Abstract
A wall of a mold assembly for the continuous casting of steel has a steel back-up plate. A thermally conductive plate composed of copper or a copper alloy is bolted to the back-up plate and a relatively thin copper or copper alloy facing is soldered to that surface of the thermally conductive plate which faces away from the back-up plate. The thermally conductive plate may be omitted and the facing soldered to the back-up plate. The facing contacts and cools a continuously cast strand travelling through the mold. When the facing becomes cracked or worn beyond repair, the solder joint is melted to remove the facing and a fresh facing is soldered to the thermally conductive plate or back-up plate.
Claims30
A wall for a continuous casting mold, comprising a carrier having at least one carrier element;
- a thermally conductive facing on said one carrier element adapted to contact and cool a continuously cast strand travelling through the mold;
- and a fusible connecting layer joining said facing to said one carrier element, said connecting layer including solder and having a melting point lower than the melting points of said one carrier element and said facing.
A wall for a continuous casting mold, comprising a carrier having at least one carrier element;
- a thermally conductive facing on said one carrier element adapted to contact and cool a continuously cast strand travelling through the mold, said carrier having a surface directed towards said facing, and said carrier being provided with a hole having a first portion which is open at said surface and a second portion extending from said first portion away from said surface;
- a fastening element having a shank and a head on said shank, said head being located in said first portion and said shank extending into said second portion;
- and a fusible connecting layer joining said facing to said one carrier element, said connecting layer having a melting point lower than the melting points of said one carrier element and said facing.
A method of making a mold, comprising the steps of sandwiching a fusible material between a carrier element and a thermally conductive facing for said carrier element, said material including solder and having a melting point lower than the melting points of said carrier element and said facing;
- and joining said facing to said carrier element, the joining step including melting said material to thereby form a connecting layer between said carrier element and said facing upon solidification of the molten material.
A method of making a mold, comprising the steps of sandwiching a fusible material between a carrier element and a thermally conductive facing for said carrier element, said material having a melting point lower than the melting points of said carrier element and said facing;
- joining said facing to said carrier element, the joining step including melting said material to thereby form a connecting layer between said carrier element and said facing upon solidification of the molten material;
- and removing said facing from said carrier element by melting said connecting layer.
A method of making a mold, comprising the steps of sandwiching a fusible material between a carrier element and a thermally conductive facing for said carrier element, said material having a melting point lower than the melting points of said carrier element and said facing, and said carrier element having a surface which is directed towards said facing;
- inserting a fastening element into said carrier element via said surface prior to the sandwiching step;
- and joining said facing to said carrier element, the joining step including melting said material to thereby form a connecting layer between said carrier element and said facing upon solidification of the molten material.
