Problems solved by technology
[0006] In addition, for the roller rows arranged in close arrangement in the secondary cooling zone, the foot rollers are very close to the rollers of the lower fan section, and the foot rollers and spraying devices must be careful to avoid the fan section equipment, and the spray angle of the fan section nozzles must not be blocked, otherwise It will affect the cooling effect of the slab

The invention provides a crystallizer foot roller spraying device and a crystallizer foot roller system. The crystallizer foot roller spraying device comprises a foot roller frame, a foot roller spraying water ring arranged on the foot roller frame and provided with a water ring inlet and a plurality of water ring outlets, and a plurality of spray pipes arranged outside the foot roller frame at intervals, the inlet ends of the spray pipes are connected with a plurality of water ring outlets in a one-to-one correspondence mode, a plurality of nozzles facing the inner side of the foot roller frame are arranged on the pipe wall of each spray pipe, and spray water can enter from the water ring inlet and can be sprayed out from the nozzles after sequentially passing through the water ring outlets and the inlet ends of the spray pipes so as to cool casting blanks positioned on the inner side of the foot roller frame. The crystallizer foot roller spraying device and the crystallizer foot roller system have the beneficial effects that the crystallizer foot roller spraying device is used for being connected with a crystallizer so as to provide support and spray cooling effects for the casting blanks coming out of the crystallizer through the crystallizer foot roller system.
Description
technical field [0001] The invention relates to the technical field of continuous casting, in particular to a crystallizer foot roll spray device and a mold foot roll system. Background technique [0002] On the continuous casting machine in the metallurgical industry, the foot roll is the main device below the mold. The role of the foot roller is to guide the dummy rod into the crystallizer, and at the same time protect the copper tube of the crystallizer to prevent the dummy head from damaging the lower opening of the copper tube when the dummy rod is threaded. In addition, there are foot rollers to guide the casting slab during billet drawing, which can support and guide the weak slab shell of the first copper tube, reduce the deformation of the casting slab or breakout, and also reduce the wear of the casting slab on the lower opening of the copper tube. [0003] The spraying device in the foot roll area provides water spray cooling for the casting slab that first exits...
