1977年2号高炉技术改造时,在上料系统中采用了惯性共振式概率筛。对入炉前的烧结矿和焦炭分别进行筛分,其中烧结矿用筛12台,焦炭用筛6台。该筛在我厂已使用了六年,现将其使用情况介绍如下。一、筛子性能好,炉料粉末少,合格焦损失少普通振动筛和滚筛设备复杂,筛网容易磨损,更换频繁,维修工作量大,很难保证所筛烧结矿或块矿中粉末的稳定性。滚筛筛分焦炭时,滚片对焦炭有再碎性,随着滚片
In 1977 2 blast furnace technological transformation, in the feeding system uses the inertia resonant probability sieve. The sinter and coke before entering the furnace are respectively screened, of which 12 sinter screens and 6 coke screens are used. The sieve in our plant has been used for six years, the use of the situation are described below. First, the sieve performance is good, less charge powder, less qualified coke loss ordinary vibrating screen and rolling screen equipment complex, easy to wear screen, frequent replacement, maintenance workload, it is difficult to ensure that the sintered sinter or lump ore powder stability Sex. Rolling sieve coke, the rolling re-coke on the crushing, with rolling
