Description
Technical field
The invention belongs to make steel vacuum equipment field, and in particular to a kind of replaceable vacuum wear-resistant bend device.
Background technology
The quality and vacuum degree of smelting molten steel have substantial connection, and the good Molten Steel Cleanliness of vacuum degree is high.Therefore vacuum system pipe
Road cannot generate leakage, otherwise can not meet vacuum metling technological requirement.
The elbow of steel mill RH, VD, VOD ladle refining furnace vacuum pump system pump-line, elbow are adopted more both at home and abroad at present
After being crimped with steel plate together with pumping pipeline welding.Vacuum pump is designed as four or Pyatyi vapor injection system, at vacuum
Equipment is managed under the action of vacuum pump is persistently evacuated, is improved the jet velocity of working steam by the Laval nozzle of vacuum pump
To supersonic speed, using the pressure difference generated simultaneously, it is allowed to be mixed to form mixed gas with inhaling the high-temp waste gas at population, using expansion
Slow down after depressor throat and elbow is washed away after supercharging enters, final stage booster pump washes away cold into condenser after elbow with mixed gas
But in entire vacuum system, booster pump pipe diameter is big, height is high, and steam flow is big and high by pumping mixed gas temperature,
It is corrosive, granule foreign containing dust, elbow is most directly to be rushed by the sizable pressure of pumped gas in vacuum pipe at this time
Brush, elbow make elbow wash surface the more grind the more thin through erosive wear after a period of time, and it is worn out to eventually lead to elbow, vacuum pipe
Leakage is generated, vacuum treatment device exhaust capacity is caused to decline, required vacuum degree is not achieved.
Vacuum equipment administrative staff are made steel in usually plant maintenance, large-scale vacuum equipment is high across distance, height, because
It can not be checked inside this vacuum pipe head bending device, it is impossible to understand elbow abrasion condition, only generate external let out when elbow is worn
Leakage, just discovery elbow serious wear, such vacuum equipment cannot normal operation, influence rhythm of production.Need at this time to elbow into
Row repairing treatment repairs elbow by welding steel, and vacuum pipe elbow diameter is big, and repairing needs long time.Due to
Elbow is cambered surface, one block of steel plate cannot be used to weld, be repaired, must assure that after finally having repaired curved by two pieces of steel plate splicings
No leakage at head.It will result in this way using two pieces of steel plate splicings and form a weld seam in the middle, it is easy when vacuum equipment is run
Erosive wear simultaneously causes to leak.
Invention content
It conveniently checks elbow abrasion condition the purpose of the present invention is to provide a kind of and replaces in time, ensures vacuum system
The replaceable vacuum wear-resistant bend device of vacuum degree.
The technical solution adopted by the present invention to solve the technical problems is：A kind of replaceable vacuum wear-resistant bend device,
Including mounting flange pedestal, vacuum pipe, replaceable wear liner plate, flange, cylinder and fixed platform, the mounting flange pedestal leads to
The elbow part for crossing welding manner and vacuum pipe connects, and flange, the bottom of flange has been bolted on mounting flange pedestal
Portion is equipped with multiple dovetail grooves, and the top of replaceable wear liner plate is equipped with the boss being adapted with dovetail groove, flange by dovetail groove and
Boss is connect with replaceable wear liner plate, and the top of flange is equipped with lifting lug two, and lifting lug two is connect by cylinder stretch rod with cylinder, gas
The top of cylinder is fixed on by lifting lug one in fixed platform.
Specifically, fastening bolt holes are equipped on the flange and mounting flange pedestal, flange and mounting flange pedestal lead to
Bolts and nuts connection is crossed to fix.
Specifically, sealing ring is equipped between the flange and mounting flange pedestal, sealing ring there are twice.
Specifically, the bottom of the replaceable wear liner plate is the arc being adapted with vacuum pipe elbow part.
The invention has the advantages that：The vacuum wear-resistant bend unit protection vacuum pipe elbow of the present invention, resistance to punching
Brush, is convenient for changing, ensures the vacuum degree of vacuum system, can conveniently check elbow abrasion condition and replace in time, prevent vacuum
Elbow leaks, and provides safeguard for steel-making vacuum metling high quality fine work steel.
