分析认为,济钢大板坯连铸机出现粘结漏钢的原因是保护渣的性能不良,其中液渣层厚度、渣耗量及玻璃相比例偏低,以及结晶器液面波动,拉速提升过快等。
Analysis consider that the reason of breakout by sticking is bad capability of the powder, such as lower depth of liquid powder, less consumption and low proportion of glass phase in the powder.
盐析后,结晶盐填充了岩心中的小孔隙,小孔喉在岩心中的比例明显减少,渗流通道减小,有的甚至完全被堵塞。
After salting out, the fine pores are filled with salt crystals and the proportion reduces significantly, which cause the flow channels downsized and some are even completely blocked.
冷结晶温度和熔融温度与共混比例、共混时间、温度等因素密切有关。
The blending composition, temperature and time have a dramatic effect on the cold crystallization temperature (Tc) increases and the melting Tmperature (t m).
