Description
Изобретение относитс к области литейного производства и может быть широка использовано в промышленности при литье а.чюминиевых сплавов под давлением.The invention relates to the field of foundry and can be widely used in industry for casting aluminum and alloys under pressure.
Известна смазка, включающа в качестве га.Югенида щелочного металла калий йодистый 1.A lubricant is known which includes potassium iodide 1 as alkali metal alkaline ha.
Однако эта смазка не устран ет привар зализаемого алюминиевого сплава к поверхности пресс-формы.However, this lubricant does not eliminate the weld of the aluminum alloy alloyed to the surface of the mold.
Наиболее близкой к изобретению по технической суш,ности и достигаемому результату вл етс смазка, включающа глицерин , едкое кали и воду 2 .Closest to the invention in technical drying, and the result achieved is a lubricant comprising glycerin, caustic potash and water 2.
Така смазка не обеспечивает достаточной чистоты поверхности отливок.Such lubrication does not provide sufficient cleanliness of the casting surface.
Целью изобретени вл етс повыщение качества поверхности отливок и обеспечение механизированного нанесени смазки.The aim of the invention is to increase the quality of the surface of the castings and provide mechanized lubrication.
Это достигаетс тем, что смазка дополнительно содержит калий йодистый при слеингредиентов , вес./о;:ующе .м соотношении 0,5-5,0 This is achieved by the fact that the lubricant additionally contains potassium iodide with the following ingredients, w / v;: the ratio is 0.5-5.0
Калий иоди:11лй 0,5-2,0 Potassium iodine: 11th 0.5-2.0

В таблппе приведены составы смазок.The table contains lubricant compositions.
Усилие извлечени стержн из отливки при нанесении на пресс-форму смазки 1-4,5 т, смазки Н-4,2 т, смазки П1 - 4,5 т.The effort to remove the core from the casting when applied to the mold lubricant 1-4.5 tons, lubricants H-4,2 tons, lubricants P1 - 4.5 tons.
Нижний предел ингредиентов смазки определ етс услови ми удовлетворигельного извлечени отливок из пресс-форм. ВерхНИИ предел ингредиентов .обусловливает возможность получени отливок с чистой поверхностью .The lower limit of the lubricant ingredients is determined by the conditions for satisfactorily removing the castings from the molds. The upper limit of ingredients limits the possibility of obtaining castings with a clean surface.
Реа.чизаци изобретени позволила снизить брак отливок по иригарч.The re-engineering of the invention allowed the reduction of the irrigarch castings.
