According to metal phase change principle (Heat-Treatment of Steel principle), sub-eutectoid steel austenite degree of supercooling in phase transformation is smaller, more
The over-cooling structures such as bainite, martensite are not easily formed, more form the ferritic structure that intensity is low, plasticity is good, therefore work as
When placing 2 even more steel on rack gear, steel rises the environment temperature in peripheral cell domain from heat dissipation, effectively reduces
Degree of supercooling promotes ferritic transformation, to reduce the generation of bainite.
When placing 2 steel, cooling velocity is substantially reduced, and can preferably inhibit the generation of abnormal structure.This slow cooling method
2 steel are not limited to put, if cold bed counterweight is able to satisfy, better slow cooling effect can be played by placing 3 even more steel,
Or big specification steel can be extended to or play preferable effect.This slow cooling method is for exhausted most in sub-eutectoid steel
Number bar steel grade is all suitable for, and can become a kind of new cold mode of control, is belonged to a kind of innovation of advanced control cooling method, is tradition
One much progress of bar production.
Round steel on skirtboard 1 can be carried out to the right transport transfer by moving tooth plate 6 by the present invention, and pass through conveying roller 3
