Description
II
Изобретение относитс к области литейного производства, а именно к производству металлургических поддонов дл разливки стали.The invention relates to the field of foundry, namely the production of metallurgical pallets for steel casting.
Известен способ получени литых биметаллических изделий путем последовательной заливки двух металлов, состо щий в том, что после заливки порции расплава па его поверхность дл защиты от окислени и охлаждени нанос т жидкий шлак, а затем заливают новую порцию расплава дл образовани следующего сло .A known method for producing cast bimetallic products by successive pouring of two metals consists in the fact that after pouring a portion of the melt on the surface, liquid slag is applied to protect it from oxidation and cooling, and then a new portion of the melt is poured to form the next layer.
Однако применение такого снособа недостаточно дл надежного соединени обоих слоев, например, при получении биметаллических поддонов (стальной рабочий слой на чугунной основе) с высокой стойкостью против образовани сетки разгара и короблени .However, the use of such a cut is not enough for a reliable connection of both layers, for example, in the preparation of bimetallic pallets (steel working layer on a cast-iron base) with high resistance to the formation of a grid of heat and distortion.
Цель изобретени - обеспечение надеж-ного соединени слоев поддона.The purpose of the invention is to provide a reliable connection of the layers of the pallet.
Дл этого поверхность жидкой стали покрывают слоем графита или другого углеродсодержащего материала толщиной 5-20 мм. Содержание углерода в поверхностном слое стали повышаетс с 0,15-0,3 до 0,8%, что вызывает понижение температуры плавлени на 40-50°С. Дл надежного соединени слоев выдержка перед заливкой чугуна должна составл ть 1-10 мин в зависимости от размеров ОТЛИВКИ.To do this, the surface of the liquid steel is covered with a layer of graphite or another carbon-containing material with a thickness of 5-20 mm. The carbon content in the surface layer of steel increases from 0.15-0.3 to 0.8%, which causes a decrease in the melting temperature by 40-50 ° C. For a reliable connection of the layers, the shutter speed before pouring the cast iron should be 1-10 minutes, depending on the size of the CAST.

Способ изготовлени литых биметаллических поддонов, включающий заливку сло расплава, нанесение на -него защитного покрыти , а затем заливку второго сло , отличающийс тем, что, с целью обеспечени надежного соединени слоев поддона, в котором нижний слой состоит из стали, а второй из чугуна, в качестве защитного сло нанос т углеродсодсржащий материал толщиной 5-20 мм, а второй слой ноддона заливают через 1 - 10 мин.A method of manufacturing cast bimetallic pallets, comprising pouring a layer of melt, applying a protective coating on it and then pouring a second layer, characterized in that, in order to ensure a reliable connection of the layers of the pallet, in which the bottom layer consists of steel, and the second of cast iron, Carbonaceous material with a thickness of 5–20 mm is applied as a protective layer, and the second layer of a noddon is poured in 1–10 minutes.
