The ladle is fully covered with a cover device and a molten steel carrying device

Abstract

The invention provides a steel ladle full-course covering and uncovering device and a molten steel carrying device. The steel ladle full-course covering and uncovering device comprises a fixed stand column, a lifting hydraulic cylinder, a lifting stand column, a rotation driving motor, a slewing bearing, a rotary frame, a transverse moving hydraulic cylinder and a transverse moving trolley. The fixed stand column is fixed on a platform; the lifting stand column is connected onto the fixed stand column in a sleeving manner; the lifting hydraulic cylinder drives the lifting stand column to go up and down along the fixed stand column; the rotary frame comprises a vertical rod and a horizontal rod connected with the vertical rod; the bottom of the vertical rod and the top of the lifting stand column are connected through the slewing bearing; the rotation driving motor is fixed on the lifting stand column and drives the slewing bearing to rotate so as to drive the rotary frame to rotate; the transverse moving trolley is positioned on the horizontal rod; and the transverse moving hydraulic cylinder drives the transverse moving trolley to move along the horizontal rod. The steel ladle full-course covering and uncovering device has low requirements for clearance above a steel ladle, is free of impact during covering and uncovering, and is low in equipment failure rate, small in maintenance quantity and smooth in production.

Description

technical field

[0001] The invention relates to the technical field of converter steelmaking, in particular to a whole-process uncovering device for a ladle and a carrying device for molten steel. Background technique

[0002] In the early converter steelmaking production process, whether it was during the transportation of molten steel in ladles, or during the transportation and thermal repair of empty ladles, molten steel and ladle linings would lose a lot of heat energy. There are two main ways of heat loss : The first is the heat radiation through the ladle lining and the air, and the second is the heat radiation from the contact between the molten steel and the air. In order to ensure the temperature of the inner lining of the ladle when the ladle receives molten steel, a ladle baking device must be installed to bake the inner lining of the ladle. At the same time, with the improvement of steel properties, the requirements for temperature fluctuation of molten steel ar...
