Cupola melting cast iron ductile iron and gray cast iron production technology components

The invention relates to a method of using iron castings production,[link widoczny dla zalogowanych], it is to overcome the loss of big iron of the hot metal,[link widoczny dla zalogowanych], the use rate of 87%, the cost of the problem of declining significantly, mainly in the technical features FeX28-1 with the additives together with the iron pressed into discus, by chemical treatment, smelting furnace hot metal in the sky can be obtained through the composition and stability necessary to deal with the national industry standard of hot metal, directly used to produce castings. Patent application number: 98811905 Public ID: 1,281,513 Patent Title: Cast iron inoculant gave birth to the production of agents and method of application: El Kaim Address: Oslo, Norway for the manufacture of the present invention relates to a sheet containing, dense or spherical graphite cast iron inoculant. The inoculant containing 40-80% (weight) of silicon ,0.5-10% (weight) of calcium, strontium and barium ,0-10% (weight) of cerium and lanthanum ,0-5% (weight) magnesium, less than 5% (weight) aluminum ,0-10% (weight) of manganese, titanium and zirconium, 0.5 to 10% (weight) showed one or several metal oxide form of oxygen, 0 .1-10% (weight) showed one or several forms of sulfur and metal sulfides margin as Fe. The invention also relates to methods of production of the inoculant patent number: 00112948 Public ID: 1,323,912 Patent Title: use of common high-phosphorus pig iron quality iron smelting high strength and toughness of the process the applicant: Hu Dezhi Address: London, Guiyang, Guizhou 550001 Pro Lane 65, No. 6 attached to the use of the invention is a high-phosphorus pig iron of ordinary quality high-strength ductile iron smelting process. Feature is that in the hot metal pouring from the ladle into the mold, in the hot metal surface scattering of people ferrosilicon powder. The invention process can take advantage of the ordinary high phosphorus pig iron smelting high strength and high toughness of ductile iron. Reduce production costs and expand the use of high phosphorus pig iron. Patent application number: 00123113 Public ID: 1,350,[link widoczny dla zalogowanych],069 Patent Title: High-strength alloy cast iron crankshaft and its production methods Applicant: XU Zhen Ran Address: 111000,[link widoczny dla zalogowanych], Liaoning Province, Liaoyang City, Liaoning, South Road, Dongxing Crankshaft Manufacturing Co.,[link widoczny dla zalogowanych], Ltd. and its high-strength alloy ductile iron crankshaft production methods, mainly by smelting cupola melting, the product of chemical elements in Fe-based, the other a small percentage% and trace elements were: 3.6 ~ 3.8C, 1.9 ~ 2.3Si, 0.3 ~ 0.5Mn, <O. 05P, <O. 035S, 0.03 ~ 0.05Mg ,0.02-0 .035 Re ,0.4-0 .6 Cu ,0.1-0 .2 Mo. Advantage of simple technology, low cost, product tension reached 900MPa, an extension of �� 4%, meet or exceed the level of similar foreign products, wear resistance, long service life. Patent application number: O1140111 open No.: 1,360,062 Patent Title: cupola melting cast iron ductile iron and gray cast iron production process application components: Zhang De Address: 461 500 Changge City Rail Road 78 (Coal Construction Company Hospital) ACE Limited vehicle spare parts production cupola melting cast iron ductile iron and gray iron casting process, is casting area. Of the present invention to solve the technical problems is to provide a cast iron using the cupola furnace cast iron direct human process. The main content of the process is to cast iron, coagulants, anti-oxidants, carbon dose, flux and water together and stir into the block directly after solidification were oven dried. Because cast iron cast iron block market price is the market price of 40-50%, so the main advantage of the present invention can reduce the cost per ton of castings 30-40%. The invention to the foundry industry has added a new bright spot. Patent application number: 99119251 Public ID: 1,286,313 Patent Title: Malleable annealing process and its equipment Applicant: INDUSTRIAL ENGINEERING Address: 030800 Shanxi Province, No. 49, Pei Ho South Taigu a malleable annealing process and its special equipment, the process by the gas , gas, dust and malleable annealing, whose special equipment for use in a simple t Queensland gas co gas furnace, the furnace mouth by the increase of coal, gasification agent population, gas exports, the upper and lower seal, manholes, hook gray , grate, fire-resistant layer, liner, shell, liquid level gauge and pressure gauge. The process is compared with the burning of coal, the use of self-produced gas as fuel for thermal annealing, the annealing furnace flue gas emissions to achieve emission standards set by the state level, the kiln temperature and even increased,
