Heat Treatment of S.G. Irons | Cast Irons | Metallurgy

Surface,-,Hardening,: S.G. iron responds well to the common ,surface,-,hardening, methods; by flame, induction or even laser. As the heating-time is short in these methods, complete pearlitic matrix is preferred as it responds instantly with little holding time at the austenitising temperature, normally between 845 to 900°C in order to harden- fully the thin ,surface, layer.

Treatment of Effluent Waters from Vegetable Oil Refining

Vegetable ,oil, refineries generate a high BOD5 loading along with a high fat loading, which makes ,treatment, difficult. Original loadings with only ,surface, skimming as ,treatment, generated 0.0135 kg BOD5 per kg ,oil, processed. After the grant period, the load was 0.0019 kg per kg processed for a reduction of 86%.

• At such high temperatures, decarburisation at the ,surface, may take place in the presence of oxygen • Decarburisation will result in decrease in carbon content in the martensite formed at the ,surface, • It will give rise to low hardness in the ,surface, after ,hardening, • Hence protective atmospheres may be used in heat ,treatment, to avoid oxidation or decarburisation • Innert gases may ...
