FIELD: metallurgy. ^ SUBSTANCE: invention refers to foundry engineering. The installation, made in form of a vertically assembled collector, consists of a tube for supply of water, an air supply tube, supplying branches attached onto and connecting both tubes, and of mixing branches for supply of air-water mixture into nozzles arranged on the ends of the branches. Throttle heads are installed in supplying branches. The lower head has the ratio of length to internal diametre 15Ç40, while the ratio of lengths of heads to their internal diametres from the head to head upward decreases at 1.6Ç8.2. ^ EFFECT: uniform cooling of continuous cast billet. ^ 1 dwg, 3 tbl |
