Oct 17, 2018 In addition, free lime has shown a harmful effect on the stability, physical properties and hardening of cement when exceeding a certain content . For example, with the loss of ignition within 25 07 at the temperature of 850 C after passing 1 5 h, MOS cement could not be formed because the reaction was too intense and hardening took place ...
Jan 31, 2016 The process of cryogenically treating a metal part involves very slowly cooling the metal using gaseous liquid nitrogen. The slow cooling process from ambient to cryogenic temperatures is important in avoiding thermal stress. The metal part is then held at a temperature of around 310 F. 190 C. for 20 to 24 hours before heat tempering ...
