    摘要： A tiltable ladle for molten metals, having a cover (11) and a suspension frame comprising two lifting arms (5, 6) rotatably connected to trunnions (7, 8) fixed to the outside wall of the ladle (1) and a horizontal beam (9) above the ladle equipped with a hook (10). The top of the ladle and the ladle cover are formed as segments of a cylinder, which have a common axis. The common axis of these cylinder segments may coincide with the pivotal axis of the ladle (1) or may be spaced from it. The cover (11) is affixed to the suspension frame.

    摘要： Method for producing castings from cast-iron containing structure-modifying additives. A sample from a bath of molten iron is permitted to solidify during 0.5 to 10 minutes. The temperature is recorded simultaneously by two temperature responsive means, one of which is placed in the centre of the sample and the other in the immediate vicinity of the vessel wall. The dispersion degree of the graphite phase is assessed in relation to known reference values by aid of recorded values of supercooling at the vessel wall, the recalescence at the vessel wall, the difference between the temperature at the vessel wall and at the centrum of the vessel and the derivative of the temperature decrease at the vessel wall during the time of constant eutectic growth temperature at the centre. When necessary a graphite nucleating agent is added to the molten bath or the dispersion is lowered by implementing a holding time prior to casting. The morphology of the graphite precipitation is also determined by aid of recorded values and possibly corrected by changing the amount of structure-modifying agents present.

    摘要： A process for the degassing, refining or filtering treatment of liquid metals or alloys wherein the metallic liquid is treated with a solid treatment agent. The process comprises the steps consisting of providing the treatment agent in the form of solid granules (10) in a closed container (1) having two counterposed walls in the shape of perforated diaphragms (2a, 2b), with holes having such dimensions as to retain said granules, and having further lateral walls; interposing said container in the pouring channel, at the base thereof; and passing said metallic liquid through said container through said diaphragms to make contact with said treatment agent in said container. An apparatus for performing the process is also described.

    摘要： A process for adding calcium to a bath (2) of molten ferrous material is disclosed in which a calcium metal-containing wire (1) is fed through a refractory lance (5) into the bath (2). Recirculatory stirring of the molten ferrous material is accomplished with an inert gas flow through the lance (5). The calcium-containing wire (1) is fed at such a rate that it substantially bends towards the horizontal direction after it leaves the lance (5) and melting of the calcium in the wire (1) occurs primarily in or directly below a region of downwelling of the molten ferrous material. Suitable wire feeding rates will depend upon the disposition of the lance (5) in the bath and the composition (e.g. clad or unclad) and cross-sectional dimensions of the calcium metal-containing wire (1). A preferred apparatus for adding processing elements in wire form directly into a molten material comprises a heat resistant nozzle (60) positionable relative to the surface of the molten material such that an inlet is disposed above the surface and an outlet (84) is disposed beneath the surface; a mechanism (24) for feeding the wire (20) through the nozzle (60) directly into the molten material; and a system (31, 33, 42) for injecting a substantially inert gaseous medium into the molten material together with the wire (20), whereby the inert gas substantially prevents closure of the nozzle (60) by solidified molten material and promotes mixture of the processing elements with the molten material through gas bubble agitation. The apparatus further comprises a substantially gas-tight conduit (44) connected to the nozzle inlet, through which the wire (20) and the inert gaseous medium are delivered to the nozzle (60). A pressure-driven seal (30) prevents atmospheric contamination and prevents loss of inert gas. Passing the wire (20) and gaseous medium through a bore in the nozzle (60) having an elongated, gradually tapered funnel-shaped section (80) adjacent the outlet (84) maximizes the effect of the inert gaseous medium.
