The mechanism to control slag flow quantity for the size of the relative displacement of the top lower two blocks of perforate refractory brick of kind.
Slidingtype refractory brick slag notch shortcoming:
1st, slip refractory brick corrodes for a long time, washes away in slag liquid, temperature causes slag notch to expand under drastically changing, refractory brick cracking,
Fracture, service life is low.
2nd, upper and lower two pieces of slip refractory brick contact surface quality of fits are not high, and hardness is low, rub for a long time lower two blocks of refractory brick it
Between easily abrasion and gap occur, cause pulp water to reveal, easily cause industrial accident.
Content of the invention
The present invention is directed to the deficiencies in the prior art, there is provided a kind of intensity is high, the high rapid heat dissipation of thermal conductivity, and sliding contact surface is put down
Whole, fit clearance is good, and the metallurgical slag smelting furnace water-cooled of whole service life length is slided slag notch.
For realizing the object of the invention, there is provided technical scheme below：A kind of metallurgical slag smelting furnace water-cooled is slided and is slagged tap
Mouthful, including in the refractory masses in furnace shell, furnace shell, the fluid apertures prefabricated component of slagging tap being opened on furnace shell, fluid apertures of slagging tap prefabricated component
The heart offer slag tap fluid apertures it is characterised in that fluid apertures prefabricated component of slagging tap be embedded in a water-cooled slag tap set top groove in, No. one
Water-cooled set bottom of slagging tap is provided with corresponding No. two water-cooled slag sets, No. one, No. two water-cooleds set of slagging tap all include hollow base body, setting
In the centre bore of hollow base body, centre bore is coaxially corresponding with fluid apertures of slagging tap, and No. two water-cooleds are slagged tap and covered one end connection catch bar, push away
Lever connects oil cylinder carriage, and No. two water-cooleds set bottom of slagging tap is provided with disc spring holding device.
Preferably, fluid apertures prefabricated component material of slagging tap is fire-resistance rammed mass.
Preferably, water-cooled is slagged tap, set is cast in refractory masses.
Preferably, No. one, No. two water-cooleds set of slagging tap be water cooling casting red copper.
Preferably, disc spring holding device includes being installed on No. two water-cooleds and slagging tap covering the base plate of bottom, being provided with base plate
The lead of the heart, the standing screw being provided with lead both sides and pressing plate, pressing plate offers guiding corresponding with lead
Hole connecting hole corresponding with standing screw, lead is arranged with holddown spring, and lead passes through pilot hole, and standing screw is worn
Cross connecting hole and be provided with locking nut pressing plate is fixed and clamped on holddown spring.
Beneficial effect of the present invention：Present invention eliminates firebrick structure, using water cooling casting red copper structure, intensity is high, leads
The high rapid heat dissipation of heating rate, sliding contact surface adopts machine tooling flatness high, and fit clearance is good, and whole service life is long, through long
The situation that phase uses is seen and is solved that slidingtype refractory brick slag notch service life is low, quality of fit is not high, security reliability
The problem of difference.
