Description
Technical field
The invention belongs to cooker and make the field, relate to a kind of aluminium alloy compression casting pan with compound bottom and combination process thereof.
Background technology
At present, the compound base pressure skillet that can be used for electromagnetic oven mostly is mechanical riveted formula composite bottom boiler, and this composite bottom boiler is to adopt the riveted nail that the stainless iron compound bottom sheet is fixed on bottom of pot body, owing on the stainless iron compound bottom sheet riveted through hole is arranged, the effective area that can produce eddy current on the compound bottom sheet is less, so the thermal efficiency is lower; And exist mould and parts to make defectives such as complexity, pot body and egative film bonding strength difference; And the out-of-flatness of stainless iron compound bottom sheet, the long-term use also can be caused damage to the electromagnetic oven surface.In addition, also having some compound base pressure skillets then is pre-processed syndeton on the stainless iron egative film, be cast into one by syndeton and pot body during die casting, though can solve deficiencies such as the thermal efficiency is low, the egative film flatness is not enough preferably, still exist mould and parts to make complicated, shortcomings such as difficulty of processing is big, bonding strength difference; Especially compound bottom sheet reliability of positioning in compression mod is poor when die casting, can cause the waster rate higher, furthermore die casting compound tense energy consumption height, so production cost is wayward.
Summary of the invention
At the problems referred to above, the purpose of this invention is to provide a kind of reliable, the thermal efficiency is high, the heat-resistant anti-fatigue performance is stable aluminium alloy compression casting pan with compound bottom simple in structure, compound.
The objective of the invention is to realize as follows: a kind of aluminium alloy compression casting pan with compound bottom, comprise aluminium alloy compression casting pan pot body, stainless iron compound bottom sheet, be characterized in the direct and smooth compound one that is of bottom of pot body of stainless iron compound bottom sheet.
To achieve these goals, and control production cost, simplification production technology effectively, the present invention also provides a kind of combination process of aluminium alloy compression casting pan with compound bottom, and this combination process may further comprise the steps:
(1) die casting: with aluminium alloy compression casting pan pot body die cast on die casting machine;
(2) cleaning surfaces: cleaning is carried out in the pot surface;
(3) coating complexing agent: at the one side coating complexing agent of stainless iron compound bottom sheet;
(4) paster: with the left-hand thread placement up of aluminium alloy compression casting pan bottom of pot body, the one side that will scribble the stainless iron compound bottom sheet of complexing agent again is attached on the bottom of pot body;
(5) precompressed: on compounding machine, the stainless iron compound bottom sheet is pressed on the bottom of a pan, and makes the compaction pressure value remain on 20～100bar;
(6) compound: as on the compounding machine induction coil, to be 5KHz～6.5KHz by frequency, size is the alternating current of 100～150A, the stainless iron compound bottom sheet produces induced-current in the alternating magnetic field that induction coil forms like this, induced-current causes being rapidly heated after the heating of stainless iron compound bottom sheet, make aluminium alloy compression casting pan bottom of pot body temperature rise to 450～630 ℃, duration is 40～45s, with the complexing agent is intermediate medium, make the stainless iron compound bottom sheet be compounded in the bottom of aluminium alloy compression casting pan pot body, in the recombination process, the compaction pressure value is remained on 20～100bar;
(7) pressurize cooling: after the bottom of a pan was compound, compounding machine kept the pressure of 20～120bar, and the duration is 20～60s;
(8) surperficial subsequent treatment: after treating the compression casting pan cooling, remove the overlap on the pot body, carry out subsequent treatment such as sandblast, spraying again, can make aluminium alloy compression casting pan with compound bottom.
Because this compression casting pan is under the big electric current formed action of alternating magnetic field of the high frequency alternation that passes through the compounding machine induction coil, produce induced-current on the stainless iron compound bottom sheet and in short-term, rise to high temperature, realize that pot body and compound bottom sheet are compound fast, therefore, this combination process has following characteristics: the recombination process time is short, and energy consumption is little; Less to the heat-affected zone of pot body in recombination process, original metallurgical structure of pot body is stable, and original performance of compression casting pan pot body can not change; Whole high temperature of stainless iron compound bottom sheet is compound, and each position is heated evenly, and compound bottom sheet is reliable with the pot bluk recombination, the bonding strength height, and compound area is big.Because the compound bottom sheet area coverage is big, the efficient heat generation area is also big, so the thermal efficiency is higher; Because compound through high temperature, its resistance to elevated temperatures is good, but withstand high temperatures and the bottom of a pan can not be out of shape during use, and under hot and cold alternating action, also can keep stable, its heat-resistant anti-fatigue stability is higher.In addition and since compound bottom sheet directly with bottom of pot body smooth compound be one, so its component structural is simple, and is easy to process, can make production technology obtain simplifying, so can control production cost effectively, the raising competitiveness of product.
