Effect of filling ratio and melting speed on the quality of ESR ingot of H13 hot-work die steel was studied. 研究了填充比與熔速對H13熱作模具鋼電渣質(zhì)量的影響。
In this paper, the DSC analysis is used to study the MPDA/DDM mixture, the lowest co- melting temperature and ratio are given; 本文應(yīng)用示差掃描量熱（DSC）法對間苯二胺（MPDA）和二氨基二苯甲烷（DDM）混郃物進行了等速陞溫熔融研究，得出了它們的最低共熔配比；
The slag column method and the melting ratio method were used to show the relationship between the carbon materials added and the melting rate of fluxes. 採用渣柱法和熔化率法兩種不同的測試方式進行了碳質(zhì)材料與保護渣熔化速度的關(guān)系研究。
