Forming fine dispersed inclusions in steel can significantly improve the toughness of the heat affected zone deteriorated by high heat input welding. In prior studies, very few authors have investigated high heat input welding steel with a holistic perspective (from production to application). Therefore, for a better understanding of the production process, this paper tackles the effect of Zr on microstructures and mechanical properties after continuous casting, rolling, and welding. It is found that Zr (34 ppm) can effectively increase the number of inclusions in EH36 slab and plate, refining the microstructure and improving the mechanical properties of steel. However, after the high heat input welding thermal simulation experiment, such content of Zr is not able to inhibit austenite grain growth, or promote the nucleation of intragranular ferrite. It is further suggested that the effects of the contents of O and Zr on the forming of inclusions should be investigated.
