以含锌尘泥为原料的含碳球团强度及金属化率的影响因素

The Factors Influencing the Strength and Metallization Rate of Carbon-bearing Pellets Made of Zinc-bearing Dust and Sludge as Raw Materials

将含锌尘泥、铁精矿及粘结剂混合造成的含碳球团在1050～1250℃条件下还原，研究了不同粘结剂、不同温度对其强度及金属化率的影响。结果表明，以水玻璃为粘结剂的含碳球团具有较好的强度和金属化率。

The carbon-bearing pellets made of zinc - bearing dust and sludge, iron concentrates and additive of agglomerant were reduced at 1 000 - 1 200 ℃, the effects of different kinds of additive and reduction temperature on the strength and metallization rate of carbon - bearing pellets were studied. The result shows that the pellets will have high strength and metallization rate when water glass was used as additive.
