    Wu Yang Iron&Steel

    Material introduction
    1:PRODUCING PROCESS

     Raw Material(Carbon steel&pig iron&ore)→Electric
     Furance(90MT/100MT Furance) →LF Furance(Refining molten steel
     handling)→Vacuum Treatment(VD/VO Furance)→Casting,Serial
     Casting →Ingot Re-Furance Treatment→ Heating(Serial Heating Furance)
     →Steel Producing(4400mm&4200mm
     machine)→Exploration&Monitoring Test→Steel Heat Treatment
     →Hardness Test→Steel Appearance Quality Inspect

    2:PRODUCTION FEATURE

     1):First-class steel-making technology and equipment to ensure the purity
     of steel. Featured scrap and other raw materials in order to reduce the
     content of external debris and gas. Refining the use of ultra-high power
     electric furnace and the secondary refining; In order to ensure that the
     inherent quality of steel plate, static VD vacuum furnace treatment,
     calcium treatment process measures to improve the purity and
     composition of the steel group quasi-stable, the use of micro-alloying
     technology, further improve the steel characteristics
    2):We have the largest production of steel ingot and continuous casting
     technology.
    3)Adopting electroslag fuance to improve the quality and grade of steel
    4)We have largest width and extra-specification production technology
    5)Owning the best heating treatment technology
    6):Complete quality inspection tools.Full automation and on-line
     automatic detection technology, rolling line set up in the process control
     temperature, thickness, width measurement, measuring, measuring device
     equality. Print Online automatically signs, automatic ultrasonic flaw

    3:Wearable steel category

    1):Standard series:Wu steel has 2 standard series and 4 top-class
     standard series.
    2)Top-Class standard series
     Application:This kind steel is used for general processing of wear-
     resistant parts and exposed structures,e.g.Cold bending,welding,cutting and
     machining.
    A):General wear-resistant steel plates:We can produce the max thickness is 100mm,and guarantee the hardness.Meanwhile,we can ensure the impact
    toughness.On behalf of:NM360,NM400(A,B,C classes.)
    B)Ultra wear-resistant steel plates:This kind steel requires for a more
    sustainable life,thus reducing the operating costs.Without more welding
    and forming characteristics of the expense under the premise of high
    performance wear-resistant.e.g:NM450,NM500 and so on
    C)High toughness steel plate:In regularly,under -20 degree,The
    toughness can not be ensured .But Wu steel is successed in producing this
    kind high toughness steel,and can guarantee the impact and thoughness
    under low temperature(-40degree).E.g:NM400,NM360(D,E)
    D)High weldability steel

    4:Features of wear-resistant steel

    A):Reducing steel plate weight:Steel plate is based on a number of
    alloying elements required for the addition, the design of high-strength
    low-alloy series, through the plate the way a special heat treatment to
    improve the strength level of steel so that they are to correspond to a
    variety of high hardness (wear resistance). As a result, the weight of
    structural parts can be reduced significantly

    B)Welding:If due consideration is given to the general rules for
    welding,this steel is weldable both manually and automatically.To prevent
    cold cracking in the welded joints only welding consumables giving welds
    of very low hydrogen content should be used.Preheating is not generally
    necessary for welding with austenitic filler metals,but it may be necessary
    for welding with ferritic filler metals.The preheat temperature level for
    welding depends on the plate thickness and the residual stress state of the
    structure.The working temperature should not go beyond 250 degree.

    C):Toughness:Through strict control of chemical composition, reduce the
    maximum content of harmful elements in steel, heat treatment conditions
    for a reasonable choice to make steel with good toughness. One can,
    therefore, against brittle wear-resistant structural damage, to build a high
    degree of reliability of structural

    D):The apperance is beautiful and smoothy

    E):Good Processablility:As a result of the performance of the control plate
    even with the best performance, and to ensure good toughness.bending

    and therefore drilling, cutting, etc. are excellent machining performance
    F):Specification:(3mm-100mm)*(1500mm-3300mm)*13000mm

    5:Application and Recommend the use of the field

     The steel may be used at the discretion of the purchaser for wear exposed
     structure.For example:excavationg,mining and earth moving
     machinery,truch dump bodies,conveying,crushing and
     pulverizingequipment,scrap presses and paving moulds.

    6:Introduction of NW450,Standard:WYJ101-2009

     The average of hardess is around 450HB.Mechanical porperties is
     obtained by heat treament.Cold-formed steel has a good
     performance,used in anti-wear condition,Meawhile,it has good processing
     performance,and weldability.
