Abstract
The invention discloses a kind of precision piece part watch surface chromium base alloy carbides cladding process method, part and chromizing agent are positioned in inner furnace by design proportion, load outer furnace after sealing and regulate outer furnace mouth from the horizontal by 40-60 degree angle, starter motor afterwards, inside and outside flue is driven to rotate, in the process of rotating, temperature of reaction 1000 DEG C is heated to it, and is incubated 6 hours; Inside and outside flue continues to rotate, and stops insulation, lowers the temperature, when temperature drops to 500 DEG C, inside and outside flue stops operating, and continues cooling, until temperature drops to 100 DEG C, is taken out by inner furnace, air cooling, to normal temperature, opens inner furnace lid afterwards, pours out part with chromizing agent both to be separated.The piece surface Chromizing Layer obtained is very even, and also effectively prevent chromizing agent caking phenomenon, during chromising, chromizing agent can be reused again, cuts the waste, and reduces production cost.
Description
Technical field
The invention belongs to metal parts Surface heat-treatent technical field, be specifically related to a kind of carbon steel accurate finding surface croloy carbide coating New Method for Processing.
Background technology
Existing carbon steel part surface chromising thermal treatment process, that carbon steel part is manually mixed according to a certain percentage with chromizing agent, then shove charge, sealing, be heated to temperature of reaction, static not whipped state is at heat-processed medium carbon steel part and chromizing agent, certain hour is kept under high temperature, carbon effect in chromizing agent and part, certain thickness Chromizing Layer is formed at piece surface, in chromising process, part and chromizing agent are in static not whipped state, there is Chromizing Layer non-uniform phenomenon, chromizing agent easily sticks in piece surface, be difficult to remove totally, and chromizing agent easily lumps, the penetration enhancer that again lumps during chromising cannot be reused, cause very large waste.
Summary of the invention
In order to overcome the above-mentioned technical problem that prior art field exists, the object of the invention is to, a kind of precision component surface croloy carbide coating New Method for Processing being provided, obtaining the Chromizing Layer of uniform thickness at piece surface.
A kind of precision component surface provided by the invention croloy carbide coating New Method for Processing, comprises the following steps:
(1) part and chromizing agent are positioned in inner furnace by design proportion, inner furnace lid are fixed on inner furnace:
(2) sealing agent is positioned in sealing agent that inner furnace covers fills with;
(3) inner furnace of good seal is put into outer furnace, make inner furnace mouth identical with the direction of outer furnace mouth, then cover outer furnace lid;
(4) regulate outer furnace, make outer furnace mouth from the horizontal by 40-60 degree angle, starter motor afterwards, the outer furnace that driven by motor is attached thereto rotates, and outer furnace drives inner inner furnace to rotate then;
(5) inside and outside flue continues to rotate, and is heated to temperature of reaction 1000 DEG C, and is incubated 6 hours in the process of rotating to it;
(6) inside and outside flue continues to rotate, and stop insulation, lower the temperature, when temperature drops to 500 DEG C, inside and outside flue stops operating, and continues cooling, until temperature drops to 100 DEG C, taken out by inner furnace, air cooling is to normal temperature;
(7) open inner furnace lid, pouring out part with chromizing agent is separated both.
A kind of precision component surface provided by the invention croloy carbide coating New Method for Processing, its beneficial effect is, regulate outer furnace mouth from the horizontal by 40-60 degree angle, the gas being conducive to producing in heat-processed is discharged fast; Inside and outside flue continues to rotate in particular during a heating process, and the piece surface Chromizing Layer obtained is very even, and also effectively prevent chromizing agent caking phenomenon, during chromising, chromizing agent can be reused again, cuts the waste, and reduces dirt and produces cost.

(2) 0.5Kg sealing agent is placed in sealing agent that inner furnace covers fills with;
(3) inner furnace of good seal is put into outer furnace, make inner furnace mouth identical with the direction of outer furnace mouth, finally cover outer furnace lid;
(4) be adjusted to inside and outside flue mouth from the horizontal by the direction at 60 degree of angles, starter motor drives inside and outside flue to rotate;
(5) inside and outside flue continues to rotate, and is heated to temperature of reaction 1000 DEG C, and is incubated 6 hours in the process of rotating to it;
(6) inside and outside flue continues to rotate, and stop insulation, lower the temperature, when temperature drops to 500 DEG C, inside and outside flue stops operating, and continues cooling, until temperature drops to 100 DEG C, taken out by inner furnace, air cooling is to normal temperature;
(7) open inner furnace lid, pouring out part with chromizing agent is separated both.
Claims (1)
