STEEL QUENCHING PROCESS AS HYPERBOLIC HEAT EQUATION FOR CYLINDER

* University of Latvia, Faculty of Physics and Mathematics, Zellu str. 8, Riga, LV 1002, Latvia ** Institute of Mathematics and Computer Sciences, Raina bulv. 29, Riga, LV1459, Latvia Intensive quenching method in water in opposition to oil is offered last three decades [1]. This process is quite complicated. The group of mathematicians of Latvia is involved in this research since year 2005. The most important are mathematical models of samples of complicated shapes.
