Chinese Magnesia Industry in Liaoning Province: Highlight of High-performance manufacturers

China’s magnesia enterprises in Liaoning province, a major production hub, get along with the comprehensive management, such as policies of environmental protection and government environmental inspection, as well as the outbreak of the coronavirus in recently, the whole industry and market continued to face challenges. It is the time to realise the important of how to revolution, changing of supply chain, from the biggest supplier only model transform to high-performance manufacturers.


Introduction

The 8th Liaoning International Magnesium Material Exposition, China (hereinafter referred to as "The 8th CLIMME") was founded in Shenyang, Liaoning Province, China since 2004, which has been held once every two years.


The past CLIMMEs have been a great success, and all the trade negotiations are actively. Cumulative exhibitors are more than 1600, which include more than 80 foreign well-known enterprises to participate in the exhibition. The visitors are nearly 150,000 including 60,000 professionals and more than thousands of foreign businessmen. The CLIMME has covered a wide range of activities, such as exhibitions, trade, technical seminars and talent exchange, which is the important magnesium materials exposition for worldwide professional research, business trade and science and technology exchange.

Situation and Development of Magnesium Industry in Liaoning

There are 27 mining areas distributed in 9 provinces of China. Liaoning province is the main storage site for magnesite, which has advantages of high grade, shallow bury and easy open mining. In Liaoning province, the reserves are distributed in Haicheng, Dashiqiao, Xiuyan, Fengcheng, Kuandian, Fushun and Liaoyang, etc.

The magnesium refractory products from Liaoning province, China, cover almost 90% domestic market share and 60% international market share. The production of magnesium refractory materials in Liaoning occupy 90% of national total output and take up to 60% of international total output.

From Anshan to Yingkou, there are 65 mining areas, which include 11 large-scale mining areas owning more than 91% of estimated reserves. Around those regions also have 91 production mines, the annual production is about 15.59 million tons, which include 7 large-scale mines accounting for more than 50% of total production.


In Liaoning, there are nearly 500 enterprises producing and processing of magnesium materials, which include more than 3500 different kinds of kilns using to processed raw materials and refractory products, the annual output is around 20 million tons. Qualified magnesium companies in Liaoning Province, only take 23.4% in total, almost 400 companies.


Most of them produce CCM, DBM, mid-grade magnesia, high pure magnesia, FM, dolomite magnesia, magnesia-synthetic, magnesia-carbon brick, magnesia-calcium brick, magnesia-alumina spinel brick, other kinds of magnesia composite materials, and refractories, which mainly be applied for high temperature industry, such as steel, cement, nonferrous metallurgy, and glass, etc.

In Liaoning, most magnesium minerals and materials are used to make refractories, magnesium chemical materials, building materials and magnesium functional materials, etc.

Scenario Analysis of Manufactory and Pollutions

The Caustic Calcined Magnesite is made between 700℃ to 1000℃ from nature magnesite through calcining in reverberatory furnace, rotary furnace and boiling furnace. The Dead Burned Magnesia is made between 1500℃ to 1800℃ and the Fused Magnesia is made between 2500℃ to 3000℃. Tunnel Kiln can be used to make MgO-based bricks. From 2020, energy consumption per unit of industrial added value will be reduced by 18%.

Reform the foundation of industry to build high performing processing and increase the quality of products, which needs energy-saving and environmental friendly technology and equipment.
