Description

В насто щее врем  топливники дл  .автомобильных газогенераторов изготовл ютс  из стали С: последующим .алитированием.At the present time, fireboxes for automotive gas generators are made of steel C: subsequent.

Стальное литье дает повыщенный брак и излишний расход металла, вследствие необходимости увеличени  толщины стенок из-за пониженно-й жидкотекучести стали.Steel casting results in increased scrap and excessive metal consumption due to the need to increase wall thickness due to the reduced fluidity of steel.

Попытки изготовить подобные тапливники из ковкого чугуна до сих пор не увенчали сь успехом, вследствие непрочности алитированного сло  и малой стойкости топливников.Attempts to make similar taplives from malleable cast iron have not yet been crowned with success, owing to the weakness of the aluminized layer and the low resistance of the fireboxes.

Предлагаемый способ изготовлени  топлиеников позвол ет получать из ковкого чугуна топливники с достаточно прочным алитировйнным слоем и, следовательно, вполне удовлетвор ющие требовани м стойкости. Способ этот заключаетс  в том, что химический состав чугуна подбирают таким образом, чтобы, в резул;ьтате отжига по европейскому способу, в руде были обеспечены минимальное количество углерода в центре и об зательна  ферритова  корка на поверхности, подлежащей алитироваиию.The proposed method for the production of topenics allows to obtain from malleable iron castlings with a sufficiently strong aluminized layer and, therefore, fully satisfying the requirements of durability. This method consists in that the chemical composition of the iron is selected so that, as a result of annealing by the European method, the minimum amount of carbon in the center and the ferrite crust on the surface to be aluminized are provided in the ore.

Дл  отливки предлагаетс  чугуй следующего состава (в «/о):For casting, cast iron is offered of the following composition (in "/ o):

кремни 0,5-0,8silicon 0.5-0.8

Miiprainia0,8-1,2Miiprainia0.8-1.2

серы0,1-0,15sulfur 0,1-0,15
