在原有5 t(实际5.15 t)八角锭的基础上
将锭身高度由1505 mm增加至1840mm
锥度由4.56%降至3.64%
由原外置帽口改为内置帽口
钢水帽口率由15.15%减少到9.81%
新设计的6 t(实际5.85 t)八角锭模生产18CrNiMo7-6
D2和30Cr13钢Φ210~300 mm锻材的结果表明
6 t锭平均成材率为86.47%
较5 t锭平均成材率79.71%提高了约7个百分点。
Based on the original 5 t (real 5. 15 t) octagonal ingot mould
with increasing the height of mould from original 1505 mm to 1840 mm
decreasing the taper in the mold walls from 4. 56% to 3. 64%
modifying the hot top location from outside type to inside type and decreasing the ratio of liquid steel in hot top from 15. 15% to 9. 81%
the results of production of Φ210 ~ 300 mm forged products of steel 18CrNiMo7-6
D2 and 30Cr13 by new design 6 t ( real 5. 85 t) ingot mould show that the average yield of 6 t ingot is 86. 47%
as compared with the average yield 79. 71% of 5 t ingot
it increases the yield of products by about 7 point of percentage.
