Description

Technical Field

[0001] The utility model relates to the technical field of copper and copper alloy processing annealing, and specifically relates to a temperature measuring device for a bell-type annealing furnace. Background Art

[0002] The statements in this part are only to provide background information related to the technical solution of the present application to help understanding, and it does not necessarily constitute the prior art for the technical solution of the present application.

[0003] For the copper and copper alloy processing annealing process, the bell-type annealing furnace mainly changes the internal tissue structure of the metal by heating, heat preservation, and cooling operations on the rolled strip (coil) to obtain the required process performance and service performance. The annealing process is mainly obtained by calculating the mathematical model of the bell-type furnace control system. At present, there is no safe and reliable detection means to accurately detect and track the temperature change process of each point inside the annealing strip coil. Therefore, the mathematical model of the bell-type furnace control system cannot be corrected, and the uniformity of the bell-type furnace annealing cannot be guaranteed. Eventually, the performance of the annealed product cannot meet the requirements, resulting in a decrease in the product yield and an increase in production costs. Summary of the Utility Model

[0004] To solve the above problems, the present application provides a temperature measuring device for a bell-type annealing furnace, which includes: a furnace platform base, a pipe flange, two porous flanges, a sheathed thermocouple, a furnace platform flange, a gasket, and an O-ring. The furnace platform flange is connected to the exhaust gas discharge port on the furnace platform base, the pipe flange is connected to the exhaust gas pipe in the furnace platform base, the two porous flanges are respectively installed at the pipe flange and the furnace platform flange, and gaskets are arranged between the pipe flange and the porous flange and between the furnace platform flange and the porous flange to prevent air from entering the furnace platform interior. The pipe flange, the porous flanges, and the furnace platform flange have a plurality of reserved installation holes, and the sheathed thermocouple enters the furnace platform interior through the reserved installation holes, and an O-ring is arranged at each reserved installation hole.

[0005] In one embodiment, the furnace platform flange is welded to the exhaust gas discharge port on the furnace platform base.

[0006] In one embodiment, the pipe flange is fixedly connected to the exhaust gas pipe in the furnace platform base by bolts.

[0008] In one embodiment, each of the pipe flange, the porous flanges, and the furnace platform flange has nine reserved installation holes.

[0009] The beneficial effects of the present utility model include:

[0010] By installing a furnace flange at the exhaust port of the original furnace platform, the existing furnace platform structure is protected to the greatest extent, the possibility of protective gas leakage is reduced, and the possibility of additional protective gas leakage from the furnace platform is avoided, ensuring the smooth progress of production.

[0011] Measures such as installing gaskets at the joint surfaces of the porous flange, pipeline flange and furnace platform flange, and installing O-ring seals at the through-holes of the armored thermocouple on the flange are taken to minimize the risk of gas leakage from the flange surface.

[0012] By passing through the porous flange and its sealing surface twice, the risk of gas leakage is further reduced, the product yield is increased, and the smooth progress of production is facilitated.

[0013] The pipeline flange is completely matched with the original furnace platform flange, has good interchangeability, can be disassembled and installed on other furnace platforms for temperature measurement at any time, and saves production costs. BRIEF DESCRIPTION OF THE DRAWINGS
