A method of determination of deformation along a first direction of an equipment () in contact with hot material and including an inner face () in contact with the hot material and an outer face () opposite to the inner face () is provided. An equipment () in contact with hot material provided with means to determine its deformation along a first direction is also provided.

Method for determining deformation, and associated equipment comprising a plurality of corresponding wavelength couples each including a determined wavelength and a corresponding Bragg wavelength

A process for recycling blast furnace gas is provided. At least one portion of the gases resulting from the blast furnace undergo a COpurification step to create a CO-rich gas which is reinjected at a first top injection point at a temperature between 700&#xb0; C. and 1000&#xb0; C. through a top injection line, and at a second bottom injection point at a temperature between 1000&#xb0; C. and 1300&#xb0; C. through a bottom injection line. The gases from the bottom and top injection lines are heated at a temperature between 1000&#xb0; C. and 1300&#xb0; C. A portion of the CO-rich gas exiting the purification step is directly introduced into the top injection line via a cold gas injection line to obtain a temperature between 700&#xb0; C. and 1000&#xb0; C. at the first top injection point. The gas that flows through the bottom and top injection points controlled upstream of the system of the heaters. A device is also provided.
