The microstructure and mechanical properties of metal can be improved after forging. Casting organization after forging method of thermal deformation due to metal deformation and recrystallization, make original bulky dendrite and columnar grain to grain is fine and uniform axial recrystallization organization, make the ingot in the original segregation, porosity, porosity, slag compaction and welded, such as its organization become more closely, plasticity and mechanical properties of the metal.
Tong Xin Precision Forging Co., Ltd. can supply forgings of the following categories:
Aircraft forgings
By weight, about 85% of the plane's components are forgings. The turbine disc of aircraft engine, rear journal (hollow shaft), blade, wing SPAR, fuselage rib plate, wheel bracket, inner and outer cylinder of landing gear are all important forgings related to aircraft safety.
Diesel forgings
Diesel engine is a kind of power machinery, it is often used as an engine. Taking large diesel engine as an example, the forgings used include cylinder cover, spindle journal, crankshaft end flange output end shaft, connecting rod, piston rod, piston head, crosshead pin shaft, crankshaft transmission gear, gear ring, intermediate gear and dye oil pump body, etc.
Marine forgings
Marine forgings are divided into three categories, main engine forgings, shafting forgings and rudder forgings. Main engine forgings are the same as diesel engine forgings. Shafting forgings have thrust shaft, intermediate shaft stern shaft and so on. Rudder system forgings rudder, rudder post, rudder pin, etc.
Weapon forgings
Forgings play an important role in weapon industry. By weight, 60% of tanks are forgings. The barrel, muzzle brake and tail of artillery, ribbed barrel and three-ribbed bayonet of infantry weapons, rocket and submarine depth charge launchers and fixing mounts, stainless steel body of nuclear submarine high pressure cooler, shells, cartridges, etc., are all forged products. In addition to steel forgings, weapons are made of other materials.
Petrochemical forgings
Forgings are widely used in petrochemical equipment. For example, manholes and flanges of spherical storage tanks, various tubeplates required by heat exchangers, whole forged cylinders (pressure vessels) of butt welded flange catalytic cracking reactors, cylinders used in hydrogenation reactors, and top, bottom and sealing heads required by fertilizer equipment are all forgings.
Nuclear power forgings
Nuclear power is divided into pressurized water reactors and boiling water reactors. The main heavy forgings in nuclear power plant can be divided into two categories: pressure shell and internal components.
