Background
In the full-automatic tunnel acid pickling phosphating line equipment for the wire rod, after the wire rod is neutralized or saponified, the wire rod needs to enter a drying box to remove the moisture on the surface of the wire rod, so as to prevent rusting.
At present, the operation mode of a drying furnace commonly used in the industry is as follows: the combustor produces hot-blast, gets into the stoving case through the blast pipe by circulating fan, and the wire rod gets into the stoving case, self-closing upper cover plate, and hot-blast back through the wire rod is sucked the combustion chamber through circulating fan through the circulating air pipe again, mixes with the hot-blast of the production of combustor again, is sent into through the blast pipe by circulating fan again, and the circulation is reciprocal like this.
In the actual operation process, the drying temperature in the drying furnace reaches 150 ℃, the temperature is high, the burner works in a big fire state for a long time, but the effect of the drying furnace is good at the beginning of operation, and after several times of drying, the drying effect is gradually reduced. Even if the drying time exceeds 6 minutes, although the moisture on the outer surface of the wire rod is removed, the moisture in the inner gap and the bottom of the wire rod still exists; the reason is that after drying, moisture on the surface of the wire rod is evaporated into a large amount of water vapor at high temperature, hot air in the oven contains a large amount of moisture, and because the upper cover plate of the oven is in a closed state in the drying process, most of moisture in the air can not go everywhere, only a small amount of moisture is dissipated and removed through the gap between the upper cover plate and the oven, and after recirculation, hot air re-entering the oven still carries a large amount of moisture, so that high-temperature humid hot air always exists in the oven, and the expected drying degree is difficult to achieve.
