Preparation inflatable element, insufflation composite brick and composite brick blowing

The present invention discloses blowing device, blow composite brick and producing a composite brick blowing, blowing passage is provided in the channel and attempts to prevent seepage inflatable element, the barrier attempts to prevent two or two channels, respectively one or more blowing fluid communication channels. Blowing and blowing device of the present invention, the blowing element having tiles, bleeding hardly occurs in actual use steel during the blow process is not blocked passageway blowing, blow through rate, thereby reducing the amount of oxygen blowing, reduction smelting costs; blowing duty ratio also reduces the amount of blowing brick ablation, thereby extending the life of the brick blow, reducing the cost of smelting.
