Abstract
A kind of casted alloy crucible that relates to low melting point non-ferrous metals such as the molten aluminium of casting industry, lead, tin (is called for short: casted alloy crucible for aluminium melting), present graphite crucible, chromium manganese nitrogen or the chromium 9 silicon 2 cast steel crucibles that use, these dried crucible lifes are low, stream time was generally 500 hours, price is expensive, high chromium nickel stainless steel crucible reaches 20,000 yuan/ton, wherein electric furnace melts existing chromium manganese nitrogen or the chromium 9 silicon 2 cast steel crucible life instabilities of aluminium, hang down and reach 100 hours, up to 500 hours, 7200～9400 yuan/ton of prices.Principal character of the present invention is that crucible is divided into four-layer structure by inner surface to outer surface, and at the bottom of the crucible, crucible body, crucible be along cast solid, compares with chromium manganese nitrogen or chromium 9 silicon 2 alloy cast steel crucibles, the life-span is improved 2-14 times, and price reduces by 1/5-1/4.
Description
A kind of casted alloy crucible that relates to low melting point non-ferrous metals such as the molten aluminium of casting industry, lead, tin (is called for short: casted alloy crucible for aluminium melting).
The crucible of low spot non-ferrous metals such as present molten aluminium, lead, tin is graphite crucible, chromium manganese nitrogen or chromium 9 silicon 2 alloy cast steel crucibles, high chromium nickel stainless steel crucible normally, also has extremely low high silicon magnesium iron crucible of life-span.These crucible lifes are low, and stream time is generally 500h, and price is expensive, high chromium nickel stainless steel crucible reaches 20,000 yuan/t, and wherein molten existing chromium manganese nitrogen or the chromium 9 silicon 2 cast steel crucible life instabilities of aluminium industry of electric furnace are hanged down and reached 100h, up to 500h, 7200～9400 yuan/t of price.
The purpose of this invention is to provide a kind of casted alloy crucible for aluminium melting, its crucible edge, crucible body and crucible uphill casting are integral, inner surface is made by the different chemical prescription to outer surface has four-layer structure, service life 1000-7000h, 1800 yuan/t of cost compares with existing chromium manganese nitrogen or chromium 9 silicon 2 alloy cast steel crucibles, and the life-span is improved 2-14 doubly, price reduces 1/5-1/4, solves inside and outside etching problem.
Invention is achieved in that
On the basis of cast iron, add ferrochrome, strict control Mn, Si, C content, and adopt unique model, cast and annealing process, form the spoken parts in traditional operas of certain mechanical performance, thereby make the crucible body.Then inner surface of crucible and outer surface are handled, formed four-layer structure at last.Its inner surface is dope layer (1), and the centre is crucible body layer (2), and outer surface is aluminized coating (3) and aluminum layer (4), crucible wall thickness 20-50mm, and physical dimension is divided into standard type and the user goes out the non-standard of pattern processing.
The concrete structure of invention is provided by following embodiment and accompanying drawing thereof.
Fig. 1 casted alloy crucible for aluminium melting structural representation.
Describe the details and the working condition of foundation concrete device proposed by the invention in detail below in conjunction with accompanying drawing.
Casted alloy crucible for aluminium melting be (5), crucible body (6) at the bottom of the crucible, crucible along (7) cast solid, by inner surface dope layer (1), intermediate body member layer (2) and outer surface aluminized coating (3) and aluminum layer (4) constitute, manufacturing process is filled a prescription as follows:
Make the chemical analysis and the prescription of usefulness:
C is 3.0～3.4%, Si is 0.7～2.5%, Mn is 0.6～0.9%, P＜0.3%, S＜0.3%.Cr is 3.0～5.0%, and all the other are Fe(iron), all % counts by weight, be cast as crucible body layer (2), hot-dip aluminizing or thermal spraying aluminum on body layer (2) outer surface form aluminum layer (4) and aluminized coating (3), at body layer (2) inner surface swabbing, formulation for coating material: 90% talcum powder, 5% zinc oxide, 4% waterglass, 1% machine oil, the % meter adds water furnishing pasty state by weight, brush and form inner surface dope layer (1), promptly cast casted alloy crucible for aluminium melting.
The intermediate alloy cast iron layer is crucible body layer (2), and its special composition has the ability of stronger anti-aluminium corrosion.Inner surface dope layer (1) further strengthens the corrosive power of anti-aluminium, and this layer is in use to be implemented by the operator.Outer surface is aluminized or thermal spraying aluminium lamination (4), (3), guarantees the long-term oxidation resistant ability below 1000 ℃ or the ability of anti-sulfuration, further improves pot life, and this layer is by aluminizing or hot-spraying technique enforcement.During crucible work, inner surface is corroded by strong aluminium, and outer surface suffers high-temperature oxydation or high temperature vulcanized.Inside and outside corrosion makes the sidewall of crucible attenuation, so that damages.The present invention has solved the problem of inside and outside corrosion effectively, because crucible has the higher life-span.This crucible is divided into HT series and HTL series, and what be made of inner surface dope layer (1) and intermediate body member layer (2) is the serial crucible of HT, is HTL series at the crucible that the serial crucible outer surface of HT is aluminized or thermal spraying aluminum is made, and HTL series has the higher life-span.
Embodiment 1: test data
HT series crucible, φ 450 * h800 * δ in August, 40,1988-August nineteen ninety, service life＞7000h continuously.
Embodiment 2: test data
HT series crucible, φ 450 * h1500 * δ in August, 40,1986-so far, continuously service life 1200h.
Embodiment 3: test data
HT series crucible, φ 500 * h690 * δ 30, June nineteen ninety so far, continuously service life 1000h.
Embodiment 4: test data
HTL series crucible, φ 400 * h300 * δ 20, October nineteen ninety-so far, be 1000h service life continuously, do not have any corrosion.
Through actual verification, casted alloy crucible for aluminium melting (HT series and HTL series) is that present home costs is minimum, the crucible of longest-lived, estimates domestic consumption 4-10 ten thousand t, both fills the domestic gaps, and is again that society creates big benefit.
