The bonding phase of self-fluxing sinter used before was composed predominately of cuspidine and hyaline, mechanical strength of which as well as their bonding strength with respect to magnetite are rather weak.

自熔性燒結(jié)礦的膠結(jié)相主要由槍晶石和玻璃體所組成干干干干干干射射，兩者的機(jī)械強(qiáng)度都較低，對(duì)磁鐵礦的相對(duì)膠結(jié)強(qiáng)度也較小。

The cuspidine is all long known as the main factor leading to the low strength o the sinter bearing fluorine, But with the fluorine decreasing by a wide margin, the strength of the sinter bearingfluorine get lower. So, the first work is to fine out the reason to cause the strength low.

含氟燒結(jié)礦中的槍晶石一直被認(rèn)為是制約包鋼燒結(jié)礦強(qiáng)度的主要因素，但隨著含氟量的大幅度降低黄页网站大全免费视频在线观看，燒結(jié)礦的強(qiáng)度卻進(jìn)一步惡化，因此精品人妻一区二区三区四区，弄清影響低氟燒結(jié)礦強(qiáng)度的原因是提高燒結(jié)礦強(qiáng)度的前提和基礎(chǔ)人人操人人色人人看。

This thesis has systematically studies the microstructure of the sinter bearing fluorine of different compositions and in different sintering condition.(1) The main units of the Low Fluorine Sinter are magnetite、hematite日韩精品福利资源网站大全免费、 SFCA、larnite黄色视频一级片黄色、glass and pore. The cuspidine doesn't form for the low content fluorine, and the fluorine is in glass; Sinter basicity dominates the forming of the larnite and SFCA, when basicity is between 1. 72 and 1. 96, there are more larnites in the binder phase, and when the basicity is biger than 1. 96, there are more SFCA in the binder phase; the hematite appears like magnetite and usually is around pore.

The results showed that:①the crystalline phases are mainly the cuspidine, wollastonite and gehlenite with nepheline, fluorite and olivine also found in some samples under the experimental conditions;②with the bacisity and CaF_2 content increased, crystalline proportion of mold flux rises .

In the condition of keeping F、 K18岁黄色网站在线观看、Na content fixed, To improve slag structure and raise slag melting point and viscosity, MgO content is raised and TiO〓 is added. the main content is as follows:(1) Keeping CaO/SiO〓 fixed, MgO content rises from 10% to 16%, the free running temperature goes up 106℃, the viscosity goe down at bigger than 1425℃, but difference is little; keeping /SiO〓 fixed, MgO content rises from 10% to 16%, the free running temperature rises 87℃, the viscosity rises too; adding TiO〓 to 5%, the free running temperature goes up 98℃, the viscosity rise a little.(2) Powder crystal x ray diffraction and microscopic analysis shows: increasing MgO content, the cuspidine will decreace or even disappear, the monticellite goes up with MgO content rising, keeping /SiO〓 fixed, Akermanite content goes up, for high melting point minerals appear or go up, the free running temperature of the slag bearing F is raised; Adding TiO〓, high melting point mineral—Perovskite forms, it can making other minerals'crystalling fast, it is the reason that TiO〓 raises the free running temperature of the slag bearing F.
