Basic information for heavy plate process

To comply with customer's various individual needs, XG manufactures pressure vessel plate from ingots & continuous cast slabs.

    Ingots take advantage of high compression ratio and single weight to make super width &thickness plates with high quality.

    Continuous cast slabs are produced by Voistalpine AG’s advanced equipment & technology using straight arc for multi-point bend and multi-point correction, dynamic slight pressure, gas-cool for the second cooling procedure and width adjustment on line.etc. Successfully address frustrations factors such as: central segregation of large cross-section slabs, loose and crack defect etc. All these help to improve surface quality and inside quality of plate made of slabs.

Steel making process of ingots

XG has two lines of furnace & converter in steel-making. Single weight of the heaviest ingot smelted by electric furnace is 54MT. It's enabled to produce mold ingots weighing 13.5, 20.5, 26.6,29,35,&45MT. Mold ingot cast of 54MT producible through the newest technology of water-cool process.

 

Metallurgical technology & equipment of converter attains 1st grade in China, producing mold ingots weighing 20.5,26.6,35&45MT.

Continuous casting slab

 

4 lines of continuous casting slab enable the production to be 5million metric tons.

 

 

XG has 3 lines for heavy plate, including 2lines for 3800mm width, with annual production 3 millions MT and 1 line for 5000mm width with 2 million MT designed capacity. XG aims on high-tech products and suitable for wide, thick & dedicated industrial plates. Range of dimensions: 6~350*1500~4900*6000~25000.

 

4X120MT combined blown converters, Max. unit capacity is 150MT, 1 standby

6X120MT LF label refining furnace with max. unit cap. 150MT

2X120MT VD vacuum refining furnace with max. unit cap. 150MT

2X120t RH vacuum treating devices with max. unit cap. 165MT

4 single-flow plate casters, annually producing 5million MT.

 

Rolling system & capacity

Max. Rolling force of blooming(BM) & finishing mill(FM) to be 10,000MT. Max. Opening degree of 5M BM to be 1100MM, rolling ingot with max thickness 1000MM.

Vertical roll configured at the exit of BM with max. Rolling force 800MT.

Opening  degree of BM rarely seen in China. Single weight to be 24MT for continuous slabs and 40MT for ingots.

 

Process & equipment of the 5000mm heavy plate was designed by SVAI and operated in Oct. 2010 with annual production 2 million MT, now in full operation. And the two 3800mm heavy plate lines are the most advanced mills in the world. SMS Sideman is the contractor of the on-line-controlling equipment and technology.  It ensures the stable performance of plate together with precisely controlled dimensions.

XG adopts the System Management theory, and  imported the most advanced equipments and technology from DANIELI, SVAI, SMS SIEMAG & SIEMENS, and besides, we use MES management system to ensure the  stable performance of plate together with precisely controlled dimensions.

 

3 normalizing lines with annual capacity of 1. 05 millions MT, configured with the longest 117M normalizing furnace in Asia.

1 quenching line with capacity of 100,000MT.

1 tempering line with annual capacity of 350,000MT.

1 car bottom furnace with annual capacity of 50,000MT.

 

 

 

 

XG’s mechanical & chemical testing centre was approved by CNAS in 2003. And reexaminated and approved  in 2008.

 

The centre is configured by Photoelectric direct-reading spectrometer, X-fluorescence optical analyzer, Inflated carbon/sulfur analyzer, ICPspectrometer, Nitrogen/oxygen combined tester, High temperature electronic almighty tensile testing machine, Servo controlled material testing machine, Fully automatic impact testing machine with metal swing hammer, Straight-fall hammer impact testing machine, Defect projector for impacted sample, Ultrasonic testing machine.etc. And all these world level testing equipments are operated by skilled staff.

 

XG’s test system is an automatic, purpose-complete and precise system.  We execute quick tests to molten steel, gas elements of slabs & plates and slag ingredients. We own 2 lines of spectral automated analysis system provided by Thermo Fisher , USA (modeless 2000-4460 ), 1 X-fluorescence’s spectrometer provided by  Thermo Fisher (model: 9900).  2 oxygen/nitrogen/argon analyzers provided by HDRIBA(Japan), 1 carbon/sculpture analyzer provided by ELTRA(Germany, model: CS800).
