Abstract
The invention discloses an anti-oxidation heat treatment method for steels. The method includes the following heat treatment steps that step one, the steels are subjected to rough machining, and then the steels are placed in a heating furnace for preheating at the temperature of 550 DEG C to 600 DEG C for 5 hours; step two, after the steels are subjected to the preheating treatment, then the steels are subjected to high temperature quenching at the temperature of 1000 DEG C to 1050 DEG C, and the thermal insulation is performed for 2 hours; step three, boron resins are coated on the surfaces of the steels, the steels are placed in a heat maintaining furnace, the in-furnace temperature is increased to450 DEG C to 550 DEG C, and the thermal insulation is performed for 4 hours; and step four, after the steels are subjected to the thermal insulation treatment, when the temperature of the heat maintaining furnace is decreased to 100DEG C to 150 DEG C, the steels are taken out of the furnace, and the steels are subjected to air cooling to the room temperature. According to the method, the steels produced by the heat treatment method are not easy to be oxidized, and the heat treatment method is used in industry.
Description
Technical field
The present invention relates to the heat treating method that uses in a kind of industry.
Background technology
Steel not only use in industrial production, in daily life, use the material of steel casting also to be seen everywhere, so the applicable of steel be closely bound up with us, but steel in use are easy to oxidized generation iron rust, cause people in the process of using, not only to affect attractive in appearance, the strength decreased that also may cause steel causes the damage of object not use, so, how to avoid the oxidation corrosion of steel, become people's problem anxious to be resolved.
Summary of the invention
The present invention is to the proposition of above problem, and a kind of heat treating method of research and design, can not well prevent in order to the steel that solve existing heat treating method production steel oxidation shortcoming.The technique means that the present invention adopts is as follows:
A kind of antioxidant heat treatment method of steel is characterized in that comprising following heat treatment step:
(1) described steel place preheating in the process furnace through after the roughing, 550 ℃～600 ℃ intensification preheatings, continue 5 hours;
(2) described steel preheating carries out quench hot after processing, and quenching temperature is incubated 2 hours at 1000 ℃～1050 ℃, and steel are placed the quenching oil quenching, when steel are cooled to 80 ℃～120 ℃, takes out steel from quenching oil, and air cooling is to room temperature;
(3) with the upper boron resin of described steel surface spraying, and put into holding furnace, temperature in the stove is risen to 450 ℃～550 ℃, be incubated processing, continue 4 hours;
(4) after the insulation of described steel is processed, behind holding furnace temperature drop to 100 ℃～150 ℃, described steel are taken out in stove, air cooling is to room temperature.
To room temperature, can also be water-cooled as the air cooling described in the preferred described step (2).
Thermal treatment worker method of the present invention is before insulation compared with the prior art, the spraying boron resin, boron resin pyrolytic decomposition in the insulating process, a part is evaporated, a part forms boride and is affixed on steel surface, avoided steel exposed with air in the shortcoming of oxidation very easily.
The present invention has simple, can be used for industrial mass manufacture, is suitable for the needs that large-scale industrial is produced, and has higher engineering using value, and it puts goods on the market and will produce significantly Social benefit and economic benefit.
