The 310 zed beam is mainly used for manufacturing the automotive frame at the bottom of railway freight car and oil tank truck, so the requirements of its corrosion resistance, strength and surface quality are extremely strict as well as the surface defects could directly affect its service life. Its main surface defects include local dent at shoulder, bracing wire and roll marks. The amount of main defects is significantly decreased by taking such measures as optimizing roll pass design of UR (universal rolling) mill as well as improving guide fittings of BD2 (second breakdown) mill and CCS (compact cartridge stand) mill so that the quality of 310 zed beam is improved, which could meet the development demands of railway heavy haul traffic.

310乙字钢主要用于铁路货车和油罐车底大梁的制造,对其耐腐蚀性、强度和表面质量的要求极为严格,表面缺陷会直接影响其使用寿命。310乙字钢表面缺陷主要包括塌肩、拉铁丝和轧痕,通过采取优化轧机UR孔型设计、改进粗轧机BD2和精轧机CCS导卫装置等措施,主要缺陷数量明显下降,310乙字钢产品质量得到了提高,满足了铁路重载发展的需求。

310乙字钢主要用于铁路货车和油罐车底大梁的制造,对其耐腐蚀性、强度和表面质量的要求极为严格,表面缺陷会直接影响其使用寿命。310乙字钢表面缺陷主要包括塌肩、拉铁丝和轧痕,通过采取优化轧机UR孔型设计、改进粗轧机BD2和精轧机CCS导卫装置等措施,主要缺陷数量明显下降,310乙字钢产品质量得到了提高,满足了铁路重载发展的需求。

310乙字钢  /  表面质量  /  提高

The 310 zed beam is mainly used for manufacturing the automotive frame at the bottom of railway freight car and oil tank truck, so the requirements of its corrosion resistance, strength and surface quality are extremely strict as well as the surface defects could directly affect its service life. Its main surface defects include local dent at shoulder, bracing wire and roll marks. The amount of main defects is significantly decreased by taking such measures as optimizing roll pass design of UR (universal rolling) mill as well as improving guide fittings of BD2 (second breakdown) mill and CCS (compact cartridge stand) mill so that the quality of 310 zed beam is improved, which could meet the development demands of railway heavy haul traffic.
