梅山精矿粉的铁矿物中含有较多的菱铁矿,脉石中含有粘土矿物,精矿粉水分高、粘性大、软融温度低,软融区间宽,在烧结过程中料层阻力大,透气性差,垂直烧结速度慢。研究表明,适当控制混合料水分,加强制粒,使混合料具有良好的粒度组成(特别是白云石粒度应尽量细,其中大于3mm的应在5％以下),并且应减少白云石配入量(以1988年配比量的1/2为宜)。这样可得到优质烧结矿。 Meishan concentrate powder iron ore contains more siderite, gangue clay minerals, concentrate powder high moisture, viscosity, low melting temperature, soft and wide range, the sintering process in the layer resistance Large, poor breathability, slow vertical sintering. Studies have shown that the proper control of the mixture of water to strengthen the granulation, so that the mixture has a good particle size composition (especially dolomite should be as fine as possible, of which more than 3mm should be less than 5%), and should reduce the amount of dolomite (In 1988 the ratio of 1/2 is appropriate). This gives a good quality sinter.
