据通报,本次抽查共抽取了郑州、洛阳、许昌、南阳、濮阳、安阳、新乡、焦作、济源9个省辖市和巩义1个省直管县(市)68家企业生产的120批次耐火材料产品。
本次抽查依据GB/T 2275-2007《镁砖及镁铝砖》、GB/T 22589-2008《镁碳砖》、GB/T 23293-2009 《氮化物结合耐火制品及其配套泥浆》、YB/T 007-2003《连铸用铝碳质耐火制品》、GB/T 2608-2012《硅砖》、GB/T 2988-2012《高铝砖》、YB/T 5011-2014《镁铬砖》、YB/T 5049-2009 《滑板砖》、YB/T 165-1999《树脂结合铝镁碳砖》、 YB/T 113-1997 《烧成微孔铝炭砖》、YB/T 4167-2007《烧成铝碳化硅砖》、JC/T 1064-2007 《水泥窑用硅莫砖》、YB/T 5106-2009《粘土质耐火砖》、YB/T 5107-2004 《热风炉用粘土砖》、《2015年第2批耐火材料产品质量河南省监督抽查实施方案》等标准、法规及相关要求,对耐火材料产品(轻烧镁球、轻烧镁粉)的化学成分质量分数、熔融指数、显气孔率、体积密度、真密度、显密度、常温抗折强度、常温耐压强度、加热永久线变化、荷重软化开始温度、耐火度、高温抗折强度、导热系数、热膨胀率、抗热震性和常温耐磨性等项目进行了检验。
经抽样检验,有118批次产品符合标准要求,2批产品不符合标准要求,涉及到显气孔率项目。
In the second quarter of 2015, Henan Provincial Bureau of Quality and Technical Supervision conducted a provincial supervision and random inspection on the quality of 64 kinds of products such as household paper products (except toilet paper), and announced the results of the random inspection on its official website on the 15th.
According to the report, a total of 120 batches of 68 enterprises in Zhengzhou, Luoyang, Xuchang, Nanyang, Liyang, Anyang, Xinxiang, Jiaozuo, Jiyuan, and Gongyi 1 province directly under the supervision of counties (cities) were sampled in this spot check Refractory products.
This spot check is based on GB / T 2275-2007 "magnesium bricks and magnesia-aluminum bricks", GB / T 22589-2008 "magnesium-carbon bricks", GB / T 23293-2009 "nitride bonded refractory products and their supporting mud", YB / T 007-2003 "Aluminum-carbon refractory products for continuous casting", GB / T 2608-2012 "silicon brick", GB / T 2988-2012 "high alumina brick", YB / T 5011-2014 "magnesium-chrome brick" , YB / T 5049-2009 "Skateboard Brick", YB / T 165-1999 "Resin Bonded Aluminum Magnesium Carbon Brick", YB / T 113-1997 "Fired Microporous Aluminum Carbon Brick", YB / T 4167-2007 " Fired Aluminum Silicon Carbide Bricks ", JC / T 1064-2007" Silicon Molybdenum Bricks for Cement Kilns ", YB / T 5106-2009" Clay Refractory Bricks ", YB / T 5107-2004" Clay Bricks for Hot Air Furnace ", Standards, regulations, and other requirements such as the "2015 Second Batch of Henan Province Supervision and Spot Inspection Implementation Plan for Quality of Refractory Products", the chemical composition mass fraction, melting index, Porosity, bulk density, true density, apparent density, room temperature flexural strength, room temperature compressive strength, heating permanent line change, load softening start temperature, fire resistance, high temperature flexural strength, Heat transfer coefficient, thermal expansion, thermal shock resistance and abrasion resistance at room temperature and other projects have been tested.
After sampling inspection, there were 118 batches of products that met the standard requirements, and 2 batches of products did not meet the standard requirements, which involved apparent porosity items.
