Description
One, technical field
The present invention relates to daily utensil, the vessel that are used for article-containing and are used to burn, bake, stew, boil that particularly electrodeless nonmetal thing and metal object are combined as a whole and make belong to the daily utensil processing technique field.
Two, background technology
Have anti-oxidant, antiacid caustic corrosion, many advantages such as high temperature resistant with the vessel of electrodeless nonmetal making such as rock and pottery, mud, sand, therefore, liked by people always, nowadays, in daily life, daily utensil tableware use amount maximum.In the cooker, earth pot, buckpot that Chinese use.The stone pot that Japan, Korean use, bowl, baking tray etc. are used also very extensive.But stone, pottery, mud, the earth pot vessel of routine techniques production at present, the greatest problem of existence is crisp because of above-mentioned nonmetallic materials matter, is unable to undergo thermal shock, therefore there is easy collision broken, shortcoming easy to crack, when particularly making barbecue type pot (dish), the phenomenon of cracking is particularly serious.
In order to address the above problem, the Korea S manufacturer casts the ectosome of stone pot, stone ovenware with the aluminum metal after the thermosolization, makes it to become stone pot, a stone ovenware by the aluminum metal inclusion.Though this technical scheme is feasible, the shortcoming that exists is: 1. cost height.Because can cast after the stone body of stone pot, stone ovenware need heat, otherwise the casting shortcoming appears.Therefore cracking phenomena has appearred in part stone body when the casting heating.2. it is narrow that material is selected face.Can only select heatproof, the anti-type stone material that splits to use, common building stones can't be made.The domestic patent No.: ZL03214643.4 proposes " be with one in the outside of stone pot body (1) and match with a pot shape, and the metal shell that is solidified as a whole with it (2) ".Metal after this patent will be dissolved " add certain thickness metal in that the stone pot is external, car becomes the metal shell of smooth and beautiful appearance again " can be realized.If with " directly processing metal shell (2) is combined as a whole it and the stone pot body (1) that processes again " this formulation only is a kind of imagination, because it fails to propose specific embodiment, the two matches to accomplish stone pot body and metal shell, can only understand with ordinary skill and implement this scheme, like this, the two tolerance fit and processing and fabricating on suitable difficulty is arranged, processing cost is also very expensive, the particularly processing of stone goods, be difficult to guarantee machining accuracy at present, if stone pot body size is can't enter in the metal shell that fits tightly greater than metal shell, if stone pot body is less than metal shell, can not accomplish to match, the two also can not accomplish to be solidified as a whole.For above-mentioned reasons, can't realize so far both at home and abroad that " directly processing metal shell (2) is combined as a whole it and the stone pot body (1) that processes again." I propose among the patent No. ZL200420006208.6 at home, and " pot made from stone, pottery, mud, sand is inner pan body (1), make a metal shell as outer pan body (2) in its outside with metal material, it is characterized in that leaving the space that average distance is 0.2mm-15mm between inner pan body (1) and the outer pan body (2), filler (3) is housed in this space.Though " this patent realizes one stone, pottery, mud, the earth pot product of " directly process metal shell (2), again it and the stone pot body (1) that processes are combined as a whole ".This patent has solved the broken problem of electrodeless non-metallic body anticollision to a certain extent, but lacks the fastening effect to electrodeless non-metallic body, and this product uses under heat temperature condition and cracking phenomena still occurs.So requiring electrodeless nonmetal outer metal shell is not only will coincide to paste mutually also to require to have the very big power of fiting, electrodeless like this non-metallic body is subjected to fiting the power effect, do not expand outwardly the space when expanded by heating, only in this way electrodeless non-metallic body could guarantee no longer to produce cracking phenomena in use.
Three, summary of the invention
Purpose of the present invention is intended to overcome the deficiency of above-mentioned prior art and a kind of feasible new solution that proposes.Solve the warm technical barrier that ftractures of vessel chance heat that present electrodeless nonmetallic materials are made.In order to achieve the above object, the present invention realizes like this, make a metal tight loop (2) in its outside at the non-metallic body made from electrodeless nonmetallic materials such as stone, pottery, mud, sand (1), the size at this metal tight loop (2) and the fastening place of non-metallic body (1) should be smaller or equal to zero.This metal tight loop (2) is added the outside that is linked in non-metallic body (1) after the thermal expansion.After metal tight loop (2) cooling non-metallic body (1) is polymerized to one tightly.Metal tight loop (2) thermal expansion size is relevant with heating-up temperature, when generally being heated to 300 ℃-800 ℃, metal tight loop (2) with the 200mm bore is that example can expand outwardly about 1-3mm under this temperature, this does not need very accurate machining accuracy for non-metallic body (1), the non-metallic body of making for ceramic-like (1) is slightly fired distortion and also can be used, and is easy to non-metallic body (1) is pressed in the metal tight loop (2) after metal tight loop (2) thermoplastic.Preferably select for use between the 0--5mm for metal tight loop (2) and non-metallic body (1) fit dimension, the heating-up temperature of regulating metal tight loop (2) just can be sleeved on metal tight loop (2) outside of non-metallic body (1), and cooled metal tight loop (2) is fixedly set in non-metallic body (1) outside with the very large power of fiting.This physics power of fiting is a kind of powerful cohesion, and the expansive force that non-metallic body (1) is produced when use is heated does not expand outwardly, and no longer ftractures when hot to guarantee that non-metallic body (1) is met.Requiring electrodeless non-metallic body (1) and metal tight loop (2) like this is not only to coincide to paste mutually, but requires metal tight loop (2) also should have certain power of fiting.
Certainly, the size of this power of fiting has material impact, the too small effect that does not have confined expansion of the power of fiting, the still old cracking phenomena of electrodeless non-metallic body (1) for the cracking resistance of non-metallic body (1).Heating-up temperature during therefore, for the material of metal tight loop (2), thickness and suit can be done certain adjustment according to material, the thickness of non-metallic body (1).The material that metal tight loop (2) is selected for use is not less than 0.2mm as steel, iron, stainless steel, its thickness of aluminium, and needed heating-up temperature should only in this way could guarantee effectively that product processed has reliable cracking resistance at 50 ℃-1200 ℃ during suit.
The present invention compared with the prior art, owing to adopted metal tight loop (2) heating jacket to be contained in the process of non-metallic body (1), make the tolerance fit space of the two very big, it can economy be combined as a whole metal tight loop (2) and non-metallic body (1) reliably, and non-metallic body (1) cracking resistance, anticollision performance have been strengthened effectively by metal tight loop (2), greatly improve crisp, the thermo-labile impact property of traditional electrodeless nonmetallic matter, expanded its scope of application.And can low-cost production go out glass, pottery with this technology, the cracking resistance that nonmetallic materials such as stone are made, the novel vessel of cold-resistant thermal shock.
