Description

При изготовлен и литейных форм и стержней в качестве крепител.ч (св зующего) примен ютс  различные виды цементов. Широкого расп; )остр, в литейком производстве зти цементы не получили вследствие специфичной ДЛЯ цементов способности быстро отвердевать после затвореш-  водой при обычной температуре и превращатьс  в камневидное тело.In the manufacture of both molds and cores, various types of cements are used as fasteners (binder). Wide spread; ) In the foundry industry, these cements did not receive due to the specificity for cements, the ability to quickly solidify after shutter-water with water at ordinary temperature and turn into a stone-like body.

Специфические трудности возникают при исиользованин цементов дл5 1 роизводства литейных стержней в конвейерном фасонном литье; этп труднсстп сссбзнио велики дл  тех видов цеме1-:тов, которые относ тс  к группе быстрссхватьтающихс  цементов.Specific difficulties arise with the use of cements for the production of casting cores in conveyor shaped casting; This range of hardness is great for those types of cements: that belong to the group of high-speed cements.

Отмечено, что обэж/кенный при 1500 магнезитовый порошок (так называем)11Й, металлургическтй), неспособный при обычных телшературах к схпатьи,5апи1о с раствором хлористого магни , в отличие от обон женвого при 800 гюрошка (так называемого, каустического магнезита) приобре1ает способность тве эдеть в случае иагрева.It is noted that an obej / kenny (at 1500) magnesite powder (so-called) 11J, metallurgic), which is not capable of combining magnesium chloride with ordinary tsilavir, acquires the ability of magnesium chloride at 800 gyuroshka (the so-called caustic magnesite). to ede in case of iagrev.

Предлагаетс  использовать зти свойства, и при изготовлении св зующего ДЛЯ формовочных и стержневых масс, состо щего из хлористого магни  ИЛИ другой хлористой СОЛИ и обожженного магнезита, примен ть в качестве последнего металлургический, т. е. обожженный при 1500° л:агиезитовый порошок.It is proposed to use these properties, and in the manufacture of a binder FOR molding and core masses consisting of magnesium chloride OR other SALT chloride and calcined magnesite, use metallurgical as the latter, i.e., calcined at 1500 ° L: agesite powder.

Обыппзги стержневой песок смешивают с 10-20% по весу измельченного в ПЫЛЬ высокообожженного магнезитового порошка, и с 10-20,i; о весу раствора хлористого магни , карналлита, сернокислого магни . уд. веса более 1,100 и т. п. солей, с добавлением в смесь при надобностг. ГЛИНЫ. Получают массу с многочасовым сроком годности дл  изготовлеии  .читейных стержней и форм.The sand from the sand is mixed with 10–20% by weight of highly calcined magnesite powder ground in DUST, and 10–20, i; about the weight of a solution of magnesium chloride, carnallite, magnesium sulphate. beats. weights of more than 1,100, etc., salts, with the addition to the mixture when needed. CLAYS. A mass with a shelf life of several hours is obtained for the fabrication of core rods and molds.

Процесс обезвоживани  н твердени  св зующего осуществл етс  :в обычных сушнлках.The process of dewatering and curing the binder is carried out: in conventional dryers.
