Description

Technical Field

[0001] This utility model relates to an automatic ignition device for flame spraying, belonging to the field of flame spraying technology. Background Technology

[0002] Currently, liquefied petroleum gas (LPG) is used to spray lubricate the casting rolls in casting and rolling production, effectively separating the casting plate from the rolls and ensuring the surface quality of the casting plate. However, due to changes in LPG pressure and the influence of on-site airflow, the spray flame often goes out. Since LPG is denser than air, if not detected promptly, it can easily affect the quality of casting products and production safety. Because current LPG spraying lacks flame detection and automatic ignition devices, the resulting flame extinguishing affects product quality and personnel safety, posing a certain adverse impact on practical use. Therefore, improvements are needed to address the problem of untimely detection and inability to automatically ignite the flame during casting and rolling, which affects product quality and personnel safety.
