Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel wire processing, in particular to a lead temperature constant device for a steel wire continuous heat treatment line and a constant wind device for a drying room. Background Art
[0002] Before austenitizing the tire bead wire, the wire needs to be degreased to obtain a uniform surface color so that it can receive uniform radiation during the austenitizing heat treatment. In addition, the soap powder remaining on the surface of the wire after drawing can be removed to prevent too much soap powder on the surface of the wire from heating up too quickly during austenitizing. The degreasing tank is generally heated by steam. When the wire enters the lead quenching tank after austenitizing, the heat on the wire surface will accumulate, which will cause an overheating zone to form at the entrance of the lead quenching tank, causing proeutectoid ferrite to form inside the wire, and the formed lamellar pearlite will also be coarser, thereby reducing the mechanical properties of the tire bead wire. Therefore, a cooling circulating water pipe is generally used to cool down the overheating zone. The subsequent phosphating process also requires steam heating of the phosphating liquid to ensure a good phosphating film to meet the subsequent drawing.
[0003] There are two processes in the continuous heat treatment production line for steel wire, the lead bath for the steel wire and the drying after washing. The temperature control meter of the lead cylinder of the lead bath for the steel wire directly controls the contactor to start the blower, and then discharges the hot air to the outside; the heat in the drying room is heated by electric heating pipes. These two methods have high energy consumption. For this reason, we propose a lead temperature constant device for continuous heat treatment of steel wire and a constant wind device for the drying room to solve the above problems.
