Abstract

Abstract:

The microstructure of H13 steel for cutter ring of tunnel boring machine was optimized by electroslag remelting, multi-directional forging and ultra-refining treatment. The optimized H13 steel was first subjected to conventional heat treatment to analyze the relationship between the hardness and impact toughness of the steel. According to this, the H13 steel cutter ring was subjected to the elastic hardening heat treatment. The results show that after the elastic hardening heat treatment, the blade edge forms a tempered martensite microstructure and the hardness is increased to 59 HRC; but the blade seat forms a tempered martensite microstructure, the hardness is reduced to 44 HRC, and the impact absorbed energy is increased to 23.5 J, achieving the combination of the high-hardness blade and the high-elasticity tool holder, which makes the cutter ring have the elastic characteristics of contraction and rebound and significantly improve the service life and rock breaking efficiency of the cutter ring.

Key words: H13 steel, ring blade, heat treatment, microstructure, mechanical properties
