模具重量计算（Die weight calculation） The theoretical weight of 1. steel is 4 Q (E; G) C; a* Z0] `2, G6, R8, x#, u, d, a, R (O#, M, G3, P:, M, K, n) The theoretical weight of the steel is calculated by the nominal size of the steel and the density (formerly called the specific weight). The weight is called the theoretical weight. This is directly related to the length, size, sectional area and allowable deviation of the size of the steel. Because of the allowable deviation of the steel in the manufacturing process, the theoretical weight calculated by the formula is different from the actual weight, so it is only used as a reference in the estimation.
