Abstract
The utility model provides a thermal insulation device for blast furnace body welding in a low-temperature environment. The thermal insulation device can carry out heating and thermal insulation on a blast furnace body in the low-temperature environment so as to ensure that temperatures of a welding area can be above 0 DEG C. The thermal insulation device comprises a thermal shroud surrounding the blast furnace body and formed by thermal insulation boards, and steam outlet pipes communicated with a steam source are arranged in the thermal shroud.
Description
Technical field
The utility model relates to the attemperator of blast furnace welding under low temperature environment.
Background technology
In the winter of the Northwest, temperature is generally at-20 ℃ to-10 ℃.In order to weld blast furnace, must guarantee the welding region temperature more than 0 ℃, the guarantee welding quality under this low temperature environment.How the weld zone temperature being improved is a difficult point.
The utility model content
The purpose of this utility model is to provide and a kind ofly at low temperatures blast furnace is heated up, is incubated, to guarantee the attemperator of welding region temperature blast furnace welding under the low temperature environment more than 0 ℃.
The attemperator of blast furnace welding under low temperature environment of the present utility model comprises the surrounded heat shield with the thermal insulation board composition of blast furnace is arranged in the inside of heat shield the steam that communicates with vapour source and goes out pipe.
Above-mentioned attemperator is provided with fire retardant canvas at the inner surface of thermal insulation board.
Above-mentioned attemperator is provided with heat-preservation cotton between thermal insulation board and fire retardant canvas.
Above-mentioned attemperator, the periphery of blast furnace is provided with the multilayer platform, is provided with 4-10 steam and goes out pipe on the platform of every layer.
Above-mentioned attemperator all arranges the oxygen alarm on the platform of every layer.
The beneficial effects of the utility model: the utility model adopts thermal insulation board surrounded blast furnace, form an inner space isolated with external environment condition, simultaneously pass into high-temperature steam in this inner space, to improve temperature, make the temperature of the blast furnace of the needs welding in heat shield more than 0 ℃, just can guarantee welding quality when like this body of heater being welded.Fire retardant canvas has played the effect of anti-flaming thermal-insulation, has improved security and heat-insulating property.Heat-preservation cotton has further stoped scattering and disappearing of the interior heat of heat shield.The blast furnace periphery is provided with the multilayer platform, steam all is set on the platform of every layer pipe, has guaranteed the uniformity of blast furnace temperature on the differing heights of up and down.The oxygen alarm can be reported to the police when the oxygen content of setting, and has further guaranteed operating personnel's safety.
Description of drawings
Fig. 1 is the schematic diagram of the attemperator of blast furnace welding under low temperature environment.
Fig. 2 is the profile of heat shield 1.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
For blast furnace welds the attemperator that uses, comprise the surrounded heat shield 1 of blast furnace 5 under-20 ℃ of outside low temperature environments shown in Figure 1.Referring to Fig. 2, heat shield 1 is thermal insulation board 2, heat-preservation cotton 3, two-layer insulation canvas 4 from outside to inside successively.The periphery of blast furnace 5 is provided with multilayer platform 6 along the vertical direction, is provided with 8 steam and goes out pipe 7 on the platform of every layer, and steam goes out pipe 7 by main steam range 9 and vapour source.Oxygen alarm 8 all is set on the platform of every layer.Like this, go out pipe by steam and pass into high-temperature steam and heat, guaranteed that temperature in heat shield is more than 0 ℃.
Claims (2)
1. the attemperator that under low temperature environment, blast furnace welds is characterized in that: it comprises the surrounded heat shield with the thermal insulation board composition of blast furnace, the steam that communicates with vapour source is set in the inside of heat shield to manage.
2. attemperator as claimed in claim 1, it is characterized in that: the inner surface at thermal insulation board is provided with fire retardant canvas.
3. attemperator as claimed in claim 2, is characterized in that: be provided with heat-preservation cotton between thermal insulation board and fire retardant canvas.
