Cast iron plate material Introduction - gray cast iron
Gray cast iron is a commonly material used in the foundry industry , also known as cast iron. are the commonly materials of cast iron platform. So what gray iron is it that used for cast iron plate?
Cast iron plate with gray iron , there are two forms of carbon in iron : graphite and iron carbide . Graphite is a form of carbon , carbon- graphite flake , smooth and soft as a breeze , like , very strong. Graphite iron in the presence of iron-based bulk body fragmented , it seems there are a lot of iron in the strip holes , destroyed the iron ruggedness. This state exists in graphite carbon in the iron to iron dyed gray , so called gray iron . because the gray iron contains soft graphite , it is easy to cut when using it manufacturing mechanical parts .Graphite has a " lubricating " effect in the liquid molten iron , molten iron mobility, and adapted to make cast iron plate, so gray iron , also known as " cast iron ."
Iron carbide is white , it is hard and brittle , too many , will be like a stone pig iron brittle . With this production of iron parts, capable of smashing , breaking open the section is white , so called white iron . White iron is mainly used for steel making, steel making cast iron plate , called a "making steel ."
However, graphite and iron carbide also can be transformed into each other , there are two decisive conditions : First, the chemical composition of molten iron , it can promote the decomposition of iron carbide into graphite if the silicon content is high , the silicon content of cast iron is always high ; the second is the speed of solidification of molten iron , in the appropriate component , if the cold too fast, too late to iron iron carbide decomposition , it becomes white iron ; if cold slowly broken down into iron carbide and carbon and iron , so that it becomes gray iron .
Grey cast iron Arranging iron platform used mainly HT200-300, hardness can reach HB170-240. Our cast iron are excellent material , welcome to inquire.
