ASTM 410 Steel Forging Shaft for Big Ship Vessel
1. Process: ingot → heat → forging → heat treatment(normalizing+tempering) → inspection  → rough machining → UT → 2nd heat treatment → finishing machining → inspection . 2. Heat treatment: Normalized / Annealed / Quenched / tempered 3. Delivery condition: Hot forged +Rough machined (black surface after Q/T)+ Turned (optional) 4. Inspection Equipments: Metallurgical analysis, Tensile strength tester, Hardness  tester, Altimeter, Scale Micrometer, pressure tester, etc. 1. Process: ingot → heat → forging → heat treatment(normalizing+tempering) → inspection  → rough machining → UT → 2nd heat treatment → finishing machining → inspection . 2. Heat treatment: Normalized / Annealed / Quenched / tempered 3. Delivery condition: Hot forged +Rough machined (black surface after Q/T)+ Turned (optional) 4. Inspection Equipments: Metallurgical analysis, Tensile strength tester, Hardness  tester, Altimeter, Scale Micrometer, pressure tester, etc. Rail transportation of inclined shafts is an integral part of mine transportation and an important link in safe production of coal mines.According to the requirements of the coal mine safety regulations, the safety measures of "one slope and three gears" must be set up in the transportation of inclined shafts, namely the car barrier, the automatic anti-sports car device and the vehicle blocking device.Over the decades, the number of casualties caused by accidents involving sports cars in mines has become a "stumbling block" for the development of coal production.Stopper is installed at the bottom of the well head to stop the car because of out of control and decline of machinery, divided into two kinds, often and often closed can effectively stop car fall, avoid the occurrence of major accidents Pneumatic Mine Car Arrested Stopper Pneumatic Mine Car Arrested Stopper,Wheel Stopper Track Arrester,Cast-Iron Mine Car Arrester,Underground Mine Car Arrester Jining Dongda Electromechanical Co.,Ltd. , http://www.coal-mine-equipment.com
Name :Â Â Hydraulic Turbine Shaft
5. Material: carbon steel or alloy steel
The heavy forging: forged ring, shaft, roller, flange, or gear is widely used for various industries
