Abstract
According to the roller press roller sleeve with the full-face stud, the studs with different wear-resisting performances are alternately arranged on the roller surface, the difference of the wear-resisting performances of the studs is utilized to form the shape of the roller surface with the alternately concave protrusions in the use process of the roller sleeve, so that the capability of the roller surface of the roller sleeve to bite materials is improved, the extrusion angle of the roller press is increased, the alignment of two oppositely rotating roller sleeves of the roller press is the heterogeneous alignment of the studs, the raised position on one roller sleeve is aligned with the concave position on the other roller sleeve after the roller sleeve is worn in operation, so that the roller press has the functions of extruding force and breaking powder and shearing force, the powder breaking efficiency of the roller press is greatly improved, and the fine grinding of the roller press is realized.
Description
Technical Field
The invention relates to a column nail arrangement structure of a roller sleeve of a roller press with full-face column nails on the roller surface, relates to a roller sleeve wear-resistant layer design of the roller press for powder breaking, and belongs to the technical field of mechanical design and manufacturing.
Background
The wear resistance of the roller sleeve of the roller press of the inlaid hard alloy column nails is determined by the proportion of the sum of the sectional areas of the column nails to the area of the roller surface, namely the column nail surface density, the design of the existing inlaid column nail arrangement structure and the restriction of inlaid casting technology are restricted, the column nail surface density is restricted by the heat exchange balance between the column nail heat capacity and the overheat heat capacity of the molten steel flowing into the gaps between the column nails, the column nail surface density has a critical surface density, namely the maximum surface density, wherein the critical surface density refers to the maximum column nail surface density which can finish the complete filling of the gaps between the column nails under the auxiliary conditions of no external field force such as centrifugal force, vibration, external preheating and electromagnetic field, the critical density of the inlaid column nails cannot reach 50%, the wear resistance of the roller sleeve roller surface wear resistance layer is insufficient, the wear resistance of the inlaid column nail roller sleeve needs to be built up in the gaps between the column nails, and the wear resistance layer needs to be regularly built up and maintained; the roller sleeve of the roller press with the uniform column nails on the full surface of the roller surface has the advantages that the abrasion resistance of the column nails is consistent on the same circumferential direction, so that the roller surface is smooth, the extrusion angle of the roller press is reduced due to slipping when the roller surface is bitten into materials, and the powder breaking processing efficiency of the roller press is reduced.
According to the roller press roller sleeve with the column nails with full-face column nails, the column nails with different wear resistance are alternately arranged on the roller surface, and the difference of the wear resistance of the column nails is utilized to form the roller surface shape with the protruding concave parts alternately in the use process of the roller sleeve, so that the material biting capacity of the roller surface of the roller sleeve is improved, the extrusion angle of the roller press is increased, the powder breaking efficiency of the roller press is improved, and the column nails are arranged in a structure design which maximizes the wear resistance of the roller surface of the roller sleeve and improves the powder breaking processing efficiency of the roller press.
Disclosure of Invention
According to the roller press roller sleeve with the full-face studs on the roller surface, the studs with different wear resistance are alternately arranged on the roller surface, and the difference of the wear resistance of the studs is utilized to form the roller surface shape with the protruding concave alternately in the use process of the roller sleeve, so that the capability of biting materials into the roller surface of the roller sleeve is improved, the extrusion angle of the roller press is increased, and the crushing efficiency of the roller press is improved.
The invention relates to a concrete arrangement structure of column nails of a roller sleeve of a roller press with full-face column nails, which comprises three types of arrangement structures: arrangement structure 1: a row of hard alloy column nails and a row of steel bond hard alloy column nails are alternately arranged on the circumferential surface of the roller sleeve in the direction of a bus of the roller sleeve, and the roller sleeve is worn in the use process to form a bus stripe-shaped roller surface with alternately concave protrusions; arrangement structure 2: the hard alloy column nails and the steel bonded hard alloy column nails are alternately arranged in the busbar direction and the circumferential direction of the roller sleeve, and the roller sleeve is worn in the use process to form roller surfaces with alternately arranged convex and concave bosses and pits; arrangement structure 3: the roll sleeve circumference direction round carbide post nail and round steel knot carbide post nail are alternately arranged on the roll sleeve global, the roll sleeve wearing and tearing in the use form protruding concave alternate circumference stripe shape roll surface, two roll sleeve counterpoint modes of roll squeezer are round carbide post nail counterpoint round steel knot carbide post nail's heterogeneous post nail counterpoint mode, and this kind of post nail is arranged structure and the heterogeneous post nail counterpoint mode joint use between the roll sleeve, make the roll squeezer have the broken powder of extrusion force and have the broken powder function of shearing force, greatly improve the broken powder efficiency of roll squeezer and can realize the thin grinding of roll squeezer.
