查询词典 calcia

So, using magnesia and calcia crucible in VIF respectively, the experiments on deep deoxidation by carbon and the phenomenon of oxygen contamination from crucible materials in the molten steel under some temperature and vacuity and oxygen content of the molten steel were made and it were found that properly low melting temperature and vacuity helped to lighten and even avoid oxygen contamination from crucible material and the refining effect of final oxygen content of 5×10-4% in the molten steel was achieved using calcia crucible with better resistance to thermal shock under higher vacuity.

为此，分别采用MgO炉衬与CaO炉衬，在真空感应炉中对钢液用碳进行深脱氧和炉衬供氧现象实验研究，发现：(1)在适当低的熔炼温度和真空度下，可以减轻甚至避免炉衬热分解向钢液供氧；(2)采用热稳定性优越的CaO炉衬，在较高的真空度下可达到钢液最终全氧含量低于5×10-4%的精炼效果。

Under high temperature and vacuum, calcia crucible has better resistance to thermal chock and better chemical denudation than magnesia crucible.

在高温和真空下，CaO质炉衬的热稳定性和化学稳定性远比MgO质炉衬好。

The effect of electrocast zirconia and monocline zirconia and two types of binders(anhydrous and un-hydroxyl resin and liquid paraffin)on the sintering of fired magnesia-calcia brick are investigated.

研究了电熔氧化锆、单斜氧化锆和两种结合剂(无水无羟基树脂和液体石蜡)对烧成镁钙砖烧结性能的影响。

The results indicate that the effect of anhydrous and un-hydroxyl resin is better than liquid paraffin and each of electrocast zirconia and monocline zirconia can promote sintering of magnesia-calcia brick,and the effect of monocline zirconia is better than that of electracast zirconia.

结果表明：作结合剂用时无水无羟基树脂效果好于液体石蜡；作为添加剂时电熔氧化锆和单斜氧化锆均能显著促进镁钙砖的烧结，其中单斜氧化锆的效果好于电熔氧化锆。

The experiment and application of magnesia calcia-carbon fireproof bricks in 25gLF refinement ladle is introduced.

介绍了镁钙碳砖在25tLF精炼炉钢包上的试验及使用情况。
