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。A quantitative pretreatment scheme suitable to gc - ms analysis of bio - oil was proposed for the first time in china, and an extensive determination of the chemical composition of bio - oil fractions was performed by means of gc - ms coupling. these studies were crucial for the upgrading and utilization of bio - oil. using some novel designing method, which are suitable to biomass and pyrolysis characteristics, were applied in designing the fluid bed biomass flash pyrolysis system
