Abstract
The invention relates to an extruding container resistant to high temperature and high pressure, which is particularly used for extrusion process of thick-wall seamless steel pipes and belongs to the technical field of metal extrusion. The invention comprises an inside lining, a middle lining and an outer cylinder. The inside lining and the middle lining are positioned in the outer cylinder. The outer surface of the inside lining column is provided with a circular groove. A guard plate is laid in the groove and a thermal insulation ceramic layer is stuck to the guard plate. The outer surface of the outer cylinder column is provided with a circular groove and a steel wire wound layer is wound in the groove. The thermal insulation ceramic layer is added, thus avoiding the prestressed steel wire from relaxation due to heat. The steel wire is adopted to wind the prestressed extruding container, thus effectively improving the strength and rigidity of the extruding container. The prestressed wound extruding container is a novel combined extruding container. The steel wire prestressed extruding container has excellent performance over the combined extruding container, has high bearing capacity, long fatigue life, high strength and high reliability and can meet the use requirement for bearing high strength extrusion impact.
Description
One, technical field:
The present invention relates to a kind of extruding container resistant to high temperature and high pressure, specifically be used for the extrusion process of thick-walled seamless steel pipes, belong to technical field of metal extrusion.
Two, background technology:
Recipient is the crucial frock of metal extruding, and its effect is to hold blank, bears axial force and radial load that pinch shock causes simultaneously.In the extrusion process, recipient is bearing the associating destruction of high temperature, wearing and tearing and stress.The conventional recipient of tradition often adopts multi-layer compound structure at present, and the overcoat of recipient and liner adopt the hot charging stationary fit, apply certain tangential compression prestress to liner, to improve the intensity of recipient, improves the liner bearing capacity.But large-scale recipient for external diameter 〉=3600mm, internal diameter 〉=700mm, adopt conventional multi-layer compound structure and hot charging manufacturing, no matter technical still all have huge difficulty economically, be not easy to realize, in addition, whole major diameter heavy casting and forging, cost height not only, the interior tissue poor performance, the capability and performance instability can not satisfy the instructions for use of bearing the high strength pinch shock.
The recipient long-term work after steel wire is heated and relaxes, badly influences the intensity and the fatigue life of recipient in hot environment more than 1000 ℃, do not possess higher heat resistance, and effect of heat insulation is undesirable.
Three, summary of the invention:
The object of the present invention is to provide a kind of extruding container resistant to high temperature and high pressure of high temperature resistant, high pressure resistant, long service life.
Technical solution: the present invention includes: liner, middle lining, urceolus, liner, middle lining are housed in the urceolus, middle lining cylindrical outer surface is driven cannelure, be equipped with backplate in the groove, paste the thermal insulation ceramics layer on the backplate, the urceolus cylindrical outer surface has cannelure, is tied with the steel wire winding layer in the groove.
Urceolus is spliced by four shapes and all identical quadrant arc monomer of size.
On the sidewall of monomer alignment pin is housed, is connected to the full circle urceolus by alignment pin between monomer, outer tube outer surface has cannelure, is provided with backplate at the bottom of the stainless steel in the groove, is tied with the steel wire winding layer on the backplate at the bottom of the stainless steel in the groove.
The steel wire winding layer is provided with anti-corrosion material.
Anti-corrosion material is antirust paint, glass wool cloth and epoxy resin.
Outer casing is coated on the anti-corrosion material and with urceolus and welds.
Urceolus is the split steel-casting.
Urceolus is spliced by four shapes and all identical quadrant arc monomer steel-casting of size.Change the small-sized foundry goods splicing of split into by traditional urceolus solid forging, monomer steel-casting specification diminishes, and casting, mechanical processing technique are simplified, production cost reduces greatly, shorten the production cycle, and small-sized foundry goods interior tissue grain size is even, stable mechanical property, quality assurance, convenient transportation.
The present invention adds one deck thermal insulation ceramics layer owing between middle lining and urceolus, and is lax to avoid compressor wire to be heated.The thermal insulation ceramics material of selecting for use has higher heat resistance, can satisfy and use in 1100 ℃ hot environment for a long time, also has excellent heat-insulating property in wide temperature range.
By actual tests, under normal production conditions, extraneous air free convection, ceramic layer thickness is 7mm, under 5 minutes or the 10 minutes situations, detected temperatures, steel billet also can not pass to the recipient urceolus to the heat affected area of mould, therefore to not influence of winding steel wire; 300 ℃ of liner preheatings, and through the endless time, the recipient temperature during ceramic layer 7mm is respectively about 70 ℃; When the liner operating temperature was 1000 ℃ of left and right sides, after 3 hours, the outer recipient urceolus temperature of ceramic layer was about 170 ℃.This is a test value under special circumstances, and temperature environment is so not abominable during ordinary production.
Another one advantage of the present invention is to adopt steel wire to twine the prestressing force recipient, can effectively improve intensity, the rigidity of recipient, it is a kind of novel combination recipient that prestressing force twines recipient, steel wire prestressing force recipient has the performance more more superior than combination recipient, have high bearing capacity, high fatigue life, high intensity and high reliability, can satisfy the instructions for use of bearing the high strength pinch shock.
