The invention relates to a method for cooling a lance provided for converting a medium into a molten mass and/or for measuring the properties of the molten mass. A gas/liquid mixture is fed as a cooling medium into a cooling circuit which is closed up to the lance end (2) situated on the melting side. The invention provides that the gas/liquid mixture or the components thereof is/are fed and permitted to expand under pressure up to the area of the lance end (2) situated on the melting side. The invention also relates to a lance which has a mixing chamber (5, 6) connected to the cooling circuit. The mixing chamber has the connections (3, 7) for a gas and liquid supply which is designed to produce the gas/liquid mixture, whereby the mixing chamber (5, 6) is connected via a pressure line (10) to at least one two-component nozzle (11) arranged in the area of the lance end (2) which is situated on the melting side.

A vertical coil winder, for winding hot rolled products, comprises a reel (10) which has a structure formed by a substantially cylindrical container (11), and a plurality of vertical rods (13) is provided within said container, whereby a gap is defined between said container (11) and said rods (13) wherein a hot rolled product (38) is placed and wound thanks to the rotation of said reel. According to the invention, said plurality of rods (13) can move in the radial direction between an expanded position for winding said product (38) and a withdrawn position for extracting the finished coil (39).

It is provided a device (2) for positioning vitreous sheets (3) at a moulding station (4) in plants (1) for manufacturing glass panels, in which feeding means (8) moves a sheet (3) coming out of a furnace (5) in a first substantially horizontal direction (9) to bring it to the moulding station (4). A perimetric support element (13) associated with the support structure (7) of the device and arranged to cooperate with a moulding die to give the sheet the desired configuration receives the vitreous sheet (3), and actuator means (14) moves the feeding means (8) and the perimetric element (13) relative to each other along a vertical direction (15) to enable cooperation between the perimetric element (13) and the die for moulding of the vitreous sheet itself.

It is provided a level control apparatus for a liquid-state material in smelting furnaces and the like, in particular furnaces for rock wool processing, comprising at least one pipeline (7) extending externally of the furnace and having an end portion (7a) fitted in a furnace wall at a lower height than a desired constant level (6) of the liquid-state material and an upper stretch (7b) defining a weir sill (7c) disposed at the height of the constant level (6).
摘要:
The present invention relates to an apparatus for packaging compressible fibrous materials in the form of a roll, comprising at least one conveyor belt (2) having a corresponding operating stretch (4a) over which the compressible fibrous material (5) to be rolled up is placed. A deflection belt (3) cooperates with the conveyor belt (2) and defines a solid angle (Y) therewith, inside which angle a roller (6) operates in order to form a rolling-up space (7). A precompression device (12) acting upstream of the rolling-up space (7) relative to the feeding direction is active on the fibrous material for causing a predetermined compression of the material before said material reaches the rolling-up space (7).
