Q690D carbon steel plate sheet, Q690CF steel plate, also known as CF (CrackFree) steel in the world, is a kind of steel with low carbon equivalent, low PCM value and excellent welding function. It is generally believed that there is no crack in welding without preheating or under low preheating conditions. In order to further improve Q690CF steel strength, TMCP and microalloying skills are also required.

Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This Q690D carbon steel plate sheet rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.
