New type tubular water cooling furnace cover

The water cooling structure in the furnace cover is composed of a number of tightly arranged seamless pipes.

Each steel pipe is round. The water-cooled furnace cover of this structure is not easy to leak and easy to maintain.

The water cooled furnace cover of electric arc furnace adopts tubular frame water cooled furnace cover, and the water cooled cover is designed in two halves for easy replacement and transportation.

The water-cooled furnace cover comprises a tubular frame, a water cooling fast on the left half cover, a water cooling fast on the right half cover, a lime charging device, and a water-cooling support ring on the central small furnace cover. The tubular frame is made of seamless steel pipes, which are not only used as the strength requirements of the structural parts, but also as the main inlet and return water pipes. Connect all cooling water circuits through the main inlet and return pipes. The left and right half water cooling blocks are connected to the frame by bolts, and the water cooling fast forward and return water are connected to the main inlet and return water pipes by branch steel pipes to cool the two half water cooling blocks.

The lime charging device is installed on the furnace water cooling cover. The device is composed of a receiving hopper, a chute, etc. The lower part of the chute is designed as a water cooling structure. When no lime is added, the sluice valve is closed to prevent the flue gas from overflowing from the lime charging device.

The water-cooled support ring of the central small furnace cover is made into an inverted cone structure, and water cooling is also adopted. The water inlet and return pipes are connected to the main water inlet and return pipes.
