Briquetting machine pressure roller casting is my factory long products, net weight 445 kilograms. Gross weight 560 kg. Material QT50-5, the chemical composition and physical properties after heat treatment, such as the table for the dry mold, horizontal shape and pouring, pouring nozzle with a semi-open casting system with a damper, the gate area ratio as follows: F: F horizontal resistance: F horizontal: F straight = 1: 0.058: 0.2: 0.25. In the outer wall of the mold, 12 pieces of 280 × 90 × 70 single-sided arc cooling iron are set on the outer wall of the mold, and 6 pieces of chilled iron in the plane of 150/110 × 90 × 60 arc in the plane of the inner wall sand core are arranged. Other structural dimensions and process schemes Layout as shown.
