质检总局：轻烧镁球产品抽检不合格率8.75% General Administration of Quality Supervision, Inspection and Quarantine: 8.75%

     http://www.ykbhlm.com中国经济网北京7月29日讯 28日，国家质检总局公布轻烧镁球产品质量国家监督抽查结果，有7批次产品不符合标准的规定，不合格产品检出率为8.75%。 中国经济网记者了解到，2015年第二季度，共抽查了河北、辽宁、上海、江苏、浙江、安徽、山东、河南等8个省、直辖市80家企业生产的80批次轻烧镁球产品。

     依据GB/T22589-2008《轻烧镁球》等标准的要求，对轻烧镁球产品的碳含量、氧化镁含量、显气孔率、体积密度、常温耐压强度、高温抗折强度等6个项目进行了检验。本次在集中产区辽宁抽查了48批次产品，不合格产品检出率为10.4%，高于全国平均检出率。大石桥市金源耐火材料厂、大石桥市鑫昌炉料厂、营口光辉特种耐火材料有限公司、营口宏林矿产品有限公司、鞍山市量子炉材集团有限公司各有一批次产品被检出不合格，涉及常温耐压强度、显气孔率、体积密度、氧化镁含量、碳含量等项目。

     与此同时的抽查中，营口波海菱镁材料有限公司等耐火材料公司均符合国家质量要求。

On the 28th, the General Administration of Quality Supervision, Inspection and Quarantine announced the results of the national supervision and inspection of the quality of light-burned magnesium balls. The product detection rate was 8.75%. China Economic Network reporter learned that in the second quarter of 2015, a total of 80 batches of lightly burned magnesium balls produced by 80 enterprises in 8 provinces and municipalities including Hebei, Liaoning, Shanghai, Jiangsu, Zhejiang, Anhui, Shandong, and Henan were spot-checked. .

     According to the requirements of GB / T22589-2008 "light burned magnesium balls" and other standards, the carbon content, magnesium oxide content, apparent porosity, bulk density, room temperature compressive strength, and high temperature flexural strength of light burned magnesium ball products are 6 The project was inspected. This time, 48 batches of products were spot-checked in Liaoning. The detection rate of unqualified products was 10.4%, which was higher than the national average detection rate. Dashiqiao Jinyuan Refractories Factory, Dashiqiao Xinchang Furnace Factory, Yingkou Guanghui Special Refractories Co., Ltd., Yingkou Honglin Mineral Products Co., Ltd., Anshan Quantum Furnace Group Co., Ltd. Qualified, involving items such as room temperature compressive strength, apparent porosity, bulk density, magnesium oxide content, and carbon content.

     At the same time, the refractory companies such as Yingkou Bohai Magnesite Materials Co., Ltd. all met the national quality requirements.
