Definitions

  • the invention relates to a device for coating band-shaped material, at which is a metal strip through a receiving the molten coating material Container is passed through the one below the melt pool level has band-shaped material enclosing channel in which by inductors in Coating material currents are induced which generate an electromagnetic force Cause retention of the covering material.
  • the channel be light is releasably attached to the bottom of the container and from several, in the direction of tape travel separable and mutually sealed parts that can be replaced of the channel individually with the band inside after loosening the separating connection are movable away from the tape in the direction of tape travel.
  • the essence of the present invention is the channel made of parts that can be separated from one another train that can be moved away from the belt to replace the channel, without the tape itself having to be cut or unthreaded. That's the channel or the parts of the channel are easily detachable at the bottom of the covering material Receiving container attached and can be in the shortest possible time after emptying be moved away from the container. In the same way, new channel parts be brought up and put together to form a new channel that there is a closed channel encompassing the band. The separable parts are sealed against each other by suitable sealants and seal the sewer liquid-tight in the working state.
  • these can be attached to the inductors and be movable or displaceable together with these. That means that at Replace the channel parts and open the closed channel Inductors, for example guided on rollers, can be moved across the belt and take the separate duct parts with you when moving.
  • the present invention enables the channel parts to be changed quickly without removing the belt beforehand and reducing the downtimes of the system considerably. This can increase the productivity of the system, while at the same time the quality of the coated metal strip is increased because of the facilitated Quick change of the worn channel parts by changing the channel caused coating irregularities are kept very low.
  • 1 denotes the container that holds the molten coating material 2 takes in.
  • the band marked 3 is in the direction of the arrow from bottom to bottom passed through the top of the container 1 and thereby with the coating material 2 coated.
  • a fastening device 5 for the Parts 6a and 6b of the channel designated 7 through which the band 3 is centered.
  • the rollers 8a, 8b in the entrance area of the Channel 7 created a stable guide for the tape 3, through which the tape 3 in in a center-centered location.
  • the inductors are on both sides of channel 7 9a, 9b arranged, which - as can be seen in the dash-dotted representation - on rollers 10, which in turn roll on guideways 11, on both sides of channel 7 are movable away.
  • FIG. 2 the same parts are labeled identically, the channel of rectangular cross-section, the cross-sectional opening depending on the thickness and width of the tapes 3 to be coated.
  • the channel shown in cross section is off composed at least two parts 6a, 6b ( Figure 3a) by suitable heat-resistant seals 12 together to form a closed channel 7 are connected.
  • the channel consists of four parts, namely the broad sides 6a, 6b and the end faces 6c, 6d which seal the broad sides and which are in turn sealed off from the broadsides at 12.
  • the channel consists of two separable parts, each L-shaped are formed, the one leg of the L-shaped cross section opposite the other leg forms the end wall of the channel and both legs at 12 are sealed against each other.
  • the advantage of the present invention is that it consists of two or more parts composite channel 7 when replacing the channel no separation in the System located metal strip required and accordingly Plant availability is increased.
  • the channel By forming the channel from two or several parts that are separable in the direction of the tape, the disassembly of the Channel with tape located therein, with quick connectors the conversion can be carried out in the shortest possible time. Between Suitable sealing elements or materials are inserted into the duct parts Prevent liquid metal from flowing out during operation.
  • the channel 7 can advantageously be heated via the inductors if after the conversion of the channel, this must be prepared for a new work cycle.
