Manufacturing Process
Steel Making BQ steel and BQ Plates are typically made through basic oxygen or electric arc furnace processes and Casting and Rolling The steel is cast into slabs and then hot rolled to achieve the desired thickness and Heat Treatment: Post-rolling, the plates undergo heat treatment processes such as normalizing, quenching, and tempering to enhance their mechanical Properties and Quality Control Rigorous testing, including ultrasonic testing, impact testing, and tensile testing, is conducted to ensure the plates meet the required standards.
Key Features and Properties of Boiler Quality Steel Plate
- Durability: The plates are highly durable and provide a long service life even under harsh operating conditions.
- Resistance to High Temperature: These plates can withstand high temperatures, which is critical for boiler and pressure vessel applications.
- High Strength: BQ steel plates are engineered to offer high tensile strength, allowing them to endure the pressure inside boilers and pressure vessels without deforming.
- Corrosion Resistance: BQ steel plates often have enhanced corrosion resistance, making them suitable for use in environments where they are exposed to chemicals and other corrosive substances.
Applications
- Pressure Vessels: Used in the storage and transportation of gases and liquids under high pressure.
- Heat Exchangers: These plates are also used in the production of heat exchangers, which are critical in energy transfer processes.
- Oil & Gas Industry: Employed in the construction of offshore and onshore oil drilling platforms, storage tanks, and pipelines.
- Boilers: BQ steel plates are essential in the manufacture of boilers, which are used in power plants, industrial facilities, and residential heating systems.
