Abstract
The present invention provides one kind with type chill and its preparation process, and described with type chill be by weight ratio is 9：1：0.02~0.03 steel wire cut pill, chromite sand, binder composition.The manufacture craft with type chill includes the following steps：A, raw material steel wire cut pill and chromite sand are proportionally mixed；B, the waterglass of a concentration of 52 ° of B é is added after raw material mixing, is mixed and is stirred evenly；C, after mixing, mixture is laid immediately on and is waited on appliance, blow carbon dioxide, make its hardening, be fabricated to type chill.The present invention prepare with type chill, the production is simple and convenient, shorten the production cycle, eliminate casting inclusion defect.
Description
Technical field
The present invention relates to casting technology fields, more particularly to one kind is with type chill and its preparation process.
Background technology
To increase the cooling velocity of casting part, the metal object placed in sand mold, sand core surface or cavity or its separate excitation
Cold object is known as chill.Chill can be used in various casting alloys, especially most with steel-casting application.Chill is used cooperatively with riser,
The consecutive solidification for reinforcing casting, improves the feeding efficiency of riser, prevents casting from generating shrinkage cavity or shrinkage porosite；Accelerate the cold of casting part
But speed makes casting tend both to solidify, and casting is prevented to be deformed and crackle；Accelerate the cold of the certain privileged sites of casting
But, to reach refinement matrix, the purpose of cast(ing) surface hardness and wearability is improved；It is difficult to that the portion of riser is arranged in casting
The plump protruding parts in position, especially casting part, shrinkage cavity or shrinkage porosite can be prevented by placing chill.
At present car panel die used in foundry production with type Chill be monoblock with type chill, deposit
Major defect be the process-cycle to grow (about 7 days), operation difficulty is big (monolithic weight about 10-20kg), is easy joining
Position destroy surface layer fireproof coating continuity, cause coating to rupture, enter in casting, formation be mingled with class defect, seriously
Shi Zaocheng product rejections.
Invention content
In view of this, the present invention is directed to propose one kind with type chill and its preparation process, to shorten the production cycle, simplifying work
People operates, and eliminates casting inclusion defect.
In order to achieve the above objectives, the technical proposal of the invention is realized in this way：
One kind is with type chill, it is characterised in that：Described with type chill includes steel wire cut pill, chromite sand, Binder Composition；
Steel wire cut pill, chromite sand, binder weight ratio be 9：1：0.018~0.027；
Further, chromite sand grain size is 40~70 mesh；
Further, a diameter of 3.0mm of steel wire cut pill；
Further, the binder is waterglass；
Further, the concentration of sodium silicate is 52 Baume degrees；
Further, include the following steps with type chill manufacture craft：
A, raw material steel wire cut pill and chromite sand are proportionally mixed and is stirred evenly；
B, it waits for the waterglass that a concentration of 52 ° of B é are added after raw material mixing, is mixed；
C, after mixing, mixture is laid immediately on casting mold, blows carbon dioxide, makes its hardening, is fabricated to type
Chill.
Further, the time that carbon dioxide is blown in step c is 1-2 minutes.
Compared with the existing technology, the present invention has the advantage that：
Steel wire cut pill interior tissue is tight, non-breakable, even particle size distribution, has hardness appropriate, and impact resistance is strong,
Long lifespan.In general, the service life of steel wire cut pill is 3000 --- it 3500 times, can recycle, its meeting in cyclic process
It slowly wears, becomes dust.Steel wire cut pill is non-breakable simultaneously, and relative impact strength is big, and the workpiece effect of cleaning is good, quality
It is high.Steel wire cut pill can also reduce dust pollution and mitigate worker's labour.
Be heated volume stability, thermal conductivity of chromite sand is high, not only has good alkali resistance slag when being contacted with molten metal
Effect and itself have the characteristics that solid-phase sintering not with the chemically reactives such as iron oxide, molten metal can be prevented well
Infiltration, avoid generate scab defect.
The preparation process of the present invention can shorten with the type chill production cycle, Production Time by shortening within 7 days 1 hour, together
When simplify operation, eliminate casting inclusion defect.
