Abstract
The invention discloses a heat treatment process for an antirust steel plate. The process is characterized by comprising the following process steps that (1) preheating treatment is conducted, specifically, the steel plate is placed into a heating furnace, and the temperature of the heating furnace is increased to 450-600 DEG C; (2) heat treatment is conducted, specifically, the temperature of the heating furnace where the steel plate is placed is increased to 950-1100 DEG C, and the temperature is kept for 4 h; (3) quenching is conducted, specifically, the taken-out steel plate is placed into quenching oil to be cooled; and (4) tempering is conducted, specifically, the steel plate is placed into a tempering furnace after quenching cooling, the temperature of the tempering furnace is increased to 550-600 DEG C, the temperature is kept for 2 h, the steel plate is taken out and placed into a solution containing sodium hydroxide and sodium nitrite, and the steel plate is water-cooled to the room temperature. The steel plate produced through the heat treatment process is not prone to oxidation corrosion and rust, and the heat treatment process is used for industrial application.
Description
Technical field
The present invention relates to the Technology for Heating Processing used in a kind of industry.
Background technology
In existing commercial production, steel plate all can be used in a lot of places, a lot of industrial equipments are all as shell with steel plate, internal structure also has a lot of local use steel plate, in daily life, the use of steel plate is also seen everywhere, but we can find, after wind and weather, a lot of steel plates all can engender rust, be directed at we use process in not only very unsightly, more can cause the reduction of the intensity of steel plate, cause that steel plate outer layer is soft rust entirely, cause the damage of whole object, therefore how preventing steel plate from getting rusty is our problem anxious to be resolved.
Summary of the invention
The present invention proposition to problem above, and research design one Technology for Heating Processing, in order to solve the steel plate after existing Technology for Heating Processing produces in the process used, it is easy to the shortcoming got rusty.The technological means that the present invention adopts is as follows:
The Technology for Heating Processing of a kind of Rustproof Steel Plate, it is characterised in that comprise the following steps that:
(1) the pre-heat treatment: put into by steel plate in heating furnace, raises the temperature of heating furnace, makes up to 450 DEG C-600 DEG C, pass into methanol as protective gas, continues 3 hours；
(2) heat treatment: the temperature being placed with the heating furnace of steel plate is risen to 950 DEG C-1100 DEG C, continues 4 hours；
(3) quenching: put in quenching oil by the steel plate of taking-up and cool down, when steel billet temperature is down to 80 DEG C-150 DEG C, takes out steel plate, and air cooling is to room temperature；
(4) temper: the steel plate after quenching cooling is put in tempering furnace, raise furnace temperature, make up to 550 DEG C-600 DEG C, continue 2 hours, take out steel plate and put in sodium hydroxide and sodium nitrite solution, when solution temperature is down to 50 DEG C-80 DEG C, inserting film forming matter, inhibition antirust agent, antioxidant in solution, water-cooled is to room temperature.
Described steel plate cools down in above-mentioned steps (3) is quenched in quenching oil, it is also possible to be air blast cooling.
Compared with the prior art, the invention have the advantages that
1, Technology for Heating Processing of the present invention, inserts inhibition antirust agent, antioxidant in the solution of tempering cooling, slows down the speed that steel plate in use gets rusty.
2, Technology for Heating Processing of the present invention, inserts film forming matter in the solution of tempering cooling, makes the surface of steel plate after process have one layer of rust-preventing film, will not get rusty when rust-preventing film exists.
The present invention has simple, can be used for industrial mass manufacture, is suitable to the needs that large-scale industrial produces, and has higher engineer applied and is worth, and it puts goods on the market and will produce Social benefit and economic benefit significantly.
Detailed description of the invention
The Technology for Heating Processing of a kind of Rustproof Steel Plate, it is characterised in that comprise the following steps that:
(1) the pre-heat treatment: put into by steel plate in heating furnace, raises the temperature of heating furnace, makes up to 450 DEG C-600 DEG C, pass into methanol as protective gas, continues 3 hours；
(2) heat treatment: the temperature being placed with the heating furnace of steel plate is risen to 950 DEG C-1100 DEG C, continues 4 hours；(3) quenching: put in quenching oil by the steel plate of taking-up and cool down, when steel billet temperature is down to 80 DEG C-150 DEG C, takes out steel plate, and air cooling is to room temperature；
(4) temper: the steel plate after quenching cooling is put in tempering furnace, raise furnace temperature, make up to 550 DEG C-600 DEG C, continue 2 hours, take out steel plate and put in sodium hydroxide and sodium nitrite solution, when solution temperature is down to 50 DEG C-80 DEG C, inserting film forming matter, inhibition antirust agent, antioxidant in solution, water-cooled is to room temperature.
Described steel plate cools down in above-mentioned steps (3) is quenched in quenching oil, it is also possible to be air blast cooling.
Technology for Heating Processing of the present invention, inserts inhibition antirust agent, antioxidant in the solution of tempering cooling, slows down the speed that steel plate in use gets rusty.The solution of tempering cooling inserts film forming matter, makes the surface of steel plate after process have one layer of rust-preventing film, will not get rusty when rust-preventing film exists.Can be used for industrial mass manufacture, be suitable to the needs that large-scale industrial produces, have higher engineer applied and be worth, it puts goods on the market and will produce Social benefit and economic benefit significantly.
The above; it is only the present invention preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; any those familiar with the art is in the technical scope that the invention discloses; it is equal to replacement according to technical scheme and inventive concept thereof or is changed, all should be encompassed within protection scope of the present invention.
