RH refining furnace is one of indispensable capital equipment of metallurgical industry, and vacuum tank is one of its important component, RH essence
Furnace uses vacuum tank circulation pipe, and partially leak air phenomenon during production and application, causes decarburization difficult, vacuum time prolongs
It is long, can be generated when serious alloy be not completely melt, circulating pipe scaling loss the phenomenon that, lead to casting wadding steel or stop pouring phenomenon, while is true
Empty slot is offline in advance, causes that the production cost increases.
Utility model content
To solve the above-mentioned problems, the purpose of the utility model is to provide a kind of circulating pipes for RH refining furnace vacuum tank
Gas leakage detection, cooling device, substantially reduce production cost.
In order to solve the above technical problems, the utility model adopts the following technical solution:
It is a kind of for the circulating pipe gas leakage detection of RH refining furnace vacuum tank, cooling device, including cylindrical distributor, it is described
Cylindrical distributor is hollow structure open at one end closed at one end, all side walls of the cylindrical distributor and 12 exhaust pipes
One end fixed connection respectively, the other end of 12 exhaust pipes is respectively used to and 12 supporting ring flow tube of vacuum tank corresponds
The open end of fixed connection, the cylindrical distributor connects compressed air source by air inlet pipeline, sets on the air inlet pipeline
It is equipped with compressed air valve.
Further, the other end of 12 exhaust pipes is respectively used to correspond with 12 supporting ring flow tube of vacuum tank and weld
It connects fixed connection or connection is detachably fixed by adapter.
Further, cylindrical distributor hollow structure closed at both ends, all side walls of the cylindrical distributor
Fixation is connected to respectively with one end of 12 exhaust pipes, is provided with compressed air inlet on all side walls of the cylindrical distributor.
Further, the exhaust pipe is welded and fixed with the cylindrical distributor.
Further, by the dismountable company of sealing of Threaded Connector Coupling between the exhaust pipe and the cylindrical distributor
It connects.
A kind of circulating pipe gas leakage detection, the monitoring of cooling device and cooling method method for RH refining furnace vacuum tank, it is special
Sign is, after including the following steps: that vacuum tank is built, connects various medium pipelines, while gas leak detection device being connected
On circulating pipe, before not toasted, the compressed air valve of the detection device is opened to the maximum, detects the position of circulating pipe gas leakage
It sets；After leak detection process, vacuum tank apparatus for baking is lighted into carry out off-line baking, while will hunt leak, the air inlet of cooling device
Compressed air valve on pipeline is opened, and valve opening is adjusted to 1/4-1/3 state, can carry out cooling work.
Compared with prior art, the advantageous effects of the utility model:
The operation of stopping leakage in the roof to vacuum tank circulation tracheae not only may be implemented by the structure design of the utility model, simultaneously also
After leak detection step can be implemented, when vacuum tank apparatus for baking is lighted progress off-line baking, while will leak detection, cooling device
Air inlet pipeline open, valve opening is adjusted to 1/4-1/3 state, at this point, the heat that baking generates is sealed in inside vacuum tank,
It avoids flame and returns out flame scaling loss circulation tracheae below dip pipe, reduce production cost.
