Abstract
The utility model belongs to the improvement of wrapping mouth of a river negative pressure air extraction formula roaster structure in the middle of the steel mill continuous casting, a special wrap mouth of a river negative pressure air extraction formula roaster in middle of modified, the negative pressure air extraction pipe that the return bend of being bent by the right angle constitutes, the department of bending of its level pipe is setting up the inlet port, connect compressed air pipe on the inlet port, compressed air pipe's the axis and the dead in line of level pipe, set up a bowl form adapter sleeve on vertical pipe suitable for reading, bowl form adapter sleeve cooperatees with the middle shape of wrapping mouth of a river end opening. The utility model discloses it is rational in infrastructure, wrap the working procedure of toasting at the mouth of a river in the middle of can simplifying, easy operation, noise in the time of can reducing the field usage effectively reduces workman's intensity of labour.
Description
Technical field
This utility model belongs to the improvement of steel plant continuous casting tundish upper nozzle negative-pressure extraction type flushing roaster structure, the tundish upper nozzle negative-pressure extraction type flushing roaster of a kind of improvement.
Background technology
The Main Function of bleeder roaster be when continuous casting production toasts by tundish in hot-fluid introduce filling pipe end, filling pipe end is toasted, the temperature keeping tundish upper nozzle is consistent with tundish internal temperature, and raising continuous casting is opened and watered success rate.
Domestic each steel mill online negative-pressure extraction type flushing roaster use flow process is: middle hired car is opened to baking position, each stream uses the carriage suspension half intrusive mood mouth of a river, lifting is hired a car, it is suitable for reading that negative-pressure extraction type flushing roaster is inserted at the intrusive mood mouth of a river, use the exotic materials such as ceramic fiber cloth to seal and invade gap between the mouth of a river and roaster, press off stopper elevating mechanism, tundish is lighted a fire, open sucking type roaster compressed air, naked light suction, toast about 2-4 hour, tundish upper nozzle is baked to about 1100 DEG C, open and before watering, check tundish, close compressed air, close stopper, take off baking half intrusive mood mouth of a river bracket, rise tundish car, tundish car is opened to cast position.
The online negative-pressure extraction type flushing roaster of steel plant continuous casting system conventional is a fixed body.Being placed on baking of tundish position, each roaster spacing distance is fixed.
When the steel-making traditional online negative-pressure extraction type flushing roaster of factory director's continuous casting system uses, the subject matter existed is as follows:
1, during using, noise is big, does not meets national environmental protection regulation, worker's work under bad environment at the scene.I one weak worker of unit even produces occupation disease, causes tympanic member perforation.
2, the half intrusive mood mouth of a river must be used to be connected with bleeder roaster, the waste of resistance to material is serious.
3, traditional online negative-pressure extraction type flushing roaster weight is relatively big, and installation difficulty, worker's labor intensity is big.
Utility model content
The purpose of this utility model is to provide the tundish upper nozzle negative-pressure extraction type flushing roaster of a kind of improvement, it is rational in infrastructure, can simplify tundish upper nozzle baking working procedure, simple to operate, noise during onsite application can be reduced, effectively reduce the labor intensity of workman.
The purpose of this utility model is achieved in that the tundish upper nozzle negative-pressure extraction type flushing roaster of a kind of improvement, the negative pressure ventilation pipe being made up of the bend pipe of right-angle bending, the bending part of its horizontal tube arranges air inlet, air inlet is connected to compressed air hose, the axis of compressed air hose and the dead in line of horizontal tube, vertical tube suitable for reading on bowl-shape connection sleeve pipe is set, bowl-shape connection sleeve pipe closes with the matching form of tundish upper nozzle end opening.
It is as follows that this utility model mainly improves content:
1, make the sleeve pipe being connected with tundish upper nozzle, can directly connect with tundish upper nozzle during use, do not use the intrusive mood mouth of a river cut off to do middle connection.
2, by integrally-built optimization, alleviating the weight of negative-pressure extraction type flushing roaster, on-the-spot worker is easy for installation, alleviates eldest child's intensity.
Main improvement effect:
(1) simplify tundish upper nozzle baking working procedure, simple to operate, save baking of tundish time.
(2) noise during onsite application is reduced.
(3) due to weight saving more than 60%, effectively reduce the labor intensity of workman, greatly improve the working environment of workers.
This utility model is rational in infrastructure, simplify tundish upper nozzle baking working procedure, simple to operate, reduce noise during onsite application, effectively reduce the labor intensity of workman.
Accompanying drawing explanation
Being further described this utility model below in conjunction with accompanying drawing, Fig. 1 is this utility model sectional structure schematic diagram.
Detailed description of the invention
A kind of tundish upper nozzle negative-pressure extraction type flushing roaster of improvement, as shown in Figure 1, the negative pressure ventilation pipe being made up of the bend pipe of right-angle bending, the bending part of its horizontal tube 1 arranges air inlet, air inlet is connected to compressed air hose 3, the dead in line of the axis of compressed air hose 3 and horizontal tube 1, vertical tube 2 suitable for reading on bowl-shape connection sleeve pipe 5 is set, bowl-shape connection sleeve pipe 5 closes with the matching form of tundish upper nozzle end opening.It is respectively and fixedly connected with symmetrical level in the both sides of bowl-shape connection sleeve pipe 5 and fixes axle 4.The air inlet the inner connecting compressed air hose (3) at horizontal tube 1 bending part arranges cone undergauge spout 6.
Claims (1)
