Abstract
The invention discloses a demoulding agent for an iron casting apparatus and a producing method thereof. The components and content of the demoulding agent are: 80-120 parts of blast furnace cloth bag dust removing ash; 3-7 parts of calcium oxide; 1000-1500 parts of water. The producing steps are: preparing each component according to the content parts, mixing the prepared blast furnace cloth bag dust removing ash and the calcium oxide, mixing water of predetermined parts thereto evenly to form the demoulding product which is finally attracted by a high-pressure water pump into a spray tube and is sprayed onto the inner surface of the iron casting mould. The invented method reduces transport distance of the blast furnace cloth bag dust removing ash, so that the probability of secondary pollution caused by raised dust thereof is reduced; large amount of coal slurry is saved so as to achieve energy saving object and reduce the cost at the same time; leadless during demoulding process improves the working condition of the iron casting apparatus. Adhesion of a small amount of blast furnace cloth bag dust removing ash can improve revolving furnace working condition properly.
Description
Technical field:
The present invention relates to a kind of releasing agent and preparation method thereof, specifically a kind of mold lubricant for iron casting machine and preparation method thereof.
Background technology:
Pig machine is a mechanized equipment of iron liquid being cast continuously iron block, and iron liquid is cast in the pig mold and becomes iron block through more than half circulation after coagulation, is shed in the chute by the gravity effect from pig mold.The effect of releasing agent is exactly to form the slurry protective layer at the pig mold inner surface, guarantees that iron block and swage do not bond.Play and guarantee carrying out continuously and equipment intact of casting.
The existing pig machine releasing agent of China is mainly formed according to the certain proportion configuration by following several batchings: coal slime (or lead powder), lime, water.Wherein coal slime is a kind of available energy, and lead powder then has bigger toxicity to human body, to the workman of long-term work is healthy quite big influence is arranged.Pig machine cast iron is generally the steel-making pig iron and foundry pig iron at present, and wherein the former accounts for the overwhelming majority.Casting iron ingot upward, accompanying a small amount of coal slime has strengthened the workload of pneumatic steelmaking decarburization undoubtedly.The furnace cloth bag dust-removing ash is as the middle byproduct in a kind of metallurgical process, and it utilizes bigger limitation always.Be used for sintered material at present mostly, but this purposes still has great deficiency: at first, the ferrous grade of furnace cloth bag dust-removing ash is too low, and iron-holder is generally 20%～40%.Participate in the grade that sintered material has greatly reduced sintering deposit; Secondly, the granularity of furnace cloth bag dust-removing ash is too thin, must handle before transporting the sintering mill (plant) to, otherwise secondary pollution such as airborne dust very easily occur; Once more, surpass the paste knot that certain ratio will cause the sintering machine furnace grid in sintering deposit, damage agglomerating plant if the furnace cloth bag dust-removing ash adds.The furnace cloth bag dust-removing ash has reproducibility, and physicochemical property is better, and the possibility of carrying out again secondary response with molten iron is extremely low, and nonwetting molten iron is used as the technical conditions of pig machine releasing agent again.
Summary of the invention:
Technical problem to be solved of the present invention is at the prior art weak point, a kind of mold lubricant for iron casting machine and preparation method thereof is provided, by utilizing the performance of furnace cloth bag dust-removing ash, mix the releasing agent that the back forms a kind of new pig machine by quick lime and water then, provided the technical scheme of its preparation method simultaneously.
The present invention solves the technical scheme that its first technical problem adopts: a kind of mold lubricant for iron casting machine, and the component of its releasing agent and content are:
1000～1500 parts in 3～7 parts of water of 80～120 parts of quick limes of furnace cloth bag dust-removing ash.
A kind of mold lubricant for iron casting machine, the preferred ingredients of its releasing agent and content are:
1200～1400 parts in 4～6 parts of water of 90～110 parts of quick limes of furnace cloth bag dust-removing ash.
A kind of mold lubricant for iron casting machine, component of the best of its releasing agent and content are:
1300 parts in 5 parts of water of furnace cloth bag dust-removing 100 parts of quick lime of ash.
The particle diameter of furnace cloth bag dust-removing ash is smaller or equal to 50 microns.
The present invention solves its second technical scheme that technical problem adopted: a kind of mold lubricant for iron casting machine, and its preparation method step is:
Mark content according to component has been equipped with each component, earlier after furnace cloth bag dust-removing ash of getting ready and the quick lime mixing, place under the pig machine, utilize the pig machine cooling water sneak into the water of getting umber ready mix the releasing agent finished product, evenly be sprayed into the pig mold inner surface by high-pressure hydraulic pump suction to spray pipe at last.
A kind of mold lubricant for iron casting machine of the present invention and preparation method thereof is compared with prior art, has following beneficial effect:
A kind of mold lubricant for iron casting machine of the present invention produces the possibility of secondary pollutions such as airborne dust thereby the transportation range that has reduced the furnace cloth bag dust-removing ash has greatly reduced it; Save a large amount of coal slimes and reach energy saving purposes, reduced the cost of cast iron simultaneously; The unleaded working condition that improves pig machine of knockout course.
In the steelmaking process, the adding of a small amount of coal slime has increased the decarburization pressure of converter in the pig iron.Adhering to of a small amount of dedusting ash then can utilize the small amounts iron that wherein contains as passing oxygen agent increaseization slag speed, suitably improves the converter condition of work.
On the inner surface attached to mold, chemical property is stable effectively for releasing agent of the present invention, forms effective separation layer between molten iron and mold.Pig machine does not need extra knocking to get final product the demoulding, the ingot iron smooth surface that casts out, and this releasing agent has no side effect to human body.
