钢板是用钢水浇注,冷却后压制而成的平板状钢材。是平板状,矩形的,可直接轧制或由宽钢带剪切而成。钢板按厚度分,薄钢板<4毫米,中厚钢板4~60毫米,特厚钢板60~115毫米钢板按轧制分,分热轧和冷轧。薄板的宽度为500~1500毫米;厚的宽度为600~3000毫米。

Steel plate is a kind of flat steel poured with molten steel and pressed after cooling. It is flat and rectangular, and can be directly rolled or cut from wide steel strip. According to the thickness of steel plate, thin steel plate < 4mm, medium thick steel plate 4 ~ 60mm, extra thick steel plate 60 ~ 115mm, steel plate rolling, hot rolling and cold rolling. The width of thin plate is 500-1500 mm; the width of thick plate is 600-3000 mm.

薄板按钢种分,有普通钢、合金钢、弹簧钢、不锈钢、工具钢、耐热钢、轴承钢、硅钢和工业纯铁薄板等;按用途分,有油桶用板、搪瓷用板、防弹用板等;按表面涂镀层分,有镀锌薄板、镀锡薄板、镀铅薄板、塑料复合钢板等。

According to the type of steel, there are ordinary steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron sheet; according to the purpose, there are oil barrel plate, enamel plate, bulletproof plate, etc.; according to the surface coating, there are galvanized plate, tin plate, lead plate, plastic composite plate, etc.

耐磨钢板:耐磨钢板(WearResistantSteelPlate)是指专供大面积磨损工况条件下使用的特种板材产品。常用的耐磨钢板是在韧性、塑性较好的普通低碳钢或者低合金钢表面通过堆焊方法复合一定厚度的硬度较高、耐磨性优良的合金耐磨层而制成的板材产品。另外,还有铸造耐磨钢板和合金淬火耐磨钢板。

Wear resistant steel plate: wear resistant steel plate refers to the special plate products specially used for large area wear conditions. The commonly used wear-resistant steel plate is made of a certain thickness of alloy wear-resistant layer with high hardness and excellent wear resistance on the surface of low carbon steel or low alloy steel with good toughness and plasticity by surfacing. In addition, there are cast wear-resistant steel plate and alloy quenched wear-resistant steel plate.

耐磨钢板的结构特点:耐磨钢板由低碳钢板和合金耐磨层两部分组成,合金耐磨层一般为总厚度的1/3~1/2。工作时由基体提供抵抗外力的强度、韧性和塑性等综合性能,由合金耐磨层提供满足指定工况需求的耐磨性能。

Structural characteristics of wear-resistant steel plate: the wear-resistant steel plate is composed of low-carbon steel plate and alloy wear-resistant layer, and the alloy wear-resistant layer is generally 1 / 3 ~ 1 / 2 of the total thickness. The matrix provides the strength, toughness, plasticity and other comprehensive properties to resist external forces, and the alloy wear-resistant layer provides the wear resistance to meet the requirements of specified working conditions.

耐磨钢板合金耐磨层和基板之间是冶金结合。通过专用设备,采用自动焊接工艺,将高硬度自保护合金焊丝均匀地焊接在基板上,复合层数一层至两层以至多层,复合过程中由于合金收缩比不同,出现均匀横向裂纹,这是耐磨钢板的显著特点。

The alloy wear-resistant layer of wear-resistant steel plate is metallurgically bonded with the substrate. Through special equipment and automatic welding process, the high hardness self-protection alloy welding wire is evenly welded on the base plate, and the number of composite layers is one to two or even more. In the process of composite, due to the different alloy shrinkage ratio, uniform transverse cracks appear, which is a significant feature of wear-resistant steel plate.

合金耐磨层主要以铬合金为主,同时还添加锰、钼、铌、镍等其它合金成份,金相组织中碳化物呈纤维状分布,纤维方向与表面垂直。碳化物显微硬度可以达到HV1700-2000以上,表面硬度可达到HRC58-62。合金碳化物在高温下有很强的稳定性,保持较高的硬度,同时还具有很好的抗氧化性能,在500℃以内完全正常使用。

The wear-resistant layer is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbides in the metallographic structure are distributed in fibrous form, and the fiber direction is perpendicular to the surface. The micro hardness of carbide can reach hv1700-2000 and the surface hardness can reach HRC58-62. The alloy carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.

耐磨层表现形式有窄道(2.5-3.5mm)、宽道(8-12mm)、曲线(S、W)等;主要以铬合金为主,同时还添加锰、钼、铌、镍、硼等其它合金成份,金相组织中碳化物呈纤维状分布,纤维方向与表面垂直。碳化物含量40-60%,显微硬度可以达到HV1700以上,表面硬度可达到HRC58-62。

The wear-resistant layer is mainly composed of narrow channel (2.5-3.5mm), wide channel (8-12mm), curve (s, w), etc.; it is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium, nickel, boron, etc. are added at the same time. The carbide in the metallographic structure is fibrous, and the fiber direction is perpendicular to the surface. The content of carbide is 40-60%, the microhardness can reach hv1700, and the surface hardness can reach HRC58-62.
