Description
Technical field
The present invention relates to aluminum alloy casting technique, be specifically related to aluminum alloy solid circle ingot casting casting dish and casting method.
Background technology
Previously, when to produce aluminum alloy solid circle ingot casting specification be Φ 120, dishful casting number had been 120, and casting length is 4.8 meters, and like this, during casting, to compare other specifications much larger for melt flow demand.Therefore, usually be less than at the filtration yield of casting filter unit interval middle and later periods and now cast required melt flow, there is crystallizer front end and end on casting dish and there is the problem of the larger temperature difference, when using identical filter specification, cannot normally cast.Thus Long-term Vibration filter can only be adopted to increase the size of melt flow or increase filter, thus meet casting condition.But this way brings very large drawback, add slag inclusion probability greatly or add use cost, occurring product quality defect.Light then change product size, add rejection number; Heavy then whole stove is scrapped.There are the problems referred to above equally in the filled circles ingot casting of Φ 127, Φ 152 two kinds of specifications in casting process.So, there is product percent of pass reduction, production cost increase.
Summary of the invention
The object of the invention is to propose a kind of aluminum alloy solid circle ingot casting casting dish and casting method, to solve the problem of inflow-rate of water turbine deficiency in filled circles ingot casting casting process, avoid therefore and the quality problems that produce simultaneously; Improve the quality of products, reduce production cost.
Aluminum alloy solid circle ingot casting casting dish of the present invention, comprise casting dish, the upper surface of described casting dish is provided with sow (channel), described sow (channel) one end is entrance, the other end of described sow (channel) is by shutoff, the both sides of described sow (channel) are respectively provided with six branch road chutes be communicated with described sow (channel), and the both sides of each described branch road chute are respectively equipped with three crystallizers be communicated with this branch road chute, and the degree of depth of described crystallizer is not less than 9.4 meters.
The invention allows for aluminum alloy solid circle ingot casting casting method, comprising:
A) prepare burden according to the composition of aluminium alloy, the raw material after batching is carried out melting;
B) melt after melting is imported holding furnace, and adopt mist to carry out refining, described mist is chlorine and argon
The mist of gas;
C) by step B) melt that obtains carries out online degasification and on-line filtration successively;
D) by step C) melt that obtains imports in above-mentioned casting dish and casts, and casting speed is 150 ~ 160mm/min, is 730 DEG C ~ 750 DEG C in casting temperature stove, obtains the casting rod that length is 9.4 meters after having cast;
E) by step D) casting rod that obtains 9.4 meters is divided into two length to be the casting rod of 4.5 meters.
Further, step B) in mist in the volume ratio of chlorine and argon gas be 1:9.
Casting dish of the present invention, owing to decreasing the quantity of crystallizer, improve the flow direction of melt, make to require to reduce to melt flow, reduce the temperature difference phenomenon of often arranging crystallizer, avoid the situation of melt flow deficiency, improve yield rate, deepen crystallizer simultaneously, casting length is changed into 9.4 meters, a casting rod can process the casting rod that two length are 4.5 meters, unit heat crop, cabrage amount decreases about 50%, decrease waste, reduce cost, the present invention has carried out melting successively, refining, online degasification, the operation of on-line filtration and casting, in the process of casting, by casting temperature and casting speed are allocated, obtain best proportioning, thus the yield rate of aluminium alloy cast rod is greatly improved, comprehensively yield rate can be improve 3.5-4.0% than before.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing casting dish;
Fig. 2 is the structural representation of casting dish of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Aluminum alloy solid circle ingot casting casting dish as shown in Figure 2, comprise casting dish 1, the upper surface of described casting dish 1 is provided with sow (channel) 2, described sow (channel) 2 one end is entrance, the other end of described sow (channel) 2 is by shutoff, the both sides of described sow (channel) 2 are respectively provided with six branch road chutes 3 be communicated with described sow (channel) 2, and the both sides of each described branch road chute 3 are respectively equipped with three crystallizers 4 be communicated with this branch road chute 3, and the degree of depth of described crystallizer 4 is not less than 9.4 meters.
Aluminum alloy solid circle ingot casting casting method, comprising:
A) prepare burden according to the composition of aluminium alloy, the raw material after batching is carried out melting;
B) melt after melting is imported holding furnace, and adopt mist to carry out refining, described mist is chlorine and argon
The mist of gas;
C) by step B) melt that obtains carries out online degasification and on-line filtration successively;
D) by step C) melt that obtains imports in above-mentioned casting dish 1 and casts, and casting speed is 150 ~ 160mm/min, is 730 DEG C ~ 750 DEG C in casting temperature stove, obtains the casting rod that length is 9.4 meters after having cast;
E) by step D) casting rod that obtains 9.4 meters is divided into two length to be the casting rod of 4.5 meters.
Further, step B) in mist in the volume ratio of chlorine and argon gas be 1:9.Chlorine produces chemical reaction and generates NaCl, CaCl2 and arrive and remove the object of Ca, Na in the process floated with Na, Ca etc. of melt, utilize argon gas to the suction-operated of each type impurity, each type impurity is removed, utilize the method for physics, not only do not bring additional impurities into, and simplify refining procedure.Volume ratio is 1:9 is optimum proportioning, adopts above-mentioned mist can improve the quality of casting rod.
Concrete, Fig. 1 is existing casting dish 5, and its casting number is 120, is provided with totally 120 crystallizers.Casting length be 4.8 meters can the casting rod of sawing 120 4.5 meters.Fig. 2 is casting dish of the present invention, decrease the quantity of crystallizer, improve the flow direction of melt, in casting process, reduce the phenomenon that crystallizer front end and end exist the larger temperature difference, casting number is 72, and extends casting length, can cast 72 9.4 meters after improvement can the casting rod of sawing 144 4.5 meters, unit heat crop, cabrage amount decrease about 50%, and can obtain the casting rod that more length is 4.5m, improve casting efficiency.Method of the present invention is also applicable to Φ 127, the filled circles ingot casting of Φ 152 two kinds of specifications is cast, and needs to carry out accommodation to casting speed when casting the filled circles ingot casting of these two kinds of specifications.Casting rod in literary composition is round ingot casting, and the arrow in Fig. 1 and Fig. 2 is melt flows direction.
