Description
Technical Field
The utility model relates to an electric stove temperature measurement technical field specifically is a copper alloy power frequency electric stove temperature measuring device.
Background
The traditional copper alloy power frequency electric furnace generally adopts the following two temperature measuring modes: (1) vertical immersion: a slide way is arranged at the upper part of the hearth, a floater is arranged at the lower part of the slide way, a thermocouple and a protection tube are fixed on the floater, the front end of the protection tube is immersed into the molten copper to a certain depth, and the thermocouple and the protection tube fluctuate along with the height change of the molten copper so as to monitor the temperature of the molten copper. The advantage of this mode is that the temperature measurement is accurate, overhauls the convenience. The disadvantage is that it is not practical in a smelting furnace for burning bulk materials and a holding furnace which must be frequently operated because the protective tube is easily broken and damaged during charging and stirring. Generally, the mode is more applied to the upward-drawing furnace, and other furnace types are rarely used basically. (2) Embedding: the thermocouple protection tube and the refractory castable are made into a prefabricated part, the protection tube is buried in the castable, the prefabricated part is arranged in a special refractory brick when an electric furnace is built, and the thermocouple is inserted into an inner hole of the protection tube for fixing. The advantage of this mode is that protection tube and copper liquid area of contact are few, and the protection tube is difficult to damage under the normal use condition, long service life. The temperature measurement is inaccurate, the temperature value is corrected and displayed according to the actual temperature difference, the sensitivity is low, and the temperature display has certain hysteresis. And the maintenance is inconvenient, and the furnace is stopped for maintenance after the copper liquid is poured to be dry. This approach is typically used with furnace types that require dumping, with other furnace types being rarely used.
At present, most of furnaces for producing zinc-copper-containing alloys at home and abroad adopt a visual inspection mode to judge the temperature, because the zinc-copper-containing alloys can be flaming when reaching a certain temperature, and the temperature can be judged to reach the peak value when the flaming is found, but a large amount of zinc smoke and slag are generated at the moment, thereby causing unnecessary waste. Although some copper alloys can meet the performance requirements only by flame-quenching refining, most furnace types, particularly under the condition of a smelting and heat-preserving furnace structure, the heat-preserving furnace is not required to be subjected to flame-quenching at all, and an effective temperature measuring device is required to meet the production requirements so as to control the production cost.
