一、概论 我国的热双金属生产发展,应追溯到我所附属试验厂——南星合金厂。该厂于52年试制成黄铜与因瓦合金组成的TB—6热双金属,时售价为800元/公斤,供应医疗器械工业作恒温干燥箱温度控制元件。58年后陆续试制成TB—3,TB—5等牌号的热双金属,至63年年产量已在12吨以上,成为我国唯一的生产热双金属的专业工厂,市场复盖率达90％以上。 First, an overview of China’s hot bimetallic production development, should be traced back to my affiliated pilot plant - Southern Star alloy plant. The plant in trial production in 52 years made of brass and Invar TB-6 thermal bimetallic, when the price is 800 yuan / kg, the supply of medical equipment for industrial oven temperature control components. After 58 years, it has successively trial-produced the hot bimetallics such as TB-3 and TB-5. By the year 63, its annual output has been above 12 tons, making it the sole factory that produces hot bimetal in China with a market coverage rate of 90 %the above.
