Abstract
The invention provides a rapid tempering method for alloy steel. The method comprises the following steps that firstly, the alloy steel is placed in an electric box furnace to be heated to 920 DEG C, and then heat preservation is conducted for 30 min; secondly, the alloy steel obtained in the first step and obtained after heat preservation is placed in 12% saline water in which ice blocks are added to be cooled to 25 DEG C; and thirdly, the alloy steel obtained in the second step is heated again to 620 DEG C with the speed of 200 DEG C/s, and after heat preservation is conducted for 50 min, cooling is conducted to the room temperature. Compared with a conventional method, the tenacity of the alloy steel can be improved through the rapid tempering method for the alloy steel.
Description
Technical field
The present invention relates to steel technical field, particularly relate to the rapid annealing method of a kind of steel alloy.
Background technology
Under normal circumstances, automobile high-strength steel are required for using, in hot procedure through hot pressing processing aftershaping
The structure property of steel changes (such as dynamically/static recovery and recrystallization etc.), different alloying elements and heating technique
