Abstract

FIELD: pig-iron heating in casting production. SUBSTANCE: gas cupola with idle refractory burden has burners output nozzles with total area of their holes cross-section equal to: 0.03 - 0.05 of shaft (Fsh) cross-section area with usage of cold blast (Tb = 20 C); 0.04 - 0.07 Fsh with Tb = 100 C; 0.05 - 0.09 Fsh with Tb = 200 C; 0.06 - 0.11 Fsh with Tb = 300 C; 0.07 - 0.13 Fsh with Tb = 400 C; 0.08 - 0.15 Fsh with Tb = 500 C. Cupola burners tunnel hydraulic diameter is equal to 1.15 - 1.4 of burner output nozzle hydraulic diameter. In the case during gas cupola operation on lining slag burners tunnels are made water cooling metallic, for example, of copper. EFFECT: stabilized pig iron heating in gas cupola with idle refractory burden during long duration and continuous process of heating.

Использование: область плавки чугуна в литейном производстве. Цель: стабилизация технологического процесса плавки чугуна в газовой вагранке с холостой огнеупорной калошей при длительном и непрерывном процессе плавки. Сущность изобретения: газовая вагранка с холостой огнеупорной калошей содержит выходные сопла горелок с суммарной площадью сечения их отверстий, равных: 0,03-0,05 площадки сечения шахты (Fш) при использовании холодного дутья (tв=20°С); 0,04-0,07 Fш при tв=100°С; 0,05-0,09 Fш при tв=200°С;0,06-0,11 Fш при tв=300°C; 0,07-0,13 Fш при tв=400°С; 0,08-0,15 Fш при tв=500°С, а гидравлический диаметр горелочного туннеля вагранки равен 1,15-1,45 гидравлического диаметра выходного сопла горелки. При работе газовой вагранки на гарнисаже горелочные туннели выполняются водоохлаждаемыми металлическими, например из меди. 2 з.п. ф-лы, 3 ил.Usage: cast iron smelting area in the foundry. Purpose: stabilization of the technological process of cast iron melting in a gas cupola with idle refractory galoshes during a long and continuous melting process. The inventive gas cupola with idle refractory galoshes contains outlet nozzles of the burners with a total cross-sectional area of their openings equal to: 0.03-0.05 of the mine cross-section area (F w ) when using cold blast (t in = 20 ° C); 0.04-0.07 F W at t in = 100 ° C; 0.05-0.09 F W at t in = 200 ° C; 0.06-0.11 F W at t in = 300 ° C; 0.07-0.13 F W at t in = 400 ° C; 0.08-0.15 F W at t in = 500 ° C, and the hydraulic diameter of the burner tunnel of the cupola is 1.15-1.45 of the hydraulic diameter of the outlet nozzle of the burner. When the gas cupola is working on the skull, the burner tunnels are made of water-cooled metal, for example, copper. 2 s.p. f-ly, 3 ill.
