Preliminary analysis on BOF shell’s deformation and treatment;

Effect of thermal-stress on creep deformation of BOF shell;

Strength analysis of spring-board coupling device between BOF shell and backing ring with FEM

This paper introduced development and processing plan of special steel plate for MeiShan Steel Plant s 150 t reformed converter,and carried out qualification on mechanical performance of special steel plate, which give a reference to the designation and study special steel plate of the converter vessel.

According to the arrangement characteristics of air-jet cooling structure of converter shell, the governing equations and boundary conditions describing air-jet cooling and heat exchange of converter shell were established and used to solve them by a method of conduction and convection heat transfer coupling numerical simulation with software FLUENT.

Test and analysis of N0.2 BF shell at Baogang;

Application of electroslag welding in welding of 5~# ,6~# blast furnace shell;

The structural stability of shell of blast furnace was studied,and the simple method of estimating the critical force by Walimier formula was propose,by which the critical load in the stalk direction was calculated for No.
