Description
Изобретение относитс к литейному производству и может быть использовано дл изготовлени литейных форм и стержней их холоднотвердеющих фосфатных смесей .The invention relates to foundry and can be used to make casting molds and cores of their cold-hardening phosphate mixtures.
Цель изобретени - снижение температуры разогрева смеси после отверждени и улучшение ее выбиваемости.The purpose of the invention is to reduce the heating temperature of the mixture after curing and improve its knockability.
Смесь содержит огнеупорный наполнитель , фосфатное св зующее и трифолин.The mixture contains refractory filler, phosphate binder and trifolin.
В качестве огнеупорного наполнител используетс кварцевый песок. Св зующим вл етс алюмоцинкмагнийфосфатное св зующее следующего химического состава.Quartz sand is used as a refractory filler. The binder is an aluminum zinc magnesium phosphate binder of the following chemical composition.
мас.%: окись цинка 2,9-3,1; окись алюмини 4,0-4,2; окись магни 2.9-3,1; фосфорный ангидрид 40,0-42.0; вода остальное.wt.%: zinc oxide 2,9-3,1; alumina 4.0-4.2; magnesium oxide 2.9-3.1; phosphoric anhydride 40.0-42.0; water the rest.
Трифолин вл етс железооксидным неорганическим пылевидным материалом и служит отвердителем. Трифолин используют следующего химического состава, мас.%; окись железа РеаОз 62.0-75.0; закись железа FeO 25,0-38.0,Trifoline is an iron oxide inorganic pulverized material and serves as a hardener. Trifolin use the following chemical composition, wt.%; iron oxide ReaOz 62.0-75.0; iron oxide FeO 25.0-38.0,
Введение в состав смеси фосфатного св зующего на основе фосфорного ангидрида и окислов алюмини , магни и цинка способствует снижению реакционной способности его к окислам железа, за счетThe introduction of a mixture of phosphate binder based on phosphoric anhydride and oxides of aluminum, magnesium and zinc to the composition helps to reduce its reactivity to iron oxides, due to

чего снижаетс температура разогрева смеси , благодар чему снижаетс брак форм и стержней из-за трещин.which reduces the temperature of heating the mixture, thereby reducing the marriage forms and rods due to cracks.
Смесь готов т следующим образом. Кварцевый песок тщательно перемешивают с трифолином в течение 1,5-2,0 мин. Затем добавл ют фосфатное св зующее и ингредиенты смеси дополнительно перемешивают в течение 2.0-2.5 мин. Из приготов- ленной смеси изготавливают формы и стержни традиционными способами.The mixture is prepared as follows. Quartz sand is thoroughly mixed with Trifoline for 1.5-2.0 minutes. The phosphate binder is then added and the ingredients of the mixture are further mixed for 2.0-2.5 minutes. Forms and cores are made from the prepared mixture using traditional methods.
Составы смесей и их технологические и физико-механические свойства приведены в таблице.The compositions of the mixtures and their technological and physico-mechanical properties are given in the table.
Как видно из данных, приведенных в таблице, предлагаема смесь по сравнению с известной имеет лучшую выбиваемость. Кроме этого, улучшаютс санитарно-гигиенические услови труда за счет исключени из состава смеси ортофосфорной кислоты, снижаетс брак стержней и форм по трещинам из-за снижени перепада температур их по сечению.As can be seen from the data presented in the table, the proposed mixture has a better bendability compared to the known one. In addition, sanitary and hygienic working conditions are improved due to the exclusion of orthophosphoric acid from the mixture, the waste of rods and molds due to cracks is reduced due to a decrease in their temperature difference over the cross section.
