The examination casting of same casting time different size at first must guarantee production safety, and secondly the examination casting must be satisfied with alloy and the close condition of crystallizer specification, technological parameter mainly follow following some:
1, casting speed: the inconsistent alloy of casting speed serves as main slowly and can suitably adjust with casting speed, because the too fast meeting of casting speed makes the liquid cave deepen (H liquid cave=KV casting), the intermediate zone size broadens, the crystalline structure alligatoring, feeding worsening condition during crystallization increases the center porosity tendency.
The casting speed of each specification stabilization sub stage is more or less the same, between 55-60mm/min (casting speed of removing the 630*1860 specification is 72mm/min).For example: two kinds of crystallizers of 560*1310 and 620*1150 specification, their casting speed is respectively 55mm/min, 60mm/min, the other 0.7336m of crystallizer cavity surface integration
2, 0.7130m
2, both are more or less the same, and can cast the slab ingot of these two kinds of specifications in same casting is inferior, and casting speed will adopt 55mm/min.
2, discharge: the inconsistent alloy of discharge, with big the serving as main and can suitably adjust of discharge.Solute element has little time diffusion in the increase melt of intensity of cooling, and crystal grain attenuates and diminishes, and the ingot casting density improves.And, when casting speed is slow, can make the tendency of cold shut become big, but the tendency of segregation emersion thing and drawing crack is reduced along with the raising of intensity of cooling.
Still with 560*1310,620*1150 specification crystallizer discharge 560*1310 specification 818ml/ root, 620*1150 specification 641ml/ root will be taked the crystallizer discharge 818ml/ root of 560*1310 specification.
3, liquid level: liquid level is inconsistent, with high the serving as main and can suitably adjust of liquid level.Liquid level is low, intensity of cooling is big, is easy to leak aluminium, the surface quality variation.
4, casting temperature: casting temperature is inconsistent, with high the serving as main and can suitably adjust of casting temperature.Improve temperature within the specific limits, ingot casting liquid cave deepens, crystallization temp gradient at front edge steepening, and cooling velocity is big during crystallization, can make the intracrystalline refinement, and liquid fluidity can improve simultaneously, and oxide-film can reduce.
Crystallizer specification difference, difference in various degree also appears in Dui Ying casting alloy technological parameter with it.In the continuous casting, the factor that influences ingot quality has: liquid level and fill rate, casting speed, casting temperature in the flow of water and cooling velocity, the crystallizer.The common ground that technological parameter at different size compared, analyzed characteristics separately and sums up close specification, with casting time same specification and the comparison of casting time different size ingot casting together:
Surface quality:
Contrast two kinds of production methods, the surface quality no significant difference of product ingot casting all meets the correlation technique standard-required.
Internal soundness: to aluminium and aluminium alloy flat bloom, all carried out sampling the ingot casting macrostructure is analyzed, all met the requirement that grain size number is not more than 2 grades with casting time different size.
After repeated discussions with simulation, starting velocity, discharge and fill rate that the key point of two kinds of specifications of collocation is promptly cast.Gather as follows by the inferior situation of finishing two specifications of casting of comparative analysis:
| Specification | 520x1480 560x1350 560x1310 560x1230 620x1150 | 630x1570 620x1520 580*1570 520*1700 | 560x1950 640x2130 | 620x1780 560x1850 560x1950 | 620x1780 620x1650 620x1600 560*1850 |
A kind of casting process of aluminum alloy slab ingot of present embodiment has the following advantages:
1, improve before every casting time can only cast a kind of aluminium alloy flat bloom of specification, improve a back casting and time can cast two kinds even plurality of specifications aluminium alloy flat bloom.
2, brought into play founding production capacity to greatest extent, increased substantially production efficiency, reduced production costs simultaneously.
3, reduce metal and overstock, accelerated velocity of funds.
Reduce labor strength when 4, improving output.
