I46S型热双金属用于彩色显象管荫罩温度补偿弹簧片,全国第一家彩显管引进线4400厂要求16项指标附合购买标准,并尽量接近日本样品水平。其中尤其要求具有稳定的弯曲常数弹性模量、反复弯曲、扭曲、硬度、放气量等主要性能,以及接近日本样品水平的表面质量,尺寸公差。另外要求成品卷重(中间无焊缝)在40公斤以上,卷内径600mm以上。
I46S-type hot bimetal for color CRT shadow mask temperature compensation spring piece, the country’s first color tube 4400 introduction of color lines require 16 indicators attached to purchase standards, and try to approach the level of Japanese samples. In particular, it requires stable bending constants such as elastic modulus, repeated bending, twisting, hardness and deflation, as well as surface quality and dimensional tolerances close to the Japanese sample level. In addition, the finished product is required to have a heavy weight (no weld in the middle) of 40 kg or more and an inner diameter of 600 mm or more.
