Problems solved by technology

There are certain disadvantages in the existing method: 1) waste of watering can
The small nozzle of the watering can will easily cause the nozzle to be clogged during use, affecting the effect of the spray point, the operation rate is low and the cost is wasted
2) Waste of human resources
The personnel in the production process is extremely tense now, but this work must be handled by a special person, and cannot be taken care of by others, otherwise it is easy to miss or forget to spray, resulting in passive production

Embodiment Construction

[0018] In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation mode combined with the accompanying drawings.

[0019] It can be seen from the accompanying drawings that a slab automatic spraying device of this scheme includes a compressed gas supply pipe 6, a limit baffle 2 fixed on the cutting machine 1, and the limit baffle 2 and the cutting machine 1 are welded or bolted. A limit switch 3 cooperating with the limit baffle plate 2 is arranged on one side of the billet, the limit switch 3 is connected in series with the solenoid valve 4 and then connected in series with a power supply 12, and the power supply 12 is 24V DC power supply. The compressed gas supply pipe 6 communicates with the nozzle 5 for spraying, the solenoid valve 4 is arranged on the compressed gas supply pipe 6, and a high temperature resistant paint pipe 7 communicates with the nozzle 5. The nozzle 5 is fixed on the noz...

Abstract

The invention provides a technical scheme of an automatic point spraying device for a casting blank. The automatic point spraying device comprises a compressed-air supply tube and a limiting stop plate fixed on a cutting machine. A limit switch matched with the limiting stop plate is arranged on one side of the casting blank, and is in series connection with a power supply after being in series connection with an electromagnetic valve. The compressed-air supply tube is communicated with a spray nozzle used for spraying. The electromagnetic valve is arranged on the compressed-air supply tube. A high-temperature-resistant coating tube is communicated with the spray nozzle. The automatic point spraying device is high in safety, on-site operation of workers is not needed, and thermal radiation to the workers is avoided.

Description

technical field [0001] The invention relates to the field of metallurgical equipment, in particular to a billet automatic spraying device. Background technique [0002] In the prior art, it is known that continuous casting slab spraying is a common production process in steelmaking and continuous casting production. In the production process, when the billet is cut, it needs to be sprayed, and when both casting machines are red-feeding, it is also necessary to distinguish which caster the red-feeding billet comes from. The current casting slab spraying device mainly uses a watering can to spray high-temperature paint on the surface of the slab under the action of compressed air, and all processes are manually operated. There are certain disadvantages in the existing method: 1) The watering can is wasteful. The small nozzle of the watering can will easily cause nozzle clogging during use, which will affect the effect of the spray point, the operation rate is low and the cos...
