Description

Selenium germanium iron alloy pan and manufacture method thereof

The present invention relates to life cooker field, is a kind of selenium germanium iron alloy pan and manufacture method thereof specifically.

Be used at present to cook, cooking and the cooker multi-purpose stainless steel or the aluminum of heating up water make.The stainless steel cooker can not discharge the trace element that is of value to HUMAN HEALTH in the cooking process.Aluminum products cooker life-time service can make brain decline and aging, unfavorable HUMAN HEALTH.The frying pan that China casts with the pig iron contains elements such as iron, silicon, manganese, and this pot can discharge ferro element in the process of cooking, be of value to enriching blood of human body, but its trace element that is of value to human body is few.Chinese patent application number be 89105763.3 and 89105751.X in, two kinds of iron pans that contain zinc, copper, germanium, selenium and rare earth element are disclosed, these elements have protective effect on cancer risk, the also development of favourable children's intelligence, but unsatisfactory part is arranged also, as the zinc too high levels, human body is also had retroaction, so zinc content to be selected suitably.The iron pan phosphorus content is too high in the foregoing invention, can make pot produce red brittleness, thereby shorten the work-ing life of pot.Rare earth element has 17 kinds in addition, but they are not people's bulk-growth trace elements necessary.How unexposed selenium adds in these two pieces of documents.Two kinds of adding methods of zinc also have its weak point.The boiling point of selenium is 690 ℃, and it must gasify in 1450 ℃ molten iron, if therefore add the pure selenium material, then can not preserve the selenium element in the iron pan.Though the available zinc oxide of zinc element, zinc sulphide form add molten iron, but zinc oxide needs 1975 ℃ of just fusions, therefore be not all right for come its temperature of smelting molten iron with cupola furnace, because the cupola furnace smelt iron generally can only reach 1500 ℃, must use electric furnace or other blast furnaces for this reason instead and just can reach 1975 ℃, this has not only increased the facility investment expense, and has increased energy consumption greatly, thereby cost is improved greatly.If zinc metal sheet is added at the sprue gate, metallic zinc easily gasifies, thereby sets off an explosion, and makes operational hazards, unfavorable operator's safety, and zinc content can not be guaranteed in the iron pan simultaneously.

The invention provides a kind of pot and manufacture method thereof of selenium germanium iron alloy of cheapness, can replenish the trace element of needed by human body effectively, and its manufacture method is also safe and reliable, its raw material also is easy to get.

Iron pan of the present invention is to adopt the iron level that contains 18 kinds of elements to make.The component and the content of this alloy following (weight percent):

Se:0.005～0.008, Ge:0.030～0.06, Cu:0.10～0.25, Zn:0.006～0.025, Mo:0.003～0.007, Al:0.003～0.006, Ca:0.001～0.003, Co:0.02～0.04, Cr:0.005～0.008, Mg:0.0003～0.0006, Mn:0.3～0.5, Ni:0.010～0.015, Si:1.20～1.40, Sn:0.08～0.15, Ti:0.08～0.15, V:0.005～0.009, P:0.003～0.005, surplus are Fe.

Cook with iron pan of the present invention, cooking and heating up water can discharge 17 kinds of trace elements beyond the dephosphorization, wherein 11 kinds of trace element that trace element is a needed by human, particularly selenium, germanium, copper, zinc, molybdenum, iron and manganese seven big trace elements are generally acknowledged to have preventing cancer function by medical science, nutritionist.Table 1 has been listed the effect of various trace elements to human body.

Can find out that from table 1 18 kinds of trace elements of iron pan of the present invention not only have antitumous effect, and to human body grow, generation anti-ageing, that prevent various diseases is all with health role.Therefore be a kind of effective way of human body constantly being replenished required trace element.

How to add be one of key of the present invention for selenium, germanium and zinc alloy in the iron pan of the present invention.Selenium germanium pure substance is expensive material, and selenium will gasify at 690 ℃, therefore adopt pure selenium and germanium metal that production cost is improved, and selenium still can not be retained in the iron pan.Same zinc element then will be gasified at 907 ℃ as adding with the zinc metal, if add with oxide form, raises the cost again.

The present invention is that to select the ferrous manganese ore and the pig iron for use be main raw material.In order to reduce the fusing point of each elementary composition in the ferrous manganese ore, added Wingdale (lime carbonate), can reduce the fusing point of oxide compound.Ferrous manganese ore contains more than 20 kind of elements such as selenium, germanium, copper, iron, zinc, molybdenum, magnesium.Thereby guaranteed that iron pan contains 18 kinds of trace elements that are of value to human body.Ferrous manganese ore is wanted considerably cheaper than pure selenium and germanium metal, and it is also many to originate, and is a kind of cheap and good-quality raw material.

Iron pan casting technique of the present invention is as follows:

(1) elder generation weighs copper, the pig iron, ferrous manganese ore and Wingdale and places in the cupola furnace, gives heat at 900～1100 ℃, and progressively is heated to 1250～1500 ℃ of meltings, and the molten iron that melting gets is delivered to intermediate frequency furnace 1450 ℃ of insulations.

(2) alloy hot metal in the intermediate frequency furnace is delivered to a pressure pot machine and be cast into iron pan.

The iron pan of die casting is rebuild burr again, inside and outside polishing, and mounting ear is qualified product waiting.

Proportioning raw materials of the present invention is: copper: the pig iron: ferrous manganese ore: Wingdale=0.2～0.3: 87～90: 5～7: 4.5～7(weight percent).Above-mentioned ferrous manganese ore is relatively more moderate, and too high meeting produces detrimental action to human body, and the trace element of crossing in the low pot has just discharged soon.The extrusion process of iron pan is identical with traditional skillet.

The function of the various elements of table 1 in human body

Embodiment:

Weigh by ferrous manganese ore 8Kg, pig iron 120Kg, Wingdale 8Kg, copper 0.36Kg, and place in the cupola furnace, give heat earlier to 1100 ℃, again 1500 ° of following meltings, the alloy hot metal that obtains is sent into the intermediate frequency furnace insulation, delivers to and presses the pot machine to be cast into iron pan.Iron pan is carried out the burr trimming, and to polishing inside and outside it, mounting ear handle etc. just become iron pan specious, economical and practical, with health role.
