我国能源利用率,热效率低,其浪费可怕惊人。如日本与我国每年均消耗六亿吨标煤,但其总产值却高于我们3-4倍。上述局面的产生,与工业部局的科学性、合理性、综合开发及专业化加工生产程度有关。据报导国外凡有共性的生产工序、加工、工种等均早以组建成低能高效的专业化生产中心。如工装模具制造专业化,国外已达80%以上,而我国仅有10%;集中供热苏联在1976年就已实现66%,而我国1983年仅有5%;热处理专业化程度,美国1972年对894个机床企业调查,已实现93.9%,而我国尚未普及;铸造专业化国外已达60%,而我国在机械行业仅为17.7%;电镀专业厂日本有4500家;余热利用率日本为57%,美国为51%,西欧为45%,我国为30%。
China’s energy efficiency, low thermal efficiency, the horrifying waste of amazing. For example, Japan and China consume 600 million tons of standard coal every year, but their total output value is 3-4 times higher than ours. The above situation is related to the scientific nature and rationality of the Bureau of Industry, the comprehensive development and the level of specialized processing and production. It is reported that all foreign common production processes, processing, and other types of work are as early as the formation of low-energy and efficient professional production center. Such as tooling mold manufacturing specialization, foreign countries have reached more than 80%, while China is only 10%; Centralized Heating The Soviet Union in 1976 has been achieved 66%, while China only 5% in 1983; degree of heat treatment specialization, the United States 1972 The survey of 894 machine tool enterprises in the year has achieved 93.9%, but our country has not yet popularized; the casting specialization has reached 60% in foreign countries while China only has 17.7% in the machinery industry; the electroplating professional factory has 4500 in Japan; the utilization rate of waste heat in Japan is 57% in the United States, 51% in the United States, 45% in Western Europe and 30% in our country.
