Abstract
The invention relates to a method for adding alloy elements in up-drawing copper-magnesium alloy casting. The method is characterized by including: calculating adding quantity, to be more specific, calculating the magnesium ingot weight which needs to be added when every electrolysis copper plate is added according to the weight of each batch of electrolysis copper plates and the empirical value of magnesium utilization rate; crushing a magnesium ingot, to be more specific, using a special hydraulic shear to cut the whole magnesium ingot into small pieces so as to precisely weigh magnesium of appropriate weight in the next step; weighing the magnesium ingot, to be specific, weighing the whole magnesium ingot and the magnesium ingot pieces on an electronic scale with the minimum measuring unit being 1g so as to obtain the magnesium ingot weight which needs to be matched with each electrolysis copper plate; packaging the magnesium ingot; charging. By the method, magnesium element utilization rate is increased, the risk that impurities are mixed into melted copper is reduced, and product quality is increased.
Description
Technical field
The present invention relates to a kind of be applied to draw copper-magnesium alloy strand produce alloying element addition means.
Background technology
Because magnesium belongs to Strong oxdiative element, and fusing point is low, density is little, and copper-magnesium alloy very easily reacts with oxygen and forms hard crisp phase in fusion process, reduces the mechanical property of rod of metal alloy.Magnesium elements also has corrosive nature to furnace lining material simultaneously.Therefore, in copper-magnesium alloy castingprocesses, the scaling loss amount of magnesium must be lowered as possible, reduce the content of hard crisp phase in strand.Traditional magnesium elements additive process, such as, add copper magnesium master alloy, and the Mg content in this alloy cannot be accomplished roughly even, and cost is too high.Again such as, pure magnesium is added directly into stove, because magnesium density is low, easily floats, its scaling loss amount can be caused to increase, cause waste.In stove, the oxide compound of magnesium increases simultaneously, and namely the quantity of slag increases, and the frequency of workman's scarfing cinder improves, labour intensity strengthens, inevitably to the disturbance of copper water in slag too much in addition and scarfing cinder process, increase the risk that dreg defect appears in product, remote effect quality product.
Summary of the invention
The object of the present invention is to provide a kind of up-drawing method copper-magnesium alloy casting alloy element addition means, reduce the scaling loss of alloying element magnesium, thus reach the effect of saving material and improving slab quality.
A kind of up-drawing method copper-magnesium alloy casting alloy element addition means, is characterized in that: comprise calculating addition → magnesium ingot fragmentation → magnesium ingot weighing → magnesium ingot to pack → reinforced, five operation stepss; Calculating addition step is the weight that basis often criticizes electrolytic copper plate, and the empirical value of magnesium utilization efficiency, calculates the magnesium ingot weight of often adding one piece of electrolytic copper plate and needing collocation to add; Magnesium ingot destruction step uses dedicated hydraulic to cut, and the magnesium ingot of monoblock is cut into fritter, can go out the magnesium of approrpiate wts by accurate weighing in next step; It is that the fritter magnesium ingot that monoblock magnesium ingot and upper step cut out to be placed in minimum division value be that the electronic scales of 1 gram weighs that magnesium ingot weighs step, weighs up the magnesium ingot weight that every block electrolytic copper need be arranged in pairs or groups.
A kind of up-drawing method copper-magnesium alloy casting alloy element addition means, is characterized in that: magnesium ingot packing step, wraps up the magnesium ingot weighed up with the fine copper Copper Foil that the thickness being cut into suitable size is 0.05mm, then tighten with the low-oxygen copper pole of length 2.5m.
A kind of up-drawing method copper-magnesium alloy casting alloy element addition means, it is characterized in that: addition step, time reinforced, is feed location in the middle of the channel of two smelting furnace, and material bag need stretch into below copper liquid liquid level at least 10cm.
Alloying element addition means of the present invention can reduce the oxide compound of magnesium in stove, reduces the quantity of slag, reduces the frequency of workman's scarfing cinder, labour intensity, decrease the risk being mixed into impurity in copper liquid; Decrease the content of hard crisp phase in strand, improve quality product, improve the utilization ratio of magnesium elements; Meanwhile, reduce the scaling loss amount of magnesium, reduce raw material consumption, reach the effect of saving material and improving slab quality.
Accompanying drawing explanation
Fig. 1 is that alloying element of the present invention adds operational flowchart.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
A kind of up-drawing method copper-magnesium alloy casting alloy element addition means, is characterized in that: comprise calculating addition → magnesium ingot fragmentation → magnesium ingot weighing → magnesium ingot to pack → reinforced, five operation stepss; As shown in Figure 1, according to the weight often criticizing electrolytic copper plate, and the empirical value of magnesium utilization efficiency, calculate the magnesium ingot weight of often adding one piece of electrolytic copper plate and needing collocation to add; Use dedicated hydraulic is cut, and the magnesium ingot of monoblock is cut into fritter, can go out the magnesium of approrpiate wts by accurate weighing in next step; Then, the fritter magnesium ingot that monoblock magnesium ingot and upper step cut out is placed in electronic scales (minimum division value: 1g) and above weighs, weigh up the magnesium ingot weight that every block electrolytic copper need be arranged in pairs or groups; Then with the fine copper Copper Foil that the thickness being cut into suitable size is 0.05mm, the magnesium ingot weighed up is wrapped up, then be about 2.5m's by length
low-oxygen copper pole is tightened; At the channel charge of intermediation of fusing 1 stove channel with fusing 2 stoves, time reinforced, material bag need stretch into below copper liquid liquid level at least 10cm.After reinforced, if remaining
low-oxygen copper pole is of convenient length, and can continue the packing materials'use as lower batch of magnesium ingot.Invention increases the utilization ratio of magnesium elements, decrease the risk being mixed into impurity in copper liquid simultaneously, improve quality product.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention; make some equivalent alternative or obvious modification without departing from the inventive concept of the premise; and performance or purposes identical, then should be considered as belonging to the protection domain that claims that the present invention submits to are determined.
