Study on the process control of AH36 high strength ship plate

There are amounts of surplus in the performance of A36 high strength ship plate at present. The optimal control of smelting process and method of controlled rolling and controlled cooling parameters was used to in order to higher the efficiency on the basis of statistical analysis of production data of A36 high strength ship plate. The influence of the content of Nb reduced and the content of C and Mn controlled on the performance of A36 high strength ship plate was investigated. The result show that the content of Nd can reduced by the optimization of the composition A36 using the lower plate finishing rolling temperature and rolling red temperature limited witch is stability controlled at process parameters. The cost of A36 high strength ship plate is reduced and the performance can meet the requirements. (paper)
