Embodiment

[0020] A method for replacing a sliding plate and a drain of an off-line baking continuous casting ladle, such as figure 1 As shown, the steps are as follows:

[0021] 1) Oxygen blowing and cleaning of the nozzle hole: start the electric switch of the oil cylinder to make the slide plate fully open (align the hole of the lower slide plate with the hole of the upper slide plate) 1. The residual steel attached to the hole of the upper slide plate (5), the hole of the upper nozzle (2) and the hole of the block (1) of the upper nozzle are blown clean;

[0022] 2) After cleaning the nozzle hole by blowing oxygen, do not remove the old upper slide (5), lower slide (6) and water outlet (8), lift the ladle from the packing preparation position to the off-line baking position by driving, and carry out baked, ready to use;

[0023] 3) Before the steel ladle for offline baking is planned to be put into use, the steel ladle is hoisted from the offline baking position to the packing prep...

Abstract

The invention relates to a sliding plate for off-line baking a continuous casting ladle and a molten steel outlet replacing method, belonging to the technical field of steel-making sliding molten steel outlet processes. The method is characterized by comprising the following steps: firstly, placing a ladle sliding molten steel hole at a baking position for baking and standby after blowing oxygen and firing and washing without dismantling a used sliding plate and a molten steel outlet; dismantling the used sliding plate and the molten steel hole before the ladle is planned to be input and used, and then arranging a new sliding plate and a new molten steel outlet so as to lead the ladle to be normally produced on-line. Because of adopting the method, the problem of the heavy accident of ladle penetrating caused by not opening the sliding plate due to long off-line baking time during interrupted production of a continuous casting machine is solved. The method can prolong the use continuous time of the sliding plate and the molten steel outlet by 3-4 furnaces, realizes secondary utilization of the sliding plate and the molten steel outlet after the use, and can lower the cost of steel of the sliding plate and the molten steel outlet per ton by more than RMB 0.5yuan.

Description

technical field [0001] The invention relates to an off-line baking continuous casting ladle sliding plate and a method for replacing a water outlet, belonging to the technical field of steelmaking sliding nozzle technology. Background technique [0002] With the integration of production, marketing and research in iron and steel enterprises and the establishment of "order-based" production organization models, the "intermittent" production of continuous casting machines has become a normal phenomenon due to the constraints of varieties, batches, maintenance and other factors. Especially under the current realistic conditions of excess steel production capacity and weak steel market, the "intermittent" production of continuous casting machines has become the main organizational mode of continuous casting production. The "intermittent" production of the continuous casting machine makes the continuous casting ladle forced to bake off-line. The traditional off-line baking ladle...
