Problems solved by technology

This form of water-cooling system introduced in China has cooling pipes densely distributed around the rotating drum, and the water in the cooling pipes exchanges heat with the heat emitted by the rotating drum through the tube wall. Therefore, the cooling area of ​​this water-cooling system is small, resulting in low cooling efficiency. And the structure is complicated, the installation is complicated, and the price is expensive

Abstract

The invention relates to a water cooling system of an ironmaking furnace top distributing gear. The distributing gear comprises a rotary mechanism consisting of an upper rotary cylinder (4) and a lower rotary cylinder (6). At least one stage of platform (6-1) is arranged on the lower rotary cylinder (6). The water cooling system also comprises a water inlet pipe (2) and a water outlet pipe (10); the key of the water cooling system is that the water inlet pipe (2) penetrates through a distributing gear box (1) to be communicated with a rotary water tank (3) which is fixed at the rotary mechanism of the distributing gear. The water outlet pipe (10) is communicated with a fixed water tank (8) which is arranged at the outer side of the lower rotary cylinder (6) and is separated from the lower rotary cylinder (6). The lower part of the rotary water tank (3) is provided with a hole (3-1). The rotary water tank (3) is communicated with the fixed water tank (8) by the hole (3-1). The water cooling system has good cooling effect, convenient installation and maintenance and long service life and can be applied to various distributing gears of ironmaking furnace engineering.

Description

technical field [0001] The invention belongs to the technical field of metallurgical industry, and discloses a water cooling system for a waterfall-type ironmaking furnace top distributor. The system is used for water cooling of the top distributor of ironmaking furnace. Background technique [0002] The water cooling system of the iron-making furnace roof distributor is a necessary system for the iron-making furnace roof distributor, which is related to the use effect and service life of the distributor. At present, the water-cooling system of the distributor used in China is almost the water-cooling system attached to the imported foreign equipment. This form of water-cooling system introduced in China has cooling pipes densely distributed around the rotating drum, and the water in the cooling pipes exchanges heat with the heat emitted by the rotating drum through the tube wall. Therefore, the cooling area of ​​this water-cooling system is small, resulting in low cooling ...
