Abstract

The invention relates to a water-cooled plug with automatic bypass cooling. The plug comprises a plug casing and a connector arranged in the cavity of the plug casing and the lower part is rotatably connected with the corresponding position of the lower part of the plug casing through a connecting assembly, and a connector arranged inside the plug casing Inverted cone on the top, the core of the connector is hollow and the bottom is connected with a water inlet pipe, and the inner side of the connection between the connector and the plug shell is provided with water outlet holes evenly distributed around the axis, and the plug shell is connected with the connector. The outer side of the connector is provided with shrinkage cooling holes evenly distributed around the axis, the inlet end of the shrinkage cooling hole is communicated with the connecting assembly, and the outer side of the bottom of the connector is provided with an adsorption friction plate in contact with the bottom of the plug shell. The invention can avoid the accumulation of steam bubbles in the inner cavity of the plug shell, and at the same time can effectively solve the problem that the plug shell is easy to be stuck when retreating, and realizes automatic branch cooling, simple structure and high equipment transformation economy.

Description

technical field [0001] The invention relates to the technical field of water-cooled plugs, in particular to a water-cooled plug with automatic branch cooling. Background technique [0002] Plates, pipes, and profiles are important components in the field of iron and steel metallurgy. In the field of steel pipe production at this stage, the plug is an important production tool for the production of seamless steel pipes. The required cavities are drilled in the billet heated to a high temperature to produce seamless steel pipes. Currently commonly used plugs have a high damage rate during production, which is usually caused by the untimely cooling during drilling and the temperature of the outer surface of the plug exceeding the maximum working temperature for a long time, resulting in adhesion with the inner wall of the seamless pipe or deformation of the outer surface of the plug. As a result, it is also more common for the head to be stuck in the tube and unable to withdra...
