《GB/T 6983-2022电磁纯铁》由TC183（全国钢标准化技术委员会）归口，TC183SC10（全国钢标准化技术委员会特殊合金分会）执行，主管部门为中国钢铁工业协会。
Introduction
Analysis of the core content of the standard
Key updated content: The new version of the standard deletes the requirements for 5 types of billets such as continuous casting billets, and adds vacuum refining processing specifications
Electromagnetic performance grading system
| Performance level | Coercive force value (A/m) | Aging value-added range | Applicable scenarios |
|---|---|---|---|
| DT4AAdvanced | ≤8.0 | Ordinary type 50h aging | Medium frequency electromagnetic core |
| DT4ESpecial Grade | ≤4.8 | Special Heat Treatment | High Precision Sensor |
Key Points of Quality Control
- Hardness Value Specification:The Vickers hardness of annealed cold-rolled sheet must be controlled within the range of 85-140HV5
- Special grade sheet must meet the B1000 magnetic induction intensity ≥1.53T
- Newly added Type Inspection clauses to deal with raw material process change scenarios
Implementation and Application Suggestions
Metallurgical process control: During vacuum refining, the degassing rate should be monitored to be ≥85% and the C content should be ensured to be ≤0.006%
Demonstration project: The coercive force of a UHV transformer was reduced by 18.7% after the use of DT4C material
