Q:Who knows the proportion of pig iron and coke used in cupola?
Raw material input: the main raw materials for casting are pig iron, scrap steel, ferromanganese and so on. Normally, after melting, the proportion of pig iron and scrap steel is about 9:1, and the proportion of pig iron and scrap steel is about 6:4 in the dryer enterprises, and ferromanganese is put into the product according to the requirements. Because pig iron and scrap carbon content is not the same, pig iron containing higher carbon content, about 4 to 4.3, scrap carbon content is low, about 0.8.There is a doubt: if the proportion of scrap input is too large, easy to increase processing difficulties, product quality can not be guaranteed. The proportion is too high or too low is abnormal.
Q:What is ball cast iron?
Iron is an alloy of iron and carbon carbon content greater than 2.11%, the material industry of pig iron, scrap steel and alloy by high temperature melting and casting and, except for Fe, and also with other cast iron carbon graphite to form precipitation, if precipitation of graphite is the iron strip called gray iron or gray cast iron, cast iron is called the vermicular vermicular cast iron, flocculent is called white cast iron or iron, and is called the code of cast iron ductile iron ball at.
Q:What's the color of the pig iron?
Nodular cast iron: ductile iron to carbon in the form of spherical graphite, which is far better than the mechanical properties of gray cast iron and steel. Close to performance: excellent casting, machining and wear resistance, and has certain elasticity. Ductile iron foundry is a kind of cast iron, but low sulfur and phosphorus. The sulfur in iron sufficient carbon graphite. Low phosphorus improve the mechanical properties of cast iron.
Q:What's the difference between a cast iron and an iron iron pot?
A cast iron pot is what we usually call an iron pot. However, the difference between cast iron pot and pig iron is that the cast iron is the two processing, mostly processed into cast iron parts. Cast iron has excellent casting ability and can be made into complex parts. It has good machinability. In addition, the utility model has the advantages of good abrasion resistance, good shock resistance, low price, etc..
Q:The reaction principle of pig iron to steel
The carbon content in the pig iron is removed by smelting to reach the carbon content of the steel
Q:What about leakage of cast iron pipes?
The rubber plate is in correct position. Fasten the hoop with bolts and OK.This method is applied to the repair of non pressure pipes of various materials.You can also find a piece of iron or stainless steel (arc shape just can be wrapped on the water, and then dip the upper) special glue can also repair.
Q:What are the advantages and disadvantages of the contrast between cast iron and carbon?
Using a range of common steel: steel, steel hardness is very big, can be made of metal processing tool, crawler tractor and axle; manganese steel toughness is very strong, can make a spring sheet, coil; molybdenum steel high temperature resistant, crankshaft, aircraft can be especially hard tools; tungsten chromium steel with high hardness, strong toughness can do, machine tool and die; nickel chromium steel corrosion resistance, easy oxidation, also called stainless steel manufacturing, chemical production can be used in acid tower and medical equipment, daily utensils, etc..
Q:The pot is pig iron or wrought iron?
Because of its soft and lubricated graphite, casting pig iron has good cutting, wear resistance and casting properties. But its resistance to strength is not enough, it can not be forged, and can only be used to make a variety of castings, such as casting all kinds of machine tools, bed seats, iron pipes and so on. Ductile iron to carbon in the form of spherical graphite, which is far better than the mechanical properties of gray cast iron and close to steel, it has excellent casting, machining and wear resistance, has a certain flexibility, widely used in the manufacture of gear, crankshaft, piston and a variety of advanced casting machine parts. In addition, there are silicon, manganese, nickel or other elements particularly high in pig iron, called alloy pig iron, such as ferrosilicon, ferromanganese, etc., commonly used as steelmaking raw materials. The addition of certain alloy pig iron in steel-making can improve the performance of steel.
Q:What are the wall thickness and the outer diameter of flexible cast-iron drainage pipes?
According to the latest national standards, divided into A type, B type, W type, W1 type. Four specifications. Which one do you need? Their wall thickness requirements are different!
Q:What kind of iron does it have? What is iron? What is iron?
The difference between the categories of iron and steel of carbon / impurities (such as sulfur and phosphorus) mechanical properties of 2-4.3 cast iron machining hard brittle cast forged steel 0.03-2 can not be less hard and tough, elastic cast steel is can exercise at high temperature, the oxidizer (such as oxygen) the iron contained in the too much carbon and other harmful impurities (such as sulfur and phosphorus) removal, provisions of the scope of them reach the steel content.
