Abstract
Official abstract text for this publication.
The invention relates to a method for manufacturing a melt launder to be used for transferring molten phase such as slag, matte, or metal formed in a process for the production of metals. The invention also relates to a melt launder to be used for transferring molten phase such as slag, matte, or metal formed in a process for the production of metals. The melt launder comprises a launder body of metal, a flow channel for molten phase, a refractory lining for lining the launder body of metal so that the refractory lining at least partly forms a flow surface for molten phase in the flow channel for molten phase, and a layer of steel between the launder body of metal and the refractory lining.
First claim
Opening claim text (preview).
The invention claimed is: 1. A melt launder, wherein the melt launder comprises a launder body of metal, a flow channel for molten phase, and a refractory lining for lining the launder body of metal so that the refractory lining at least partly forms a flow surface for molten phase in the flow channel, wherein the melt launder comprises a layer of stainless steel between the launder body of metal and the refractory lining, wherein the refractory lining being attached to the layer of stainless steel, wherein the layer of stainless steel being releasable attached to the launder body of metal, and wherein the layer of stainless steel has a first face that is in contact with the launder body of metal and an opposite second face that is in contact with the refractory lining. 2. The melt launder according to claim 1 , wherein the layer of stainless steel and the launder body of metal being provided with co-operating fasteners for releasable attaching the layer of stainless steel from the launder body of metal. 3. The melt launder according to claim 1 , wherein the launder body of metal being provided with cooling channels for circulating cooling medium in the launder body of metal. 4. The melt launder according to claim 1 , wherein the launder body of metal being at least partly made of copper or copper alloy. 5. The melt launder according to claim 1 , wherein the layer of stainless steel being provided with lifting means for lifting the layer of stainless steel from the launder body of metal to detach the layer of stainless steel to the launder body of metal. 6. The melt launder according to claim 1 , wherein the refractory lining comprising at least one of graphite, insulating refractory material, zirconium-oxide and carbon-based refractory material including carbon, semi-graphite, silicon carbide.
