位于浙江温州乐清的浙江天盛双金科技有限公司向无锡南宝机械一次性订购了三套复合轧机，于今年5月28日顺利投产。Zhejiang Tiansheng Shuangjin Technology LTD. ordered three sets CRM for composite material, put into operation successfully on May 28, 2020 at Wenzhou, China.

这些550AGC复合轧机将Fe，Cu，Mn，Ni四种材料通过轧制粘合成复合材料带卷，轧制后的带卷经过切边，退火，送由配套的四辊、八辊AGC轧机继续轧薄，最终制成成品。其成品广泛应用于各类断路器，热继电器，空气开关等电器的热双金属原件。

AGC compound rolling mills are able to bond materials of Fe, Cu, Mn, and Ni into composite material coils by rolling. After being trimmed and annealed, composite strip is sent to the four-hi and eight-hi AGC mills to achieve thinner specification, and finally become finished products. Its finished products are widely used in thermal bimetallic originals of various circuit breakers, thermal relays, air switches and other electrical appliances.
