Abstract
The present invention provides one kind of stainless steel ball and solves the problems of rusting, impact resistance and friction resistance of blasting metal surface while providing corresponding steel ball producing method and apparatus. The stainless steel ball has chemical components include, C, Si, Mg, Cr, Ni and B. The stainless steel ball product has bright and no-rust surface, no need of heat treatment and ball milling, long service life and high blasting and polishing efficiency, and may be used in sand blaster and shot blasting machine to treat various parts of non-ferrous metal, steel and other material in various fields.
Description
Technical field
The present invention relates to metal product and working method thereof and equipment, particularly a kind of stainless steel ball and working method and equipment.
Background technology
Metal finishing comprises rust cleaning, contents such as polishing.In fields such as non-ferrous metal, casting and stainless steel castings, it is not omissible operation that metallic surface is handled, and product and construction quality are played considerable effect.Shot-peening is one of metal finishing method commonly used.What the tradition blasting technology was used all is shot and the steel sand that plain carbon stool is made, and work-ing life is short, easily environment is polluted.Common shot surface is easy to oxidation and produces iron rust, and its shock-resistance and wear-resisting wiping are not strong.In spraying, can form a large amount of dust and distribute in air, destroy Air quality, also can cause serious harm operator's health, and its rust cleaning, polishing effect also needs further to improve.Thereby be the work that to carry out to the research of shot Material Selection and working method.Mechanical means is generally all adopted in the manufacturing of common shot---and be centrifugal shot blasting method production.Required production unit is many, and operation is long, production efficiency is low, requires the place big.As everyone knows, different materials, its production method is different with process system, and prepared product design all is different.
Summary of the invention
The objective of the invention is to disclose a kind of stainless steel ball, in order to solving in the shot-peening metal surface treatment process that shot easily gets rusty and shock-resistance, the not strong problem of wear-resisting wiping, and provide the working method and the equipment of corresponding this shot.
Owing to having anti-oxidant and corrosion proof special benefits, stainless steel is widely used in nearly all industrial sector.Particularly austenitic stainless steel is various in style, and performance and purposes are different, but they generally develop on 18-8 type basis and grow up.We also are placed on basic point on the 18-8 type, improve and reach product being generally expected that requirement by the interpolation metallic element.Our test also is from centrifugal ball blast method.Yet stainless steel ball is easy to generate tail and forms tadpole shape or teardrop shaped particle in centrifugal process of dishing out, do not reach the shape of product requirement.On the basis of test, we utilize the gas of certain pressure by nozzle the molten stainless steel cutting to be injected into tiny shot particle, drop to quick cooling in the water coolant then and glomeration.We have successfully grasped the production technology with the stainless shot of gas generation in the test of many wheels.
Its technical process such as accompanying drawing 2 show.
Its Chemical Composition and composition weight percent are:
Carbon 0.16～0.2%
Silicon 1.6～1.9%
Manganese 1.2～1.4%
Chromium 17～18%
Boron 0.6～1.2%
The chemical ingredients of stainless steel ball particularly boron plays an important role to formation of particulate circularity and performance; Rationally control stream pressure, flow and nozzle angular dimension can obtain the different stainless steel ball-type particle of thickness.
The equipment that the present invention uses is simple, easy to operate, and operation is lacked, can be boosted productivity effectively, and the bright as silver non-corrosive in the stainless steel ball of producing surface, need not thermal treatment or ball milling.Said shot long service life, the shot-peening time is short, and the efficient height is thrown in spray, and the surface to be machined light is rustless, and sandblast machine or shot-blasting machine all can use.Can produce the shot of various materials with this method, for a new road has been opened up in shot production.Can be used for non-ferrous alloy, foundry goods and stainless cast steel part, food machinery, medicine equipment, industry system jar and auto-parts, hardware products, industrial field and the occasions such as surface-conditioning deburring, rust cleaning, polishing and surface strengthening such as rod of rolling.
Description of drawings
Fig. 1 is the present device layout diagram.
Fig. 2 is a process flow sheet of the present invention.
Among the figure: 1-smelting furnace, 2-molten stainless steel, 3-ladle, 4-ladle water outlet, 5-air-flow, 6-surge drum, 7-shot, 8-water coolant, 9-metal drop, 10-nozzle, 11-pressed gas jet apparatus.
Embodiment
The melting in medium-frequency induction furnace of stainless steel material, after the furnace charge fusing, ferro-boron is joined in the molten steel, molten clear back slag making is also added silicon and carbon, adjusts temperature, begins to water steel after skimming, Open valve is jet simultaneously, take out shot after casting is finished in surge drum and clean, sabot is put in the baking oven then, treats the laggard row filter classification of the dried fully baking of moisture, and sampling detection physicals and chemical ingredients, press the different size class wrapping.
We find that by the contrast of each stove product the product particle circularity of interpolation carbon, silicon, boron is better in practice, and the product that does not add above-mentioned element becomes irregular sheet, and spherical particle is less.
Carbon can improve the intensity and the hardness of shot in stainless steel, but also reduces the corrosion stability and the plasticity of shot simultaneously, and addition can not be too high.
The silicon generally content in stainless steel is defined as less than 1%, and our add-on has surpassed conventional content, mainly is to want to increase molten steel flow, avoids the blocking package fault, moreover silicon can play the effect of protecting carbon, the oxidational losses of minimizing carbon.
Boron, boracic not nearly all in stainless steel, adding boron is in order to reduce the molten point of molten stainless steel, to gain in strength and necessary hardness and the wear resistance of product, increase the service life, reducing cost.
When the stainless steel metal liquid stream of fusing intersects impact by the ladle vertical landing and by the air-flow that laterally has certain angle, just producing atomizing makes molten metal be shattered into slick and sly particle, this solid solution drops in the air the circular solid particulate of flight after coagulation through a segment distance and falls in the water coolant, forms said stainless steel ball.
The equipment of said stainless steel ball comprises smelting furnace, ladle, baking oven etc., and it is characterized in that: processing units also comprises the pressed gas jet apparatus, and the nozzle of this gas injection apparatus is aimed at the ladle water outlet.Ladle water outlet below is provided with a shot container or a surge drum, is loaded with water coolant in container or the surge drum, and surge drum is funnel-form.
