A kind of method that the present invention proposes high nickel matte slow cooling mold and casting, the high nickel matte of slow cooling, mold is made of body and insulation cover, body is suitable for reading greatly, bottom is small, inner surface is inclined-plane, there are four rounded corners for side wall, symmetrical clamp port is respectively equipped on two opposite side, for body by steel fibre pouring material monoblock cast, it is suitable for reading that insulation cover is covered on body.Ground inside workshop is digged pit, and mold is put into hole, on mold along with it is near coal-mine concordant, mold and cheat between gap tamped with sandy soil.Uniformly preheating before casting, with anti-cracking.Clamp port is closed with yellow mud, and high nickel matte covers insulation cover after pouring into mold immediately.Advantage: the generation of mould craze and transfiguration phenomenon is reduced.Both it can guarantee the service life of nickelic sulfonium slow cooling mold, while having guaranteed the slow cooling effect of high nickel matte.
Description
Technical field
The invention belongs to nickel fibers fields, are related to the Slow cooling of the high nickel matte of high-temperature molten-state.
Background technique
The high nickel matte of high-temperature molten-state is mainly the compound of nickel, copper and sulphur, also has a small amount of iron, cobalt, oxygen, your micro gold
Category and other impurity.Slow cooling is carried out, keeps various components point different into the separable crystal grain with different chemical phases, slow cooling
Journey is completed in a fixed mold.Original mould is formed using iron casting, and inside is reinforced using lacing wire, and geometric volume is
4.58m3, the high nickel matte weight that can cast is 25t.The problem of former high nickel matte mould will appear following several respects in use:
1, high nickel matte mould service life is low.It is restricted by material, mould, which is washed away in casting process by high nickel matte, will lead to mould
Sub- bottom or side is impaired, while cast iron mould is acted on by high-temperature fusant thermal stress, is caused mould body to crack, can not be continued
It uses.Currently, the service life of cast iron mould is casting high nickel matte 120 times or so, it is lower to pour mold service life, and flash
After smelting system yield task gradually increases, service life is low to cause high nickel matte mould replacement more frequent, and consumption costs is larger.
2, post operation difficulty increases after mould deformation.Mould after craze and transfiguration can be flowed in casting process high temperature melt
Entering crack, high sulfonium block sticks to one with mould after slow cooling molding, in addition because mould deformation causes high sulfonium block-shaped irregular, it is nickelic
Sulfonium acts process difficulty, increases post work labor intensity.
3, high nickel matte physical appearance quality is influenced.Due to mould badly broken, in order to guarantee normally the pouring of high nickel matte, delay
It is cold, act operation, just largely paste mends yellow mud at damaged mould seam, and it is larger that the high nickel matte after leading to slow cooling adheres to loess amount,
High nickel matte external form is irregular, seriously affects the physical appearance quality and downstream process index of high nickel matte.
Summary of the invention
The purpose of the present invention is aiming at the shortcomings of the prior art, provide one kind both to have can guarantee nickelic sulfonium slow cooling effect
Fruit, promotes the cost performance of high nickel matte mold, and reduces the mold of the labor intensity of worker.
The purpose of the present invention is what is be achieved through the following technical solutions: a kind of high nickel matte slow cooling mold, the mold is by body
Formed with insulation cover, body it is suitable for reading it is big, bottom is small, inner surface is inclined-plane, and side wall is set on two opposite side respectively there are four rounded corner
There is symmetrical clamp port, for body by steel fibre pouring material monoblock cast, it is suitable for reading that insulation cover is covered on body.
Convex block is respectively equipped on another two opposite side, convex block is equipped with annular groove.
Insulation cover is equipped with lower along side, and heat preservation cover material is heat-resisting cast iron, and lifting lug is arranged at top.
A method of it is cast using above-mentioned mold, the high nickel matte of slow cooling, the ground inside workshop is digged pit, and is cheated and is
Pyramid, bottom surface sand layer, and angle scrapes out arc transition, and mold is put into hole, on mold along with it is near coal-mine concordant, mold and
Gap between hole is tamped with sandy soil, and uniformly preheating, clamp port are closed with yellow mud before being poured, and high nickel matte pours into covers guarantor again after mold
Temperature lid.
The beneficial effects of the present invention are: (1) had both guaranteed the slow cooling task and high nickel matte slow cooling index of high nickel matte.
(2) guarantee high nickel matte physical appearance quality.
(3) using effect for improving high nickel matte mould, reduces the generation of mould craze and transfiguration phenomenon.
(4) working service is simple, reduces post work labor intensity.
(5) spare part and Master Cost are reduced on year-on-year basis.
Detailed description of the invention
Fig. 1 is the overlooking structure diagram that high nickel matte pours mold body；
Fig. 2 is the side structure schematic view that high nickel matte pours mold body；
Fig. 3 is the schematic diagram that high nickel matte pours mold insulation cover.
Specific embodiment
Such as Fig. 1,2,3, a kind of high nickel matte slow cooling mold, which is made of body and insulation cover, body big, bottom suitable for reading
Small, inner surface is inclined-plane, and there are four rounded corner, side wall and bottom plates to be also made into arc transition for side wall, is respectively equipped on two opposite side
Symmetrical clamp port 1, for body by steel fibre pouring material monoblock cast, it is suitable for reading that insulation cover is covered on body.Divide on another two opposite side
Not She You convex block 2, convex block 2 be equipped with annular groove.Convex block is used to facilitate handling around wirerope.The design of rounded corner, arc transition makes
Uniform force avoids stress from concentrating, and body is not easily susceptible to cracking.
For insulation cover equipped with lower along side 3, heat preservation cover material is heat-resisting cast iron, and lifting lug is arranged at top, and lifting lug is used to that crane is cooperated to rise
It hangs.It is lower that height is determined according to body volume and upper open area along side 3, it is ensured that high nickel matte upper surface rate of heat dispation and side wall and bottom
Being consistent property of heat conduction rate, high nickel matte entirety slow cooling works well
It is cast using above-mentioned mold, the high nickel matte of slow cooling, the ground inside workshop is digged pit, and is cheated as pyramid, bottom surface sands
Layer, angle scrapes out arc transition, mold is put into hole, on mold along near coal-mine concordant, between mold and hole gap sand
Rammed earth.Uniformly (modes such as electromagnetic heating, Hot-blast Heating can also shift the high nickel matte block of solidification for preheating before casting
Into mold, 50-60 degree inside high nickel matte block, surface layer 30-40 degree, it places 8-12 hours, is preheated using high nickel matte block waste heat,
Mold is heated more evenly, using this preheating method, multiple molds is needed to be used alternatingly), with anti-cracking.Clamp port is sealed with yellow mud
It closes, high nickel matte covers insulation cover after pouring into mold immediately, to guarantee to melt the high abundant slow cooling in nickel matte upper surface.It is beaten after slow cooling
Insulation cover is opened, the high nickel matte block of the solidification at clamp port is clamped with clamp, opens high nickel matte block with mold separation.
Using improved slow cooling mold, the service life of nickelic sulfonium slow cooling mold both can guarantee, while guaranteeing high nickel matte
Slow cooling effect.
