From SAW principles to physical anti-collision coding — the three pillars behind reliable EMMA-ID recognition in hot, dusty and metal-dense environments.
The next-generation SHT1822-350 Pro tag delivers maintenance-free long-term operation at 450℃, with upgraded chip packaging and mounting design, fully compatible with existing EMMA-ID readers, and has been piloted at several steel plants with recognition accuracy above 99.9%.
At the expo, Mianrui exhibited its full EMMA-ID product line — tags, radar readers and high-temperature antennas — together with a full-life digital control solution for copper slag cooling yards, drawing representatives from steel plants and design institutes.
Since mass installation in 2019, the EMMA tag system on 39 ladles at Baosteel Shanghai No.1 steelmaking has run stably, proving high-temperature ID reliability in "one-click steelmaking".
The solution covers 12+ AI models across converter and LF refining, enabling an "operator + digital worker" combination for autonomous, cost-efficient steelmaking.
On the automatic high-temperature test platform, EMMA tag chip samples work stably for long periods at 450℃.
For truck-transported hot metal, EMMA tag recognition covers all plant ladles with 99.7% tracking accuracy.
High-temperature EMMA tags build the digital foundation of the slag cooling yard: smart bucket tracking, cooling control and dispatch.
Comparing three ladle-ID technologies across working temperature, read range, lifespan, accuracy and maintenance.
