Technical field:
The utility model relates to composite plate and produces assembly, the particularly assembly of composite metal plate vacuum rolling method.
Background technology:
Composite metal plate refers to that different metal is combined into template, is meant that generally corrosion resistant plate is as compound as basal plate of coating steel plate and ordinary carbon steel.
Pressure vessel had both required inwall stainless, required to have certain wall thickness again, used all steel plate cost of manufacture high, had therefore proposed to use the requirement of stainless steel clad plate.Chinese patent 200510033870 " adopts compound base to produce the method for brazing hot rolled metal composite plate " and discloses a kind of technical scheme.This scheme is after two plied timber plates, two parent metal plates are stacked earlier, at the welded demarcation strip, implements the sealing welding of ring limit again, holes on peripheral soldering and sealing circle frame and vacuumize in the back, and packing is implemented hot rolling behind the aperture.
The assembly hierarchical structure is followed successively by before rolling: substrate, soldering flux layer, corrosion resistant plate, anti-high temperature antitack agent layer, corrosion resistant plate, soldering flux layer, substrate; Two involutory corrosion resistant plate surrounding point weld-ring week demarcation strips, encircle all demarcation strips and up and down two substrate lead angle grooves surround the ring week soldering and sealing formation soldering and sealing circle frame the space in.
The weak point that this production technology exists is: vacuumize and can not produce absolute vacuum; Still possess the minute quantity air between plate; Air can expand under hot-rolled state, and the air between two composite beds expands and can't run out so, and reason is that the surrounding has all sealed.This moment, air expanded, and can arrange antitack agent, destroyed the uniformity of antitack agent, thereby pit then occurred for a short time, the situation of composite bed bubbling then occurs greatly, or bonding point occurred.After treating that two composite layered plates separately, bubbling then forms depression, and the composite bed air spots is sliding, and composite bed thickness produces inhomogeneous point, influences board quality, outward appearance, does not meet the strict standard of pressure vessel with material.
Summary of the invention:
The purpose of the utility model is to overcome above-mentioned weak point, and a kind of assembly of composite metal plate vacuum rolling method is provided.
The scheme of the utility model is: hierarchical structure is followed successively by: substrate, soldering flux layer, corrosion resistant plate, anti-high temperature antitack agent layer, corrosion resistant plate, soldering flux layer, substrate; Encircle all demarcation strips and up and down two substrate lead angle grooves surround the ring week soldering and sealing formation soldering and sealing circle frame the space in; It is characterized in that: be welded with all seal weld seams of ring at the place, right angle, surrounding of every pair of substrate and corrosion resistant plate applying; Up and down two all seal welds seams of ring exterior point weld-ring week demarcation strips, substrate is provided with the hole, right angle, hole, right angle one stomidium mouth is on the binding face of relative corrosion resistant plate; Other end aperture, hole, right angle is on the side of substrate, and is fixed with seal plug at this stomidium mouth; The demarcation strip that soldering and sealing circle frame reaches with it pastes mutually is provided with several symmetrical air-vents.
The advantage of the utility model is: the preposition base material of going ahead of the rest is processed, is vacuumized, and then composite plate blanks forms and just can drill through pore, and residual air just can be run out of when rolling, thereby has guaranteed board quality.
Description of drawings:
Accompanying drawing is the utility model structural representation.
The specific embodiment:
The utility model hierarchical structure is followed successively by: substrate 2, soldering flux layer 3, corrosion resistant plate 1,4 layers of anti-high temperature antitack agents, corrosion resistant plate 1, soldering flux layer 3, substrate 2; Encircle all demarcation strip 5 and up and down two substrate 2 lead angle grooves surround the ring week soldering and sealing formation soldering and sealing circle frame 6 the space in; It is characterized in that: be welded with all seal weld seams of ring at the place, right angle, surrounding that every pair of substrate 2 and corrosion resistant plate 1 are fitted; Up and down two all seal welds seams of ring exterior point weld-ring week demarcation strips 5; Substrate 2 is provided with the hole, right angle; Hole, right angle one stomidium mouth is on the binding face of relative corrosion resistant plate 1, and other end aperture, hole, right angle is on the side of substrate 2, and is fixed with seal plug at this stomidium mouth; Soldering and sealing circle frame 6 reaches and is provided with several symmetrical air-vents with its demarcation strip that pastes mutually 5.
The steps include:
1. with pressure vessel with plate as substrate 2, all lead angle grooves of processing ring around substrate 2 single faces, corrosion resistant plate 1 peripheral size is less than all lead angle groove sizes of ring;
2. boring: between the adjacent two sides of the lead angle groove of substrate 2, drill through hole, a right angle, as vacuumizing the hole;
3. preposition butt welding: corrosion resistant plate 1 is tiled on this one side of substrate 2 lead angle grooves, and between tiling soldering flux layer 3, then on pressure platform, corrosion resistant plate 1 periphery encircles all seal weld with substrate 2 joint places and connects the preposition base material of formation;
4. vacuumize: vacuumize through hole, substrate 2 right angle, take out right angle, back port closing;
5. close base soldering and sealing: two preposition base material surface stainless steels are involutory; And 4 layers of the high temperature antitack agents of tiling between the two; Then at the demarcation strip 5 of two corrosion resistant plates, the 1 surrounding spot welding isoperimetric length of side; Implement submerged-arc welding soldering and sealing in trapezoid cross section, the four limits cavity that between two lead angle grooves, demarcation strip 5, forms again, form composite plate blanks;
6. boring: symmetry drills through several air-vents 7 on soldering and sealing circle frame 6 and demarcation strip 5;
7. hot rolling: composite plate blanks is preheated between 1000 °-1300 °, get into the hot mill rolling moulding;
8. cut edge and separate finishing completion product sheet material.
Owing to there is not absolute vacuum, especially vacuumize and be not in a container or a little volume, to vacuumize, vacuumize but put up between the plywood material slit, so vacuum is difficult to up to standard fully two.And at course of hot rolling, the high temperature of degree more than 1,000 will make the residual air rapid expanding, between two surface stainless steels, if residual air can't be run out, then push antitack agent 4, make it inhomogeneous, form depression or bubbling or bonding point in rolling back.And both are powerful separately the time, and defective just exposes out.Has residual air too between certain preposition base material, but do not exist both to separate, and interior shop is soldering flux that its requirement, effect are different fully with antitack agent 4, do not influence product quality.
