摘要:
The present disclosure is directed to a method of converting green particles to form finished particles. The apparatus used for sintering incorporates an elongated hollow tube (12), an insulative sleeve there about to define an elevated temperature zone, and a microwave generator (22) coupled through a wave guide into a microwave cavity incorporated the tube. The particles are moved through the tube at a controlled rate to assure adequate exposure to the microwave radiation. A second embodiment sinters a solid part in a cavity or mold.

摘要:
Dispositif destiné à assurer l'introduction latérale de produits sidérurgiques, tels que notamment des billettes, directement dans la zone de chauffe d'un four, notamment d'un four de réchauffage, auquel lesdits produits sidérurgiques sont amenés par un moyen de manutention de type connu, ce dispositif étant caractérisé en ce qu'il comporte une goulotte (14) sur laquelle le produit (10) est déposé par le moyen de manutention, avant l'introduction latérale dans le four, cette goulotte servant de support audit produit lors de l'introduction dans le four et étant munie à cet effet de moyens de déplacement (40-46) pour assurer son enfournement en même temps que le produit qu'elle supporte, des moyens (48) étant en outre prévus pour assurer la dépose dudit produit dans le four à partir de ladite goulotte.
摘要:
Plant (10) for rolling long products from billets and blooms (30) coming from at least two continuous casting lines (11), each of said at least two lines (11) being provided with a shears (12), said plant comprising a temperature-equalizing furnace (16) disposed downstream of said shears (12) and containing an intake roller conveyor (17) for each of said at least two continuous casting lines (11), a discharge conveyor (18) disposed in an intermediate position between said at least two lines (11), and transversely-moving conveyors (21,26) for transferring said billets or blooms (30) from said intake conveyors (17) to said discharge conveyor (18), said temperature-equalizing furnace (16) further comprising fixed supports (19) located between said intake roller conveyors (17) and said discharge conveyor (18), said fixed supports (19) defining a zone of equalization of the temperature of said blooms and billets (30), and at least some (25) of the rollers belonging to said intake roller conveyor (17) being vertically and transversely displaceable for constituting said discharge conveyor (18).
摘要:
Furnace with refractory longitudinal members and with central charging for heating and storing hot products, whereby the central charge arrives from a continuous casting plant or from previous hot processes, the furnace (10) comprising a first furnace portion (10a) for the introduction of a cold charge (12) and for storage and also a second furnace portion (10b) for discharge of the heated charge (15), the first (10a) and second (10b) furnace portions comprising stationary longitudinal members (23) and movable longitudinal members (24), the central charging taking place between the first (10a) and second (10b) furnace portions, a central intake and guide channel (22) being defined as a furnace bed by the plurality of stationary longitudinal members (23) cooperating with the respective plurality of movable longitudinal members (24a-24b) of the first (10a) and second (10b) furnace portions, the movable longitudinal members (24a-24b) in their raised position substantially facing each other, the width of the central intake and guide channel (22) and possibly the height of the movable longitudinal members (24) depending on the cross section of the hot product (26) being charged.
摘要:
Um eine Speicherkapazität zwischen Stranggießanlage und Walzgerüst zu schaffen, wird zwischen Einfördervorrichtung und Ausfördervorrichtung eines Wärmofens ein Speicherofen (10) vorgesehen, der mit Querschleppern ausgerüstet ist, wobei in diesem Speicherofen Vorbänder (14) gelagert werden können oder bei störungsfreiem Verlauf zwischen Stranggießanlage und Walzgerüst schnell durchgefördert werden können.
摘要:
The furnace comprises a tubular inner chamber for the treatment of the raw material, mounted inside the enveloping body of the furnace which is insulated from the exterior and is provided with internal resistor systems for heating the chamber of the furnace by radiation, comprising means for feeding raw material at one end and means for controlling the output of completed product at the other end of the treatment chamber of the furnace, inside which a worm screw, driven in rotation from the exterior, is mounted rotatably, respective percussion devices being incorporated in the ends of the screw to prevent compaction of the mass on the screw.
