Definitions

  • This invention relates to furnace doors and in particular to the close sealing of the furnace opening thereby.
  • the present invention provides a furnace door for use in closing a furnace opening having a predetermined size and shape, which furnace door has a substantially heat resistant surface having an extent corresponding to at least the exent of said opening, characterized in that said door is provided with a flexible heat resistant ceramic fibre sealing means arranged for sealing engagement, in use, with the furnace around said opening.
  • sealing means is of a flexible ceramic fibre material.
  • ceramic fibre material is covered with ceramic fibre material though other heat resistant surface protecting materials may also be used here.
  • Each of the guide rods 5 is supported by three spaced apart outwardly extending vertically aligned levers 6 which are pivotally mounted 7 on lugs 8 which project forwardly from the furnace 1 to either side of the opening 3.
  • Each of the guide rods 5 is secured to first, innermost, ends 9 of each of the respective levers 6.
  • the second, outermost, ends 10 of the respective levers 6 are also interconnected by respective link members 11 which extend parallel to the guide rods 5 and pivotal axes of the levers 6 so that the latter move in unison.
  • the central lever 6' on each side extends 12 at its outermost end 10 beyond the outer ends of the other levers 6 and the axis of the link member 11 and is pivotally connected 13 to the piston rod 14 of a pneumatically operated piston and cylinder door closing means 15.
  • the ceramic fibre door seal means used in accordance with the invention is a known material used at present for lining the interior of furnaces. In general it is in the form of a more or less densely packed arrangement of upstanding ceramic fibres on a flexicle backing of for example a heat resistant cloth which may be cemented to the furnace door or directly or indirectly on a more or less rigid heat resistant substrate which may be conveniently bolted to the furnace door.
  • This type of material is commercially available from Messrs. C linotherm Ltd. of Dewsbury, Yorkshire, England and is made in various thicknesses e.g. from 40 to 125mm and various temperature grades e.g. heat resistant up to 1100°C and heat resistant up to 1500°C.
