Laser measurement of CCM mould tube

Copper mould tube is a foundamental part of steel casting process. It’s internal geometry is a key factor for a good product quality and plant productivity. Sideralpha Sistemi provides instruments for mould tube geometry check-up. In this article we show the benefits of mould tube laser scanning.

Introduction to mould tube dimensional check

The required high quality of the steel and the increased casting speed need an accurate, frequent and easy check of the mould dimension and his shape. Perform such control in manual way is very expensive, inaccurate and requires too much time. The methodical check of the mould geometry produce immediately the following advantages:
  • Prevents quality defects
  • Prevents Break Outs
  • Optimize the mould life
  • Reduce the Mould costs
  • Reduce the maintenance cost
  • Optimize the Plant Productivity

So, who should be interested in mould tube dimensional check?
  • Copper mould tube manufacturers: quality check and certification of new manufacturer mould tube
  • Continuous casting machine suppliers: maintenance and assistance operations on managed CCM plants
  • Steel makers: Monitoring of used mould tubes or quality check of new tubes

Sideralpha Sistemi, following his long experience and know how in mould measurement, has developed some Mould Measurer in order to make such operation more easy accurate and economic.

Benefits of mould tube laser scansion

The state of the art in mould measurement has moved from mechanical contact probes to laser technology. The most important benefit is the contact-less and 360 degrees measurement. The full scansion of moud tube internal geometry allows a complete check-up of the tubes, not only the taper profile. Some controls are specific to the mould tube shape (ex. ovalization for round tube). In the following table all the available quality controls are shown:

deformations of mould tube

The mould laser scanner provided by Sideralpha are designed to check all these deformations in copper mould tube. The checks are executed according with mould drawing and selected tolerances. All the measurement results are summarize on a measurement report like this:
