Description

tipi изготовлении различных изде .1ИЙ из литого базальта, диабаза и т. п. встречаетс  необходимость в получении в этих издели х отверстий ма .юго диаметра (например, в наконечниках дл  пескоструйных аппаратов, ;5 мннах дл  карандашных фабрик, 3 центробежных насосах дл  кислот и т. п.), дл  чего в формы вставл ют cooTBeTCTByrouuie стержни. Работа Стержн  при литье из диабаза отличаетс  чрезвычайно т желыми усло:-;и ми: изготовленный и просушенный стержень должен выдержать без деформан ий нагрев в форме до 700. Поэтому стержень должен быть достаточно нрочен в этих температур 5ых услови х; стержень не должен провисать под вли нием собственного веса, но в то же врем  должен быть и настолько м гким, чтобы легко выбиватьс  в гор чем состо нии из издели , если изделие освобон даетс  от стержн  до его методического охлаждени , и не должен прен тствовать возможности усадки издели  нри охлаждении, так как слишком твердый стержень рвет отливку на части. Наконец, стержень должен обладать тугоплавкостью (примерноTipi making various products from molded basalt, diabase, etc., there is a need to obtain openings of any diameter in these products (for example, in tips for sandblasting machines,; 5 mn for pencil factories, 3 centrifugal pumps for acids and so on), for which cooTBeTCTByrouuie rods are inserted into the molds. The work of the core in the casting of diabase is extremely difficult under the conditions of: -; and mi: the made and dried core must withstand heat up to 700 without deforming. Therefore, the core must be sufficiently strong at these temperatures of the 5th condition; the rod should not sag under the influence of its own weight, but at the same time it should be so soft that it is easy to knock out in a hot state of the product, if the product is released from the rod before its methodological cooling, and should not prevent shrinkage of the product when cooled, as a too hard core tears the casting to pieces. Finally, the rod must have refractoriness (approximately

до 1250) п должен легко разруп атьс , чтобы обеспечить достаточную чистоту канала. Изготовл емые ранее дл  достижени  указанных целей стержни из кварцевого песка с каолином или с цементом сплавл лись с телом издели  или рвали его на части , так как были слишком крепкими.to 1250) n must be easily disassembled to ensure sufficient purity of the channel. To achieve the above objectives, rods made of quartz sand with kaolin or with cement were previously fused with the body of the product or were torn to pieces, because they were too strong.

По предлагаемому способу стержни изготовл ютс  из графита (70-90%), сменшнного с огнеупорной глпной или каолином (30-100%).In the proposed method, the rods are made of graphite (70-90%), replaced with a refractory core or kaolin (30-100%).

Суха  смесь указанных .iaтepиaлoв тщательно перемешиваетс , увлажн етс  до возможности формоватьс , тщательно проминаетс  дл  удалени  включенных в массу пузырьков воздуха , а потом формуетс  обыкновенным способом, несколько подсушиваетс  на воздухе и ставитс  в форму дл  окончательного просушивани  и прокалки.The dry mixture of the indicated varieties is thoroughly mixed, moistened until it can be molded, thoroughly rinsed to remove the air bubbles included in the mass, and then molded by the usual method, dried several times in air and placed in a mold for final drying and calcining.

После окончани  нроцесса или даже после методического охлаждени  его в туннельной печи стержень этого состава чрезвычайно легко разрушаетс , дава  достаточно чистую поверхность канала.After termination of the process, or even after its methodological cooling in a tunnel kiln, the rod of this composition is extremely easily destroyed, giving a sufficiently clean channel surface.
