High end raw material purification：adoptVacuum melting（VAR）+ electroslag remelting（ESR），Reduce sulfur in steel、phosphorus、Harmful elements such as hydrogen，Reduce inclusions and segregation，Used for wind turbine spindle 34CrNiMo6 Steel needs to undergo double vacuum smelting，impurity content≤0.005%。
Core heat treatment process：
quenching and tempering（quenching + High temperature tempering）：Optimal matching of strength and toughness，42CrMo Tensile strength after quenching and tempering≥1080MPa，yield strength≥930MPa，Widely used for shafts、gear。
Low temperature aging：Eliminate residual stress，Stable size，Prevent cracking during subsequent processing，If large wind turbine flanges need to be installed 200–250℃insulation 10–20 hour。
surface strengthening：induction hardening、carburizing / nitriding，Improve surface hardness and wear resistance，The surface hardness of gear forgings after carburizing reaches HRC58–62，Maintain resilience in the heart。
Intelligent detection standards：High end forgings need to go throughUltrasonic flaw detection（UT）、Magnetic Particle Inspection（MT）、X X-ray diffraction（residual stress），The accuracy of defect recognition reaches 99.2%，Ensure no internal cracks or inclusions。
