    The viscosity of slags containing Al_2O_3 15%, MgO 10%, TiO_2 15—35% and with a CaO/SiO_2 ratio of 0.6—1.6 has been measured with an oscillating viscosimeter. Experimental results indicate that the viscosity of titanoslags is very low provided they are not previously subjected to a strong reducing action. The melting point of the slags depends on the CaO/SiO_2 ratio and TiO_2 content. Under a strong reducing condition, however, the TiO_2 can be reduced to lower oxides and even titanium carbide,...

    The viscosity of slags containing Al_2O_3 15%, MgO 10%, TiO_2 15—35% and with a CaO/SiO_2 ratio of 0.6—1.6 has been measured with an oscillating viscosimeter. Experimental results indicate that the viscosity of titanoslags is very low provided they are not previously subjected to a strong reducing action. The melting point of the slags depends on the CaO/SiO_2 ratio and TiO_2 content. Under a strong reducing condition, however, the TiO_2 can be reduced to lower oxides and even titanium carbide, and the slags become, quite viscous. An increase of temperature and decrease of CaO/SiO_2 ratio increase the rate of thickening. Experimental evidence verifies the presence of finelydispersed titanium carbide, which is the primary cause for thickening. The addition of an oxidizing agent or blowing of slightly oxidizing gases such as CO+CO_2 through the slag can prevent the latter from becoming viscous. These measures might prove helpful in blast-furnace smelting of titanium-containing iron ores.The main mineral constituents of the titanoslgs under investigation are perovskite, anosovite, baikovite and titaniferrous augite. Their relative amount depends upon the chemical composition of the slags and the degree of reduction.

    In order to elucidate the conditions for the black layer formation in the recently reclaimed saline soils under rice cultivation,a series of laboratory experiments were carried out using soil columns in glass tubes percolated by dilute Na2SO4 solution.The results demonstrated that the black layer was easily formed at higher temperatures as long as there were sufficient amount of sulfate and energy materials in the soil.The presence of Na2SO4 in the irrigation water even as low as 0.05% in concentration hastened up the process markedly,the black layers in soil column experiments as well as in the fields were characterized by strong reducing conditions(Eh-100 to-200mv)and high contents of Fe2+ and S2-ions.The everage molar ratio of Fe2+ to S2-in the black layer was found to be in approximate correspondence to the FeS formula.The dynamics of the formation of black layer showed that the pH values of the oxidized and the reduced layers were both decreasing but in different rates.At the end of the experiments,the average pH attained by the black layer was 7.34 which was the lowest among the three layers.The trend of the change of pH of percolates was quite different from that of the soil.Thus,as biological reduction of sulfate was getting more and more intense in the later stage of the experiment,the pH of the percolates became higher and higher due to their increment of excess of sodium over sulfate ions.As a result,there might have alkali layers with high sodium absorption ratio below the black layer.

    本文以实验室模拟试验,验证了新围垦的盐化水稻土中黑泥层的形成过程。试验证明,即使淋洗液中Na_2SC_4浓度低至0.05%,只要有足够的能源和强烈的还原条件(Eh-100—200mv),很易产生黑泥层。黑泥层中含有大量的Fe~(2+)和S~(2-),这两种离子含量的平均克离子比,接近于FeS的分子式。黑泥层形成过程的动态变化显示,在还原初期,渗漏液中有较多的Si和Fe~(2+)淋出,但后期则明显减少;渗漏液的电导率则随着硫酸盐的还原而逐渐降低。在淋洗和还原过程中,土柱中氧化层和还原层的pH趋向减低,还原层降低更多,但渗漏液的pH则随着硫酸盐的还原而升高。因此,在土壤剖面的下部层次有可能出现较高的钠吸附比,并使pH升高。

    Based on the tests, the paper describes an important function of carbon in the metal globular transfer of coated electrode. The experimental results show that metal globuler are broken to pieces and make the spray and explosive transfer due to entering of car bon in the coalted electrode . The entering ways of carbon are differente the influential degree to the process of globular transfer, is also different.when the tnansfer of carbon in the core wire and. iron alloy of coated electrode, the effect to the modes of draplet transfer is greatest. The oxidation of slag has an effect on functions of carbon in droplet transfer.Strong reducing covering, which entere into a lot of graqhite, often makes the globular thick, when some electrodes are developed, the effective rules of carbon on globular transfer modes are emploged to make the globular thin to improve it'stransfer modes or to repre the oxidation of carbon,so that the spatt-er is reduced and technical level of coated electrode is enhanced.

    本文以实验为基础,阐述碳在焊条金属熔滴过渡过程中的重要作用,指出,碳的加入往往使熔滴破碎,造成熔滴的喷射过渡和爆炸过渡,碳的加入方式不同,对熔滴过渡过程的影响程度也不同,通过焊丝和铁合金过渡碳时,对熔滴过渡形态的影响最大;熔渣的氧化性影响到碳在熔滴过渡过程中的作用的发挥程度。加入大量石墨的强还原性药皮,往往使熔滴粗化。在研制某些焊条时,运用碳在焊接时对熔滴过渡形态影响的规律,细化熔滴,改善其过渡形态,或是抑制碳的氧化,以减少飞溅,提高焊条的工艺水平。
