(3) Adopting horizontal continuous casting, segregation of density (specific gravity) can be generated for alloy metal billets, elements with high density are arranged below, elements with low density are arranged above, and chemical components inside castings are uneven, so that the mechanical property, physical property, abrasion resistance and processing property of the castings are affected;
(4) The horizontal continuous casting is adopted, the metal blank adopts a production process method of positive pulling, stopping, reverse pushing and positive pulling, and faults such as thinning, stretch breaking or leakage and the like are easy to occur for the small-section metal blank;
(5) Adopting the traditional vertical bending (arc) continuous casting, crystallizing by a crystallizer in an arc shape, wherein the inner diameter and the outer diameter of an arc-shaped metal blank are different, when the metal blank is straightened into a straight line state from an arc shape, the section of the metal blank is deformed, the wall thickness is uneven to form an external quality defect, and the metal stress states of the inner diameter and the outer diameter are different;
(6) The traditional vertical bending (arc) continuous casting is adopted, the crystallizer is subjected to arc vibration, the abrasion loss of each direction of the outlet of the crystallizer is uneven due to the influence of gravity, and the service life is low;
(7) The crystallizer is separated from the casting ladle by adopting the traditional vertical-bending (arc-shaped) continuous casting, for small-section metal billets, the volume of the crystallizer is small, the fluctuation of the liquid level height of the crystallizer is greatly influenced by the casting speed, the casting liquid level with reasonable height is difficult to control, the low-speed casting or the high-speed casting cannot be carried out, the manufacturability is poor, and the metal billet range is small;
(8) The traditional vertical bending (arc) continuous casting is adopted, the arc dummy bar is long, the occupied storage space is large, the movement links are many, the auxiliary time is long, and the equipment productivity is low.
How to realize continuous casting production of ultra-long small-section metal blanks, meet the length of the metal blanks, ensure the quality of the metal blanks and realize high-efficiency production is a difficult problem to be solved in the traditional continuous casting production method at present.
