It is the solidification process where the liquid steel is poured into a bottomless mold with the shape of the cross-section of the semi-finished product to be manufactured. It is called continuous because the liquid steel never stops in the mold, so that you get continuous as-cast products without stopping the line. The main advantages…
DetailsCritical process in steel. Depending on the cooling speed, the microstructure of steel is changed. The influence of cooling will depend on the chemical composition of the steel, which will determin its hardenability. Depending on the cooling speed, the non-equilibrium transformations occur in steel: pearlite, bainite and martensitic.
DetailsIt can be added voluntarily or involuntarily to the steel by being present in the scrap metal. Copper increases tensile strength and yield strength in steel. It can be detrimental to the plasticity of the steel due to the appearance of fissures or cracks caused by the appearance of copper phases in the steel matrix.…
DetailsIt is the deterioration of a metal with loss of properties because of its interaction with the surrounding environment. It is produced by the loss of material on the surface of a piece by chemical action with exchange of electrons between two chemical species (electrochemical phenomenon). Corrosion may occur by chemical oxidation-reduction reaction or by…
DetailsIt is an axis with elbows and counterweights that takes the energy of the combustion of the cylinders. The energy is linear and it is converted into an alternating rectilinear motion in uniform circular motion. The crankshaft is placed in the central part of the engine and gives power to it.
DetailsIt is the ability of a material to be sheared. All steels are shearable under as-rolled conditions, except in abnormal circumstances where it may be necessary to provide them under treated conditions (annealing) to improve their shear condition, so that there is no excessive cracking or deformations in the cutting area.
DetailsThis loss of carbon has great influence by the loss of surface hardness in steel, especially after quenching treatments. Finding decarburized zones occasionally can produce surface defect, by the heterogeneous behaviour of the surface in forming processes.
DetailsIn long products, it is the deformation perpendicular to its axial axis and indicates the lack of straightness of the product. The more curvature a bar presents, the greater is its deflection. The deflection can be generated by the effect of a constant and non-uniform load of bars or by incorrect handling and positioning that…
