Abstract

The utility model discloses a furnace door water-cooled end wall of a roller hearth soaking furnace. The furnace door water-cooled end wall comprises an end wall body, wherein the top part of the end wall body is connected with a furnace top, the bottom part of the end wall body is connected with the furnace door, a water-cooled pipe is arranged in the end wall body, and an anchoring element is connected at the periphery of the water-cooled pipe and cast into a whole with a wall surface plate of the end wall body through a fire-proof material layer. By adopting the water-cooled end wall structure, the damage caused by the high-temperature burning of flame and hot gas overflow from the opened furnace door is avoided, therefore a furnace door end wall, a steel structure, and auxiliary equipment of a track are protected, and the normal opening/closing action of the furnace door during the producing process is ensured; the failure rate of the furnace door is reduced, and the number of whole line casting-breaking is reduced; the application rate of the furnace door function is guaranteed, and technological requirements as furnace pressure and furnace temperature during the normal producing process are ensured; the cost is low; the replacing number of furnace body is reduced, and resource waste is avoided; and the time for repairing or replacing the end wall structure is shortened.

Description

Roller-bottom type soaking pit fire door water-cooled headwall
Technical field
The utility model relates to the heating furnace wall body structure, refers to a kind of roller-bottom type soaking pit fire door water-cooled headwall particularly.
Background technology
The roller-bottom type soaking pit except guaranteeing that slab reaches the rolling mill practice target, also plays the important function of regulating full factory rhythm of production in the continuous casting and rolling process.Roller-bottom type soaking pit burner hearth is narrow and grow, and the soaking pit fire door is very big to the control influence of furnace pressure, furnace temperature, and therefore, soaking pit fire door fault rate is than the normal reheating furnace height.
Soaking pit fire door top headwall is the metal structure panel, directly waters the material feeding cast with heavy behind the weld anchor firmware.During stove door switch, flame or hot gas overflow and cause the metal decking distortion, and it is serious that doorframe is subjected to high temperature sintering.Cause the anchoring piece and the refractory material that are welded on the panel to come off behind the panel deformation, thereby lose insulation effect, make the distortion of steel constructions such as fire door doorframe, track, fire door can't move, and causes disconnected watering completely very easily.If the anti-material of fire door headwall collapses, the replacement cost height, need 20 hours repair time.
Summary of the invention
The purpose of this utility model will provide a kind of roller-bottom type soaking pit fire door water-cooled headwall exactly, and is stuck because of the fire door that reasons such as the distortion of fire door headwall steel construction, anti-material come off cause in production process in order to solve fire door, problem that can't regular event.
For achieving the above object, the designed roller-bottom type soaking pit of the utility model fire door water-cooled headwall, the headwall top is connected with furnace roof, bottom and fire door join, and is provided with water cooling tube in the described headwall, described water cooling tube periphery is fixed with anchoring piece, and the wallboard by refractory masses and headwall is cast in one.
Preferably, the two ends at described wallboard top are provided with hanger, make things convenient for the installation of roller-bottom type soaking pit fire door water-cooled headwall, change the time thereby shorten the fire door headwall, can guarantee that not blowing out is changed in normal maintenance process.
The beneficial effects of the utility model:
1. water-cooled headwall structure has solved flame when door opened, hot gas overflows the high temperature sintering that causes and damages, and has protected the auxiliary device of fire door headwall, steel construction, track, guarantees that the stove door switch action is normal in the production process;
2. reduce the fire door fault rate, reduced the disconnected number of times that waters completely; The cancellation metal decking prevents that anchoring piece from coming off because of the metal decking distortion, thereby causes anti-material to come off;
3. guarantee the fire door function rate that comes into operation, guaranteed technological requirements such as the furnace pressure in the normal productive process, furnace temperature;
4. utilize heat resisting steel water cooling tube weld anchor firmware, the pattern of pouring into a mould again replaces old fire door headwall structure, and cost is low;
5. reduce fire door and change number of times, prevent the wasting of resources;
6. new fire door headwall structure repair or replacing can be finished in 10 hours.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of roller-bottom type soaking pit fire door water-cooled headwall.
Fig. 2 is the side-looking structural representation of roller-bottom type soaking pit fire door water-cooled headwall.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Roller-bottom type soaking pit fire door water-cooled headwall shown in the figure, comprise headwall body 1, the top of headwall body 1 is connected with furnace roof, the bottom and the fire door of headwall body 1 join, be provided with water cooling tube 2 in the headwall body 1, water cooling tube 2 peripheries are connected with anchoring piece 3, and anchoring piece 3 pours into an integrated entity by the shingle nail 5 of refractory masses 4 with headwall body 1.The two ends, top of shingle nail 5 are provided with hanger 6.
The water cooling tube 2 that makes is fixedly mounted on the shingle nail 5 of headwall body 1, again at water cooling tube 2 peripheral solder anchoring pieces 3, carry out refractory masses 4 cast then, with water cooling tube 2 parcels wherein, roller-bottom type soaking pit fire door water-cooled headwall is installed on the fire door by hanger 6.
Feed water-cooled in the production process, guarantee that the water-cooled headwall is not damaged under high-temperature condition, thus other steel constructions such as protection fire door column, track.

Claims (2)
