I don't know whether the oxygen used for steelmaking comes from liquid or compressed gas. If liquid oxygen is used, the boiling point of liquid oxygen is-183 degrees Celsius, and the temperature of vaporized oxygen is of course very low. When the dosage is large and the flow rate is fast, the temperature of the rubber tube is taken away by low-temperature oxygen before it can absorb heat from the air, which will reduce the temperature of the rubber tube. When the dew point temperature is reached, the moisture in the air will first condense into water droplets on the surface of the rubber tube, and then form frost. At this point, the temperature of the rubber tube must be below zero.
