Abstract：In order to improve the quality and economy of ZG35Cr24Ni8Si2N coke pot lining plate,by studying the working conditions and structural characteristics of the coke pot lining plate,the smelting process and the casting process of series vertical casting for the control alloy composition of the nitrogenous heat-resistant steel were developed,and the measures of adding“×”anti-deformation bars to the thin plate parts were taken,the size and performance of products could meet the requirements.The effects of annealing treatment and N content on the mechanical properties of single cast and bulk specimens were analyzed.The results show that the mechanical properties of the product can be guaranteed and the yield and pass rate can be improved by controlling the N content to the lower limit,pouring according to the described process and delivering the product as cast.
