Abstract

The invention relates to a preparation method of a 12Cr2Mo1 hot-rolling container steel plate, and belongs to the technical field of a metallurgical material. The preparation method comprises the following steps: heating the hot-rolled steel plate to 900 to 940 DEG C, preserving heat for 30 to 50 minutes and performing heat-preserving treatment for the first time; and after performing heat-preserving treatment for the first time, cooling to 670 to 730 DEG C, preserving heat for 20 to 30 minutes, performing heat-preserving treatment for the second time and then cooling to a room temperature after performing heat-preserving treatment for the second time. The continuous heat treatment method is high in production efficiency.

Description

technical field The invention relates to a preparation method of a 12Cr2Mo1 hot-rolled container steel plate, belonging to the technical field of metallurgical materials. Background technique With the rapid development of petroleum, chemical and other industries, higher requirements are put forward for 12Cr2Mo1 hot-rolled container steel. 12Cr2Mo1 hot-rolled container steel has good structure and performance stability at medium and high temperature (375-595°C). At present, the heat treatment process of 12Cr2Mo1 hot-rolled container steel plate is normalizing + tempering, but the production efficiency of this method is low. Contents of the invention The present invention solves the above-mentioned problems by adopting a continuous heat treatment method. The invention provides a kind of preparation method of 12Cr2Mo1 hot-rolled container steel plate, and described preparation method is: Heat the hot-rolled steel plate to 900-940°C, keep it warm for 30-50 minutes, and p...
