The invention discloses a method for connecting a water inlet pipe and a water outlet pipe of a blast furnace cooling wall. The method adopts a connecting and adjusting method of a movable joint, double nipples, an elbow and a connecting pipe; and what is more important, the connecting method can eliminate the deformation stress in all directions, which is generated by the water inlet pipe and the water outlet pipe of the cooling wall and an external connecting pipeline, by connecting the movable joint, the elbow, the double nipples and the connecting pipe into a U-shaped structure which is perpendicular to the ground through adjusting the elbow and the double nipples, thereby reducing the deformation and cracking of the pipeline and effectively protecting the normal circulation cooling of the cooling water of the cooling wall. The invention has favorable popularization use value.
Description
Connection method of inlet and outlet water pipes of blast furnace stave technical field The invention relates to a cooling wall of a blast furnace, in particular to a method for connecting water inlet and outlet pipes of the cooling wall of an ironmaking blast furnace. Background technique The furnace body of the ironmaking blast furnace is composed of an outer shell, continuous cooling staves, and refractory bricks. The stave is used to solve the heat dissipation problem of the blast furnace. The cooling effect of the stave has a great influence on the normal operation of the blast furnace. The wall is generally water-cooled, so the normal and continuous water supply of the cooling water system in the cooling wall is necessary. But in practice, with the change of the working environment and the normal production of the blast furnace, sometimes the furnace body will expand or the cooling wall will be deformed, which will easily lead to distortion, deformation, or even cra...
