The manufacturer of Sealing Wire tells you that after chemical descaling and coating of the wire rod or intermediate wire, in order to remove hydrogen and moisture, it needs to be heated and dried at a low temperature. The drying temperature is generally %26lt; 300℃, and the temperature should not be too high to prevent the lubricating coating from failing. The manufacturer of Sealing Wire tells you that dehydrogenation is to eliminate the hydrogen that has penetrated into the steel base during the pickling process. The purpose is to eliminate hydrogen embrittlement and restore the plasticity of the wire rod. The purpose of removing moisture from the surface of the wire rod and making it dry is to prevent moisture from deteriorating the effectiveness of the lubricant.

The manufacturer of Sealing Wire tells you that there are 3 types of drying boxes with upper lids for commonly used drying facilities. The effective size is determined by the maximum diameter of the wire reel. The hot air of 150~250℃ is blown into the box during work. The drying speed of this kind of equipment is faster, the time is about 2~15min, and the drying is relatively uniform. The manufacturer of Sealing Wire tells you that the tunnel drying furnace relies on the combustion chamber under the furnace to provide the heat source, and the temperature of the drying chamber can reach about 280°C. The bottom of the furnace is covered with trolley tracks and arched cast iron radiating fins.
The dried wire rod or intermediate wire billet is hung on the trolley with the aid of a hanging bar, and is fed into the furnace by a hoist or manually. The manufacturer of Sealing Wire tells you that 10 to 12 carts can be loaded into each furnace. This equipment has a large capacity and a high output, but the labor intensity of the workers when entering and exiting the trolley is greater, and the drying temperature is uneven, and the temperature at the bottom of the trolley is relatively high. The manufacturer of Sealing Wire tells you that the bottom of the chain drying furnace is a combustion chamber, and the flame can return from the bottom to both sides of the furnace wall and then run out through the flue.
The furnace temperature is 200~400℃. When drying, the wire rod is placed on a moving chain, and the moving speed of the chain is about 12m/min. This is a more advanced furnace type with large capacity, high speed and high output, and it overcomes the labor intensity of tunnel furnace workers. The disadvantages of large and uneven drying temperature. The Sealing Wire manufacturer tells you that the coating process is to apply a firm layer on the surface of the wire rod or intermediate wire blank that has been removed from the oxide scale. It has a certain lubricating performance, especially when it is drawn, it can effectively absorb and carry the lubricant into the deformation zone. Of the substance.
