Abstract
The utility model discloses a modified hot dip galvanizing pot inner stabilization roller, including the roll body and at the closure plate of roll body both ends installation, closure plate center department is setting up the axle journal, and the roller diameter of roll body is 230mm, the axle journal diameter be 55mm, be the even interval of central symmetry on the face of closure plate and setting up the through-hole that three diameter is 20mm, closure plate thickness is 45mm, is being close to and is setting up an annular groove in the closure plate outer peripheral edge of the outer terminal surface of roll body. After modification, the stabilizing roller has the advantages that the self weight is reduced, the friction resistance arm is reduced, the running stabilizing roller and the surrounding zinc liquid have good cooperativity, the running of the stabilizing roller is improved, and the cost loss caused by large zinc layer fluctuation due to steel belt scratch and separation of the stabilizing roller caused by roller system rotation resistance or unsmooth running is reduced or avoided; the purposes of improving quality and reducing cost are achieved.
Description
Technical Field
The utility model relates to a modified hot-galvanize pot inner stabilizing roller.
Background
The stabilizing roller system is a main process device of a hot galvanizing unit, a stabilizing roller in a zinc pot is a passive steering roller, the running state of the stabilizing roller directly influences the smooth running of the hot galvanizing unit and the surface quality and the cost of strip steel, the stabilizing roller of the zinc pot is influenced by gravity W, buoyancy G and a roller arm bearing bush to act on the stabilizing roller of the zinc pot under the action of positive pressure N, static friction force f and inner surface friction torque M due to the fact that the self weight of the stabilizing roller is large, the designed structure and the designed size are unreasonable, the running stabilizing roller is poor in cooperativity with zinc liquid around the running stabilizing roller and large friction torque M, the stabilizing roller is easy to resist rotation or operate unsmoothly, the strip steel is scratched, and the zinc layer is greatly fluctuated along with the abrasion increase of a sinking roller shaft sleeve and the bearing bush during the middle.
Disclosure of Invention
An object of the utility model is to provide a stabilizing roll in modified hot-galvanize pot can improve quality, reduce cost, improve stabilizing roll operation conditions.
The utility model aims at realizing like this, a stable roller in modified hot-galvanize pot, including the roll body and at the closure plate of roll body both ends installation, closure plate center department is setting up axle journal, characterized by: the roll diameter of roll body is 230mm, the axle journal diameter be 55mm, be central symmetry on the face of closure plate and evenly set up three diameter for 20 mm's through-hole at the interval, closure plate thickness is 45mm, is being close to and is setting up an annular groove on the closure plate outer peripheral edge of the outer terminal surface of roll body.
The stress of the stabilizing roller in the zinc pot is known, and the maximum resistance of the operation of the stabilizing roller in the zinc pot comes from the friction force between the shaft sleeve and the roller arm bearing bush, so that the reasonable change of the structure of the shaft sleeve and the bearing bush of the stabilizing roller system plays a role in improving the operation state of the stabilizing roller system. Thereby taking measures: 1. the method comprises the following steps of (1) reducing the roller diameter of an original stabilizing roller from phi 250mm to phi 230mm, reducing the weight by about 12%, improving the roller operation, (2) reducing the shaft neck diameter phi 70mm of the stabilizing roller to phi 55mm, reducing the friction resistance arm of the roller operation, improving the roller operation, and (3) changing a 3-5 bolt hole which is radially and uniformly distributed on a blocking plate of the original stabilizing roller into a 3-20 through hole which is radially and uniformly distributed, so that the thickness of the operating stabilizing roller and the surrounding zinc liquid is increased, the operating resistance of the stabilizing roller is reduced, the operation of the stabilizing roller is improved, and the thickness of the blocking plate is from 35mm to 45 mm;
the production practice shows that: after modification, the stabilizing roller has the advantages that the self weight is reduced, the friction resistance arm is reduced, the running stabilizing roller and the surrounding zinc liquid have good cooperativity, the running of the stabilizing roller is improved, and the cost loss caused by large zinc layer fluctuation due to steel belt scratch and separation of the stabilizing roller caused by roller system rotation resistance or unsmooth running is reduced or avoided; the purposes of improving quality and reducing cost are achieved.
