阳泉铁广今年上半年耐火材料生产任务仅完成98.43％。主要原因是产品质量低废品多。特别是高炉砖的成品率和一级品率都较低,以致不能按期交货。如马鞍山铁厂高炉砖订货规定3月底交货,结果拖延到5月底才交清。该厂上半年耐火砖废品总共有519吨,损失价格达76,514元。废品中尺寸公差占总废品量的1/3,扭曲废品,熔洞废品也不少;特异型粘土砖废品主要是由於裂纹所致。
Yangquan iron wide refractory production tasks in the first half of this year, completed only 98.43%. The main reason is the low quality of products and more scrap. In particular, the yield of finished products and the first grade of blast furnace bricks are so low that they can not be delivered on time. Such as the Maanshan Ironworks blast furnace brick order delivery by the end of March, the result was delayed until the end of May paid. The first half of the plant refractory brick waste a total of 519 tons, the loss price of 76,514 yuan. Waste tolerances in the size of the total volume of waste accounted for 1/3, twisted waste, molten iron scrap a lot; specific clay brick waste is mainly due to cracks.
