Description
В технологии точного лить по выплавл емым модел м используютс различные составы упрочн ющих огнеупорных покрытнй, также известны отдельные способы нанесеии их на поверхность моделей.In the technology of precision casting on melted models, various compositions of reinforcing refractory coatings are used, and separate methods are also known for applying them to the surface of models.
В предлагаемом способе, с целью упрочнени облицовочного ortieynopпого сло , применено комбинированное нанесение одного или двух лицевых огнеупорных покрытий, изготовл емых на жидком стекле, обработанном нашатырем, и одного или двух последующих упрочн ющих покрытий , также изготовл емых на жидком стекле без какой-либо его обработки.In the proposed method, in order to strengthen the facing or tie layer, combined application of one or two front refractory coatings made on liquid glass treated with ammonia and one or two subsequent strengthening coatings, also made on liquid glass without any processing.
В качестве исходных материалов дл огнеупорных покрытнй используютс : пылевидный кварц, любое жидкое стекло, кварцевый песок и закрепитель - раствор нащатыр .The following materials are used as raw materials for refractory coatings: pulverized quartz, any liquid glass, quartz sand and a fixative - a solution of naschatat.
Описываемый способ нанесени огнеупорного покрыти на поверхность выплавл емых моделей не требует дефицитных материалов (этилсиликата, спирта) и может с успехом примен тьс в промышленности .The described method of applying a refractory coating to the surface of the models produced does not require scarce materials (ethyl silicate, alcohol) and can be successfully used in industry.
Предмет изобретени Subject invention
Способ нанесени огнеупорного покрыт 1 на поверхность выплавл емых моделей при точном литье, отличаю щ н и с тем, что, с целью упрочнени облицовочного сло , нанесение первых покрытий осуществл етс на жидком стекле, обработанном нашатырем и одного или последующих унрочн ющнх покрытий на жидкол стекле, не подвергающихс никакой обработке.The method of applying a refractory is coated with 1 on the surface of the models produced during precision casting, which is different from the fact that, in order to strengthen the facing layer, the first coating is applied on liquid glass treated with ammonia and one or subsequent unary coating on liquid glass not subjected to any processing.
