对大钟与漏斗接触面损坏的原因本人有如下分析: 1.由于高炉操作情况不应,引起炉喉煤气流分布不均,炉顶温度过高,使大钟或漏斗产生局部变形,密合同隙显著变大。由于大钟上下的压力差很大,磨损力很强的高压煤气流,通过接触面的不严密处外流,随即把大钟与漏斗的接触面逐渐吹损。 2.设备制造质量不高,在运输、安装过程中变形,安装质量不高等也可造成密合间隙过大。如大钟和漏斗的接触间隙在制造厂时很好,但安装在高炉上后同隙值变大了
The bell and the funnel contact surface damage I have the following analysis: 1 due to blast furnace operation should not be caused by the furnace gas flow distribution, roof temperature is too high, the bell or funnel local deformation, close contact with the The gap becomes significantly larger. Due to the great pressure difference between the upper and lower bell, high pressure gas flow with strong abrasion force flows out through the non-close contact surface, and then gradually blows the contact surface between the bell and the funnel. 2. Equipment manufacturing quality is not high, in the transport, installation process of deformation, installation quality is not high, also can cause close gap. Such as the bell and the funnel contact gap at the factory when the good, but installed in the blast after the gap value becomes larger
