Water cooling cantilever roller way for steel billet heating furnace

Abstract

The invention discloses a water cooling cantilever roller way for a steel billet heating furnace. The roller way comprises a roller shaft and a roller. The roller shaft comprises a water inlet pipe, a hollow shaft, an inner pipe and a water distributing block. The roller comprises a roller body, an inner ring, a fixing plate and an end cover. The roller body is in the shape of a hollow barrel; one end of the roller body is closed through the end cover; the other end of the roller body is closed through the fixing plate; the roller body is internally provided with the inner ring in the radial direction which divides the inner cavity of the roller body into a front cavity and a rear cavity; and the inner ring is evenly provided with a plurality of communicating holes used for communicating the front cavity with the rear cavity. The hollow shaft penetrates the fixing plate and the inner ring, and the hollow shaft, the fixing plate and the inner ring are fixed. One end of the inner pipe is fixed to the end cover, and the other end of the inner pipe is inserted in the hollow shaft. The water inlet pipe penetrates the inner pipe, and the water distributing block is arranged between the inner pipe and the water inlet pipe. A plurality of water inflow holes are formed in the portion, close to the end cover, of the inner pipe and used for communicating the inner pipe with the front cavity and communicating the water inlet pipe so that cooling water in the water inlet pipe can enter the front cavity. The portion, in the rear cavity, of the hollow shaft is evenly provided with a plurality of water outflow holes used for communicating the rear cavity and a cavity in the hollow shaft.

Description

technical field [0001] The invention belongs to the technical field of cantilever roller table repair, in particular, the invention relates to a water-cooled cantilever roller table used in a billet heating furnace. Background technique [0002] In the steel rolling heating furnace, especially for the heating of small-section and large-length billets in the bar production line, the loading and unloading method generally adopts the side-in and side-out method. At this time, the cantilever roller table must be used to complete the billet in the furnace. delivery. Such as figure 1 As shown, the cantilever roller table consists of roller shaft 1, roller 2, flat key 1 3, flat key 2 4, stopper 5, water inlet pipe 6, bearing seat 1 7, bearing seat 2 8, motor reducer 9, flange 10 , rotary joint 11, connecting shaft 12, hollow shaft 13, inner tube 14, water diversion block 15 and end plate 16. At the discharge end with a higher temperature, the material of the roller 2 generally a...
