Description
Technical field
It the utility model is related to up-drawing method production copper process equipment, and in particular to a kind of crystallizer for up-drawing method production copper.
Background technology
Up-drawing method is widely used in production oxygen-free copper bar, cathode copper is fused into liquid through power frequency induction furnace, warm stove will
Copper liquid temperature is controlled in prescribed limit, and copper liquid enters graphite jig and passes through upper lead conticaster quick crystallisation by cooling in a crystallizer
Continuously produce copper bar.During wherein copper liquid is changed into copper bar, the speed and quality of crystallization, it is related to anaerobic
The yield of copper bar and follow-up machinable plasticity, the cooling after crystallization are also related to the quality on the surface of product, when cooling is imitated
In the state of fruit is undesirable, the yield of copper bar is also influenced whether.Comparatively on the premise of product following process plasticity is ensured.
The speed of crystallization is faster, and the yield of continuous up-casting is higher.Cooling effect after crystallization is better, and quality, the yield of product are higher.
The primary structure of the existing crystallizer for up-drawing method production copper is as shown in figure 1, be sheathed on including core pipe 1 and successively

This stage copper is liquid；Second stage, copper liquid enter the connecting portion of graphite jig and copper sheathing, and this stage is due to the work of cooling water
With, copper liquid release amount of heat, and semisolid is changed into until solid-state by liquid；Phase III, copper liquid are coagulated in graphite jig
Draw along core pipe after knot, in the presence of cooling water, persistently the copper bar formed in core pipe is cooled down.Second stage, copper by
Liquid is changed into semi-solid until the process of solid, is the committed step that up-drawing method produces oxygen-free copper bar；In its crystallization process, if
Cool down excessive, easily cause cold shut；If cooling is too small, red heart is easily caused（Copper bar cooling is the process of ecto-entad Step crystallization, interior
Portion's incomplete cooling effect of crystallization is inadequate, can cause red heart, oxidation）Product is caused defect occur.Phase III, copper bar is by graphite
Condense in mould and finish, now copper bar surface temperature is very high, it is necessary to persistently cooled down, make copper bar go out crystallizer after temperature drop
To less than 50 degree, to prevent copper bar from oxidation reaction occurs with the oxygen gas and water in air at high operating temperatures.
Heat exchange is carried out to core pipe and copper sheathing simultaneously by single intake tunnel, causes crystallizer can not control phase simultaneously
The cooling requirement of second stage and phase III are answered, influences copper bar cooling effect, limit copper rod up-leading speed, consequently, it is possible to produce
It can be restricted, production cost also necessarily rises.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of crystallizer for up-drawing method production copper, it can solve existing
Crystallizer can not control the cooling requirement of above-mentioned second stage and phase III simultaneously, influence copper bar cooling effect, limit copper bar
