摘要: 以缅甸达贡山红土镍矿为矿石原料,利用其冶炼时产生的高温炉渣制备造纸用无机矿物纤维,试验结果表明,在冶炼时添加的石灰量为矿石质量的10%,制纤时炉渣温度为1 500~1 600 ℃、离心成纤机转鼓表面线速度为10 835 m/min、高温炉渣流量为2 800 kg/h条件下,高温炉渣成纤率可达75.30%~75.38%。用制得的无机矿物纤维代替部分植物纤维试制瓦楞芯纸和箱板纸,结果表明,两种纸品中无机矿物纤维最大使用量分别可达35%和40%(按无机矿物纤维与植物纤维的质量比计)。研究成果为镍铁冶炼渣的高效利用提供了新途径

Abstract: With Taguang Taung laterite nickel ore in Myanmar as raw materials, inorganic mineral fiber used in papermaking was prepared with high-temperature slag. The test results showed that under conditions of the amount of lime added in smelting occupying 10% of the ore by mass, the temperature of the slag at 1 500 ~ 1 600 ℃, the surface speed of centrifuge fiber-forming drum 10 835 m/min, and high temperature slag flow of 2 800 kg/h, fiber-forming rate of high temperature slag reached 75.30% ~ 75.38%. The prepared inorganic mineral fibers are used to replace parts of plant fiber to produce corrugated medium and liner board. The results showed that maximum amount of inorganic mineral fibers in two kinds of paper reached up to 35% and 40% respectively (by the mass ratio of inorganic mineral fiber and plant fiber).The research provides a new way for efficient utilization of nickel-iron smelting slag.
