The design for the cooling zone of a roller hearth kiln is inappropriate in some aspects.

The authors first put forward a controllable quenching theory The theory is that the quenching intensity of quenching medium can be modified by means of quantifying control And three control factors have been given in the water quenching process of quantifying control The high chromium cast iron has been taken for example to use the technology which succeeds in practice productio

Effect of subsection cooling process on banded structure of C-Mn plate has been studied by industrial tests.

This article introduces the principle of subsection cooling control of rolling oil,it also discusses the controlling method of roller thermal crown and meaning of the parameter controllin

During controlled cooling,not only start cooling temperature affects mechanical properties of test steel,but also subsection cooling mode can increase mechanical properties of test steel.

The chill-fractionted extraction technology soy oil with isopropyl alcohol(IPA)was studied and the energy consumtions were compared with the tradition methods so as to decide concentrations of isopropyl alcohol with miscellas and temperature effects on upper and lower phase.
