Temper by dipping in water of influence rolled steel appears sexual element
The main factor that affects rolled steel temper by dipping in water to appear a gender has; The chemical composition of rolled steel,
Quench heat of the character of temperature, cooling medium, cooling means method, spare parts
Shape size and heat means.
(The chemical class status of I) rolled steel affects temper by dipping in water to appear the factor with the mainest sex
One. Always cause in steel " C " the curve is right move or left moving alloying element,
Comfortable to temper by dipping in water sex is having huge effect. Make " C " the curve is right moving element will raise steel
temper by dipping in water appears a gender; Make " C " the curve is left moving element shows the oil that reduces steel the gender. Be like
45 steel and 40Cr steel, its contain carbon the amount is similar, but, as a result of former do not contain chromic element,
The latter element that contain chromium makes an appointment with 1 % , be in equal below heat treatment condition, their temper by dipping in water is appeared
The gender differs apparently, 45 steel can temper by dipping in water is far 3. 5, 9. 5 millimeter, and 40Cr steel but temper by dipping in water
Appear 25-32 millimeter.
(The cooling character of medium of refrigeration of 2) heat treatment and cooling rate, to steel
Temper by dipping in water appears a gender to also have very big effect. Cooling rate is rapid, temper by dipping in water appears a gender to rise, cooling
Speed but, temper by dipping in water appears a gender to be reduced. 45 steel cool in water and be for example in oil cold
However, its temper by dipping in water appears a gender to differ, when cooling in water, but temper by dipping in water appears 11 one 20 millimeter,
When cooling in oil, but temper by dipping in water is appeared 3. 5, 9. 5 millimeter.
(The shape size of 3) spare parts, heat temperature, cooling means, be in not
The temper by dipping in water that there is steel on degree together appears a gender. Shape size is small, heat temperature is high,
Successive refrigeration can raise temper by dipping in water to appear a gender on certain level; And shape size is large,
Heat temperature is isothermal and low, cooling wait to be able to make temper by dipping in water appears a gender to drop however.
(The means that 4) heats also can affect temper by dipping in water to appear a gender, in be being operated actually, this is
Very important, we often ignore this easily. Because heat,means differs,
Of generation heat the effect is distinct also. Compare saline bath furnace to arise with box type electric stove for example
Phenomenon of oxidation, decarbonization is serious, can reduce temper by dipping in water to appear a gender.
