The galvanizing production line is an integral assembly line, and the strip is annealed, reduced, heat-insulated and zinc-potted to produce qualified products. The hearth roll is the bridge for strip steel entering and leaving the furnace, and it plays an irreplaceable role in the production of M hours per day. However, the energy consumption of the hearth roll is also quite large. The reason is that the middle of the hearth roll is watered, which cools the hearth roll and ensures that the hearth roll does not bend. In this way, 10% of the heat is removed by water cooling, and 24/7 production will lose a considerable amount of heat.

 

After research, the shortcomings of the existing technology are overcome, and a hearth roller of a galvanizing line with scientific design and energy consumption reduction is provided.

 

Advantages and positive effects of retrofitted hearth rolls for galvanizing lines:

  1. The bottom roller of this furnace is covered with stainless steel plate at the place with the largest diameter, so that water is not allowed to flow inside, and only water enters and exits on the bearing seats on both sides. This reduces energy consumption and ensures smooth production.
  2. The bottom roller of the furnace installs the water inlet and outlet on a rotary joint to realize the inlet and outlet water in a through hole, allowing the water to enter from the water inlet pipe, and the internal high temperature generates pressure, so that the water is discharged from the water outlet pipe , the overall structure is simple, the design is scientific and reasonable.
