The hoisting of the hot billet adopts the magnetic disk hoisting adsorption transportation of a crown block, the adsorption capacity of the magnetic disk is reduced when the temperature is higher, and the danger coefficient of the casting billet with high temperature is high in the hoisting process, so that the safety of personnel and equipment is threatened; the temperature of the hoisting magnetic disk is high for a long time in summer, so that the insulating grease inside is melted, and the magnetic disk is dripped out and burnt from the inside to cause the damage of the magnetic disk, and the cost is greatly wasted.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the aforesaid not enough and provide a device that reduces hot base temperature of continuous casting fast. The temperature of the hot blank is greatly reduced after improvement, the temperature around the equipment is reduced by the evaporation of water mist, and the economic and safety effects are obviously improved.

The technical solution of the utility model is that: the device for rapidly reducing the temperature of the continuous casting hot billet is characterized by comprising a water pipe, wherein an air pipe is arranged in the water pipe, a plurality of vertical branch water pipes are arranged at intervals along the length direction of the water pipe, a branch air pipe communicated with the air pipe is arranged in each branch water pipe, and a nozzle is arranged at the end of each branch water pipe and the branch air pipe; the water pipe is connected with a branch pipeline led out from a production field water pipeline, and the starting end of the branch pipeline is sequentially provided with an adjusting valve, a pressure valve and a pressure gauge; the air pipe is connected with a compressed air pipeline, and the starting end of the compressed air pipeline is sequentially provided with a regulating valve, a pressure valve and a pressure gauge.

The nozzle has a 120-degree spray angle.

The utility model has the advantages that: 1. the device greatly prolongs the service life of the cooling bed bearing. In the past, in summer, 3-4 magnetic disks are damaged due to the fact that the temperature is high and the magnetic disk suspension insulating grease is melted and burned, and only one set of magnetic disks are damaged in the whole summer through the device, so that the cost is greatly reduced. 2. The temperature is reduced, the hoisting safety of the hot billet is improved, the hoisting capacity is improved, and powerful conditions are provided for improving the drawing speed and increasing the yield.

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
