Description

Technical Field

[0001] The utility model relates to the technical field of steel ingot casting, and particularly discloses an extended tube carrying platform for pouring steel ingots. Background Art

[0002] Casting steel ingots transforms liquid steel into solid ingots, providing raw material for subsequent steel production. Pouring is a crucial step between steelmaking and rolling. It involves pouring molten steel into molds, allowing it to solidify and form, ultimately creating the desired ingot shape. This process not only affects the quality of the ingot but also significantly impacts subsequent steel production. Because solidification of molten steel is an irreversible process, the precision of the pouring process plays a crucial role in ingot casting technology.

[0003] When pouring steel ingots, as the pouring speed increases, the precipitates in the liquid phase during the thermal decomposition of the mold will gradually increase, and the gap between the molten metal and the foam mold will decrease, resulting in an intensified carbon increase process. In order to reduce carbon increase, the principle of designing the pouring speed is to make it as consistent as possible with the removal speed of the gas pyrolysis products of the mold, so that the mold can be vaporized as quickly as possible. With the cooperation of the extension tube, the operator can use the extension tube to remove the gasification products outside the mold, thereby reducing carbon increase and ensuring the casting quality of the steel ingot.

[0004] At present, after using the extension tube, the operator usually places the extension tube in clean water to quickly cool down the extension tube, so that it is convenient to continue to use it in the subsequent steel ingot casting process; since some molten steel will remain on the surface of the extension tube during the contact with the molten steel, the molten steel will form cast iron particles on the surface of the extension tube after cooling. In order to ensure the surface smoothness of the extension tube, the operator needs to use a grinder to grind the surface of the extension tube to eliminate the cast iron particles on the surface of the extension tube for subsequent use; it can be seen that the above-mentioned existing technology requires the casting personnel to maintain the extension tube in time, which wastes the casting personnel's working time, reduces the overall working efficiency of casting steel ingots, and generates maintenance costs, and has high operating limitations.
