Description

Предметом изобретени   вл етс  кокиль дл  отливки детален из белого чугуна, изготовленный из стали или чугуна.The subject of the invention is a chill mold for casting a detail of white cast iron made of steel or cast iron.

Преимуш,еством от.тивки деталей из белого чугуна в металлические (JDopMbi  вл етс  увеличение в нем числа центров графитизании. получение мелкозернистой структуры. При этом большое значение имеет обеспечение максимальной теплоотдачи от залитого металла на форму.The advantage is that the white iron parts are machined into metal parts (JDopMbi is an increase in the number of graphitization centers in it. Obtaining a fine-grained structure. It is of great importance to ensure maximum heat transfer from the cast metal to the mold.

Одной из основных причин, резко снижающих теплоотдачу,  вл етс  наносима  на форму специальна  теплоизол ционна  облицовка (обмазка ) , а также слаба  тенлопроводность чугунных и стальных форм.One of the main reasons for drastically reducing heat transfer is the special heat insulating lining (plastering) applied to the mold, as well as the weak tenacity of the cast iron and steel molds.

- Кроме того, нанесенна  ка металлическую форму облицовка порождает брак по газовы.м раковинам и рыхлотам вследствие выгорани  в ней отде тьных компонентов.“In addition, the lining applied to the metal form generates a defect in gas shells and looses due to burnout of individual components in it.

К, недостаткам чугунных и стальных форм следует отнести их малу;о стойкость ввиду неоднократных н резких нагревов внутренних новер.хностей , соприкасающихс  с заливаемым металлом.The disadvantages of cast-iron and steel forms should be considered as small; about resistance due to repeated and abrupt heating of internal innovations that are in contact with the metal being poured.

Кокиль, согласно изобретению, не имеет указанных недостатков. Это достигаетс  тем, что его внутренн   (рабоча ) поверхность облицована слоем меди. Толщина облицовки меди зависит от объема заливаемого металла, от его температуры и колеблетс  от 5 до 30 мм. Крепление об.пщовочного сло  может быть механическое или путем наплавки (заливки меди на стальное и.щ чугунное основание), с последующей обработкой соответствующего контура.Chill mold, according to the invention, does not have these disadvantages. This is achieved by the fact that its internal (working) surface is lined with a layer of copper. The thickness of the copper lining depends on the volume of the metal being poured, on its temperature, and ranges from 5 to 30 mm. The fastening of the basement layer can be mechanical or by overlaying (pouring copper onto a steel cast iron base), with subsequent processing of the corresponding contour.

Основное назначение сло  меди - интенсивный отво/т, тепла от залитого метаЛоТа (отливки), в результате чего мгновенно образуетс  плотна  поверхностна  корка с мелкозернистой структурой, котора  быстро растет по толщине, значитатьно сокраща  врем  кристаллизации отливки.The main purpose of the copper layer is intense otv / t, heat from the poured metaLOTA (casting), as a result of which a dense superficial crust with a fine-grained structure, which quickly grows in thickness, is formed, which shortens the crystallization time of the casting.

При заливке бедного чугуна в облицованные медью формы не наблюдаетс  оплавлещш и сваривани  форм с отл 1вкой без наличи  какоголибо покрыти  их обмазкой или краской, кроме того, срок службы кокил  значительно повышаетс .When casting poor cast iron into copper-lined molds, no melting or welding of molds with casting is observed without any coating of paint or paint, and the service life of the mold is significantly increased.

Предмет изобретени Subject invention

Кокиль дл  отливки деталей из белого чугуна, изготовленный из стали или чугуна, отличающийс  тем, что, с целью повышени  качества отливки и удлинени  срока службы кокил , лзнутренн   (рабоча ) поверхность его облицована слоем .меди от о до 30 мм.Chill mold for casting white iron parts made of steel or cast iron, characterized in that, in order to improve the quality of the casting and extend the service life of the chill mold, its internal (working) surface is lined with a layer of media from about 30 mm.
