With the development of modern industry, more stringent requirements are proposed for quality of the user to steel, the hair of ladle refining techniques
Exhibition, has opened up the production technology of clean steel and ultra-clean steel, has promoted the development of metallurgical technology, domestic steel mill is in converter, electric arc
LF refining furnace is almost provided on stove.
Currently, the country, in steelmaking process, the dedusting method of LF stoves is that exhaust fume collecting hood side absorbs cigarette on stove, because chimney effect makes
Flue gas is upward, but has partial fume excessive from the electrode hole on petticoat pipe, causes partial fume that cannot effectively be siphoned away, causes to grasp
Make that environment dust concentration is exceeded, is degrading the work situation of operating personnel, pollutes the environment.
Invention content
Electrode hole flue gas anti-overflow device and its method, can keep away when it is an object of the present invention to provide one kind for the production of LF stoves
Exempt from flue gas to overflow from electrode hole, causes operating environment dust concentration exceeded, solve the problems, such as background technology.
The technical scheme is that：
One kind for LF stoves production when electrode hole flue gas anti-overflow device, comprising air hose, ceramic-seal ring, electrode hole, pneumatically
Stop valve and petticoat pipe, petticoat pipe are equipped with electrode hole, and electrode hole is set there are one ceramic-seal ring, the circumference side of the ceramic-seal ring
It is equipped with multiple fumaroles being evenly arranged upwards, ceramic-seal ring is connect with air hose, and air hose is equipped with pneumatic cut-off valve.
The jet direction of multiple fumaroles being evenly arranged on the ceramic-seal ring circumferencial direction is towards on the inside of petticoat pipe.
The air hose includes steel pipe one, metal hose and steel pipe two, and steel pipe two is fixed on petticoat pipe, one end of steel pipe two
It is connect with ceramic-seal ring, the other end of steel pipe two and one end of metal hose connect, the other end and the steel pipe one of metal hose
One end connection, the other end of steel pipe one connect with air source, and pneumatic cut-off valve is located on steel pipe one.
A method of electrode hole flue gas is excessive when for the production of LF stoves, is produced for LF stoves using defined by above-mentioned
When electrode hole flue gas anti-overflow device, comprise the steps of：
1. driving buggy ladle into LF stove working positions；
2. reducing petticoat pipe, petticoat pipe is made to cover on the ladle on buggy ladle；
3. electrode is dropped to from the electrode hole of petticoat pipe in the ladle on buggy ladle, pneumatic cut-off valve is opened simultaneously, air passes through
Air hose enters in ceramic-seal ring, and is sprayed by multiple fumaroles being evenly arranged on ceramic-seal ring circumferencial direction
Go out, flue gas block excessive at electrode hole is entered deduster, purification row by the air of ejection in petticoat pipe, and with wind turbine suction
It puts；
4. after refining, electrode being risen to working position, and buggy ladle is outputed working position, closing pneumatic cut-off valve.
The beneficial effects of the invention are as follows：Flue gas can be avoided to be overflowed from electrode hole, cause operating environment dust concentration super
Mark effectively improves the working environment at operation scene, considerably reduces the influence to operator's health.
