Problems solved by technology

However, due to the large temperature change of the metallurgical furnace throughout the smelting process, the water temperature in the cooling water pipe in the cooling water system is also different.
Affected by the water temperature, the cooling water pipe expands with heat and contracts with cold, and cracks are likely to appear at the interface, resulting in leakage of the cooling water pipe

Embodiment Construction

[0009] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0010] The cooling water system with connecting hoses according to the present invention is welded by a plurality of horizontal metal cooling water pipes 1 and vertical metal cooling water pipes 2, the first welding joint of the horizontal metal cooling water pipes 1 or / and the vertical metal cooling water pipes 2 5. There is also a metal hose 3 near the second welding joint 6. The length of the metal hose 3 is 200-300 mm. The first welding joint 5 of the metal hose 3 and the first metal cooling water pipe 1, the second metal cooling water pipe The distance between the second welding joint 6 of 2 is 100-200mm. In order to facilitate the installation of the metal hose 3, the metal hose 3 is connected with the first metal cooling water pipe 1 and the second metal cooling water pipe 2 by flange 4.

Abstract

The invention provides a cooling water system with a connecting hose. The cooling water system is established by welding a plurality of metal cooling water pipes arranged transversely or / and longitudinally together; a metal hose is further arranged next to the weld connection of the metal cooling water pipes arranged transversely or / and longitudinally; the metal hose is connected with the metal cooling water pipe by use of flanges. The metal hose of the cooling water system is capable of counteracting the stress of the cooling water pipes caused by expansion with heat and contraction with cold, and therefore, pull cracks of the metal cooling water pipes are avoided and the service life of the metal cooling water pipes is increased.

Description

technical field [0001] The invention relates to a cooling water system, in particular to a cooling water system arranged outside a metallurgical furnace with connecting hoses. Background technique [0002] In the metallurgical industry, it is generally necessary to use cooling water to forcibly cool metallurgical furnace doors, slag discharge furnace doors and ring smoke hoods, etc., so it is inevitable to arrange a cooling water system outside the metallurgical furnace body. However, since the temperature of the metallurgical furnace varies greatly throughout the smelting process, the water temperature in the cooling water pipes in the cooling water system also varies. Affected by the water temperature, the cooling water pipe expands with heat and contracts with cold, and cracks are likely to appear at the interface, resulting in water leakage from the cooling water pipe. Contents of the invention [0003] The object of the present invention is to provide a cooling water...
