轻烧镁粉出口困局三问 Three Questions on the Predicament of Light Burned Magnesium Powder Export

http://www.ykbhlm.com中国轻烧镁粉资源十分丰富,优质轻烧镁粉矿产——菱镁矿探明储量占世界的22.5%,居世界第一位。特别是辽宁省南部地区拥有世界上罕见的优质菱镁矿资源,保有储量21.66亿吨,占全国储量的61.8%。由于具有储量大、品位高、埋藏浅、易开采等特点,辽宁省的菱镁矿资源具有一定的出口优势。经过几十年的发展,从新中国成立以前封闭落后的耐火材料(轻烧镁球,轻烧镁粉,苦土粉等)供应商到世界轻烧镁粉的供应商,中国轻烧镁粉产业取得了举世瞩目的成就。从1980年以前只有中国五矿一家耐火材料出口商,到千余家出口企业,出口量从1980年12.5万吨增长到最高峰时的200万吨,中国轻烧镁粉产业及出口贸易飞速成长。近二三十年来,我国长期主导着世界钢铁、建材等行业对轻烧镁粉的需求,世界轻烧镁粉用户对中国出口的轻烧镁粉的依存度越来越高。中国作为世界轻烧镁粉用户的主要供应商,每年供应着世界60%的轻烧镁粉需求。其中,辽宁地区的轻烧镁粉出口量占全国的95%。辽宁境内的镁制耐火材料生产企业有几百家,与新中国成立初期相比,出口量增长近百倍。但是,伴随着轻烧镁粉产量及出口量的突飞猛进,中国煅烧氧化镁产业进一步发展的诸多制约因素也逐渐显现。

问题一:由于多年近乎掠夺式的开采,优质镁矿资源的储量飞速下滑,优质矿石开采量逐年减少;

问题二:由于技术进步缓慢,高端轻烧镁粉产品仍被国外生产商控制,特别是利用低品位菱镁矿制取高端轻烧镁粉的技术仍没有取得突破,随着高品质菱镁矿的不断枯竭,镁砂产品质量不断下降;

问题三:中国的镁砂生产与出口企业一直呈现“散、多、小”的现象,行业秩序与标准不够完善。

 

 

http://www.ykbhlm.com China is rich in light-burned magnesium powder resources. The proven reserves of high-quality light-burned magnesium powder—magnesite accounts for 22.5% of the world, ranking first in the world. Especially in the southern region of Liaoning Province, there are rare high-quality magnesite resources in the world, with reserves of 2.166 billion tons, accounting for 61.8% of the national reserves. Due to its large reserves, high grade, shallow burial, and easy exploitation, the magnesite resources in Liaoning Province have certain export advantages. After decades of development, China's light-burned magnesium powder industry, from the suppliers of backward refractory materials (light-burned magnesium balls, light-burned magnesium powder, bitter clay powder, etc.) before the founding of New China to the world's light-burned magnesium powder Achieved world-renowned achievements. From 1980, there was only one refractory exporter of China Minmetals to more than a thousand export companies. The export volume increased from 125,000 tons in 1980 to 2 million tons at the peak. China's light-burned magnesium powder industry and export trade have grown rapidly. . In the past two or three decades, China has long dominated the demand for light-burned magnesium powder in the world's steel and building materials industries. The world ’s light-burned magnesium powder users have become increasingly dependent on China ’s exports of light-burned magnesium powder. As a major supplier of light burned magnesium powder users in the world, China supplies 60% of the world's light burned magnesium powder demand each year. Among them, the export volume of light burned magnesium powder in Liaoning area accounts for 95% of the country. There are hundreds of magnesium refractories manufacturing enterprises in Liaoning. Compared with the initial period of the founding of New China, the export volume has increased by nearly a hundred times. However, with the rapid development of the output and export volume of light-burned magnesium powder, many constraints on the further development of China's calcined magnesium oxide industry have gradually emerged.

Problem 1: Due to the near-predatory mining for many years, the reserves of high-quality magnesium ore resources have fallen rapidly, and the amount of high-quality ore mining has decreased year by year;

Problem 2: Due to the slow technological progress, high-end light-burned magnesium powder products are still controlled by foreign manufacturers, especially the technology for making high-end light-burned magnesium powder with low-grade magnesite has not yet made a breakthrough. With the high-quality magnesite The quality of magnesite products continues to decline;

Problem three: China's magnesite production and export enterprises have been showing a phenomenon of "discrete, more, and smaller", and the industry order and standards are not perfect.
