Reactor for producing titanium sponge by magnesium reduction method

The invention discloses a reactor for producing titanium sponge by a magnesium reduction method. The reactor consists of a flange, a cylinder body and an end socket; the flange is arranged at the upper portion of the cylinder body, and the sealing head is arranged at the lower part of the cylinder body; and the interval between the inner diameter of the flange and the outer diameter of the cylinder body is 1-2 mm, and a welding seam is welded between gaps. When the reactor is welded, firstly, manual bottom sealing welding is adopted, then argon arc welding and groove filling welding are adopted to ensure the welding strength of the reactor, and the welding seam with the gaps of 1-2 mm prevents bursting, so that the safe production of the quality of a titanium sponge product is ensured, the production cost is saved, and the labor intensity of operators is reduced. 一种用于镁还原法生产海绵钛的反应器，由法兰、筒体和封头组成；在筒体上部设置法兰，在筒体下部设置封头；法兰的内径与筒体的外径之间间隔1-2mm,在间隙之间焊接焊缝。在焊接反应器时，首先采用人工封底焊，然后才是氩弧焊，坡口填焊保证反应器的焊接强度，间隙1-2mm的焊缝防止炸裂，从而保证海绵钛产品质量
