Shandong Refractory Materials Group Lunai Kiln Industry Co., Ltd. (formerly Shandong Refractory Materials Factory), is affiliated to Shandong Iron and Steel Group. It is a large state-owned refractory backbone enterprise with a history of 113 years.

In April 1904, Boshan Glass Company, the predecessor of the enterprise invested by the Qing government, was established. Boshan Glass Company is a flat glass manufacturing enterprise, which is the "glass" for the manufacture of glass in China's new law. Later, after the late Qing Dynasty, the Republic of China, and the Japanese puppet rule, the company's name was changed to Boshan Glass Company, Shandong Model Kiln Factory, Shandong Provincial Lift Kiln Test factory and Boshan Kiln Industry Co., Ltd.; Boshan was liberated for the fifth time in March 1948, and the enterprise was state-owned; it was renamed Shandong Kiln Industry Co., Ltd. in 1949, and Shandong Refractory Materials Factory in September 1954; Shan in May 2001 Some of the advantageous assets of Naichang were reorganized and established Shandong Lunai Kiln Industry Co., Ltd. was reorganized in 2010 through the reform of the property rights system and was reorganized as Shandong Nui Materials Group Lunai Kiln Industry Co., Ltd.

The company covers an area of ​​385,000 square meters, with more than 800 employees and more than 150 technical personnel of various types, including 10 senior professional titles and more than 360 talents of various operational skills. In line with the environmentally friendly, green, energy-saving, low-consumption and intelligent technical development and environmental protection requirements of the retardant materials industry, the company has successively automated the transformation of major production equipment such as ingredients, presses, and sintering, and newly built or renovated desulfurization and denitrification environmental protection equipment. Four energy-saving tunnel kilns have been completed, and the equipment manufacturing capacity and automation level have been continuously improved.

Relying on the century-old corporate management advantages and deep accumulation of technology, the company is committed to providing high-quality refractory materials for steel, building materials, nonferrous metals, military industry, chemical industry, electronics, energy, environmental protection and other industries. The products cover clay, high alumina, corundum-mullite More than ten series of quality, red column, carbon composite materials, as well as high-quality synthetic materials, ambiguous materials, light bricks, oxide non-oxide special refractory products, etc., are widely used in blast furnaces, hot air furnaces, coke ovens, dry extinguishing In high-temperature fields such as coke, carbon roasting furnace, iron transport and pretreatment, ladle tundra, heating furnace, activated lime kiln, waste incinerator, waste slag resource recycling calciner kiln, etc., the annual refractory material production capacity is 100,000 tons. In recent years, the company's business revenue, profit and tax have continued to grow, of which nearly 50% of the products are exported to Europe, the United States, Japan, South Korea and other countries and regions; the "Lu Nai Kiln Industry" brand has a high social reputation in the refractory materials industry. As for recognition, the company's leading product "Ryostone low-creep bricks for hot air furnaces" has a national market share of more than 40%, and the national market share of "Ryostone and Mullite Silicon Carbide bricks for dry quenching devices" has a national market share of It has reached more than 60%, and the national market share of "alumina hollow ball products" has reached more than 40%.

After 112 years of ups and downs, and after several generations of unremitting efforts, especially under the correct leadership of Shangang Group and Shandong Refractory Materials Group, the company insists on implementing its brand strategy and internationalization strategy, insists on relying on technological progress, and actively builds domestic and foreign The market competitive advantage, relying on the deep accumulation of enterprise management and technology for a century, has continuously achieved external adaptation and internal adjustments. By promoting internal marketization, it has achieved rapid response to the external market, and the market adaptability has been significantly enhanced.

With continuous innovation ability and good product quality, and with the corporate spirit of "trust as ever as a mountain, innovation and transcendence", the company relies closely on the workers and the masses, unite their efforts and strive for progress, and in various aspects such as production and operation, product research and development, lean management, etc. We have made continuous progress, and our ability to adapt to the market and serve the society has been greatly improved and has leaped onto a new development platform, and have grown into an internationally advanced and domestically first-class refractory material production company.
