FIELD: manufacture of coupled-link structures such as chains, namely anchor chains, chains of hoisting equipment, suspended chains of chain curtains of cement furnaces and of other modern machines and mechanisms.
SUBSTANCE: method comprises steps of making gasifiable patterns of main and intermediate links of chain; assembling made patterns to pattern unit. Said unit is in the form of reverse riser around which gasifiable patterns of main and intermediate links of chain are mounted vertically and fan-like with use of flow gates. Patterns of main and intermediate links are mounted along the same axis normally one to other. Central gate is mounted on base of reverse riser. Gasifiable patterns with gates and gating with central gate are placed in flask; then pouring gate is placed to flask for simultaneously casting all links of chain.
EFFECT: improved quality of cast chain, lowered labor consumption for making it.
