Description
Изобретение относитс к металлур гии, а именно к изысканию чугунов дл отливки изложниц. Известен чугун 1, содержащий, вес.%: Углерод3,8-4 ,3 Кремний0,2-1,2 Марганец0,2-1,2 Кальций0,02-0,05 Алюминий0,5-2,0 ЖелезоОстальное Недостаток известного чугуна сос тоит в невысокой окалиностойкости. Наиболее близким к предлагаемому по технической сущности и достигаемому результату вл етс чугун 2 следующего химического состава,вес Углерод3-4,5 Кремнийа,5-1,8 Марганец0,1-0,6 Магний0,03-0,1 Алюминий . 0,5-0,9 ЖелезоОстальное Однако указанный чугун характери етс недостаточно высокими прочност ростоустойчивостью и окалиностойкостью . Цель изобретени - повышение про ности, ростоустойчйвости и окалиностойкости . Поставленна цель достигаетс тем, что чугун, содержащий углерод, крем-з НИИ, марганец, магний, алюминий и железо , содержит эти компоненты в следующем соотношении, вес.%: Углерод , , 3,5-4,5 Кремний0,5-1,3 Марганец0,5-1,5 Магний . 0,15-0,3 АЛЮМИНИЙ0,01-0,28 ЖелезоОстальное В качестве примесей чугун может содержать серу в количестве 0,010 ,02 вес.% и фосфор - до 0,3 вес.%. Предлагаемый чугун имеет следующие свойства: окалинообразование 10,2511 ,78; термостойкость (нагрев до 900°С и последующие охлаждёни 280330 циклов ; .ростоустойчивость (увеличение длины образца диаметром 30 мм, длиной 150 мм после выдержки 150 ч) 0,06-0,65%; жидкотекучесть при температуре 1200-1250°С 380-400 Mivi. Пример. В производственных услови х выплавл ют передельный чугун с химсоставом верхнего, нижнего и среднего значений компонентов и одновременно выплавл ют чугун известного химсостава с верхним и нижним значением компонентов.The invention relates to metallurgy, namely, to finding cast irons for casting molds. Known cast iron 1, containing, wt.%: Carbon 3.8-4, 3 Silicon0.2-1.2 Manganese0.2-1.2 Calcium0.02-0.05 Aluminum0.5-2.0 IronOstal Other Lack of known cast iron sos Toit in low scale resistance. The closest to the proposed technical essence and the achieved result is cast iron 2 of the following chemical composition, weight: Carbon 3-4.5 Silicon, 5-1.8 Manganese 0.1-0.6 Magnesium 0.03-0.1 Aluminum. 0.5-0.9 Iron Other, However, the specified cast iron is not characterized by a sufficiently high resistance to corrosion resistance and scaling resistance. The purpose of the invention is to increase the stability, stability and scaling resistance. The goal is achieved by the fact that cast iron containing carbon, cream, research institutes, manganese, magnesium, aluminum and iron, contains these components in the following ratio, wt.%: Carbon, 3.5-4.5 Silicon 0.5-1 , 3 Manganese 0.5-1.5 Magnesium. 0.15-0.3 ALUMINUM 0.01-0.28 IronErestal As an impurity, the cast iron may contain sulfur in an amount of 0.010, 02 wt.% And phosphorus - up to 0.3 wt.%. The proposed cast iron has the following properties: scale formation 10.2511, 78; heat resistance (heating to 900 ° C and subsequent cooling of 280330 cycles; resistance to resistance (increase in the length of the sample with a diameter of 30 mm, a length of 150 mm after soaking for 150 hours) 0.06-0.65%; fluidity at a temperature of 1200-1250 ° C 400 Mivi. Example: Under production conditions, pig iron with the chemical composition of the upper, lower and average values of the components is smelted and cast iron of known chemical composition with the upper and lower values of the components is simultaneously smelted.
Химсостав чугунов приведен в табл. 1.The chemical composition of the cast iron is given in table. one.
В табл. 2 приведены механические свойства предлагаемого чугуна в сравнении с известным.In tab. 2 shows the mechanical properties of the proposed cast iron in comparison with the known.
Повышение прочности, окалиностойкости и ростоустойчивости предлагаемого чугуна позвол ет повысить качество отливок и их стойкость наIncreasing the strength, scaling resistance and high stability of the proposed cast iron allows improving the quality of castings and their resistance to
