The invention discloses a continuous casting method. The method performs drawing by using a drawing and straightening unit comprising a plurality of drawing and straightening machines, wherein the plurality of drawing and straightening machines are arranged so that a continuous casting billet successfully passes through each drawing and straightening machine. The method comprises the following steps of: keeping a dummy bar pressure pressed downwards through the drawing and straightening machine when a billet head of the continuous casting billet enters every one of the plurality of drawing and straightening machines; and converting the pressure applied by the first drawing and straightening machine in the plurality of drawing and straightening machines into a first hot billet pressure smaller than the dummy bar pressure through the dummy bar pressure before the billet head enters the last drawing and straightening machine in the plurality of drawing and straightening machines.

The invention discloses a production method of low-sulfur vanadium trioxide, which comprises the following steps: mixing ammonium polyvanadate and washing water, pulping, pre-washing, and carrying out solid-liquid separation to obtain low-sulfur ammonium polyvanadate; heating and reducing the low-sulfur ammonium polyvanadate by using a reducing agent to obtain vanadium trioxide; water is added into the vanadium trioxide for washing, after solid-liquid separation, drying is performed to obtain filtrate and low-sulfur vanadium trioxide, and the filtrate is circularly used as washing water in the step (1). According to the method, the low-sulfur vanadium trioxide product is produced under the condition of low liquid-solid ratio on the basis of different characteristics of vanadium trioxide and ammonium polyvanadate washing impurity sulfur, the washing water consumption in the vanadium trioxide production process can be reduced, the problem of impurity sulfur content in vanadium trioxide is ...
