Abstract
The invention discloses a coloring disposing method of black metal surface, which comprises the following steps: making black metal into element; heating to certain temperature between 200 and 400 deg. c; insulating 40-60 min; cooling black metal element naturally; coating a layer of protective oil on the element surface.
Description
Technical field
The present invention relates to the surface treatment method of ferrous metal, especially a kind of surface coloured silkization treatment process.
Background technology
General ferrous metal surface treatment process comparative maturity, but also exist operator's technical requirements higher, complex process, the cost height as workmanship of spraying plastics, needs before the plastic-blasting through could plastic-blasting behind the complicated bonderizing.And need to buy starting material, and also harmful to the operator, plastic-blasting and dry equipment and have high input, efficient is low, contaminate environment.
Summary of the invention
The purpose of this invention is to provide a kind of pollution-free, processing method for ferrous metal surface colorizing that cost is low,, improve the solidity to corrosion of product, increase the service life so that the part outside surface is more attractive in appearance.
For this reason, technical scheme of the present invention is: processing method for ferrous metal surface colorizing, and concrete steps are: the part that ferrous metal is made is heated to certain temperature and insulation, and be 200 ℃～400 ℃ heat-up time, and soaking time is 40 minutes～60 minutes; Then, the part naturally cooling that ferrous metal is made; At last, the piece surface of making at ferrous metal is coated with the last layer preservative oil.
In technique scheme, can on the continous way machining production line, realize, with ferrous metal make part constantly be sent on the guipure of coloured silkization stove, promptly finish the whole heat coloring process that adds from import to outlet; Coloured silk dissolves next part naturally cooling, is coated with the last layer preservative oil at piece surface then.
Beneficial effect: described processing method for ferrous metal surface colorizing, technical process is short, the efficient height, energy consumption is low, pollution-free, cost is low, simple to operate, and less to operator's dependency, its cost performance is better than the antirust processing of general ferrous metal surface.In different temperature and times, the part workpiece can change into shades of colour by coloured silk, and as vermilion red, yellow, blueness, purple etc., piece surface is attractive in appearance, can reach antirust, etch-proof purpose again.
Embodiment
Embodiment 1: the part that ferrous metal is made is heated to 300 ℃, and is incubated 50 minutes; Then, the part naturally cooling that ferrous metal is made; At last, the piece surface of making at ferrous metal is coated with the last layer preservative oil.The color of piece surface is blue, protection against corrosion again promptly attractive in appearance, non-corrosive.
Embodiment 2: with ferrous metal make part constantly be sent on the guipure of coloured silk stove of production line, temperature is 200 ℃, the time is 40 minutes; Coloured silk dissolves next part naturally cooling, promptly finishes the whole heat coloring process that adds from import to outlet; Be coated with the last layer preservative oil at piece surface then.The color of piece surface is light yellow, protection against corrosion again promptly attractive in appearance, non-corrosive.
Following table one is ferrous metal piece surface coloured silkization color and temperature, timing relationship table:
