Description
Technical field
The present invention relates to the plant equipment and the preparation technology in general fragmentation, grinding, conveying, flotation, pulverizing field, particularly foreplate and the preparation technology thereof under the impact wear operating mode.
Background technology
Foreplate has the blank of importing and escorts effect in processes such as rolled steel, its working face bears impact, friction and the extruding of hot steel billet simultaneously, and the Quench of cooling water, and working condition is more abominable, and the working position wearing and tearing are very serious.So it is foreplate is changed more frequent, also bigger to producing influence.This shows,, need the comprehensive mechanical property under the normal temperature, also need the mechanical property under the high temperature simultaneously for foreplate.Therefore, select scientific and rational material and manufacturing process for use, produce higher foreplate in service life, important meaning is all arranged enhancing productivity, reducing production costs.
Past, the foreplate that domestic many steel rolling mills use white cast-iron, spheroidal graphite cast-iron, low-alloy steel to produce more, the foreplate of these materials weares and teares easily, and service life is shorter, and maintenance is changed frequent, directly influences production efficiency and production cost.In recent years, many producers adopt Gao Ge, nickel alloy to produce foreplate and obtained than obvious effects, also the overall economic efficiency of Ti Gaoing.But, Gao Ge, nickel alloy prices of raw and semifnished materials costliness.As every heavy 16kg of finishing mill foreplate, and the more serious less part of having only of wearing and tearing, waste of material is comparatively serious.Therefore have only by combination process the material of different qualities is combined, and the comparatively serious position of local synergic wear, make the composite foreplate and take into account the each side mechanical mechanics property, could satisfy the needs of various operating modes.China utility model patent CN2495390Y discloses a kind of composite alloy material guide and guard board, it be with low-alloy steel such as 40Cr as body, the working face part is made with unit or binary and multicomponent alloy layer.CN101195156A discloses a kind of preparation method of casting and seeping foreplate of rolling mill, and this foreplate is to reach wear-resisting purpose at the compound alloy powder with the ball mill refinement of working face.China utility model patent CN200998736Y discloses a kind of foreplate that working face is designed to waveform.CN1706635A has invented compound foreplate of a kind of bimetallic and preparation method thereof.CN101412095A discloses a kind of preparation method of composite wear-resistant foreplate, and what it adopted is that the alloyed powder plug is prefabricated in the die cavity of foreplate casting mold, melts bar by the heat effect of substrate metal then, thereby obtains having the foreplate of complex abrasion-proof layer.What above foreplate and preparation method thereof had can't satisfy actual use needs, the complicated process of preparation that has, and production cost is high, can't carry out industrialized large-scale production.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide a kind of and can satisfy high-performance foreplate and the preparation technology thereof who uses under the complex working conditions such as various wearing and tearing, impact.Adopt polyvinyl alcohol as binding agent, alloy powder as penetration-assisting agent, with simple manufacturing process extremely, hard ceramic particles be compounded in foreplate frayed with the working face that impacts on form wear-resistant hard mutually, make the foreplate working face both have the intensity and the toughness of substrate metal, the high rigidity of ceramic hard phase is arranged again and do wearability, power, high frequency cyclic loading and strong wear simultaneously can withstand shocks, has very high cost performance, also be fit to large-scale industrialization production, improve 5 ~ 8 times than common foreplate the service life of foreplate.
Composite machine of the present invention is defended plate, a base material (1) that adopts any one making in potassium steel, steel alloy, high chrome and the high-carbon steel is arranged, it is characterized in that, partly be compounded with the hard ceramic particles layer (2) of one deck by hard ceramic particles and metal powder metallurgy combination at the working face of said foreplate; Said hard ceramic particles is 1 ~ 4 kind in carborundum, tungsten carbide, silicon nitride, the titanium nitride, and when hard ceramic particles was made up of two or more ceramic particles, the ratio between its constituent element was arbitrarily; Said metal dust is any one in nickel powder, cobalt powder, molybdenum-iron powder, the ferrotungsten powder, and its adding proportion is 5 ~ 25% of a hard ceramic particles weight.
The grain diameter of said hard ceramic particles layer (2) is-40 ~+80 orders, and the thickness of hard ceramic particles layer (2) is 2 ~ 6mm.
The preparation technology of composite foreplate is characterized in that, preparation section is as follows:
A,Binding agent polyvinyl alcohol, metal dust and hard ceramic particles are mixed, after stirring, be routed in the foreplate bubbles model (3) by designing requirement, its THICKNESS CONTROL is at 2 ~ 6mm; The adding proportion of metal dust is 5 ~ 25% of a hard ceramic particles weight, and the adding proportion of binding agent polyvinyl alcohol is 2 ~ 5% of a hard ceramic particles weight;
B, smelt the fusing substrate metal, come out of the stove after reaching base materials employed metal tapping temperature, pour in the model (3), till filling with intermediate frequency furnace; Under the heat effect of substrate metal, the binding agent gasification is discharged, and ceramic particle is full of substrate metal in the gap, and the dissolving and the diffusion of trace take place between ceramic particle and substrate metal, make to form the excellent metallurgical combination between the two, constituted the composite foreplate of wearability and obdurability matched well;
C, treat that the substrate metal liquid cooling is but solidified after, take out casting cleaning, promptly make the base steel composite material foreplate that working surface is strengthened by hard particles.
Compare with prior art, the present invention has following beneficial effect:
1, because ceramic particles such as carborundum, tungsten carbide, silicon nitride, titanium nitride has very high hardness, generally be 8 ~ 10 times of conventional metals high-abrasive material hardness, therefore after being compound to the foreplate surface, can become good wear-resistant hard phase, the cutting and the cutter of foreplate are cut when the foreplate apparent motion to resist material, improve the service life of foreplate, improve 5 ~ 8 times than common foreplate.
2, the binding agent polyvinyl alcohol is cast moment at substrate metal, can prevent that hard ceramic particles is defeated and dispersed, and after casting is finished, polyvinyl alcohol gasifies under the high temperature action of substrate metal and discharges from casting mold, can not stay genetic defects such as slag inclusion, hard ceramic particles is full of substrate metal in the gap, ceramic particle is realized the good supporting effect, because ceramic grain surface generation oligodynamical and atom diffusion under the high temperature, therefore have very strong adhesion with substrate metal, avoided foreplate in use under high-frequency percussion load ceramic particle come off.
3, the hard ceramic particles composite thickness can carry out freely designing in 2 ~ 6mm scope according to the actual working conditions needs, realizes the control to the foreplate production cost, obtains very high cost performance.
4, compound preparation technology's controllability of the present invention is strong, the yield rate height, and the quality of production is stable, is convenient to large-scale industrialization production.
