An apparatus to move and preheat metal material (M) to be fed to a container comprises a containing structure, having an internal compartment and provided with a support wall, a conveyor for the material (M), a fume transit section whose volume reduces as it is distanced from said container along the longitudinal development of said containing structure, and a collector for hot fumes (F) whose volume increases in a manner correlated to said reduction in the fume transit section. The collector is located below said conveyor inside the internal compartment essentially along the entire longitudinal development of said containing structure. Moreover, one or more through apertures are made in said support wall to put the conveyor and the collector into fluidic connection.

Apparatus to move and preheat metal material

Vibration device for a conveying apparatus () to convey a metal charge in a longitudinal direction (X) comprising at least two vibration mechanisms () each disposed on opposite sides of the conveying apparatus () so as to feed the metal charge. The vibration mechanisms () comprise at least a first plurality of eccentric masses () having their mass barycenters (B) oriented in parallel directions to each other, and a second plurality of eccentric masses () having their mass barycenters (B) disposed angularly offset with respect to the disposition of the barycenters of the first plurality of eccentric masses ().

Bottom electrode or anode for continuous direct current arc furnaces, provided with a cooling system which allows to improve the effectiveness of the cooling action of the bottom electrode, made in the shape of bimetallic billet, for the purpose of ensuring a sufficient height of the portion of said electrode which remains solid during the operation of the furnace, also when there is a very high electric load.

Electrode for direct current continuous arc furnace

Crystallizer for continuous casting, having a monolithic tubular structure defined by lateral walls () in the thickness of which channels () are made in which a cooling liquid flows, wherein two adjacent lateral walls () define a corner or s edge zone. On at least one longitudinal portion (C) of at least one of the lateral walls () and/or of at least one of the corner zones, defining a zone in correspondence with which, during use, the meniscus of the liquid metal is located, a reduction in thickness () is made, starting from the external surface, determining a cross section with a reduced area with respect to the remaining longitudinal portions of the monolithic tubular structure.

Crystallizer for continuous casting

Crystallizer for continuous casting, having a monolithic structure defined by lateral walls in the thickness of which channels () are made in which a cooling liquid flows. The channels () are geometrically sized so as to define, in a zone substantially astride the meniscus (M), an increased transit speed of the cooling liquid, wherein by increased speed it is intended that in at least some of the cooling channels () the speed of transit of the cooling liquid is greater in the zone astride the meniscus (M) compared with a zone below or above said zone astride the meniscus (M).

Oscillating table for blooms or billets production plants, comprising pairs of bars, lying on at least one horizontal plane, which constitute the elastic support elements of the mold, thus permitting an optimal guidance of the oscillation thereof exclusively in the casting direction, said pairs of bars constituting a tie rod-strut system working in bending that confers to the table very high torsional and lateral stiffness. It allows a high precision in guiding mold thus consenting it wide oscillations in the axial casting direction only.

Oscillating table

Provided is a crystalliser holding device for billets, blooms and slabs production plants that has a high constructive simplicity, a significantly reduced overall weight and that reduces substantially to zero the need for maintenance. The crystalliser holding device of the invention, in addition to efficaciously guaranteeing the transfer toward the exterior of the heat of the liquid steel introduced into the tubular crystalliser contained therein, also provides a separate circuit for cooling the continuous ingot exiting the crystalliser and the rollers at the foot. It also permits an easy and rapid replacement in the oscillating table in which it is housed.
