Abstract
The present invention is high temperature oxidizing method for surface of iron pot. Un-coated iron pot is likely to rust and coated iron pot may result in negative effect. The present invention treats iron pot through polishing, eliminating its oily dirt and rust and high temperature oxidation to form one blue-black compact ferric oxide layer to protect iron pot. The present invention makes iron pot practical, non-toxic, beautiful and long in service life.
Description
Technical field:
The present invention relates to family's kitchen pot.
Prior art:
Easily get rusty in normal domestic use iron pan surface, and not attractive in appearance.Get rusty and surface aesthetic general the employing for anti-: enamel, spray high temperature varnish, spray non-viscous paint etc., these surface treatment methods have a common drawback to be exactly: in use easily come off.After coming off, the one, do not play rust inhibition, impracticable again, saying nothing of coating and enamel itself may be poisonous.
Summary of the invention:
The objective of the invention is to overcome the deficiencies in the prior art, adopt the brand-new treatment process in a kind of Domestic pot surface, make Domestic pot surface poisonless after the processing, harmless, attractive in appearance, durable, do not come off, and production process is nontoxic.
The objective of the invention is to realize by following technical proposal:
Iron pan (iron pan or steel plate are towards iron pan) all can, the surface is through emery wheel or be stained with the fabric disc of silicon carbide, after polishing or the polished finish, the surface becomes the brand-new no greasy dirt and the glossy surface of iron rust, at short notice, generally be no more than 3 hours after the processing, put into the oxidation of high temperature oxidation stove, after oxidation is good, the naturally cooling of coming out of the stove.
Embodiment:
The present invention can specifically implement by the following example: with the iron pan blank on the mill pot machine of special use with emery wheel or be stained with the fabric disc of powder emery; grinding and polishing processing is carried out on the surface; remove the greasy dirt and the iron rust on surface fully; make surface-brightening; surface roughness is controlled between the 0.4 μ m-3.2 μ m; slightly degree of making is greater than 3.2 μ m; the surface is bright and clean inadequately; attractive in appearance and the use of influence pot; slightly degree of making is less than 0.4 μ m; the surface is too bright and clean may remove zone of oxidation when the life-time service spades, does not reach the surface protection effect.
The iron pan surface of light under the hot conditions of aerobic, can produce the blue-black Z 250 Fe of one deck after grinding and polishing
3O
4Zone of oxidation, fine and close and firm.Oven temperature is controlled at 280 ℃～700 ℃, and optimum temps is 450 ℃～550 ℃.30 minutes to 90 minutes time, that temperature is lower than 280 ℃ of main generations is ferric oxide Fe
2O
3, redness of the skin or complexion, this layer thickness is low, and the turbid power of rust-proofing is poor, and color is not attractive in appearance, if temperature surpasses 700 ℃, pot is yielding during operation, and surface oxide layer is inhomogeneous.
Baking oven can use the outer heated oven of common electrical baking oven, combustion gas internal heating baking oven, combustion gas or coal, and to the requirement of baking oven: cavity volume is greater than 0.5M
3, have temperature to show and Controlling System.
In order to strengthen Fe

4Antirust ability, can evenly be coated with the thin edible oil of one deck on the iron pan surface.
Claims (4)
1, a kind of high-temperature oxidation method on iron pot surface, it is characterized in that: with emery wheel or be stained with the fabric disc of powder emery, after removing the greasy dirt and iron rust on iron pan surface, again iron pan is put into the baking oven of oxygen, 550 ℃～700 ℃ heated oxides of temperature make the iron pan surface generate the black-and-blue Z 250 Fe of one deck
3O
4Zone of oxidation.
2, require 1 described a kind of high-temperature oxidation method on iron pot surface according to power, it is characterized in that: degrease and iron rust after surfaceness 0.4 μ m-3.2 μ m between.
3, require 1 described a kind of high-temperature oxidation method on iron pot surface it is characterized in that according to power: oxidization time 30～90 minutes.
4, require 1 described a kind of high-temperature oxidation method on iron pot surface it is characterized in that according to power: behind high temperature oxidation, the surface is coated with one deck edible oil.
