Continuous Annealing Line (For Strip Steel)

The continuous annealing line for strip steel processing combines several separate operations, including cleaning, bell annealing, cooling, flattening, and finishing, into a single process. This strip processing line utilizes a floor-standing continuous annealing furnace to replace the previous bell annealing furnace that can only operate intermittently. This ensures higher productivity. Strip steel that has been worked on this continuous annealing line is uniform in softness and ductility. Ductility is important in shaping a more refined workpiece.

One technical challenge facing every continuous annealing line manufacture is that annealing often results in oxidization of metal surface, resulting in scale. To address this issue, a sealing device is installed at the entry to the furnace chamber. This sealing device has already been patented, namely the sealing device for silicon steel and ordinary carbon steel continuous furnace door. Thanks to the seal, the sealing performance of the furnace door is greatly enhanced. Durable and long-lasting, the seal does not need to be replaced for many years. This saves on production and operating cost.
