Abstract
Inventia se refera la un procedeu de racire a unei forme de turnare, cum ar fi de exemplu o lingotiera în care se toarna metale si aliaje feroase sau neferoase. Procedeul conform inventiei consta în aceea ca, cupa turnarea metalului sau aliajului în forma un agent de racire format din azot lichid este circulat într-o incinta în care este închisa forma de turnare. Azotul lichid aflat la o temperatura de -190 degree C si o presiune de 2 at, cu un debit de 120.....140 1/min se volatilizeaza instantaneu în spatiul închis în care este plasata forma obtinîndu-se astfel o racire rapida a materialului pe întreaga înaltime a formei în timpul racirii, azotul volatilizat fiind evacuat liber din spatiul amintit. Dupa solidificare , circulatia de azot lichid este întrerupta. Procedeul cinform inventiei prezinta urmatoarele avantaje: îmbunatateste segregatia zonala si distributia gazelor în masa metalica a lingourilor si pieselor turnate ceea ce conduce la obtinerea unei omogenitati chimice si structurale mai bune; scurteaza timpul de solidificare, ceea ce determina o economisire de energie si material metalic.The invention relates to a process for cooling a casting mold, such as for example an ingot mold in which ferrous metals or non-ferrous alloys are poured. The process according to the invention consists in the fact that the casting of the metal or alloy in the form of a liquid cooling agent is circulated in an enclosure in which the mold is closed. The liquid nitrogen at -190 ° C and a pressure of 2 atm with a flow rate of 120 ... 140 1 / min is instantly volatilized in the enclosed space in which the mold is placed, thus obtaining a rapid cooling of the material over the entire height of the mold during cooling, the volatilized nitrogen being evacuated freely from the said space. After solidification, the liquid nitrogen flow is interrupted. The process according to the invention has the following advantages: it improves the zonal segregation and gas distribution in the metallic mass of the ingots and castings, which leads to a better chemical and structural homogeneity; shortens the solidification time, which results in energy saving and metallic material.
