Embodiment 1

[0026] Such as figure 1 As shown, the slag adding device of the present invention includes: a loading vehicle 5 and a hopper 11 . The carrying vehicle 5 is rotatably connected to the delivery hopper 11 through the rotary screw 6, and the delivery hopper 11 can move around the rotary screw 6. The hopper 11 includes a head end and a tail end, and the head end is connected with the carrying vehicle 5 . The tail end of the feeding hopper 11 is connected to the vibrating crystallization platform 18 through a connecting component, and receives the vibration of the vibrating crystallization platform 18, driving the tail end of the feeding hopper 11 to swing up and down. The hopper 11 is configured as a bar-shaped trough with a bottom wall and two opposite side walls.

[0027] The bottom of the carrying vehicle 5 is provided with universal wheels 22 for moving the carrying vehicle 5 . The universal wheel 22 is also provided with a brake 23, stepping on the brake 23 can fix the posi...

Abstract

The invention relates to the technical field of iron and steel smelting and discloses a casting powder adding device. The device comprises a storage tank, a bearing cart and a conveying bin, wherein the output of the storage tank is arranged over the head end of the conveying bin, a filtering net is arranged in the middle of the storage tank, casting powder falls onto the conveying bin through theoutput of the storage tank, the head end of the conveying bin is rotationally connected with the bearing cart through a rotary screw, the tail end of the conveying bin is inclined downwards relativeto the head end of the conveying bin, the inclination degree can be adjusted, and a vibrating crystalization platform drives the tail end of the conveying bin to swing up and down so that the castingpowder can uniformly fall into a crystallizer in the center of the vibrating crystalization platform. According to the casting powder adding device, the inclination degree and the vibration amplitudeof the conveying bin can be adjusted by adjusting the height of a nut instead of by using extra media or consuming other energy, thus, the casting powder adding rate can be adjusted, requirements of different steel grades at different pulling rates can be met, and the device is simple in structure, convenient to operate and wide in application range and occupies little space.

Description

technical field [0001] The invention relates to the technical field of iron and steel smelting technology, in particular to a continuous casting mold slag adding device. Background technique [0002] As we all know, the crystallizer is the heart of continuous casting. The molten steel is cooled through the mold to form a primary billet shell, which is separated by the reciprocating movement of the mold up and down. During this process, it is necessary to continuously add to the surface of the molten steel in the mold. Mold slag, the added mold slag can not only keep warm, isolate the air, prevent the secondary oxidation of molten steel and absorb inclusions, but also control the lubrication and heat transfer between the billet shell and the crystallizer, so as to realize the continuous casting process went smoothly. Therefore, it is of great significance to develop mold flux application technology for continuous casting. [0003] Due to the complexity of the continuous cas...
