Description

Technical Field

[0001] This utility model belongs to the field of ignition in smelting equipment, and relates to a safety ignition device for baking ladle in stainless steel smelting plants. Background Technology

[0002] In stainless steel smelting plants, the ignition of the baking oven also uses an ignition rod to ignite the gas burner. The ignition rod is made of wood or steel, with an igniter at the front end. After the igniter is lit, it is raised to the vicinity of the gas burner, the gas is turned on, and the gas burner is ignited.

[0003] This ignition method has the following drawbacks:

[0004] Safety risks: There are potential safety hazards. Operators may suffer burns due to improper operation, such as falling ignition materials.

[0005] Inconvenient to operate: This method is inconvenient to operate, requiring personnel to operate at close range. During operation, the ignition material must first be fixed on a long pole, then the ignition material is lit and lifted up. The labor intensity is high, and the operating space is relatively narrow, resulting in poor working conditions.

[0006] Energy waste: The on-site baking oven has two or more burners. Due to the inconvenience of operation, they cannot be ignited immediately after the gas is turned on, which will result in some energy waste.
