Description
Technical field
The utility model belongs to aluminum electrolysis industry, relates to a kind of resistance to galvanic corrosion and inhales aluminum pipe.
Background technology
In recent years, rapidly, electrolytic aluminum output hero occupies first place in the world China's aluminum i ndustry development, and aluminium production technology reaches in many aspects or close to advanced international standard, especially large prebaked cell for aluminum-reduction is widely applied, and the smelting level of aluminium has had large increase.Two-maing ladle is visual plant in Aluminum Electrolysis Production process, and it mainly carries the task of the sucking-off of high temperature aluminum liquid, transhipment from electrolyzer.And to inhale aluminum pipe be that all kinds are two-mand ladle (comprising uncovered two-maing ladle and vacuum ladle) indispensable important feature, it generally by being in bend pipe that topmost is connected with inclusion, insert horseshoe mouth straight tube in aluminium liquid when inhaling aluminium and two ends all form with the connection straight tube three sections of flange.All match with mother-son mouth between each section, and utilize bolt by Flange joint together.
During work, when inhaling aluminium in suction aluminum pipe horseshoe mouth straight tube insertion aluminium liquid, inhale the position being about 400mm at horseshoe mouth straight tube apart from port when aluminum pipe touches anode or when anode to pass through with regard to having high electric current, producing high heat makes cast iron local temperature raise, and its intensity is sharply declined and even local melting occurs.Because vacuum ladle utilizes siphon principle by aluminium water along inhaling in aluminum pipe suction two-mans ladle, two-man ladle when thus inhaling aluminium and inhale aluminum pipe inside and itself there is certain vacuum tightness, inhale aluminum pipe straight tube inwall to be easy to produce perforation under the effect of barometric point, aluminium liquid leaks from pit, causes and inhales aluminum pipe inefficacy.
Under existing physical condition, once inhale aluminum pipe to produce pit due to injury from electricity, after cisco unity malfunction, then entirety is scrapped, and needs the suction aluminum pipe more renewed.This method cost is high, not only causes the wasting of resources, and the new suction aluminum pipe changed still easily be electrically shocked cause inhale aluminum pipe again lost efficacy at short notice.
Utility model content
Technical problem to be solved in the utility model is to provide resistance to galvanic corrosion to inhale aluminum pipe.
The utility model finds a kind of patching material to inhale the seamless combination of aluminum pipe with perforation preferably, increases substantially the suction aluminum pipe work-ing life after repairing pit, easy to operate, quick, save time.
For reaching above object, the technical scheme that the utility model adopts is:
Aluminum pipe is inhaled in a kind of resistance to galvanic corrosion, comprise bend pipe, connect straight tube and horseshoe mouth straight tube, described horseshoe mouth straight tube has a perforation on the tube wall from most advanced and sophisticated 400mm place, and described perforation is embedded in refractory alloy disk, and described perforation and refractory alloy disk are perpendicular to the tube wall of horseshoe mouth straight tube.
Described horseshoe mouth straight tube can be original or used horseshoe mouth straight tube, is especially applicable to the horseshoe mouth straight tube of galvanic corrosion perforation.
The diameter of described perforation is 20mm.
Described refractory alloy disk is that siderochrome aluminium profiles electrical heating alloys turnery processing forms.Described siderochrome aluminium profiles electrical heating alloys is 12 ~ 30% containing the massfraction of chromium, and the massfraction containing aluminium is 4 ~ 8%, and model is as Cr17Al5, Cr25Al5, Cr28Al8Ti etc.
The thickness of described refractory alloy disk is suitable with the wall thickness of horseshoe mouth straight tube.
The utility model is especially applicable to repairing used perforation straight tube processing and obtaining.Specifically comprise the following steps:
1) cleaning of the instrument such as file, hand hammer is adopted to inhale aluminum pipe pit, then according to shape and the size of inhaling aluminum pipe electric shock pit, boring is adopted, the modes such as fraising and bore hole combination, be worked into unified for the electric shock pit inhaling aluminum pipe the hole that diameter is 20mm, and the surface in hole is without pounding trace.
2) dust at pit place is purged clean with pressurized air, dip in alcohol dampening pit place 2-3 time with hairbrush;
3) siderochrome aluminium profiles electrical heating alloys turnery processing Cheng Nengyu is inhaled the disk that aluminum pipe machining hole realizes combining closely.
4) suction aluminum pipe is heated to swelling state, adopt draw, press, the pushing of refractory alloy disk enters pit by the method such as top, disk need be coaxial with suction aluminum pipe pit, do not allowed any crooked situation.Inhale aluminum pipe cooling post shrinkage, fastening refractory alloy disk, pit place disk and suction aluminum pipe are in conjunction with closed seamless gap, and the suction aluminum pipe repaired can come into operation again.
When described suction aluminum pipe is heated to swelling state, temperature is 650 ~ 800 DEG C.
Described disk diameter is between 20.12 ~ 20.16mm.
Adopt structure of the present utility model, fill with the electric shock pit crossed and repair, the suction aluminum pipe of repairing not only can be come into operation again, and the more resistance to electric shock of pit mend, increase substantially the suction aluminum pipe work-ing life after repairing, there is economic benefit and the promotional value of highly significant.
The utility model has following beneficial effect:
1. adopt siderochrome aluminium profiles electrical heating alloys to repair and inhale aluminum pipe pit, because siderochrome aluminium profiles electrical heating alloys has good in oxidation resistance, resistivity high, in the aluminium water of 900 DEG C, corrosion resistance is strong, anodic breakdown is less likely to occur, greatly extends after repairing and inhale the aluminum pipe life-span.
2. siderochrome aluminium profiles electrical heating alloys disk is shrink-fit with inhaling aluminum pipe pit place, ensure that and can realize its Joint Properties good with inhaling aluminum pipe matrix normally inhaling aluminium work in 900 DEG C of aluminium water.
3. process the utility model equipment used simple, with low cost, aluminum pipe can be inhaled to perforation and carry out batch repairing.Siderochrome aluminium profiles disk adopts turning process to process, and does not need the equipment that smelting furnace etc. is large-scale.Siderochrome aluminium profiles electrical heating alloys low price, inhales aluminum pipe electric shock pit employing sectional repair method and substitutes the method in the past using whole new suction aluminum pipe instead, avoid causing the wasting of resources.In addition, suction aluminum pipe that size shape differs electric shock pit is all processed into the hole that diameter is 20mm, thus can batch machining production siderochrome aluminium profiles electrical heating alloys disk, then adopts that hot charge practice is unified repairs electric shock pit, single suction aluminum pipe renewal expense cost is low, simple to operate, safe and reliable.
