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 castedin t o slabs. The slabs are reheated and rolled i n t o 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.

钢板尺寸、外形、重量及允许偏差Dimension, shape, weight and tolerance
钢板尺寸、外形、重量及允许偏差满足《GB/ T709-2006热轧钢板和钢带的尺寸、外形、质量及允许偏差》的要求。
BP系列防护钢采用特殊热处理工艺制造,板形质量优异,整板不平度可以达到≤3mm/m。用户如对尺寸公差、不平度等有附加要求,

Dimension, shape, weight and tolerance satisfy GB/T709-2006 Dimension, shape, weight and tolerances forhot rolled steel plates and sheets
BP steels are manufactured by special heat treatmentprocess with superior shape and flatness within ≤3mm/m.Additional requirements concerning the dimension t olerance, roughness etc. should be confirmed bysupplier and be customer, and be specified in thecontract.
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%
