Iko kuverenga kwekuwedzerwa kwezvinhu zvakagadziridzwa zvesimbi yakanyungudutswa muchoto chekunyungudika induction:

gt=Gz(Xa-Xb)/Cd(kg)

gt-Kuwedzera huwandu hweC-inowedzera agent kana mamwe maalloys (kg)

Gz – Huremu hwesimbi yakanyungudutswa muchoto (kg)

Xa-chinangwa kukosha kwekuumbwa kwesimbi yakanyungudutswa (%)

Xb-Kuongorora kukosha kwekuumbwa kwesimbi yakanyungudutswa muchoto (%)

CC-inowedzera mumiririri kana zvimwe alloy zvemukati (%)

d-Absorption mwero wezvishandiso zvinoshandiswa (100% ndeye 1)

Simbi yakanyungudutswa C uye SI inodarika chinangwa chakaumbwa, wedzera zvimedu kuderedza C, SI kuverenga gt=Gz(Xb-Xa)/b

b-zviri mukati mechinhu chakagadziridzwa mune zvimedu

Iyo empirical data ndeye: wedzera 34kg simbi / t, kuderedza 0.1% C uye kuderedza 0.05% Si.
