Description
Technical field
The present invention relates to pour into a mould melted material, enter a kind of method and apparatus that a casting die is used such as motlten metal.More precisely, the method and apparatus used of the cast anode that the present invention relates in electrolytic refining, to use.
Background technology
Cast and accurate supply that casting die is controlled are being important aspect the casting of metal anode for example, in the production of these metals, subsequent process steps after the metal anode casting is an electrolytic refining, wherein in order to reach high negative electrode quality and high efficient, require with other, a prerequisite is to have a uniform quality for shape and weight.In most of known methods, anode is cast in open-top mold.
At anode, during such as the casting of copper anode, fused solution is directed for example medial launder along an inclined chute to Casting Equipment from anode furnace, and motlten metal continues to be poured into pouring basin from here.The capacity of medial launder is significantly greater than the capacity of pouring basin itself, and it is also as deposit in the middle of the balance between anode furnace and pouring basin.When the beginning in cast stage, prepare the amount of metal of introducing in contained amount of metal is slightly larger than every batch in the pouring basin in the casting die.Usually, the amount of metal of preparing to be poured into pouring basin is the twice of the amount of metal of preparing to be poured into casting die.Motlten metal accurately is inducted into the casting die of unlatching by pouring basin.Pouring basin is emptying fully, but a so-called copper base is retained in the bottom.Modern anode casting is realized with an automation process in so-called casting platform.Wherein casting die is offset to the front of pouring basin on a round casting platform.When pouring into a mould by pouring basin, the control of supply be by the track of pouring basin and translational speed with and the monitoring of weight realize.Typically, the melt quantity of preparing to be poured in the casting die of a copper anode is introduced with precision 3%.Usually, anode weight is in the 300-600kg scope.
In order accurately to control the quantity delivered of the melt of preparing cast, pouring basin is provided with weight sensor.Cast is the control of automation ground, and cast beginning when pouring basin filling melt.The minimum weight of pouring basin is measured, and casting die is placed on the front of pouring basin.In casting process, pouring basin tilts, thereby motlten metal being flowed cross the pouring basin outlet enters casting die.When the weight of pouring basin was reduced to the target weighing quantity of the anode of preparing casting, cast stopped.Pouring basin is back to the starting position that preparation refills subsequently.
In anode casting process, hundreds of anodes are sequentially cast usually.When casting process finished, pouring basin typically kept added metal, and this metal allows to solidify in pouring basin.Pouring basin stands necessary maintenance procedure, and these programs often comprise the renewal of the whole liner of pouring basin.The invention enables can be with pouring basin emptying metal fully, and in such cases, pouring basin requires less maintenance operation.
The anode that in the electrolytic refining of metal, uses be shaped as slab, its thickness is about 30-100mm.The height of anode is about 900-1,500mm, with and width be about 700-1,200mm.In electrolytic cell, battery lead plate hangs with the carriage of a upright position by projection, is formed on the so-called lug of battery lead plate top edge, and groove edge is withstood in supporting.The anode lug is made by anode metal, and is often relevant with casting process.Therefore, an anode casting mould has a flat slot, i.e. cavity, and it has the shape of anode cross section, and slightly darker than anode thickness.
