Abstract
The utility model provides a gunning machine for maintaining bottom grooves of circulation type vacuum degassing furnaces, which comprises a horizontally moving trolley, a water inlet tube, a water-material mixer, a spray gun, a spray gun nozzle, a lifter, a material inlet tube and a rotator. The gunning machine is characterized in that: the spray gun is 2500mm to 2900mm long, and the water-material mixer is positioned 200mm to 1300mm away from the peak of the lower end of the spray gun. The utility model has the advantages that: the utility model can maintain the circulating tube of the bottom groove of a circulation type vacuum degassing furnace on line, consequently, the bottom groove does not frequently get on and off line, the temperature loss of the vacuum chamber is little, and the bonding effect of gunning mix is good under the hot state. In practice, the average service life of the bottom groove is increased from 120 times to 281 times, the effect is remarkable, and the utility model can fully meet the actual requirement of the maintenance of the bottom groove of the circulation type vacuum degassing furnace.
Description
Technical field
The utility model belongs to technical field of ferrous metallurgy, is specifically related to a kind of spray repairing machine of safeguarding the vacuum degassing furnace base channel.
Background technology
As everyone knows, vacuum circulation degassing method is the method for a kind of vacuum processing of liquid steel of present widespread use.The main equipment of vacuum circulation degassing refining furnace is made up of vacuum chamber and air extractor, and wherein vacuum chamber partly comprises hot top cover, middle part, base channel and tubular stinger.Along with the raising of tubular stinger production technology and the improvement of in use toasting system, maintenance mode, production organization mode and manufacturing condition, the tubular stinger life-span has increased significantly.By contrast the life-span of furnace bottom groove generally on the low side, even groove occurs and be lower than the tubular stinger situation in age age, cause the maintenance of vacuum degassing furnace base channel frequent thus, very big to effective influence on system operation of vacuum degassing furnace.By the base channel that research is rolled off the production line and keeped in repair, find that most reasons seriously cause owing to base channel circulating pipe refractory brick corrodes.At present the method for head it off mainly concentrates on cold state and safeguards, but weak point is, because base channel needs to roll off the production line on frequent, the vacuum chamber temperature loss is big, and it is big to toast required energy consumption, and the base channel maintenance effects is also undesirable.
In order to address this problem, quote a kind of name of producing and be called closed tube (tubular stinger) spray repairing machine by smelting group in Beijing, constitute by parts such as translation chassis, water inlet pipe, water feed mixer, spray gun, lance head, lifting device, feed-pipe and swivel arrangements.This spray repairing machine is a specific equipment of safeguarding insert tube of vacuum degassing furnace under hot or cold conditions.Safeguard that the length of insert tube of vacuum degassing furnace spray repairing machine spray gun is 2400mm because the scene is used, the water feed mixer is in the position apart from endvertex 1400mm under the spray gun, and the height of lifting device is 3000mm.Still can not meet the demands fully if it is directly used in the maintenance of vacuum degassing furnace base channel, therefore must undergo technological transformation this spray repairing machine.
Summary of the invention
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, existing tubular stinger spray repairing machine is improved, satisfy the needs that the furnace bottom groove is safeguarded by length that increases spray gun and the position that changes the water feed mixer, thereby a kind of spray repairing machine of safeguarding the vacuum degassing furnace base channel is provided.Adopt this spray repairing machine can be implemented in on-line maintenance vacuum degassing furnace base channel under the hot state, series of technical such as solved fundamentally that the furnace bottom groove rolls off the production line on frequent, temperature loss is big, energy consumption is big and maintenance effects is bad, that guarantees to produce carries out smoothly.
The realization the technical solution of the utility model is:
A kind of spray repairing machine of safeguarding the vacuum degassing furnace base channel is to be made of translation chassis, water inlet pipe, water feed mixer, spray gun, lance head, lifting device, feed-pipe and swivel arrangement; Be characterized in that the length of spray gun is 2500～2900mm, endvertex 200～1300mm place under the spray gun, the position of water feed mixer.
The length of described spray gun is 2650mm, endvertex 900mm place under the spray gun, the position of water feed mixer.
The utility model has the advantages that it can carry out on-line maintenance in the circulating pipe position to the vacuum degassing furnace base channel under hot state, base channel rolls off the production line on need not frequently, and the vacuum chamber temperature loss is little, and the Gunning refractory bond effect is good under hot state.Facts have proved that furnace bottom groove mean life is brought up to 281 times by original 120 times, effect is very obvious, can satisfy the actual needs of producing fully.
Description of drawings
Accompanying drawing is the structural representation of the utility model spray repairing machine.
Among the figure: 1 translation chassis, 2 water inlet pipes, 3 water feed mixers, 4 spray guns, 5 lance heads, 6 lifting devices, 7 feed-pipes, 8 swivel arrangements.
Embodiment
Below in conjunction with the embodiment in the accompanying drawing the utility model is described in detail: the spray repairing machine of safeguarding the vacuum degassing furnace base channel is to be made of translation chassis 1, water inlet pipe 2, water feed mixer 3, spray gun 4, lance head 5, lifting device 6, feed-pipe 7, swivel arrangement 8.Wherein: the length of spray repairing machine spray gun 4 is 2650mm, and is corresponding with the furnace bottom degree of depth; The position of water feed mixer 3 is apart from 4 times endvertex 900mm of spray gun place, not scratching insert tube of vacuum degassing furnace lower end when guaranteeing that spray gun 4 carries out upkeep operation.
Concrete operation method is, mobile translation chassis 1, make and safeguard that vacuum degassing furnace base channel spray repairing machine is in the base channel below of on-line maintenance, promote spray gun 4 by lifting device 6, make lance head 5 arrive vacuum degassing furnace base channel circulating pipe place via the insert tube of vacuum degassing furnace inner chamber.Behind the Open valve, water passes through feed-pipe 7 by water inlet pipe 2, Gunning refractory under compressed-air actuated effect, after mixing by water feed mixer 3 again, be sprayed onto the circulating pipe place via spray gun 4 and lance head 5, pass through the whole circulating pipe inwall of swivel arrangement 8 rotary spray guns, 4 spray repairs refractory brick again, thereby realize online repairing and maintenance under the hot state of vacuum degassing furnace base channel.
