对模铸工艺而言,浇铸高度的控制是一个重要环节。多年来国内各钢厂对浇高的控制一直采用目测的办法,很不准确,当浇高偏高时要浪费钢水,降低钢坯收得率;当浇高偏低时又容易产生缩孔废品,特别是采用绝热板及发热剂后,使目测浇高更为困难。当钢水接触绝热板后,板中的有机组分燃烧,产生很高的火焰;加发热剂后,由于体积膨胀,看不准钢液面,这些情况都给目测浇高带来困难。为了准确及时地控制浇铸高度,提高钢坯收得率,
For the molding process, casting height control is an important part. Over the years the domestic steel mills on the control of the pouring has been using a visual approach is very inaccurate, when the pouring high to waste molten steel, reducing the billet yield; when the pouring high and prone to cratering waste, In particular, the use of insulation panels and heat agent, the visual casting is more difficult. When the molten steel contacts the insulation board, the organic components in the board burn and produce a high flame. After adding the heating agent, it is difficult to visually confirm the pouring height due to the volume expansion and the inauthenticity of the molten steel surface. In order to accurately control the casting height in time and improve the billet yield,
