Backup rolls are the main tool in a four-high rolling mill; the rolling forces applied in load cells promote the fatigue of the material due to mechanical contact between backup rolls and work rolls. This work investigated the causes of recurrent failures in backup rolls, with cracking always initiated on the surface of the roll body and finishing...
Article
In the present study, an experimental analysis of the friction forces, speeds and friction coefficients that influence the size of the wear track in a steel exposed to mechanical contact was carried out, for this, steel blocks with an alloying element of. 5% Cr base and D2 steel standard ring, representing the Block-on-Disk method, according to the...

The present study presents the relationship of temperature and deformation as well as the analysis of heat transfer and deformation produced during welding of a steel plate. The method consists of strategically welding a base metal plate (A-36) with a high-hardness filler material to obtain an overall increment in wear resistance. However, the ther...

Samples of barite mineral ore, were ground to a mesh of 250, and then were subjected to a leaching stage with hydrochloric acid at different times, then; the leached barite mineral ore was subjected to a carbonation stage controlling different parameters such as pH, temperature, time and speed of agitation. Finally, it was subjected to a sintering...

The present work analyzes the influence of crown shape on the distribution of stresses and deformation for rolling processes. This study consists of a Finite Element Analysis considering combinations of crown shape for Back Up Roll and Work Roll, rolling forces, properties of materials and dimensions of rolls and strip. An analysis of the rolls bas...

The present study consists in analyzing the friction coefficient as a variable of the normal load and slip speed for 5 % Cr steel, by applying the Block-on-Disk method according to ASTM D2714. The friction coefficient increases linearly 23,25 % from 0,214 to 0,266 when the load is increased from 196 N to 392 N; the same phenomenon is observed when...

This work shows evidence of the implications of total additions of silicon, aluminium and chromium on low ductility during hot rolling in non-oriented electrical steels. This paper explains the reason of ductility loss at temperatures between 950 - 1000<sup>°</sup>C in electrical steels which exhibit higher Ar<sub>3</sub> transformation temperature...
