Description
Technical field
The present invention relates to a kind of production method of laminated metallic compound roll bending, belong to layered metal composite technical field.
Background technology
Method hot rolling is the common method manufacturing layered metal composite, is allow the metal of two kinds of clean surface contact with each other, and reaches the complex method of continuous print metallurgical binding by high diffusion effect between atom when heating and plastic deformation.The base step of high rolling composite blank generally comprises: the polishing of basic unit, cladding substrate faying face, substrate, compound plate superimposed, surrounding seam subsequently, port openings and install blast pipe, sealed after being vacuumized.But, in the industrial production, in high rolling composite blank, there is a small amount of gas residue unavoidably, when these gases heat in airtight slab, meeting expanded by heating, causes composite billet bubbling, slab deformation, cause weld cracking time serious, slab is scrapped, or causes the damage of rolling equipment.For method hot rolling, effectively can discharge the residual gas in slab in heating and the operation of rolling, be ensure that composite billet rolling is successfully crucial.
Prior art " method of vacuum assembly-antivacuum rolling layered metal composite roll bending " (ZL201210531128.1), by spaced openings on the tail end of composite billet, the hollow pipeline section of aluminium matter is inserted in each hole, the inner of the hollow pipeline section of aluminium matter is made to be placed in the rolling wider space of the ducted body of composite billet, and outer end passing hole being connected with vavuum pump by pipeline, seal between Kong Yuguan.Composite billet is in heating furnace during conventional heating, along with base temperature rise to higher than aluminium matter hollow pipe fusing point time, the hollow pipeline section fusing of aluminium matter, perforate is opened wide, with head end front, the posterior position of tail end, when feeding conventional rolling mill is rolled, the inner remaining air of composite plate blanks, can discharge by the steam vent opened wide from its tail end in rolling roller compaction process, namely obtains layered metal composite coiled sheet.
But, also there is following two problems in above-mentioned technical scheme: one is, when sealing between the hole of aluminium matter hollow pipe and base termination, for making it firmly bonding, be not ejected under vacuumized conditions, adopt the method for welding, but because aluminium matter hollow pipe is non-ferrous metal, hole is ferrous metal, there is the problem of welding difficulty between dissimilar metal, use special welding rod, cost is very high.Two are, the inner of the hollow pipeline section of aluminium matter arranged is placed in the rolling wider space of the ducted body of composite billet, in composite billet heating process, along with base temperature rise to higher than aluminium matter hollow pipe fusing point time, the hollow pipeline section fusing of aluminium matter, composite billet internal contamination composite billet can be fused into after aluminium matter hollow tubular portion fractional melting in wider space, adverse effect is brought to the quality of composite billet.
Summary of the invention
Existing problem being set in order to solve the blast pipe of high rolling composite blank in prior art, the invention provides a kind of production method of laminated metallic compound roll bending.
The present invention is realized by following technical proposal: a kind of production method of laminated metallic compound roll bending, it is characterized in that through following each step:
(1) prepare the bend pipe of ferrule: polished by the mouth of pipe of high-melting-point material hollow pipe, and inside pipe wall is mechanically cleared up to cleaning, then high-melting-point material hollow pipe is fixed in the horizontal plane; Low-melting-point metal or the alloy of liquid will be melted into, slowly import from one end of high-melting-point material hollow pipe, low-melting-point metal or alloy fluid are freezed in this end and forms shutoff plug, controlling this envelope stemming length is 5 ~ 30mm, after being cooled to room temperature, high-melting-point material hollow pipe is bent to 10 ~ 90 °, obtains the bend pipe of mouth of pipe shutoff;
(2) composite plate blanks: plied timber material and parent metal material are carried out surface treatment with conventional mechanical methods respectively clean to combination interface, by stacked for two blocks of plied timber materials, and isolated material is added in the middle of stacked two blocks of plied timber materials, be put in afterwards, go to a grassroots level between metal material, to upper, the surrounding of metal material of going to a grassroots level carries out welding formation four sidewalls, and make the surrounding of plied timber material wherein reserve rolling extension space, obtain composite billet, and hole is opened on the head end and tail end sidewall of composite billet, high-melting-point material hollow straight pipe is inserted in the through hole of head end sidewall, the inner of high-melting-point material hollow straight pipe is communicated with rolling extension space, and outer end is connected with vavuum pump, the straight tube end of inserting step (1) gained bend pipe in the through hole of tail end sidewall, and communicate with rolling extension space, and the bend pipe of mouth of pipe shutoff is outside, and elbow is down, the sweep of this bend pipe and the angle of composite billet tail end sidewall are 90 ~ 170 °,
(3) vacuumize: by the high-melting-point material hollow straight pipe of step (2) ,-1 × 10 are evacuated to composite plate blanks inside
-2~-1 × 10
-3pa, and pressurize is after 2 ~ 3 hours, the external port of shutoff high-melting-point material hollow straight pipe, obtains vacuum composite plate base;
(4) rolling: step (3) gained vacuum composite plate base is sent in hot-rolling heating furnace, carry out conventional heating, when composite billet is heated to the fusion temperature of low-melting-point metal or alloy in stove, low-melting-point metal or alloy melting also flow out along decurved elbow port, make the port no longer shutoff of bend pipe, afterwards with head end front, the posterior position of tail end, send on conventional rolling mill and be rolled, because the elbow port of composite billet tail end is opened, thus in rolling roller compaction process, enable residual gas in base discharge from the elbow port of opening, finally obtain laminated metallic compound roll bending.
The high-melting-point material hollow pipe of described step (1) and (2) refers to that the material of this hollow pipe and composite billet parent metal material have good welds, and the maximum heating temperature of its fusing point when heating higher than composite plate blanks rolling, ensure that high-melting-point material hollow pipe is not melted in composite plate blanks heating rolling process, this high-melting-point material is irony, SUS201 material or SUS304.
The length of the high-melting-point material hollow pipe of described step (1) and (2) is 150 ~ 300mm, and bore is 10 ~ 25mm.
The low-melting-point metal of described step (1) or alloy are zinc, tin, aluminium, terne metal (plumbous 38.14%, tin 61.86%), red brass (tin 91%, zinc 9%) or bismuth alloy (bismuth 58%, tin 42%).
The parent metal material of described step (2) is carbon steel or steel alloy.
