Abstract

The invention provides a safe and durable towing hook for a blast furnace. The safe and durable towing hook comprises a main body, two hook heads, a front baffle plate, a sliding weight and a handle, wherein the main body is rod-shaped; the hook heads are arranged on one side of the back end of the main body; the front baffle plate is arranged on the main body and is close to the front end of the main body; the sliding weight comprises a sliding weight body and an operating handle which is arranged on the sliding weight body, and the sliding weight main body can be sleeved on the main body in a sliding mode and is positioned between the front baffle plate and the hook heads; the handle is arranged at the front end of the main body; and the two hook heads are respectively arranged on two opposite sides of the back end of the main body. The safe and durable towing hook has a long service life, the hook heads are bilateral hook heads, and during operations of replacing medium-size and small-size sleeves, particularly during the operations of replacing the medium-size sleeves, the hook heads are uniformly heated and stressed, so that the service life of the towing hook is long.

Description

technical field [0001] The invention relates to an auxiliary tool for blast furnace ironmaking, in particular to a tow hook for replacing a tuyere of a blast furnace, belonging to the technical field of metallurgy. Background technique [0002] In blast furnace ironmaking production, blast furnace tuyere devices include large, medium and small sets. Among them, the large sleeve is connected to the furnace skin and covers the middle sleeve, the middle sleeve covers the small sleeve, and the small sleeve sends hot air into the blast furnace. The temperature of the hot air is generally as high as 1100 degrees. The middle sleeve is generally made of cast iron, and the small sleeve is generally made of copper. All are water cooled. Due to the extremely harsh working environment of the blast furnace tuyeres, the small and medium sleeves are often burned out, forcing the blast furnace to shut down and need to be replaced frequently. Especially the small tuyere cover, which direct...
