OPENING OF PASSAGES
OPENING OF METAL PASSAGES
The care of the metal passage is essential to ensure the good operation of a melting furnace. Both in the case of small diameter passages (less than 3″), as well as in the case of refrigerated passages, the precision of the thermal lance to be used is fundamental, where ensuring a smooth and rapid opening speeds up the general operation and avoids the need for repass during the evacuation of the material and contributes to the task of covering the passage once necessary.
Trefimet thermal lances have a wide range of models, which are designed to adapt to any oxygen condition and to passages with different dimensions (diameter and length), so that Trefimet can always offer its customers the ideal product for their needs. operation.
SLAG PASSAGE OPENING
The opening of slag passages can present various difficulties. The materials that are evacuated through this passage generally have a higher viscosity than metal and therefore, the opening operations require a greater effort on the part of the operators. For this, there are lance models designed for larger diameter openings, where they allow operators to work in a straight line without the need to make repetitive movements to achieve an adequate opening diameter for slag evacuation.

OPENING OF REFINE PASSAGES
Generally, the opening of refining passages presents difficulties due to their layout. It is at this point that it is necessary to ensure a quick and precise opening. For this, Trefimet has high precision and powerful lances, with which it is possible to ensure even drilling, which facilitates the subsequent covering of the passage, ensuring that no cold material remains in it and future operations are not hindered.
