Technical Improvement and Development in the Medium and Heavy Plate Plant of Jinan Iron and Steel Group Corp;

Sectional multi-point forming and its numerical simulation of plates;

The Application of slab design for improving yield of plate;

Readjustment of composition of product mix and domination of plate market;

Research and Production on Medium and Heavy Plate of HQ590DB Ultra-Low Carbon Bainitic Steel;

Prediction Model for Rolling Force Parameters during Rolling of Medium and Heavy Plate;

Regression Analysis on Structure Property and Technology Parameter of Steel 16Mn Medium and Heavy Plate;

Flaws in the heavy and medium plate of different thickness detected by ultrasonic detector were studied.

This article briefly introduces the determination of the area of cooling bed and choice of the type of cooling bed for Heavy and medium plate .

By using TMCP measures of grain refining and deposition strengthening and adding microelement Nb,the mechancical behaviours were guaranted and coat was lowed in producing Q460C medium plate.

Data of medium plate mechanical properties,process parameters and chemical composition are analyzed to improve plate quality,to search process parameters of different steel and specification and forming expert system database,to supervise produce.
