　　宝钢依靠自身装备水平和技术力量，在国内率先研制成功BP系列高性能装甲防护钢，厚度范围为2-12mm。该产品采用热轧卷板

　　作为基板进行热处理，抗枪弹性能优越，抗破坏性冲击能力强，性能均匀稳定，板形和表面质量好。本系列产品适用于运钞车、装甲运兵车、

　　押解车辆、贵宾车辆、防盗门、银行柜台防护板、保险柜、盾牌、钢盔等。

　　Baosteel protection(BP) steels with 2 to 12mm in thickness were firstdeveloped at Baosteel in China by employing Baosteel's own equipments

　　and Technologies. The steels were heat treated with hot rolled plates togain excellent ballistic performance, uniform property, good shape and

　　surface quality.The steels can be used for applications where high ballistic performanceis required, such as armored cars, armored personnel carriers, escortvehicles, VIP cars, security doors, bank counter shield, strongbox,shields, helmet ,et al.

　　热轧装甲防护钢

　　生产工艺流程:BP系列防护钢采用氧气转炉冶炼镇静钢，经过二次精炼后进行连续铸造，连铸坯送热轧厂再加热并采用控轧控冷工艺轧制成卷，经强

　　力矫直切板后进行热处理，性能质量检测合格后准发交货。交货状态:BP系列热轧防护钢可采用控轧、淬火、淬火加回火等状态交货。

　　加工配送服务:根据用户需求，钢板可采用抛丸、涂漆表面预处理方式交货。可提供钢板下料、折弯、构件加工等延伸服务。

　　Manufacture process: The steel is made in oxygenconverter, fully killed, secondary refined and castedinto slabs. The slabs are reheated and rolled into coil inTMCP rolling process. After powerful leveling, cutting,heat treatment, and inspection, the BP plates aredelivered in sheets.Delivery condition: TMCP, quenched, quenched andtempered etc.Processing and distribution service: Accordingto customers' requirements, steel plate can bedelivered with pretreatment such as blasting, paintingetc. Additional services e.g., blanking, bending andmachining are also provided.

　　枪击标准及防护级别Ballistic standards and protection grades

　　BP系列防护钢抗枪弹性能优越，抗破坏性冲击能力强。参照的主要标准有:GA 164-2005、GJB 1694A-2000和GJB 59.18-1988。

　　BP steels have excellent ballistic performance and goodimpact properties.Standards: GA 164-2005, GJB 1694A-2000 and GJB59.18-1988.

　　钻铣加工Drilling

　　BP系列防护钢硬度高，机加工难度相对较大。钻孔加工一般应采用高速钢或陶瓷硬质合金钢钻头。为保证批量钻孔作业时的高效和精确，推荐使用

　　高速合金钢（HSS-E）或含钴高速合金钢（HSSCo）钻头。铣削加工时应确保夹紧工件，建议采用宽矩铣刀，平面铣刀的材质可选用硬质合金涂层、陶瓷合金等，端面铣刀可选用硬质合金、含钴高速合金钢等，尽量避免采用组合铣头，平面铣的切削宽度应为铣头直径的75％－80％

　　Either high speed steel or cemented carbide drillscan be used for drilling. To ensure the efficience andaccuracy, micro-alloyed(HSS-E) or cobalt-alloyed(HSSCo)drill is recommended.Work piece should be clamped tightly while milling andwide-space milling cutter is recommended. Carbide

　　coating, ceramic alloy etc. can be used as the materialfor flat cutter, and hard alloy, cobalt-alloyed high speedsteel etc. for end cutter, combined milling head is notsuggested. Cutting width of flat milling is 75-80% of thediameter of milling head.

　　折弯加工Bending

　　当用户需要对BP系列防护钢进行冷成形时，工作时须注意钢板的回弹等的影响，钢板强度越高，其回弹越大。钢板的最小折弯直径不能小于供货技术

　　条件中双方商定的冷弯直径。BP500折弯时，最小折弯半径应不小于板厚的8倍；BP440折弯时，最小折弯半径不应小于板厚的5倍。折弯加工时，不能采用冷切割的方式下料。

　　When cold forming is needed for BP steels, closeattention need to be paid to the springback. Highstrength usually means large springback. It should benoted that the minimum bending diameter can not besmaller than that confirmed in the delivery conditions.The minimum bending diameter for BP500 has to be 8times larger than the plate thickness; the correspondingbending diameter for BP440 has to be 5 times largerthan the plate thickness.Mechanical cutting is not recommended for bendingparts.

　　切割Cutting

　　BP系列防护钢适用于水射流切割、激光切割和等离子切割。如果设备剪切能力满足，也可以采用机械剪切来进行加工。推荐使用水射流切割，此种切

　　割方式能够保证切割边缘的防弹性能。

　　BP steels are suitable for waterjet, laser and plasmacutting. Provided that the cutting blades hard enoughand the equipment stiffness high enough, mechanicalcutting could be an optional. However, waterjet is highlyrecommended, as the ballistic properties of the cut edgecan be guaranteed.

　　热加工Hot working

　　不建议对BP系列防护钢板进行热加工。如果需要对钢板进行相应的热处理，请与宝钢产销研小组联系。

　　Heat treatment is not recommended. If a temperingprocess is needed, please contact the technicalcustomer service for further assistance.

　　焊接Welding

　　BP系列防护钢可采用常用的焊接方法进行焊接。选择焊接材料时，推荐使用奥氏体焊接材料或低强度的铁素体焊接材料。如果焊接接头强度是重

　　要的性能要求时，也可以采用强度较高的铁素体焊接材料。

　　BP steels can be welded with conventional weldingmethods. Austenitic or low strength ferritic weldingconsumables are recommended. High strength ferriticwelding consumables can also be used if the strength ofwelding joint is important.
