Deformation greatly promoted carbonitride isothermal precipitation and made C-curve shift leftwards. The position and shape of C-curve depended on the content of Nb and N to a great extent, C-curve shifted leftwards a little when N content increased and its nose temperature was raised with Nb content increased. 3 when cooling rate increased, start temperature and finish temperature of continuous cooling precipitation decreased, full precipitation became difficult to take place, the volume fraction of carbonitride precipitation decreased, molar fraction of Nb and C dissolved in austenite increased, and the precipitation grain was further refined. Deformation shorten precipitation start time during continuous cooling, raised precipitation start temperature, accelerated precipitation kinetics of carbonitrides.

计算表明：1在Fe—Nb—C系统中，随着温度的降低，析出相的平衡体积分数增加，溶解在奥氏体中的Nb、C的摩尔分数降低，析出相中C和Nb的原子分数的比值v增加；2变形大大促进了碳氮化物的等温析出，使C曲线左移，Nb和N的含量与C曲线的位置和形状有一定的关系，N含量的增加，使C曲线略有左移，而Nb的含量的增加使得C曲线的鼻子区上移；3随着冷却速率的增大，连续冷却析出的开始温度和结束温度均有所降低，并且析出变得越来越不充分，析出相体积分数明显减小，溶解在奥氏体中Nb和C的摩尔分数增大，析出相粒子被明显细化，变形大大缩短了CCP过程碳氮化物析出的开始时间，提高了析出的开始温度，促进了析出动力学。

The result shows that Co and Cu are associated with exchangeable fractions, which represents stonger mobility;Pb in iron-manganese fraction represents stonger potential mobility;Zn and Cr existed in oxidizable and residual fraction and Ni in residues represents weak mobility or immobility.

The results showed that the heavy metals in various mediums were mainly Cu and Ni, and those concentrations were, in the descending order, in ditch, tailings, slagheap and cultivated soil. In the tailings and the sludge of the ditch, the concentrations of Ni were obviously higher than those of Cu. Whereas, in the soil and the weathering and atmospheric deposition of the waste slagheap surface, the concentrations of Cu were higher than those of Ni. This means that in the first two mediums, Cu and Ni mainly originated from the tailings, while in the latter two mediums, Cu and Ni mainly came from the atmospheric deposition of airborne particles of the smelting. Cr and Zn were mainly in residual fraction, Cu was mainly in oxidizable and residual fraction.

Firstly, we used the Raman scattering method which can calibrate in real time to measure the O2 (a1 Δ) yield of SOG for the first time in China. The measurement relative error is less than 8%. Based on the data from the experiments, we report the results that the diluent category and ratios influence the O2 (a1 Δ) yield. The relationship of P-τ values and the O2 (a1 Δ) yield of this SOG were given. The effects of distance and bypass of gas transportation on the O2 (a1 Δ) yield are investigated. Secondly, the chlorine utilization was measured by using Raman spectroscopy simultaneously when the O2 (a1 Δ) yield was measured. This method originated with us. The result about the chlorine utilization is coincident with other theoretic and experimental conclusions. The relationship given in this paper between gas stay time in SOG and chlorine utilization offers reference to improve the reaction efficiency and chemical efficiency of COIL. Finally, the partial water vapor pressure at the exit of SOG was measured by absorption spectroscopy. The water vapor fraction and partial pressure have trends changed with the generator total pressure, the diluentratios, and the BHP temperature. These experimental results are very important to improve experimental conditions of SOG, reduce the water vapor fraction, and enhance the output power of COIL.
