Description
Technical field
The utility model relates to a kind of fixing liner plate formula van-type process furnace, and especially a kind of boron steel steel plate, or/and quenching box-type furnace equipment is strengthened in the thermoforming segmentation under steel pipe high temperature, belongs to metal forming technical field.
Background technology
Boron steel steel plate is as one emerging superstrength thermoforming steel plate, and production technique is divided into 4 stages:
(1) heat: the principal crystalline phase of as-annealed condition is organized as ferritic boron steel steel plate or/and steel pipe is heated to the temperature required for thermal treatment;
(2) transmit: boron steel steel plate is sent in mould to be punched;
(3) be shaped: be at high temperature shaped by die stamping;
(4) cool: by work-piece cools to temperature required, be generally quenching process: if now boron steel is austenitic state, control different speed of cooling in different zones, different phase transformation can occur:
A) hard area cools (>25 DEG C/sec) fast: if the heating phase is by more than workpiece heat to austenite transition temperature, be generally 930 DEG C, under this speed of cooling, microtexture changes to martensite microtexture, obtain intensity and extreme hardness, part HS1150 that plasticity is lower, its intensity can reach 1500 ~ 2000MPa, and plasticity is greater than 5%;
B) soft district cools at a slow speed (<25 DEG C/sec): if the heating phase is by more than workpiece heat to austenite transition temperature, be generally 930 DEG C, under this speed of cooling, by controlling different speed of cooling, in the process that austenite structure transforms, can Slow cooling, change to ferrite and pearlite microtexture, obtain intensity and hardness is higher, plasticity is good part HS400;
C) do not undergo phase transition: if the heating phase is not by more than workpiece heat to austenite transition temperature, speed of cooling changes in any case, and workpiece crystalline phase is organized and do not changed, and is still ferritic-pearlitic tissue.
If on a complete workpiece, different quenching technology more than different zones occurs, different zones obtains the workpiece of different physical strength, is just called segmentation reinforcing process, or soft district technique.
Can be obtained the boron steel material of varying strength and plasticity by above-mentioned technique, typical case is as shown in table 1.
