Description

СПОСОБ ПРОИЗВОДСТВА ИГОЛЬЧАТЫХ РЕКУПЕРАТОРОВMETHOD OF MANUFACTURE OF NEEDLE RECOVERORS

За влено 19  нвар  1949г. за №. 390469 в Гостехннку СССРFiled January 19, 1949. for no. 390469 in the State Technical Committee of the USSR

Дл  использовани  тепла отход щих газов металлургических и нагревательпых печей широко примен ютс  рекуперативные установки.Recuperative units are widely used to utilize the heat from the waste gases of metallurgical and heater furnaces.

При отливке игольчатых рекуператоров примен ютс  три марки жаростойких хромистых чугунов с содержанием хрома 1,2-1,75%, 13-14% и 30%.In the casting of needle heat exchangers, three grades of heat-resistant chromium cast irons with a chromium content of 1.2-1.75%, 13-14% and 30% are used.

Отливка рекуператоров из высокохромистых чугунов (с содержанием хрома 14% и 30%) св зана с большими трудност ми, причем плавка металла производитс  в электропечах.The casting of recuperators from high-chromium cast irons (with a chromium content of 14% and 30%) is very difficult, and the smelting of the metal takes place in electric furnaces.

Описываемый способ отличаетс  тем, что дл  отливки игольчатых рекуператоров примен етс  высококремпистый чугун с содержанием кремни  5-6%, а дл  труб длиною свыше 1300мм-с содержанием кремни  5-6% и хрома 0,5-1%. Содерл ание остальных элементов, кроме углерода, соответствует обычному серому чугуну. Механическа  указанных марок чугуна вполне достаточна дл  данного вида лить .The described method is characterized in that high-melting cast iron with a silicon content of 5-6% is used for casting heat exchangers, and for pipes over 1300 mm long with a silicon content of 5-6% and chromium 0.5-1%. The maintenance of other elements, except carbon, corresponds to the usual gray cast iron. The mechanical specified cast iron grades are ample for this type of casting.

В результате изготовлени  игольчатых рекуператоров из высококремнистого чугуна наблюдаетс  значительна  экономи  феррохрома, создаетс  возможность плавки чугупа в вагранке и возможность получени  высокого качества отливки игольчатых рекуператоров, ввиду наличи  исключительно хороших литейных свойств высококремнистого чугуна.As a result of the fabrication of needle heat exchangers from high silicon iron, significant savings in ferrochrome are observed, the possibility of melting pig iron in the cupola and the possibility of obtaining high quality needle heat recuperators, due to the extremely good casting properties of high silicon iron.

Предмет изобретени Subject invention

Способ производства игольчатых рекуператоров,, отличающийс  тем, что игольчатые рекуператоры отливаютс  из чугуна с содержанием: 2,6-2,8% углерода,, 5,0-6,0% кремни , 0,5-0,8% марганца и 0,5-1,0% хрома.Method for the production of needle heat exchangers, characterized in that the needle heat exchangers are cast from cast iron with the content of: 2.6-2.8% carbon, 5.0-6.0% silicon, 0.5-0.8% manganese and 0 , 5-1.0% chromium.
