Steelmaking electric furnace: introduction to the advantages of its tube water-cooled furnace cover

Views:2     Author:Site Editor     Publish Time: 2020-11-18      Origin:Site

The existing furnace covers of steel-making electric furnaces mostly adopt the structure of masonry refractory bricks. The disadvantages of the furnace covers of this structure are many brick cracks, poor overall performance, high energy consumption, short service life, and long maintenance.

 The purpose of the steel-making electric grate tube is to provide a tube-type water-cooled furnace cover, which has low energy consumption, long service life, and is convenient to replace and maintain.

The purpose of the steel-making electric grate tube is that the water-cooled block realized in this way is installed on the hanger of the furnace cover frame by bolts, and the small furnace cover is installed on the furnace cover frame through the positioning pins on the inner ring of the furnace cover frame to form the whole furnace cover. The water-cooling block is welded by closely arranged elbows, 180° elbows and 90° elbows.

The small furnace cover is welded by closely arranged elbows, 180° elbows and 90° elbows. The furnace cover frame is welded by the outer ring, the inlet pipe, the return water main pipe, the return pipe and the inner ring. The two ends of the water inlet pipe, the return water main pipe and the return water pipe are respectively welded to the outer ring and the inner ring. The water inlet pipe, the return water main pipe and the return pipe are welded with hangers, and the outer ring is welded with lifting lugs and the water inlet main flange. Locating pins are welded on the inner ring.

The new type of steel-making electric grate tube water-cooled furnace cover uses the water-cooled block and the circulating water in the small furnace cover water pipe to cool the furnace cover, which has low energy consumption. Under normal use, its life can reach more than 1500 furnaces. It is a refractory brick structure The life of the furnace cover is more than 200 times. Because the furnace cover adopts a split structure, it is convenient to replace and maintain, and is easy to transport.
