摘要： An apparatus for displacing a portion of a dross layer enclosed within an introducer sheath of a dip tank includes a gas source and a gas distributor. The gas distributor is in communication with the gas source via a gas line. The gas distributor includes one or more gas outlets or a gas emitter. The gas distributor is configured to direct a flow of gas towards the dross layer at an angle to move the portion of the dross layer away from a predetermined point.

摘要： A metal fume reduction apparatus for a snout disposed between an outlet of a heat treatment furnace and a molten metal plating tank, includes: a main pipe part; an introduction pipe part and a return pipe part each of which is configured to couple the snout to the main pipe part so that an interior space of the snout communicates with the main pipe part; and a cooling part configured to cool a cooling target site, of the main pipe part, located between a first connection portion with the introduction pipe part and a second connection portion with the return pipe part in a longitudinal direction of the main pipe part. The cooling target site is located below the first connection portion of the main pipe part in a state where the main pipe part is coupled to the snout via the introduction pipe part and the return pipe part.

摘要： Provided is a continuous hot-dip galvanizing apparatus comprising: a vertical annealing furnace having heating, soaking zone, and cooling zones therein; and a hot-dip galvanizing line downstream of the cooling zone. The heating, soaking, and cooling zones each have, in its upper portion, at least one upper hearth roll and, in its lower portion, at least one lower hearth roll. The soaking zone has a first and second humidified gas supply ports to supply a humidified gas having a dew point of 10° C. to 30° C. to the soaking zone. The first and second humidified gas supply ports are 1.0 m to 5.0 m lower than the center of the lower and upper hearth rolls, respectively, and overlap the steel sheet. The first humidified gas supply port is provided only for an ascending pass and the second humidified gas supply port is provided only for a descending pass.

摘要： A continuous coating line includes a snout assembly exposed to molten metal. The snout assembly includes a snout tip positioned about a steel strip that is immersible in the molten metal to provide a seal around the steel strip during entry into the molten metal. The snout tip includes a refractory material that is resistant to wear, abrasion, and corrosion when the snout tip is exposed to the molten metal.

摘要： A method for rinsing an overflow chamber at the bath-side end of a snout of a device for hot-dip coating a metal strip is presented. The snout guides the metal strip in a protective gas atmosphere before the metal strip is coated with a metal melt. A rinsing cycle is carried out in the overflow chamber of the snout by feeding metal melt from the molten bath into the overflow chamber and at the same time, sucking and pumping said melt out of the overflow chamber back into the molten bath. This rinsing cycle can be performed even when the snout has been retracted from the melt by supplying the melt from the molten bath to the overflow chamber with a delivery pump.
