Label:(标签) The foundry is responsible for marking with a design number,charge number and a continues serial number according to CUSTOMER notifications on the drawings.Full traceability is demand.根据用户图纸中注明的设计数字,指示数字和一系列的数字,铸造商有责任将这些数字标记在铸件上.可追溯性是必要的.
Manufacturing:(制造加工) The method of manufacturing the SG-iron castings shall be left to the discretion of the foundry.球墨铸铁的加工制造方法由铸造商决定.
A detailed specification of the manufacturing method including casting design,pattern manufacture,moulding technique,mould surface coating technique,graphite spheroidizing treatment,any heat treatment etc.must be forwarded to the purchaser.加工制造方式的详细说明要附送采购商,说明包括:铸造设计,模具加工制造,浇铸工艺,铸件表面工艺,石墨球化处理,任何热处理等.
Test casting:铸件测试 In case of first-time manufacturing of a specific component or in case of any modification of the component and/or the specified manufacturing method,a test casting must be approved by the purchaser.一个特殊部件首次铸造或任何部件修改和/或制造方法的改变的情况下,铸件测试要得到采购商的批准.
A detailed measuring report of the dimensions of the test casting must be forwarded to the purchaser.测试铸件尺寸的详细测量报告要附送采购商.
Sampling and testing 1):取样样和测试1)Chemical composition,microstructure and mechanical properties incl.Brinell hardness must be tested on cast-on samples from each casting.Two samples each casting,one position at the highest section thickness and one position at the lowest section thickness.
化学组成,微观结构和机械性能,包括布氏硬度必须在来自每个铸件的取样测试.每个铸件两个取样:一个位置在厚度的最高点,一个位置在厚度的最低点.
Sampling and testing 2):样本和测试2 )Additionally the microstructure and Brinell hardness must be tested on two “Brinell knob” (ø25x30mm),positioned on the thinnest and thickest wall thickness.
The additional demand can only be avoided by a written acceptance from CUSTOMER quality department.
此外微观组织和布氏硬度必须用两个布氏探针来测量,位置在壁厚的最薄处和最厚处,此附加要求可通过客户质量部门的签收来取消.
