Design of new welding processes for iron and steel industry equipment manufactured in Creusabro® and subject to highly abrasive conditions

The current trends involve designing diffusers used in blast furnaces using Creusabro® 4800 materials, mainly as a result of their high resistance to wear and abrasion. This is a new material in the iron and steel industry, since the materials used until now (mainly low-hardness ferrite type carbon steel) did not solve the problems associated with the wear to which equipment was subject.

DF Operaciones y Montajes considers that welding joints must be designed for CREUSABRO® materials without the application of PWHT, which will reduce the work execution and operation times and, as a result, the associated costs. The purpose of this is to acquire the know-how required to be competitive in manufacturing and assembling and installing this type of material.
