The hottest Siemens will provide Chinese enterpris

Siemens will provide Chinese enterprises with two arvedi endless strip production lines

the new continuous casting and rolling production line will enter the market of producing high-quality ultra-thin strip steel

the thickness of the strip steel produced will be as low as 0.8 mm

the annual output of the plant will be as high as 5.2 million tons

this order is as high as hundreds of millions of euros

Siemens Metallurgical Technology Department recently received an order for two arvedi endless strip production lines (ESP) from a Chinese steel enterprise Orders for. Compared with the traditional casting and rolling process, which is a large-scale precision testing instrument that gives full play to the respective strengths of the motor, the energy consumption and related costs of the new casting and rolling equipment will be reduced by 45%, which means that carbon dioxide emissions will be significantly reduced. The designed annual output of the new equipment is 520 tons (2.6 million tons for each production line), which can produce high-quality ultra-thin hot-rolled strip with a maximum width of 1600 mm and a minimum thickness of 0.8 mm. In addition, the new equipment can also produce various grades of carbon steel, high strength low alloy steel (HSLA) and dual phase steel. The new casting and rolling equipment will be put into a Chinese steel plant under construction. The steel plant is scheduled to start production in 2015. In the installation, commissioning and operation of the factory, most of these bonds are hydrogen bonding surfaces. Technicians from acciaieria arvedi company in Italy who serve the existing ESP equipment will provide technical support and assistance to customers

the two newly ordered arvedi ESP production lines will help this Chinese steel enterprise produce high-quality thin strip steel products, so as to better serve the highly attractive local and export markets. In addition, compared with the traditional casting and rolling production line, this 180 meter long production line occupies a more compact area

Siemens will be responsible for the engineering design of arvedi ESP production line and provide relevant mechanical equipment, medium control system, process software package and automation system. The whole production line is controlled by the integrated basic automation system (L1) and process optimization automation system (L2), and all casting and rolling operations are fully regulated. The scope of supply of this project also includes a comprehensive set of training and assistance services, including providing theoretical and practical operation training for customer operators with reference to the existing ESP production site of acciaieria arvedi in Cremona, Italy, and providing support to customers in reaching production by experts from acciaieria arvedi

on the arvedi ESP production line, hot rolled steel coils are produced directly by a continuous casting and rolling mill through continuous production process. The production line will first cast thin slabs, then roll them into intermediate slabs with a thickness of 10 to 20 mm in a three stand heavy reduction mill at the end of the continuous caster, then heat them in an induction heater, then roll out the target thickness through a five stand finishing mill, and the strip steel enters laminar cooling for cooling. The endless continuous strip steel is finally cut by a high-speed shear located in front of the underground coiler and rolled into a steel coil with a weight of 32 tons

the process layout and expected results of the new equipment are based on the operational performance of the existing ESP production line of acciaieria arvedi company. The existing production line has been running well since 2009. Due to the unique mold design and installed process software package, its caster has high stability, and the breakout rate is only 0.07%. Because arvedi ESP production line adopts endless strip steel production mode, the operation of repeatedly threading each rolling frame is omitted, which is also the basis for producing ultra-thin strip steel with the thinnest thickness of 0.8 mm. The rolled steel of all rolling lengths fully meets the requirements of geometric tolerance. In addition, endless strip production can also ensure that the produced strip is consistent in microcrystalline structure, grain size, yield strength and tensile strength. Since the strip steel is always under tension, the steel stacking rate is lower than 0.1%. At the same time, there is no need to use a lead screw to cut the head and tail ends of strip steel 5 The assembly quality is cut, so the yield can be as high as 98%
