中文拼音 [gāotàntiěshuǐ]
高碳鐵水
英文
high carbon hot metal-
On the base of the analysis on the advanced technology of hard ferrite in foreign country, the main procedures of preparing hard ferrite pre - sintering material are determined as follows : first, the ferrite oxides coming from the main cold rolling line and strontium carbonate are conveyed to storage tank by gas power and weighed automatically according to the demands of constituent composition. and then they are mixed and grinded by using method of wet treatment. finally the mixtures is transported to the devices of storage by transporting pump
在分析國外先進的永磁鐵氧體生產工藝的基礎上，確定了生產高檔永磁鐵氧體預燒料的主要過程：首先，利用攀鋼冷軋鐵紅為主要原料，將氧化鐵紅及碳酸鍶採用氣力輸送至貯料料倉，經自動稱量裝置，按工藝配方稱量後分別由氧化鐵紅及碳酸鍶發送罐氣力輸送進入預混攪拌筒加水攪拌，然後再送入混磨機濕法混磨；最後，混合物經輸送泵輸送至料漿存儲裝置，經定量進料泵定量輸送至回轉窯進行濕法預燒，預燒料經緩冷至室溫后，再球磨。Experimental study on decarbonisation of hot metal from kungang bf
昆鋼高爐鐵水脫碳實驗研究Sintering speed increased greatly with the help of great quantity of heat of the molten iron, the great quantity of heat sent out from the carbonizing reaction and a little quantity of liquid, this sintering type is an instantaneous sintering, the sintering compacting can carry completely in a few minutes, the degree of sintering compacting is very high. ( 6 ) the vc - fe surface composite has high rigidity, it ' s rigidity exceeds 60hrc, under condition of dry sliding friction and overloading
鑄造燒結時，過熱鐵水的巨大熱流密度沖擊、粉料壓坯中的碳化反應的放熱以及壓坯中少量液相的產生使壓坯的燒結速度大大提高，此時屬瞬間液相燒結，在十幾分鐘內燒結過程即可完成，可達到很高的緻密化程度。 （ 6 ）鑄態下vc一fe表面復合材料具有很高的硬度，其鑄態硬度） 60hrc 。For edible chrysanthemum, the results show that the flower of edible chrysanthemum is comparable to or higher than the five common vegetables in the content of the four principle nutrients ( protein, fat, ash content and carbohydrate content )
食用菊花的碳水化合物、蛋白質、脂肪、灰分的含量較常見蔬菜高或相當，氨基酸種類齊全，人體所必需的微量元素鐵、鋅、硒和維生素b1 、 b2的含量遠高於一般蔬菜。Spurred by strong state support, chinese companies have become the dominant makers of steel, coke, aluminum, cement, chemicals, leather, paper and other goods that faced high costs, including tougher environmental rules, in other parts of the world
因為有政府的大力支持，中國目前是世界上最大的鋼鐵，焦碳，鋁製品，水泥，化工，皮革，造紙等產品的生產基地，這些行業在其它國家無一不被認為是高成本，甚至對環境造成嚴重污染。The speed became fast at the temperature 1050. the reaction could carry completely when billets was kept in vacuum tube for 3 hours " at 1050 temperature, under the striking of great quantity of heat when the molten iron poured into the mold, the reaction was blazed rapidly and continued at a high speed. the diffusible speed of v and c was very fast because the billet was heated over 1300 in a moment, so the reaction ca n complete in a few minutes
（ 5 ）碳化反應v + c vc在900左右開始發生，此時是固相反應，反應速度較慢，反應不能進行完全，隨溫度升高，該碳化反應的速度加快，在1050保溫3小時可以進行完全，在鑄造燒結時在過熱鐵水的巨大熱流密度沖擊下， v + c vc立即被激發，並以很快的速度進行，由於坯塊被加熱到1300以上，此時c和v擴散速度很快，因此鑄造澆注后的幾四川大學碩士學位論文分鐘內反應可以進行完全。分享友人
