Cold Rolled Special Steel Strip
High precision hardened and tempered cold rolled steel strip has high requirements for production technology. In steelmaking, hot rolling, cold rolling, heat treatment and finishing of the various processes are more difficult to produce, its full process of consistent manufacturing technology, especially hot rolling control and heat treatment are the core.
Volda is using the mode of hot-rolled blanks from large steel companies such as BaoSteel, Shougang Steel, utilizing special mills to process cold rolling and annealing to meet the requirements of the refined industry steel products. We have processing and forming simulation and analysis technology for cold rolled steel strip and can carry out heat treatment, welding, stamping, roller pressure, rotary pressure, thermoforming and hydroforming and other process simulation and simulation analysis. We also can provide users with high strength steel forming technical support and mold improvement support as well as 50kg-500kg sample testing with advanced technologies from steelmaking – hot rolling – pickling – cold rolling – annealing and other processes.
With multiple SGI workstations, equipped with a full range of CAD and CAE analysis software, we are able to analyze stamping forming, rebound and collision for cold rolled high carbon steel. For examples, material chemical composition, tissue properties such as yield strength, tensile strength, n-value, r-value, elongation, etc., as well as material data such as stress strain curves, fatigue curves, welding processes, joint mechanics, FLD, welding windows, corrosion protection, etc.
In general, Volda will provide users the technical support for entire process from design to mass production of cold rolled special steel strip.
