  reaction adsorption
During and immediately following the oxygen-sulfur interaction, oxide buildup appeared to be limited by a surface reaction (adsorption, ionization, or dissociation).
      


The oxidation rates of molten cuprous sulphide were examined with variations of temperature,oxygen concentrations and air flow rates. The results showed that the oxidationrates of conjugate solution of Cu-Cu_2S sys- tem are constant,that is,the percentage of desulphurization of Cu_2S vers time is a straight line relationship.The slopes of the straight-lines increase with temper- atures,oxygen concentrations in the air and air flow rates. Effect of oxygen partial pressures: When Po_2<0.60 atm d(s%)/dt=k,=2.2×10~(-2).Po_2+0.82(S%/min.cm~2)....

The oxidation rates of molten cuprous sulphide were examined with variations of temperature,oxygen concentrations and air flow rates. The results showed that the oxidationrates of conjugate solution of Cu-Cu_2S sys- tem are constant,that is,the percentage of desulphurization of Cu_2S vers time is a straight line relationship.The slopes of the straight-lines increase with temper- atures,oxygen concentrations in the air and air flow rates. Effect of oxygen partial pressures: When Po_2<0.60 atm d(s%)/dt=k,=2.2×10~(-2).Po_2+0.82(S%/min.cm~2). When Po_2>0.6~1.0 atm, k_t=14.5×0~(-2)(S%/min.cm~2). The kinetic equation is: d(S%)/dt=k_t=(k·Po_2)/(β+k_2·Po_2) Effect of temperature: The specific rate constant increases with temperature,and the logarithmic rate constant vers 1/T(K)is a straight-line relationship.The equation of rates constant as function of temperature is: k_t-5.45×10~(-1)×exp[-7100/RT](S%/min.cm~2) which activation energy E=7100 cal/mol. Effect of air flow rates: When the air flow rate is below 200 cm~3/min,the rate constant increases with flow rates.Consequently,the rate of oxidation process is regarded as limited by oxygen diffusion in the gasphase at a definite temperature(1200℃).When the air flow rate is larger than 200 cm~3/min,the specific rate constant remains unchanged. Consequently,the velocity of oxidation process is determined by the rate of chemical reaction. Order of Reaction: The results show that at 1200℃ in the Cu-Cu_2S conjugate solution the desulp- hurization kinetics of Cu_2S is first order with respect to the oxygen partial pressure and zero order with respect to the sulphur concentration when Po_2<0.60 atm, i.e. d(S%)/dt=Ks.Po_2+A d(△S%/△t)/d(S%)=0 When Po_2>0.60 atm,the desulphurization kinetics is zero order with respect to the oxygen partial pressure and sulphur concentration. d(△S%/△t)/d Po_2=0 d(△S%/△t)/d(S%)=0 In the low sulphur single phase the desulphurization kinetics is first order with respect to the oxygen and sulphur concentrations,i.e. d(S%)/dt=Km(S%)Po_2+B In the plots of reaction rates against concentration of sulphur according to fol- lowing equations: d(△S%/△t)/d(S%)=0 d(△S%/△t)/d(S%)=-Km(constant) a turning-point of phase transformation of Cu_2S from conjugate solution to single phase is shown.At the turning-point of reaction rate,its sulphur content in the melts beginning to form single phase is 1.2 wt% at 1200℃. As to the activities of Cu_2S the similar forms of equations are obtained. At the turning-point of phase transformation,its sulphur content in the melts beginning to form single phase is 1.28 wt% at 1200℃. In the commercial copper converting practice,such as 40~50 ton furnace,the air- flow rates is about 400~500 M~3/min,equivalent to 6~8 M~3/ton Cu_2S.The oxidation rate is either gas phase control or liquid phase control. In our experiments,the air flow rate used exceeded 200 cc/min,corresponding to 13.3 M~3/ton Cu_2S.Under this condition neither the gas diffusion nor the liquid dif- fusion is the rate-determining step.Consequently,the data show that the chemical reaction adsorption is the rate-determining step in the oxidation of conjugate solution of Cu_2S. According to above kinetic equations the end-point of converting process may be controlled by continuous analysis of SO_2% during the white-metal blowing period.

本文研究了富氧吹炼、温度及空气流量等因素对熔体 Cu_2S 氧化脱硫速度的影响。试验结果表明,在 Cu—Cu_2S 体系中,反应速度为一常数,即在体系分层区,脱硫量与吹风时间成直线关系。直线斜率即反应速度随氧浓度、温度和空气流量的增高而增大。白冰铜(Cu_2S)在吹炼过程中的反应级数,在分层区:当Po_2<0.60atm 时,与氧分压为一阶反应,与硫浓度为零阶反应;Po_2>0.60atm 时,与 Po_2及硫浓度均为动力学上的零阶反应。在分层后的低硫单相区,用空气吹炼,与硫浓度及 Po_2均为一阶反应。试验还验证了:温度在1200℃时,用空气吹炼,脱硫速度由分层区转入低硫单相区时,有显著的转折点,与此转折点相应的含硫量约1.2%左右,和由热力学计算所得1.28%的含硫量相差不大。转折点以后的脱硫速度的降低,与含硫浓度的减少成直线关系,与硫活度的降低成比例。根据转折点前后的动力学方程式,讨论了铜转炉吹炼第二周期终点的控制问题。由于吹风量大,Cu—Cu_2S 系分层区吹炼过程的限制步骤,为氧分子在界面上的吸附作用,其动力学方程式与 Langmuir 等温吸附相似。

The experiments,judged by the primacy characteristics of the grinding fluids were carried out for the long chain alcohol and the halogenated hydrocarbon compositions.The results show that two kinds of organic substance and the compounds which include both of them can enhance efficiency of the engineering ceramic grinding greatly.The infrared spectrum testing shows that alcohol soaking on the ceramics mainly formed interface chemical reaction adsorption membrane.And under conditions of the high temperature and high pressure,alcohol rubs with ceramics to produce the friction-polymer which are attributed to the excellent friction and wear reduction.When adding with the halogenated hydrocarbon compositions,the grinding fluids possess extreme pressure property which can lubricate surface of the ceramics sufficiently and arise the efficiency further.Moreover,the specific heat was studied for the first time.As a result,the greater the specific heat is,the higher machining efficiency will be.

以磨削液的第一类性能作为主要评价指标,对长碳链醇和卤代烃(CCl4)组成的多种配方进行了切入式磨削效率试验。结果表明,这两种有机物及其多种复配配方可以大幅提高氮化硅陶瓷磨削时的材料去除率。通过红外光谱测试发现,醇类磨削液与陶瓷间润滑膜的结合方式以化学吸附为主,并在摩擦高温条件下产生了具有良好减摩作用的烷氧基硅或聚烷氧基硅。卤代烃的加入可以进一步使磨削液具有良好的极压性能,并提高磨削效率。此外,首次引入质量热容作为分析手段,对使用上述磨削液时陶瓷材料去除率的影响因素进行了探讨。结果表明,氮化硅陶瓷磨削时的材料去除率随着热容的增大而提高。
