Description

Technical Field

[0001] The utility model relates to the technical field of blast furnace slag flushing treatment, in particular to a slag grab bucket for blast furnace slag flushing. Background Art

[0002] The blast furnace is made of steel plates as the furnace shell, and the shell is lined with refractory bricks. The blast furnace body is divided into five parts from top to bottom: furnace throat, furnace body, furnace waist, furnace belly, and furnace hearth.

[0003] The blast furnace slag grabbing operation is an important process in the traditional bottom filtration slag treatment process. Currently, the slag grabbing in the filter tank is mainly carried out manually by using a slag grabbing crane.

[0004] However, the temperature of blast furnace slag is generally high after discharge. After long-term use, the temperature of the grab will increase. Excessive temperature will affect the service life of the grab. In addition, slag dust will be generated when grabbing the slag. Therefore, it is necessary to improve the slag grabbing.
