Problems solved by technology
Although the existing technical solutions are feasible, they have the following deficiencies: many people cooperate, and the work efficiency is low; the cutting and processing personnel stand under the raised heat preservation cover, and the heat preservation cover has a risk of falling, which is a great safety hazard; multiple casting and flow casting are required The opening and closing efficiency is low when the slabs are cut at the same time, and there is a possibility of mutual interference; the lifting frame spanning the top of the strand roller table hinders the maintenance of the roller table

The invention provides an automatic opening and closing heat preservation cover device for continuous casting slab hot delivery roller table and its use method, the device includes: a movable heat preservation cover, including a shell, the shell is a long strip structure with an inverted U-shaped cross section , the shell is slidably set on the fixed heat preservation cover, and the shell is symmetrically installed with at least one pair of supporting rollers; a pair of rails are arranged in parallel on both sides of the heat-feeding roller table, and the supporting rollers are arranged on the rails; the hoisting drive mechanism , including a motor, a drum, a first fixed pulley and a first steel wire rope, one end of the first steel wire rope is fixed on the drum, the other end of the first steel wire rope is fixed on the casing around the first fixed pulley, and the output shaft of the motor is connected to the drum Connection; the reset mechanism includes a second fixed pulley and a reset weight, one end of the second wire rope is fixed on the movable heat preservation cover, and the other end of the second wire rope bypasses the second fixed pulley to suspend the reset weight. The heat preservation cover of the present invention is fully automatic and horizontally opened and closed, and the simultaneous operation of multiple casting streams does not interfere with each other, and requires less manpower.
Description
technical field [0001] The invention relates to the technical field of continuous casting and rolling and continuous casting slab hot delivery, in particular to an automatic opening and closing heat preservation cover device for continuous casting slab hot delivery roller table and its use method. Background technique [0002] Energy conservation, emission reduction, and energy efficiency improvement are the way for steel smelting enterprises to survive today and in the future. In recent years, the research, development and application of continuous casting and rolling technology have achieved remarkable results. The seamless connection between the billet continuous casting machine and the rolling mill can make full use of the waste heat of the billet, and if it is properly controlled, the heating device before rolling can be omitted, and direct hot rolling can be realized, which greatly reduces energy consumption and plays an important role Cost reduction and efficiency enh...
