Abstract
All of a cast-iron or cast-copper stave cooler's weight is supported inside a furnace containment shell by single gas-tight steel collar on the backside. All the coolant piping in each cooler has every external connection collected and routed together through the one steel collar. A wear protection barrier is disposed on the hot face. Such is limited to include at least one of horizontal rows of ribs and channels that retain metal inserts or refractory bricks, or pockets that assist in the retention of castable cement and/or accretions frozen in place from a melt, or an application of an area of hardfacing that is welded on in bead, crosshatch, or weave pattern.
Claims5
A single-mounting stave cooler for use in a furnace, comprising:
- a cast iron stave body in which are cast but not bonded any liquid coolant steel piping wherein, such absence of bonding prevents cracks in the cast iron stave body from propagating through into the liquid coolant steel piping;
- a single protrusion and jacketing steel-to-steel welding collar with a proximal end embedded, or otherwise anchored into a backside of the cast iron stave body, and positioned to enable the stave cooler to hang on and be entirely supported by a distal end passed from only inside and through a single gas-sealable penetration of a steel containment shell, and in which all external piping connections of the liquid coolant steel piping within are collected together as a single group and routed through and passing between the proximal and distal ends of the single steel-to-steel welding collar;
- and
- a wear protection barrier disposed on a hot face of the cast iron stave body and that is limited to include at least one of pockets and/or horizontal rows of ribs and channels able to retain metal inserts or refractory bricks, or that assist in the retention of castable cement and/or accretions frozen in place from a melt.
A stave cooler that includes liquid coolant piping cast inside, comprising:
- a stave cooler body with a hot face and a backside and a liquid coolant piping cast between inside;
- at least one external connection of the liquid coolant piping into the stave cooler body;
- and
- a single gas-tight steel collar on the backside able to support an entire weight of the stave cooler, and through which all of the at least one external connections of the liquid coolant piping are collected and routed together;
- wherein, the stave cooler is limited to stave coolers that can mount only from an inside of a steel containment shell provided with a matching penetration to accommodate and seal by welding to the single gas-tight steel collar.
