1985年以来,我厂在全厂八台烧结机上全部推广应用了节能型可塑料点火保温炉,使点火煤气消耗比去年同期降低了15%;为了进一步降低点火煤气消耗,借鉴日本新日铁低温低负压点火这项节能新技术,我们于1985年5月7～9日在一烧车间和三烧车间进行了工业性生产试验。试验分两个阶段进行;第一阶段进行低温点火试验;第二阶段 Since 1985, our factory has all applied and popularized the energy-saving plastic ignition holding furnace in the entire factory of Yantai Sintering Machine, reducing the ignition gas consumption by 15% over the same period of last year. In order to further reduce the consumption of ignition gas and drawing lessons from Japan’s Nippon Steel’s low temperature Low-pressure ignition of this energy-saving new technology, we in May 1985 7-9 in a burning workshop and three burning workshop for industrial production test. The test is carried out in two stages; the first stage is a low temperature ignition test; the second stage
