几年来国家工农业建設上所采用的电焊条,无論国产或进口的产品,在塗料类型方面广泛受欢迎的多屬于二氧化钛型。此类焊条的特点,机械性能虽比其它类型略低,但它有很好的焊接工艺性能,操作方便,焊縫成形美观。在总路线的光輝照耀下,由于鋼铁工业飞跃的發展,焊条的需要量将迅速增長,如果大量消耗进口钛白粉,从經济意义的角度来看,是很大的浪费。因此我們考虑采用天然二氧化钛即金紅石来制造钛型焊条。金紅石在 Over the past few years, national industrial and agricultural construction used by the welding electrodes, whether domestic or imported products, widely accepted in the type of paint are mostly titanium dioxide type. The characteristics of such electrodes, mechanical properties, although slightly lower than other types, but it has good welding performance, easy to operate, weld appearance. Under the brilliant light of the general route, due to the rapid development of the iron and steel industry, the demand for welding rods will rapidly increase. If large amounts of imported titanium dioxide are consumed, it is a waste of economy from an economic point of view. Therefore, we consider the use of natural titanium dioxide rutile to manufacture titanium electrodes. Rutile
