What are the Main Safety Technologies for Steel Rolling?

Steel rolling is a method of pressure processing that can be processed to obtain the desired shape and improve the internal quality of the steel. So what are the main safety technologies for steel rolling? Below is the relevant information.

• Rapid cooling technology for plate rolling, using internationally advanced high-density laminar flow cooling device to improve the production of special steel plates by controlled rolling control cooling process in medium and heavy plate production, and improve the mechanical properties of steel plates.
• Controlled rolling and controlled cooling technology for rebar production, through the specially designed cooler to achieve temperature controlled rolling between the inter-stand and inter-unit rolling, so as to improve the strength and toughness of the rebar.
• Cold rolling, hot rolling, plate shape control technology, including design and optimization of roll shape; strip steel shape on-line detection, signal recognition and shape evaluation; shape control strategy, pre-set, feedforward and feedback mathematical models.
• Hydraulic AGC technology, which adopts high-performance hydraulic APC and AGC control system with fast response speed and high control precision. It is replacing electric AGC as a new rolling mill and a new rolling mill technology.
• Complete equipment and technology of double-strand reversible cold rolling mill. This technology selects different rolling passes according to the material, specifications and production process conditions of the rolled strip so that the rolling mill can flexibly adapt to the belt in a larger range. The change of steel material, specification and coil weight, the high precision of the product, the development of precision strip and non-ferrous foil strip.
• Hot-rolled narrow strip steel production equipment and process technology, close to the broadband steel in the process and equipment, replace the looper oscillator and vertical coiling with laminar cooling and horizontal coiler, and increase the high pressure water before the roughing mill Descaling, the surface quality and performance of the strip steel are significantly improved, and the coil weight is increased to 1-2 tons.
• On-line inspection system for surface quality based on image processing. The system uses CCD camera to collect the surface image of the product on the production line, and analyzes and processes the image in real-time through image processing and pattern recognition algorithm to detect whether there is a defect on the surface of the product, obtaining the size, location, type, grade and other information of the defect, so as to achieve the purpose of online evaluation and control of the surface quality of the product.
• Steel product development and performance optimization techniques, including the influence of process parameters on the forming properties of IF steel; research on ultra-fine grain and high-strength pure steel; research on high-strength micro-alloy (Ti, Nb, V, B) steel.
• Rebar and wire rod size online detection system analysis software package, this package WRODES is developed by C++. The system installation is convenient and fast, running stably and reliably with good human-machine interface. It can support automatic report generation and printing with statistical analysis and historical record playback, query, and other functions.
• The application of finite element simulation in the metallurgical industry, using the general finite element software ANSYS, the volume forming and heat treatment analysis finite element software DEFORM and the thin sheet forming analysis software DYNAFORM for secondary development, enabling new product development and existing Process improvements are based on a more scientific and reliable basis.
