The invention provides a method for vacuum treatment of low-carbon low-sulfur steel and removal of residual elements tin and antimony at the same time. The method comprises the following steps: melting down steel containing tin and antimony in an inert atmosphere at the smelting temperature of 1550-1700 DEG C, adding 0.01-0.1% of aluminum ingot, carrying out deoxidation treatment for 10-30 minutes, adding 10-20% of FeS-Na2S slag, reacting for a certain time, and carrying out slag removal operation; and then vacuum refining is conducted on the molten steel under the pressure of 10-670 Pa, stirring is conducted for 5-15 min at the same time, and the molten steel with tin and antimony removed is obtained. The FeS-Na2S slag added in the method improves the activity of the residual elements tin and antimony, and meanwhile, tin and antimony can react with the added S element to generate sulfide with higher saturated vapor pressure, so that the residual elements are easier to volatilize. Therefore ...

Принадлежит:

The invention provides a face expression automatic labeling method and system, and the method comprises the steps: obtaining a face image, and selecting a face image with a peak expression as an expression image data set; selecting a one-fifth face image in the data set, and manually marking emotion labels of expressions of the one-fifth face image; and constructing a model framework based on self-supervised learning. In the auxiliary task, an Officient-CapsNet model is used as an encoder for facial expression feature extraction, unlabeled expression images in the expression image data set are sent into the encoder for feature extraction, feature representation is compared and learned, and a pre-training model is obtained; in downstream tasks of self-supervised learning, training and fine tuning are carried out on a labeled data set obtained by the pre-training model, and a final automatic labeling model is obtained; and automatically labeling the facial expression images obtained in the ...

The invention provides a method for removing a residual element antimony in medium and low carbon molten steel. The method comprises the following steps: melting down the antimony-containing steel in an inert atmosphere at the temperature of 1550-1650 DEG C; covering the surface of the antimony-containing molten steel with a certain content of calcium-silicon-aluminum refining slag for desulfurization treatment; then adding a certain amount of aluminum particles to carry out deep deoxidation treatment; and then adding a refining agent calcium carbide of which the content is 10-50wt% of the total mass of the calcium-silicon-aluminum refining slag, stirring, and carrying out slagging-off treatment to obtain the antimony-removed medium-low carbon steel liquid. According to the method, the removal rate of antimony in the steel reaches 30.6-46.8%, and the sulfur content can be controlled at an extremely low level. According to the method, the antimony removal efficiency and the low production ...
