根据煤矿工业对左旋锚杆钢和右旋锚杆钢的使用要求,水钢以建材螺纹钢20MnSi为基础,设计开发了MG335和MG335Y锚杆钢,制定了化学成分、力学性能以及Φ16~20mm规格的外形尺寸等内控标准。通过合理的冶炼、轧制、冷却工艺,保证了锚杆钢的产品质量,成品锚杆钢的化学成分、力学性能、外形尺寸等技术指标均符合产品设计要求,满足煤矿工业的使用要求。
According to the requirements of coal industry for the use of left-handed anchor steel and right-handed anchor steel, the design and development of MG335 and MG335Y anchor steel are based on the 20MnSi steel rebar, and the chemical composition, mechanical properties and Φ16 ~ 20mm specifications External dimensions and other internal control standards. Through the reasonable smelting, rolling and cooling process, the product quality of the anchor steel, the chemical composition, mechanical properties and overall dimensions of the finished steel are all in line with the product design requirements to meet the requirements of the coal mining industry.
