell type annealing furnace temperature measuring equipment, comprise table, inner cover, heating mantles and the cooling dome of the metal material that is used to place annealing, it is characterized in that: described table is provided with two thermopairs that independently are used to measure furnace temperature.
As improvement, described table is xsect for circular boss shape structure, is provided with two mounting holes that are used to install thermopair on the step surface of boss shape structure, and described thermopair is inserted into respectively in the corresponding mounting hole.
At last, described mounting hole is the diagonal angle distribution corresponding to the center of circle of described table, and described thermopair is symmetricly set on the step surface of table.
Compared with prior art, advantage of the present utility model is: by two independently thermopairs are set on table, make annealing furnace that two points for measuring temperature be arranged, not only improved measuring accuracy, when also effectively having avoided having only single thermopair, thermopair has damaged in the time of must waiting until the flame-out or maintenance of stove and could change, has guaranteed the continuity of annealing process, has stopped to cause output and mass loss because of the thermopair damage.The utility model is reasonable in design, has guaranteed that the steady and continuous of production is carried out, and has improved production efficiency and product quality greatly.

Fig. 2 is the vertical view of Fig. 1.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, a kind of bell type annealing furnace temperature measuring equipment, the table 1 that comprises the coil of strip 2 that is used to place annealing, be nested with the inner cover 3 on table, heating mantles 4, cooling dome and two thermopairs 5 and 6 that independently are used to measure furnace temperature, table 1 is xsect and is circular boss shape structure, coil of strip 2 places the top, middle part of table 1, on the step surface of the boss shape structure of table 1, be the diagonal angle and be provided with two mounting holes 11 that are used to install thermopair 5 and 6 corresponding to the center of circle of table 1, thermopair 5 and 6 is inserted into respectively in the corresponding mounting hole 11, be symmetricly set on the step surface of table 1, making like this has two measurement of furnace temperature points on the table 1, one of them is the control thermopair, one is standby point for measuring temperature, if wherein a thermopair 5 damages, so just can enable another thermopair 6 at once, when so just having avoided having only single thermopair, thermopair has damaged in the time of must waiting until the flame-out or maintenance of stove and could change, guaranteed the continuity of annealing process, stopped to cause output and mass loss, improved work efficiency because thermopair damages.In addition, two temperature survey points are arranged in the table 1, two thermopairs 5 and 6 all can be measured furnace temperature, because two thermopairs 5 are identical with 6 measuring conditions, if the furnace temperature deviation of the two measurement is excessive,, the possibility that thermopair 5 and 6 precision lost efficacy and temperature survey is inaccurate is arranged then as surpassing 20 ℃, then can when stove stops working or overhaul, proofread and correct the hidden danger of avoiding thermopair 5 and 6 precision to lose efficacy and bring to production quality control to thermopair 5 and 6.
Two thermopairs 5 in the present embodiment and 6 are for being symmetrically distributed, and reduce the foreign object risk of damage simultaneously of falling.Also can adjust both positions according to the equipment actual conditions, as long as two thermopairs 5 and 6 are independently of one another, spaced apart getting final product.
