5 PRODUCTS AND PROCESS FEATURES Product delivery capability Many delivery conditions can be available: as-rolled, control rolled, TMCP, direct quenched (DQ), direct quenched and tempered, normalized, quenched &

tem- pered, etc. Max. thickness: 200mm;

Max. width: 4800mm;

Max. length: 25m;

Max. unit weight: 22.5 tons And high-strength steel plate with yield stress of 1300MPa is also available in Baosteel. High purity of steel With advanced steel-making equipment and technology, high purity of the steel plates can be ensured by desulfurization of liquid iron, converter dephosphoriza- tion and ladle refining (RH-MFB, LF, RHOB, KIP/CAS). Excellent metallurgical properties of the slab Center segregation, inclusion, porosity and internal crack can be effectively con- trolled by electromagnetic stirring and soft reduction technique. Excellent surface quality Depth of scale on the surface of steel plate ≤0.2mm;

Area with defect depth from 0.05mm to 0.2mm ≤2%;

Surface roughness after shot-blasting ≤70um. Plate shape control technology CVC plate profile control technique. Multi-point setting and adaptation between passes can be implemented by high accuracy setting model. Highly-accurate dimension control The finishing mill stand is equipped with absolute AGC and closed-approached gauge meter type monitor AGC functions to improve thickness control accura- cy. Thickness variation in length is less than 0.5mm. For ordering, the minimum thickness unit is 0.1mm, and the minimum length and width unit is 1mm.

6 产品介绍 INTRODUCTION OF MAIN PRODUCTS 耐磨钢产品系列 宝钢厚板耐磨钢目前主要分为

9 种产品:2 种基础型产品、4 种合金型产品和

3 种易焊接型产品,能够满足用户广泛要求. 基础型系列 本系列产品主要满足硬度要求,化学 成分较为简单,合金含量较少. 合金型系列 本系列产品与基础型产品相比含有较 多的合金元素,除了满足硬度要求外, 还可满足低温冲击韧性要求. 易焊接型系列 本系列产品与基础型和合金型产品相 比碳当量(CEV)更低,更易于焊接. A Variety of Available Grades A total of

9 grades are available: the basic series with

2 grades of hardness, and the alloy series with

4 grades, and the easy weld- ing series with

3 grades, providing a complete product line that can meet a wide range of applications. Basic Series This series consists of grades pro- duced with the main emphasis on their hardness levels, the chemical composition being basically simple while the addition of other alloying elements is restrained. Alloy Series This series contains alloying elements in greater quantities than the basic series. Both the prescribed hardness and low-temperature toughness are guaranteed. Easy Welding Series This series contains restrained con- tents of carbon and alloying elements. The value of CEV........
