If oil quenching, understand that you need to have a large volume of oil so that the steel can't heat the whole volume of oil to the point where it reaches ignition temps. One of the forged in fire
- Can intermittent water spray quenching be used for forged grinding balls?
- The aim of the present work was to study the possibility of the use of intermittent water spray quenching combined with air cooling for fabrication of forged grinding balls from steel 70SiMnCr with a “composite” structure of martensite on the surface and martensite + bainite in the core and to assess their wear resistance.
- Does temperature and holding time of isothermal quenching affect microstructure of GCR15 steel?
- In order to compare the effects of temperature and holding time of isothermal quenching on the microstructure of GCr15 steel, the following heat treatment process is used. First, the sample is heated to 860 °C with JHF-27 heat treatment furnace and held for 30 min, and then quenched into salt bath at 200 °C and 230 °C for isothermal quenching.
- How to select heat treatment quenching oil?
- Selection method of heat treatment quenching oil The principle of selecting quenching oil in the heat treatment quenching process has been discussed: the oil must have a cooling performance that reaches the required hardness, with a fast cooling speed and no cracks.
- What is the difference between isothermal quenching and 230 °C?
- Compared to the isothermal quenching at 200 °C, the content of bainites in the steel is higher after isothermal quenching at 230 °C for the same time, that is to say, the time required to reach the same bainite content is relatively shorter at 230 °C.
- Does isothermal quenching affect bainite transformation in GCR15 steel?
- Through hardness measurement and microstructure observation, the effect of isothermal quenching on the bainite transformation, the size and area fraction of carbides in GCr15 steel was studied.
- How to forge grinding balls with water spray cooling?
- A process of forging grinding balls with the use of water spray cooling is suggested, which ensures bainite transformation under isothermal conditions and formation of the specified structure. The W70A45W20 process, implemented at 200°C for 4.5 h, yields balls with a final volume hardness of 56 HRC and a toughness of 73 J.
