普通热处理分为退火、正火、淬火和回火。
The types of ordinary heat treatment of steel are annealing, normalizing, quenching and tempering.

退火是将钢加热到预定温度，保温一定时间后缓慢冷却（通常随炉冷却），获得接近于平衡组织的热处理工艺。
Annealing is a treatment process of steel by heating to a predetermined temperature, holding for a certain time, and then cooling slowly to room temperature (normally together with the furnace), so that the equilibrium microstructure is obtained.

正火是将钢加热到亚共析钢或共析和过共析钢以上30-50℃，保温适当时间后在静止空气中冷却的热处理工艺。
Normalizing is a treatment process of steel by heating to 30-50℃ above temperature level of hypoeutectoid steel or eutectoid and hyper-eutectoid steel, holding for a suitable time and then cooling in still air.

淬火是将钢加热到亚共析钢或AC1以上30-50℃，经过保温后在冷却介质中迅速冷却的热处理工艺。
Quenching is a treatment process of steel by heating to 30-50℃ above temperature level of hypoeutectoid steel or Ac1 (正确写法是用小写c), it is then rapidly cooled in cooling agent after holding. (据我了解，淬火似乎不需要保温)。

回火是把经过淬火的零件重新加热到低于AC1的某一温度，适当保温后，冷却到室温的热处理工艺。
Tempering is a treatment process of steel by reheating the quenched components to a temperature below Ac1, after appropriate holding time, and then cooling to room temperature.

回答2：

the ordinary thermal treatments are divided as annealing, normalizing, quenching and tempering.

Annealing is the thermal process to achieve updating equilibrium microstructure , which is heating the steel upto a predetermined temperature, holding for a certain time and cooling slowly.

normalizing is the thermal process which is heating the steel as hypoeutectoid steel or saturated steel, and hypereutectoid steel up to 30-50℃, holding for a certain time and cooling naturally.;

quenching is the process which is heating the steel as hypoeutectoid steel or AC1 up to 30-50℃, and cooling quickly in the coolant after heat insulation.

tempering is the process which is heating the spare parts being quenched up to a certain temperature under the temperature for AC1, holding properly and then cooling down to room temperature .
