Question 2: What industry needs forgings A forging is an object in which metal is pressurized to mold a required shape or suitable compression force through plastic deformation. This force is typically achieved through the use of a hammer or pressure. The casting process builds a delicate granular structure and improves the physical properties of the metal. In the real world use of parts, a proper design allows the particles to flow in the direction of the main pressure. The forgings need to be consistent from piece to piece, free of any porosity, excess space, inclusions or other imperfections. This method produces elements that have a high ratio of strength to weight. These components are commonly used in aircraft structures.
The advantages of forgings are extendable length, shrinkable cross section; shrinkable length, extendable cross section; changeable length, changeable cross section. The types of forgings are free forging/hand forging, hot die forging/precision forging, top forging, roll forging and die forging.
Therefore, forgings are generally used in critical components that require high strength and toughness of the product, this critical characteristic of forgings is cast plastic parts and other process products can not be replaced, such as engine crankshafts and connecting rods, they work at high intensity under shock loads.
Forging - types:
Aircraft forgings, diesel forgings, marine forgings, weapons forgings, petrochemical forgings, mining forgings, nuclear forgings, thermal power forgings, hydropower forgings.
It is really a wide variety.
Question 3: Forgings and powder metallurgy products manufacturing industry belongs to which machinery industry, or other industries? The same belongs to the metallurgical industry, if subdivided, forgings can be categorized into the metallurgical industry under the ferrous metallurgy engineering, powder metallurgy engineering is also a branch of the metallurgical industry.
Question 4: What industry does steel casting belong to? What industry does steel fabrication belong to? ----- The rough casting of the machine shop belongs to the machinery industry;
----- The steel molding casting (continuous casting machine) of the steel plant belongs to the metallurgical industry.
Question 5: What are the standards for forgings 20 #, 16Mn, 15CrMo is the material of forgings, JB4726 is the acceptance standard. 20G, 15CrMoG is a material in the steel. G is the first letter of "pot" in boiler plate: G. Implementation standard: GB713-2008. Scope of application: thickness 6mm-150mm steel plate Therefore, there is no 20G, 15CrMoG material for forgings. And there is no such steel grade as 20G in the new grade! General Administration of Quality Supervision, Inspection and Quarantine Division (Bureau) letter Qiuqi special letter [2008] No. 64 on the GB713-2008 and GB/T9222-2008 implementation of the transitional period arrangements for the notice Provinces, autonomous regions and municipalities directly under the Central Bureau of Quality and Technical Supervision, the relevant units: "boiler pressure vessel steel plate" (GB713-2008) and "water tube boiler compression element strength calculations" (GB/T9222-2008). GB/T9222-2008) were implemented on September 1, 2008 and July 1, 2008, respectively. In order to solve the old and new standards in the process of conversion of the actual difficulties of enterprises to ensure the smooth implementation of the above standards, after consultation with the relevant Standardization Technical Committee, put forward the following views, please follow the implementation of the units.

(B) boiler pressure vessel manufacturing unit in September 1, 2008 to August 31, 2009 period can be used at the same time GB713-1997, GB6654-1996 (including revision orders) and GB713-2008 materials for the manufacture of boiler pressure vessels. September 1, 2009 shall not be used GB713-1997 and GB6654-1996 (including revision orders). 1996 (including amendments) of the material. (C) selection of GB713-2008 in the 14Cr1MoR and 12Cr2Mo1R material manufacturing boiler pressure vessel, GB713-2008 implementation of the welder's test and welding process evaluation before the implementation of its ability to cover the scope of the still valid; the selection of GB713-2008 other materials for the manufacture of boiler pressure vessels, according to GB713-1997 and GB6654-1996 (with modifications). GB6654-1996 (including amendments) listed in the number of welders examined and welding process evaluation, in the scope of its ability to cover the corresponding new sign still applies to GB713-2008 Appendix A, the relevant units should be completed by August 31, 2009 welding process evaluation and other relevant documents using the new material signifies the conversion of the work. (D) selection of GB713-2008 in the material design and manufacture of boiler pressure vessels, in the same specifications and use of the state, the relevant design parameters and manufacturing inspection requirements should be based on GB713-2008 Appendix A corresponding to the old grade of the relevant provisions, or else should be applied to the National Boiler and Pressure Vessel Standardization Technical Committee for special technical review. (E) for the boiler pressure vessel has obtained a license for steel plate manufacturing enterprises, according to the license allows the production of new grades of steel. Enterprises should apply for a new license as soon as possible, boiler and pressure vessel steel manufacturing identification and evaluation agencies should be completed before December 31, 2008, the necessary review and confirmation of the work. Second, "water tube boiler pressure element strength calculation" (GB/T9222-2008) implementation of the transitional arrangements (a) boiler design and manufacturing units in July 1, 2008 to December 31, 2008 period can be used at the same time GB/T9222 of the 2008 version and 1988 version of the boiler strength calculations. January 1, 2009 shall not be used from 1988 version of the calculations) Design of boilers, boiler design documents previously identified by the use of GB/T9222-1988 calculations continue to be valid, but should be manufactured in accordance with GB713-2008 old and new steel grade correspondence to choose a new grade of steel. (B) since July 1, 2009, the boiler design documents identification agency shall no longer use GB/T9222-1988 boiler drawings for identification. (C) in-use boilers for strength calibration, can be calculated according to the original calculation standards. (D) boiler designers and boiler design ...... >>
