Computer simulation analysis of the performance of the hardening agent
Set the coordinate r at the remarkable San structure. Traditional m map, the amount of information to be classified as dynamic differential equations form model: J - 1uy-jkjyj (1 yJ) [:] (4), YJ (j = l,

Ferrite, pearlite and bainite non-isothermal transformation, described by the solution of differential equations (4),

Estimate for the martensite volume of a new formula to replace the 克斯蒂内恩 (Koisti ~ en) and other well-known formula. 3 Results of the selection of six quenching Jing. The corresponding heat transfer coefficient as a function of surface temperature is given in Figure 1. For the quantitative characterization of the heat transfer coefficient,
sac louis vuitton, we calculate the corresponding temperature TI and the most too hot transfer coefficient in the temperature range of 300.4 thousand ℃, 400 ~ 500 ℃, 500 ~ 600 ℃, 600 ~ 700 ℃ and 700 ~ 800 ° C, each is satisfied that the heat the average value of the transfer coefficient, H ·, HnH ·, and H,. These data are listed in Table 1. Heat transfer function from six pre-selected to proceed. Computer simulation,
sac longchamp, we calculate the cooling and transition process. To this end, choose 10 ~ 50mm different diameter cylindrical specimens. The steel used in the simulations for ordinary carbon tangled steel and low-magic. Denoted by A and B, their components are listed in Table 2,

Quantitative expression of the selected quenching Jing hardened performance, we calculated the relationship between the different diameter steel holding the horse and rod diameter is shown in Figure 2. The amount of the Golgi. Calculated the amount of martensite quenching the rod at the center of 40000ooo photo 20000 rumor the 10000 the built Ol00007500 scoundrel 50002500OO25050071; O temperature,

The amount of martensite in the steel ° C temperature, ℃ temperature, ℃ prince Yu analysis of six selected quenching the Jing heat transfer coefficient and disheartened relations) in accordance with Figure 2, the cooling performance of the hardening agent can be used to meter temperature,

Another advantage of the proposed method: quenching capacity of the cooling medium may also be considering the steel composition and workpiece 6l · p.

The analysis of Figure 2, can be observed in the composition of the materials significantly affect the hardening of steel. Spit fire on the basis of the predicted martensite volume of six kinds of the study agent, on the order of the two steel is not the same. Can see that the order of actinium A, as follows,
