安阳钢厂和郑州电焊条厂共同研制成功一种含硫钢瓦。这种瓦,是用一种药皮中含硫较高的电焊条堆焊在钢瓦上制成的。由于硫在受压磨擦时,有一种润滑作用,使钢瓦的耐磨性增强。据安阳钢厂和北京钢厂在1,200毫米薄板轧机上长期使用的结果证明,含硫钢瓦可以完全代替铜瓦,并且比铜瓦的使用寿命高七倍,比铜瓦的成本低70%。如果用来翻修旧钢瓦,每块瓦的费用只相当于铜瓦的十分之一左右。
Anyang Steel and Zhengzhou Welding Factory jointly developed a successful sulfur-containing steel tile. This type of tile is made by over-welding a steel sheet with a high sulfur content electrode in the coating. As the sulfur friction in the pressure, there is a lubricating effect, so that the wear resistance of steel tile increased. The long-term use of Anyang Steel Mill and Beijing Steel Mill on 1,200 mm sheet mills proves that sulfur steel can completely replace copper tiles and is seven times more useful than copper tiles and 70% less expensive than copper tiles. If used to renovate the old steel tile, the cost of each tile is only about one-tenth of the copper tile.
