Technical field
High-temperature heat treatment heating furnace is the utility model is related to, specifically, is related to a kind of intelligence of hypereutectoid steel spheroidizing
Can control device.Using the linkage of mechanical action outside electric in-furnace temperature and stove, by intelligent control, realize that hypereutectoid steel forging exists
Balanced cooling velocity is obtained in heat treatment spheroidizing, tissue crystal grain is more refined, more uniformity.
Background technology
Middle-size and small-size cold roll typically from 9Cr2MoV, 86Cr2MoV7, MC5, MC3, etc. hypereutectoid steel material, it is excessively common
Analysis steel generally first uses normalizing process after forging, eliminates net carbide, then carries out spheroidizing again.Mainly make in steel
Carbide spheroidization, obtain equally distributed spherical or granular carbide the tissue on ferrite matrix.Spheroidizing is main
Purpose is to reduce hardness, improves machinability, improve mechanical tenacity, reduces crackle tendency, crystal grain thinning, and is to quench later
Fire is got ready.
The phosphorus content of hypereutectoid steel often beyond 0.77%, in this structure of steel the ratio of cementite more than 12%, so
In addition to pearlite is formed with ferrite, also unnecessary cementite, then the tissue of this kind of steel is pearlite+cementite.Cross common
Analysis steel generally first uses normalizing process after forging, eliminates net carbide.Then spheroidizing is carried out again, is mainly made in steel
Carbide spheroidization, obtain equally distributed spherical or granular carbide the tissue on ferrite matrix.
