1. Core functions and uses
Efficient grease removal
Flame degreasing machines are mainly used for the pretreatment of grease and oil stains on the surface of steel cylinders (especially the outer wall). The high-temperature flame directly burns the surface of the steel cylinder to quickly decompose the grease residue and ensure the adhesion and quality of subsequent processes such as painting, shot peening or welding1314.

Technical advantages: Compared with chemical degreasing agents (which require immersion and waste liquid treatment), flame degreasing does not require chemical agents, is more environmentally friendly, and is suitable for the rapid treatment of large-sized steel cylinders1315.

Process adaptability
Usually used as the front-end equipment of the steel cylinder pre-press processing line, it is used in conjunction with subsequent shot peening machines (such as the QGN series). For example, after flame degreasing, the steel cylinder can enter the shot peening machine to further remove the oxide scale or rust, forming a complete surface treatment process61415.

2. Equipment structure and technical parameters (speculation)
Flame system design

A gas (such as natural gas or propane) combustion device may be used to control the flame temperature and coverage through an adjustable nozzle to adapt to different cylinder diameters (such as φ219-426mm)614.

Equipped with automatic ignition and safety monitoring system to prevent gas leakage or flashback risks.

Conveying and positioning device

Referring to the design of the shot blasting machine, it may include a roller conveyor belt or a flip rack to ensure that the cylinder passes through the flame area at a uniform speed and is evenly heated15.

Applicable cylinder length range: 650-2400mm (consistent with the compatibility of the shot blasting machine)715.

Environmental protection and safety configuration

Integrated dust removal system, the exhaust gas generated by combustion needs to be treated by a filter device to ensure that the emission meets the standard of ≤100mg/m³615.

The surface of the equipment may be covered with an insulation layer, and an emergency stop button and temperature sensor are set to prevent accidents caused by overheating.

3. Application scenarios and advantages
Industrial field
Applicable to surface pretreatment of pressure vessels such as liquefied gas cylinders and oxygen cylinders to improve the durability of painting or coating processes1415.
In the process of refurbishing or remanufacturing steel cylinders, it replaces the traditional alkaline water immersion method and reduces the cost of wastewater treatment313.
Efficiency and cost advantages
The processing speed is estimated to be 2-3 meters/minute (refer to similar shot blasting equipment), and hundreds of steel cylinders can be degreased in a single shift (8 hours)715.
Low energy consumption, only gas and electricity are required for driving, and no chemical agents are required1314.
IV. Precautions and maintenance
Operation specifications
It must be operated by professionals, and the status of gas pipelines and burners must be checked regularly to avoid safety hazards15.
The flammable substances (such as paint) remaining on the surface of the steel cylinder must be cleaned in advance to prevent incomplete combustion from producing harmful gases.
Equipment maintenance
Regularly clean the carbon deposits in the combustion chamber and replace aging nozzles and fireproof materials15.
It is recommended to check the dust removal system filter after each shift to ensure that the emission meets the standard 615.

Summary
The flame degreasing machine quickly decomposes the grease on the surface of the cylinder through high-temperature flames. It is an efficient and environmentally friendly pre-press processing equipment. Its design needs to combine gas combustion technology, automatic conveying system and safety protection measures to form a coordinated process with the shot blasting machine
