原燃料性质及其对烧结过程和质量的影响含铁原料精矿粉是含铁贫矿经过细磨选矿处理，除去了一部分脉石和杂质使含铁量提高的极细的矿粉。在烧结生产过程中，除了精矿粉外，往往还添加一些其它的含铁原料（如高炉返矿、铁皮和富矿粉等），这样做有两个目的，一是为了增加烧结混合料成球核心，改善混合料的透气性，提高烧结机利用系数，降低烧结矿成本。二是为了提高烧结矿的品位，为高炉顺产、高产创造条件。返矿具有多孔的结构，含低熔点化合物，有利于烧结过程液相的生成，提高烧结矿的强度，有利于烧结料粒度的组成，改善透气性，提高烧结矿质量。

冷挤压凸模为圆锥形芯棒，以圆锥凸模小端压入圆柱形钢管内(坯料外表面不受凹模作用)，则金属坯料在受到作用于内孔表面上的正压力时，金属坯料逐渐向外膨胀形成圆锥形管，同时在切向压力作用下，金属坯料沿轴向长度被缩短。根据金属变形的机理，先采用挤压凹模使圆柱无缝钢管坯料逐渐收口，再用圆锥凸模使圆柱无缝钢管逐渐扩口，形成整个圆锥形管件，冷挤压工艺方案见图2。冷挤压成形工艺过程分为四个阶段：阶段是将圆柱无缝钢管坯料压入凹模1；第二阶段将凹模2与凹模1组合起来，压力机将坯料逐渐压入凹模1与凹模2，此时坯料的一半长度受压而缩小成锥形；第三阶段将凸模1先压入坯料内孔与孔口平；第四阶段，将凸模2和凸模1组合起来，压力机继续将凸模1与凸模2向下压入坯料孔内，则坯料的上半部分被胀形成为锥管。
