在现有条件下,正确选择工艺系数并使之合理配合,即可获得较高的铁水温度和熔化速度,从而降低焦炭消耗量,降低废品率,提高铸件质量,在3.0吨/时多排小风口冲天炉上试验已获如下效果: 1、平均铁水温度稳定在1450℃～1500℃; 2、焦耗下降10％～20％; 3、熔速提高10％～15％。 Under the existing conditions, the correct selection of process factors and to make it a reasonable match, you can get a higher temperature of molten iron and melting speed, thereby reducing coke consumption, reduce scrap rate, improve casting quality, 3.0 tons / Oven cupola test has been the following results: 1, the average hot metal temperature stabilized at 1450 ℃ ~ 1500 ℃; 2, coke consumption decreased by 10% to 20%; 3, the melting rate increased by 10% to 15%.
