Production technology and characteristics of French forgings

In the industrial field, flange forgings, as an important mechanical component, are widely used in the connection and fixing of pipes, valves, pressure vessels and other equipment. The production process is complex and the quality requirements are strict. The production process and characteristics of flange forgings will be introduced in detail below.
First, the production process
Raw material preparation: First of all, select the appropriate raw materials, such as carbon steel, stainless steel, alloy steel, etc., to ensure that its chemical composition, mechanical properties and metallographic structure meet the standard requirements.
Blank preparation: According to the requirements of the design drawings, the raw materials are cut, planing, pre-bending and other processing to prepare the blank suitable for forging.

Heating: the billet is put into the heating furnace and heated to make it reach the appropriate forging temperature. In the heating process, the temperature and time should be controlled to avoid defects such as over-burning and decarbonization.
Forging: Plastic deformation is carried out on the forging equipment, and the basic shape and size of the flange forging is formed by hammering, extrusion, bending and other technological means.
Trimming and shaping: trimming and shaping the flange after forging to remove excess metal materials to ensure the flatness and accuracy of the flange.
Cooling and tempering: The flange forgings are cooled naturally or controlled, and tempered according to the material and process requirements to improve their mechanical properties and service life.
Inspection and storage: Quality inspection of finished flanges, including size, appearance, non-destructive testing, etc., packaging and storage after passing.
Ii. Characteristics
High strength: flange forgings after high temperature forging and tempering treatment, with high strength and toughness, can withstand greater pressure and vibration.
High precision: Through precise forging and processing technology, the dimensional accuracy and form and position tolerance of flange forgings are effectively controlled, and can meet the high standard of connection requirements.
Long life: High quality raw materials and fine processing technology ensure the long service life of flange forgings, reducing the frequency of maintenance and replacement.
Good sealing performance: flange forgings have good sealing performance when connected, which can effectively prevent media leakage and ensure the safe operation of the equipment.
Wide applicability: flange forgings can be selected according to different working conditions and media of different materials and processes, widely used in petroleum, chemical, electric power, pharmaceutical and other fields.
High degree of customization: According to customer needs, flange forgings can be customized with different specifications, models and connection methods to meet individual needs.
Environmental protection and energy saving: In the production process, the use of advanced production technology and equipment to reduce energy consumption and reduce waste emissions, in line with environmental protection requirements.
Safe and reliable: flange forgings in the production process through strict quality control and safety testing to ensure the safe and reliable performance of the product.
Easy maintenance: flange forging structure is simple, compact, easy to install and maintain, reduce the cost of use. Economy: Although the one-time investment cost of flange forgings is higher, its long life and low maintenance costs make it more economical.
In short, flange forging as an important industrial component, its production process is complex and fine. Understanding its production process and characteristics is helpful to better select and apply flange forgings, and provide guarantee for the stable operation of industrial equipment.
