Embodiment
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with accompanying drawing, the utility model is described in further detail:
The utility model provides for the protection of quickly cooling device in the isothermal annealed stove of rod iron steel pipe under atmosphere, described for the protection of quickly cooling device in the isothermal annealed stove of rod iron steel pipe under atmosphere mainly comprise removable top cover 1, upper bellows 3, upper spray nozzle plate 4, lower bellows 6, lower nozzle plate 7, spray cold house 8, interchanger 11, cold blast engine 12, recirculation blower 13, well heater 16, every curtain 15; When described for the protection of atmosphere under in the isothermal annealed stove of rod iron steel pipe during quickly cooling device maintenance, described removable top cover 1 can entirety take off; Described upper spray nozzle plate 4 is the base plate of bellows 3, and upper bellows 3 connect enterprising air port 2; Described lower nozzle plate 7 is the top board of lower bellows 6, and lower bellows 6 connect lower blast inlet 5; Shielding gas outlet 9 is positioned at the described bottom for the protection of the isothermal annealed stove quickly cooling device of rod iron steel pipe under atmosphere; Shielding gas outlet 9 connects circulating line 10; Circulating line 10 connects recirculation blower 13; Interchanger 11 is had between circulating line 10 and recirculation blower 13; Recirculation blower 13 exports and connects air supply duct 14; Air supply duct 14 connects enterprising air port 2 and lower blast inlet 5; Described well heater 16 is installed vertically on the both sides of bellows 3 and lower bellows 6, and is positioned at the described latter half for the protection of the isothermal annealed stove quickly cooling device of rod iron steel pipe under atmosphere; Described every curtain 15 be positioned at described for the protection of atmosphere under the rear ends of the isothermal annealed stove quickly cooling device of rod iron steel pipe, described have every curtain 15 automatically control elevating function.
The long and narrow space that described spray cold house 8 is formed between upper spray nozzle plate 4 and lower nozzle plate 7, to rod iron steel pipe about 19 rapid injection be carried on furnace roller 18 but.
Described recirculation blower 13 and cold blast engine 12 adopt variable frequency control, can control spray speed of cooling and temperature.
Thermopair 17, between enterprising air port 2 and lower blast inlet 5, sprays the temperature of cold house 8 with Controlling System joint detection; Described well heater 16 can participate in controlling according to the detected value of thermopair 17.
Described interchanger 11 is gas-to-gas heat exchanger.
The described working process for the protection of quickly cooling device in the isothermal annealed stove of rod iron steel pipe under atmosphere; see Fig. 1, Fig. 2, Fig. 3: the rod iron steel pipe 19 being heated to certain temperature by heat treatment furnace continues through with process speed described for the protection of quickly cooling device in the isothermal annealed stove of rod iron steel pipe under atmosphere, be positioned at the described impact effectively cutting off front and back stove section every curtain 15 for the protection of rod iron steel pipe isothermal annealed stove quickly cooling device rear ends under atmosphere.The shielding gas of certain temperature that what recirculation blower 13 provided have enters air supply duct 14, divides two-way to enter enterprising air port 2 and lower blast inlet 5 respectively in stokehold.Shielding gas through enterprising air port 2 enters upper bellows 3 and is dispensed to upper spray nozzle plate 4 and is sprayed by upper spray nozzle plate 4; shielding gas through lower blast inlet 5 enters lower bellows 6 and is dispensed to lower nozzle plate 7 and is sprayed by lower nozzle plate 7, and upper spray nozzle plate 4, lower nozzle plate 7 cool fast to the rod iron steel pipe 19 in spray cold house 8.Shielding gas after heat absorption arrives the described bottom for the protection of quickly cooling device in the isothermal annealed stove of rod iron steel pipe under atmosphere via spray both sides, cold house 8, exports 9 enter circulating line 10 by shielding gas.Shielding gas enters interchanger 11 through circulating line 10, and the freezing air that heat is supplied by cold blast engine 12 is taken away, and the shielding gas going out interchanger 11 sends into air supply duct 14 after recirculation blower 13 pressurizes.Now just complete an air cooling heat exchange process of refrigeration, the cycle operation then gone round and begun again.Recirculation blower 13 and cold blast engine 12 adopt variable frequency control, can control spray speed of cooling and temperature according to processing requirement.It is strict that rod iron steel pipe isothermal annealing sprays cold processing requirement; due to the reason of thermal inertia; often cooling rate is too fast at the described rear portion for the protection of quickly cooling device in the isothermal annealed stove of rod iron steel pipe under atmosphere, and now well heater 16 participates in controlling according to the detected value of thermopair 17.When spray cold house 8, rear portion cooling rate is too fast, and when the detected value of thermopair 17 is lower than set(ting)value, well heater 16 is devoted oneself to work and played concurrent heating effect, until thermopair 17 detected value meets range of set value.So far; describedly achieve a series of activities process such as gas injection cooling, gas-gas heat exchange refrigeration, well heater concurrent heating for the protection of quickly cooling device in the isothermal annealed stove of rod iron steel pipe under atmosphere, ensure that the thermal treatment of rod iron steel pipe isothermal annealing is carried out in strict accordance with technique.
The technical scheme provided from above the utility model, the utility model has following technique effect: (1) interchanger, recirculation blower are placed in outside refrigerating unit, and structure is simply convenient to safeguard; (2) gas-to-gas heat exchanger power regulation is level and smooth, stable; (3) well heater is placed in refrigerating unit, ensures that thermal treatment is strictly followed isothermal annealed processes curve and carried out.
The above is only preferred implementation of the present utility model; it should be pointed out that for the art those of ordinary skill, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
