4 Trends of the Future Steel Rolling Industry
by Luoyang Judian Professional Steel Casting and Rolling Equipment MThe technological progress of the world's steel rolling industry
mainly focuses on the shortening and simplification of the production process,
resulting in high-quality rolled products, diversified varieties and
specifications, and computerized control and management. In the future, the
steel rolling process and technology still need to be developed in the
following aspects.
Casting and Rolling
Integration
The use of rolls for steel production, because of its continuous,
efficient, easy to control by computers, will continue to be the mainstream
technology for steel forming in the iron and steel industry for a considerable
period of time in the future. But the connection technology between the pre-and
post-rolling processes must make great progress.
In the 20th century, due to the development of continuous casting,
the blooming process has been phased out. The thin strip steel produced by
continuous casting technology is directly cold-rolled, and the continuous
casting and hot-rolling processes are combined into one. The integration of
casting and rolling will make the rolling process more compact. At the same
time, the integration of casting and rolling with low energy consumption and
low cost is also the development direction of bar, wire and profile production.
Clean Rolling Process
In the hot rolling process, the oxidation of steel not only consumes
steel and energy, but also brings environmental pollution and brings
difficulties to deep processing.
Therefore, both the low-oxidation combustion technology and the
application of low-cost hydrogen will become the basic technologies for heating
billets without oxidation. Pickling and descaling is the biggest source of
pollution in cold rolling production. The newly developed acid-free cleaning
descaling technology can make the surface of strip steel free of oxides, smooth
and have a metallic luster. The emergence of two new technologies,
non-oxidation (or low oxidation) and acid-free descaling (iron scale), will
also make the steel rolling process cleaner.
Flexible Rolling Process
The application of pressure width adjustment technology and strip
shape control technology in strip hot rolling production has realized the free
regulation rolling of strip width. The application of rough and medium rolling
flat roll technology for the production of rods and wires has realized the free
rolling of some specifications of products. Cold bending and welding pipe
machines are also available for free-to-size production. These new technologies
make the rolling process flexible.
Application of High
Technology
The main feature of the significant progress made in steel rolling
technology in the 20th century is the application of information technology.
The application of high and new technologies such as automatic control of plate
shape, free-schedule rolling, high-precision and multi-parameter online
comprehensive testing has brought rolling steel production to a new level.
The control of the rolling mill has begun to change from computer
model control to artificial intelligence control, and with the development of
information technology, the optimization of the production process will be
realized, the inventory rate will be reduced, the capital turnover will be
accelerated, and finally the cost will be reduced.
