Description

Technical Index

Item	Index
System precision	±5mm
Reproducibility	±5mm
Regional quick-measuring time	＜1min
Full graph measuring time	5-7min
Positioning time	＜30s
Maximum tolerable temperature of lining	1700℃

3D thickness graph of BOF lining

Functional Advantages

Quick measuring speed, regional measuring time is less than 1 minute, and the whole graph measuring time is less than 7 minutes.

Excellent performance of high-temperature protection, the closest detectable measuring distance is 2 meters away from the converter once tapping is finished.

Accurate and visible measuring result, system precision is ±5mm with 2D and 3D thickness graphs.

High density of scanning points, which reflects the thickness status of BOF lining precisely.

Convenient and swift measuring mode, it is automatic positioning and detection, and one-key operation.

Thorough safeguard functions, equipped with functions of automatic high temperature alert, low power remind, and fan cooling.

Multiple additional functions, equipped with functions of melting bath level prediction and tapping angle prediction.

System Significance

The occurrence of BOF molten steel leakage accident is prevented.

Reasonable guidance for lining repair is provided which improves the service life of lining.

The BOF melting bath level and tapping angle are predicable to optimize oxygen lance position, guide and optimize the BOF safeguard technological process of slag splashing, and guide the selection and dosage of lining gun-mix refractory.
