Description
При изготовлении форм в производстве лить по вьшлавл емым модел м в качестве присыпочного материала в огнеупорном покрытии используют кварцевый песок, электрокорунд , силлимант, плавленый кварц.In the manufacture of molds in the production of casting on the famous models, quartz sand, electrocorundum, sillimant, fused quartz are used as a powder in the refractory coating.
Электрокорунд и силлимант обеспечивают получение форм хорошего качества, но дефицитны . Кварцевый песок обеспечивает хорошую поверхность, но форма недостаточно прочна и термоустойчива.Electrocorundum and sillimant provide forms of good quality, but are scarce. Quartz sand provides a good surface, but the form is not strong enough and heat resistant.
ПредлагаелМый способ заключаетс в том, что в качестве присыпочного материала дл второго и последующего слоев наносимой на блок суспензии используют шлак-отход ваграночного , доменного или мартеновского прОИЗводства .The proposed method consists in using slag-waste of cupola, blast-furnace or open-hearth production as a powder for the second and subsequent layers of the slurry applied to the block.
Дл первого сло покрыти в качестве присыпочного материала примен ют кварцевый песок, который обеспечивает чистоту поверхности отливок.For the first layer of coating, silica sand is used as the powder material, which ensures the cleanliness of the casting surface.
Применение дл присыпки второго и последуюш ,их слоев вместо кварцевого леска шлака позвол ет повысить прочность, термоустойчивость и газопроницаемость форм, а также уменьшить обезуглерол енный слой на поверхности отливок.The use of the second and subsequent layers for powder, instead of the quartz filament, makes it possible to increase the strength, heat resistance and gas permeability of the forms, as well as reduce the decarbonized layer on the surface of the castings.
Предмет изобретени Subject invention
Способ изготовлени форм в производстве лить по выплавл емым модел м с примепение .м кварцевого песка дл присыпки первого сло наносимой на блок суспензии, отличающийс тем, что, с целью улучшени качества отливок, дл присыпки второго и последующих слоев используют размолотый шлак-отход ваграночного, доменного или мартеновского производства.The method of making molds in the production of casting on melted models with the use of quartz sand to powder the first layer of the suspension applied to the block, characterized in that, in order to improve the quality of the castings, ground cupola slag is used to powder the second and subsequent layers, domain or open-hearth production.
