一、前言我国的硬质合金厂,除两个大厂外,包括个别研究所约占91%属中小型厂(后简称中小厂)。从1985年至今,我国硬质合金产量有五次较明显的起伏,尤其是1981年到了谷底,大半小厂关停并转。据统计,1973年我国有硬质合金厂170余家,现存中小厂只占约25%。留下的中小厂大多数经受几次考验,颃强地生存下来,且有不同程度的发展。
I. Introduction China’s cemented carbide plant, in addition to two major manufacturers, including individual research institutes account for about 91% of small and medium-sized factories (hereinafter referred to as small and medium-sized factories). Since 1985, China’s carbide output has five obvious ups and downs, especially in 1981 to the bottom, most small factories shut down and turn. According to statistics, there were more than 170 cemented carbide plants in China in 1973, accounting for only about 25% of the existing small and medium-sized plants. Most of the remaining small and medium-sized factories survived several tests and survived with varying degrees of development.
