Introduction
Interpretation of the National Standard of the People's Republic of China GB/T 29514—2018 Technical Specification for Steel Slag Treatment Process
1. Analysis of standard formulation background and technological evolution
GB/T 29514—2018 "Technical Specification for Steel Slag Treatment Process" is a revision of the original standard GB/T 29514—2013. The main updates include:
- Improved environmental protection requirements, especially noise and dust emission control;
- Added tank-type hot stuffing technology to enrich the treatment process;
- Optimized water use requirements and recycling specifications.
2. Standard framework comparison table (3+ dimensions)
| Dimensions | GB/T 29514—2013 | GB/T 29514—2018 (new/optimized) |
|---|---|---|
| Environmental protection requirements | Basic requirements, no detailed specifications | New noise control (GB12348) and dust emission requirements |
| Treatment process | Including pool-type hot stuffing and drum process | New tank-type hot stuffing technology, optimized water quenching process |
| Circulating water | Require recycling | Explicitly prohibit external discharge and standardize the design of water supply system |
3. Implementation suggestions and best practices
Optimization of environmental protection measures:
- Establish a complete circulating water system to ensure that the water quality and pressure meet the requirements;
- Equip dust removal equipment to control dust emission concentration;
- Implement waste heat recovery and utilization to reduce energy consumption.
Process selection:
- Select a suitable treatment process based on the characteristics of slag (e.g., drum process is suitable for high-temperature slag);
- Give priority to tank-type hot stuffy technology to improve treatment efficiency.
