【摘要】：刹车盘是高铁制动系统中的重要部件,其铸造质量决定着高铁的制动效果。通过对铸件进行机械加工,发现在树脂砂叠箱造型生产条件下,摩擦面缺陷类型主要表现为夹渣缺陷。通过缺陷成因分析和工艺改进,摩擦面夹渣缺陷大幅度减少,刹车盘成品率达到99.8%,内在和外在质量显著提高,满足了外商对高铁刹车盘的综合质量要求。
[Abstract]:Brake disc is an important part of high-speed braking system. Its casting quality determines the braking effect of high-speed railway. By machining the castings, it is found that the main types of friction surface defects are slag inclusion defects under the production conditions of resin sand stack box. By analyzing the causes of the defects and improving the process, the defects of slag inclusion on the friction surface are greatly reduced, the finished product rate of the brake disc reaches 99.8, and the internal and external quality is improved significantly, which meets the comprehensive quality requirements of the foreign investors for the high-speed iron brake disc.
