Heat insulation pouring ladle with ladle lining push-out device

Abstract

The invention discloses a heat insulation pouring ladle with a ladle lining push-out device. The heat insulation pouring ladle comprises a ladle shell and a ladle beam arranged on the ladle shell. Thetwo sides of the ladle shell are each provided with a ladle shell shaft, vertical rods are mounted on the ladle shell shafts, and the ladle beam is mounted on the vertical rods. The ladle shell shafts are connected with a speed reducer, and a ladle wheel is mounted on the speed reducer. A ladle nozzle is arranged on the upper edge and the edge of the ladle shell, and a primary slag blocking brickis arranged between the interior of a cavity of the ladle shell and the ladle nozzle. A communicating ladle nozzle runner is arranged along the edge of the inner side of the ladle shell, and a secondary slag blocking brick is arranged on the upper portion of the ladle nozzle runner. A heat insulation layer is further arranged between the side wall of the ladle shell and the ladle nozzle and refractory matter, and heat insulation brick layers are arranged in the position, on the ladle shell, of the refractory matter and in the position, at the bottom of the ladle shell, of the refractory matter to achieve heat insulation. The ladle wheel is rotated, so that molten steel flows out from the bottom of the ladle shell along the ladle nozzle runner. By means of the heat insulation pouring ladle, the heat insulation performance of the pouring ladle is improved; and after the pouring ladle which is just offline is cooled, a ladle lining can be dismounted, and the speed of dismounting the ladle lining is increased.

Description

technical field [0001] The invention belongs to the field of mechanical casting, and in particular relates to a thermal insulation pouring ladle with a lining push-out device. Background technique [0002] At present, with the rapid development of science and technology, the production efficiency of the production line is also constantly improving, and the production process requirements are also more stringent, which narrows the pouring temperature range; because the pouring line is poured, although the pouring ladle has a form of heat preservation However, there is still a phenomenon that the average temperature of the molten steel drops by about 10°C per minute in the pouring ladle. The normal temperature range of pouring is exceeded, so it cannot meet the process requirements. [0003] When the pouring ladle is off-line, the lining of the pouring ladle needs to be cooled first, and then manually removed; since the cooling time is more than 4 hours, and it takes about 2 ...
