Comprehensive Evaluation of Blast Casting Results Based on Unascertained Measurement and Intuitionistic Fuzzy Set

Table 1

The grading standards of quantitative indicators for evaluating blast casting results.

Level	Blast casting result	Powder factor/(kg·m^−3)	Limit vibration velocity/(cm·s^−1)	Effective casting rate	Looseness coefficient
I	Poor	≥0.78	≥2	≤0.30	≤1.15
II	General	0.75 ∼ 0.78	1.5 ∼ 2	0.30∼0.35	1.15∼1.20
III	Well	0.72 ∼ 0.75	1 ∼ 1.5	0.35∼0.4	1.20∼1.25
IV	Very well	≤0.72	≤1	≥0.4	≥1.25
