Abstract

The utility model relates to a rustproof iron pan, which comprises a pan body and a handle, wherein an oxidizing layer is arranged on the inner surface of the pan body, and a C, N and Fe chemical compound layer formed through carbonitriding is arranged between the pan body and the oxidizing layer and is in the thickness of 15-20 micrometers. The rustproof iron pan which has the functions of rust prevention and iron supplement greatly improves both the corrosion resistance and the wear resistance.

Description

A kind of rustproof iron pot
Technical field
The utility model relates to iron pan, specifically a kind of rustproof iron pot.
Background technology
Iron pan is historical production and the use in existing thousands of years, is easy to the personal ferrous iron that attracts with the additional necessary ferro element of human body, so be subject to people's favor always because it can form in cooker uses, but, its deficiency is that iron pan gets rusty easily, the problem that gets rusty easily in order to change iron pan
In the technology, with simple gas nitriding cast iron is had certain rust-proof effect now, still, its antirust coat easily crisp, easily peel off and come off.
Chinese patent application number 03126592.8 is called " with iron pan and the manufacture method thereof of tin-nickel alloy protective layer " and discloses: with the iron pan of tin-nickel alloy protective layer; comprise the iron pan body; its design feature is: there is the tin-nickel alloy protective layer on the surface at described pot body; the tin-nickel alloy protective layer is attached to the surface of pot body by plating or hot melting way, its thickness is 30~45 μ m.The manufacture method of iron pan is characterized in: fine-grinding and polishing is carried out in the cast iron pan pot surface of moulding, the oil stain on scrub cast iron pan surface as previously mentioned; Cast iron pan pot body is carried out the anode oil removing; Cast iron pan pot body is carried out weak corrosion; In electrolytic cell, add pyrophosphate electrolyte, in electrolyte, add the metallic nickel of metallic tin and trace, cast iron pan pot body is dipped in the electrolyte, make the surface of cast iron pan pot body form one deck tin-nickel alloy protective layer by electrolysis.
China Patent No. 201020240197.3, name is called " rustproof iron pot " and discloses: a kind of iron pan.It comprises the iron pan body, and described iron pan body internal surface is provided with film corrosion protection layer.The utility model structural design advantages of simple, iron pan rust-proof effect effect work, the user is easy to use, and is easy to clean, and the film that tears it down is easily degraded, and easily reclaims environmental protection.
Above-mentioned disclosed technical scheme has certain rust-proof effect, and its deficiency is to have intercepted food to contact with iron pan, has lost iron replenishing function.
The utility model content
Technical problem to be solved: the utility model is not enough for prior art, provides a kind of and has had antirust and rustproof iron pot iron replenishing function.
Technical scheme: a kind of rustproof iron pot, comprise a pot body, handle, it is characterized in that: described inner surface of pot body has oxide layer, C, the N and the Fe compound layer that have carbo-nitriding to form between pot body and oxide layer.
Described C, N and Fe compound layer thickness are the 15-20 micron.
The utility model remarkable result is: 1, the utility model decay resistance significantly improves, after the carbo-nitriding take ε mutually as main compound layer, have Chinese People's Anti-Japanese Military and Political College's gas, rainwater (with zinc-plated, turn blue quite) and anti-seawater corrosion (suitable with cadmium plating) performance.
2, the utility model anti-wear performance significantly improves: C, N infiltrate the compound layer in C, the N of iron pan surface formation and Fe formation, and oxide layer, this is two-layer can to significantly improve a pot body case hardness, namely directly cause anti-wear performance significantly to improve, compare with modified, high-frequency quenching, wear weight loss reduces respectively by 1-2 the order of magnitude or reduces at double.
3, often use the utility model rustproof iron pot, can play the effect into compensating iron for human, more healthy.
Department is detected through the relevant speciality detection, and this technology meets Chinese container food security standard GB1984-1988; Meet simultaneously U.S. FDA (U.S. food safety standard) requirement.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is A place enlarged drawing among Fig. 1.
The specific embodiment
See shown in Fig. 1,2, rustproof iron pot comprises pot body 3, handle 4, and described pot body 3 inner surfaces have oxide layer 1, C, the N and the Fe compound layer 2 that have carbo-nitriding to form between pot body 3 and oxide layer 1.Pot body 3 inner surfaces refer to the surface that makes progress in pot body, and a pot body bottom surface is the one side that directly contacts with burning things which may cause a fire disaster.
Described C, N and Fe compound layer 2 thickness are the 15-20 micron.Described oxide layer 1 thickness is the 100-200 micron.
Carbon symbol C, nitrogen symbol of element N, ferro element symbol Fe.
The salt bath process that the utility model adopts, its salt bath formula is: 1, alkali metal cyanate MCNO(M represents K ion, Na ion).2, oxidation salt: AB1(has another name called KQ500) or Y-1 salt.
Alkali metal cyanate MCNO characteristics: cyanate radical (CNO-) content in this salt is measured the activity of fused salt usually.According to used industrial chemicals and cyanate and cyanide (with CN-expression) content height, fused salt can be divided into low cyanogen, middle cyanogen, high cyanogen type carbo-nitriding salt bath.
Most widely used is that West Germany developed in 1974, and the trade mark is the low cyanogen salt bath of TF-1.China studied in recent years successful J-2 base salt and had the function identical with REG-1 salt with West Germany TF-1 with the Z-1 regenerant salt, and cyanate radical is lower.Since the medium Wen Shike of oxidation salt bath with part take out of a small amount of ooze altogether the nontoxic CO32 of micro-CN contained in the salt-be oxidized to-, therefore can realize pollution-free operation.
The oxidation characteristics of salt AB1: cooling velocity is large, CN behind the oxidation bath isothermal 5-20min-and be zero, CNO2-a little, the flush away saline oxide approximately needs 5-15min.
The utility model only limits to absolutely not these examples.The above only is preferably embodiment of the utility model, only is used for describing the utility model, can not be interpreted as the restriction to scope of the present utility model.Should be pointed out that all any modifications of within spirit of the present utility model and principle, making, be equal to replacement and improvement etc., all should be included within the protection domain of the present utility model.

Claims (2)

1. a rustproof iron pot comprises a pot body, handle, it is characterized in that: described inner surface of pot body has oxide layer, and a compound layer is arranged between pot body and oxide layer.
