desc: The stainless steel continuous annealing pickling line is used for annealing and pickling various types of stainless steel to achieve the required mechanical properties and surface quality. It is mainly divided into hot-rolled stainless steel annealing pickling lines, cold-rolled stainless steel annealing pickling lines and cold-rolled stainless steel bright annealing lines. Our company has successively constructed ten such lines both domestically and overseas.
- Welding Machine：Adopts a complete welding process of shearing → butt jointing → welding → punching → edge trimming. Both the inlet and outlet are equipped with automatic steel strip centering devices. The clamping devices feature uniform force application and adjustable pressure, with longitudinal and transverse movement functions, as well as the function of steel strip lap angle compensation.
- High-pressure Hot Water Scrubbing and Rinsing：The water temperature is approximately 80℃, equipped with a hot water circulation system for rinsing. After degreasing treatment, it can ensure the surface cleanliness of the steel strip and meet the requirements of subsequent processes.
- Annealing Furnace Preheating Zone：Makes full use of the exhaust gas from the heating furnace to preheat the steel strip, effectively improving the thermal efficiency of the furnace and achieving energy conservation and consumption reduction.
- Pickling Process：Adopts a combined process of neutral salt electrolytic pickling + mixed acid pickling to stably guarantee pickling quality and ensure that the product surface meets the standards.
