Description
ИзобретениеInvention
относитс к черной металлургни , в частности к составам теплоизолирующих смесей, примен емых, например, при рг:зл 1вхе металла, а также к лромышленност )1 стро;1тельных материалов.It relates to ferrous metallurgy, in particular, to the compositions of heat insulating mixtures used, for example, with rg: zl 1x metal, as well as from industry 1) building materials.
Известны экзотермические и теплоизолирующие смеси на основе асбоцемента, слюд ,ной чешуйки, дерез вных опил, циносферных смесей. Однако они характеризуютс иедостаточной эффективностью утеилеин , например , металла при его разлинке, выделением ;пыли и газа в случае использовани слюд ной чешуйки, асбестита, графита и сел.итры.Exothermic and heat insulating mixtures based on asbestos-cement, mica, noi flakes, wood sawdust, and cynospheric mixtures are known. However, they are characterized by inadequate efficiency of uteilein, for example, metal when it is cast, the release of dust and gas in the case of mica flakes, asbestosite, graphite and potassium.
Дл снижени потерь тепла при кристаллизации металла, что повышает его качество, предлагаетс хомпоненты брать -в следуюш,е,м соотнсше;нии, вес. %:To reduce heat loss during the crystallization of the metal, which improves its quality, it is proposed that the components be taken in the following, e, m ratio, weight. %:

В качестве волокнистого низкотеплопроводного материала примен ют шлаковую вату илм стекловату, или минеральную вату в ко . личестве 30-75%; «роме того, ш качестве волОкнистого низкотеплопроводного материала ввод т каолиновое волокно. Олнеуиорны.м материалом служит любой огнеупорный материал , например шамот, глина, дуиит, магнезит , песок, кварцит, бетоны, огнеупорные смеси. В качестве св зующего использ ют пульве1рба;;елит, жидкое стекло, мел ссу, синтетические смолы и л.р.Slag wool or glass wool, or mineral wool, is used as a fibrous low-heat conductive material. the amount of 30-75%; In addition, kaolin fiber is introduced as a volcanic low-heat conductive material. Olneuiorm materials serve as any refractory material, such as chamotte, clay, duiite, magnesite, sand, quartzite, concrete, refractory mixtures. Pulveler is used as a binder; elite, water glass, chalk ssu, synthetic resins, and l.
Описываема теплоизолирующа смесь имеет низкую теплопроводность н не расплавл етс при утеплении зеркала металла. Из лее можно прессовать уте:1л юш,ие дис/ки и плиты.The described heat insulating mixture has a low thermal conductivity and does not melt when the metal mirror is insulated. From this, you can extrude the soldering: 1 l yush, dis / k and plates.
