Abstract
A kind of ordinary carbon steel rta technique, it is characterized in that being first steadily fitted into workpiece to be annealed in annealing furnace, installed according to the shape of part and structural stratification and carry out order heat treatment again:Using fast heating method, part was heated to 100 DEG C~120 DEG C of below phase transition temperature in 10 minutes~15 minutes, takes out workpiece, puts it into quick cooling 1 minute~2 minutes in water, then taken out from water and be cooled to room temperature in atmosphere.Workpiece annealing time can be reduced, annealing operation is easy, and annealing effect is good, and production efficiency is high, cost is low, and suitable for a variety of carbon steels, as long as adjusting heating-up temperature according to different steel grades, flexibility is strong, applies to multi items Single unit job lot production, has application value.
Description
Technical field
The present invention relates to a kind of heat treatment method, particularly a kind of ordinary carbon steel rta technique.
Background technology
At present, carbon steel method for annealing be by by quenched or with certain degree of hardness carbon steel be heated to phase transition temperature with
Lower 50 DEG C~60 DEG C, then furnace cooling is to less than 200 DEG C, then is cooled to room temperature in atmosphere, cool time length, production efficiency
It is low, cost is high.
The content of the invention
The invention aims to overcome the above-mentioned weak point of prior art, and a kind of reduction annealing time is provided,
Annealing operation is easy, and annealing effect is good, the ordinary carbon steel rta technique that production efficiency is high, cost is low.
For achieving the above object, the concrete technology method that the present invention uses is first steadily to load workpiece to be annealed to move back
In stove, installed according to the shape of part and structural stratification and carry out order heat treatment again:Using fast heating method, by part 10
Minute~15 minutes in be heated to below phase transition temperature 100 DEG C~120 DEG C, take out workpiece, put it into quick 1 point of cooling in water
Clock~2 minute, then taken out from water and be cooled to room temperature in atmosphere.
The present invention can reduce workpiece annealing time, annealing operation is easy, annealing effect due to using process above method
Good, production efficiency is high, cost is low, and suitable for a variety of carbon steels, as long as adjusting heating-up temperature according to different steel grades, flexibility is strong, fortune
For multi items Single unit job lot production, there is application value.
Specific embodiment
First workpiece to be annealed is steadily fitted into annealing furnace, is installed according to the shape of part and structural stratification and carries out order again
Heat treatment:Using fast heating method, part was heated to 100 DEG C~120 DEG C of below phase transition temperature in 10 minutes~15 minutes,
Workpiece is taken out, puts it into quick cooling 1 minute~2 minutes in water, then taken out from water and be cooled to room temperature in atmosphere.
Claims (1)
