The company established Shandong Wanqiao Group Co., Ltd. in January 2006. The company covers an area of �6�7�6�7120,000 square meters, with 500 employees and 120 scientific and technical personnel. The annual refractory production capacity is about 200,000 tons. The main product series are silica bricks and clay bricks for coke ovens, clay bricks for blast furnaces, hot blast stoves, high alumina bricks, silica bricks, clay bricks for glass kilns, high-quality silica bricks, zero-expansion silica bricks, large glazed bricks, and low porosity. Bricks, low-cement vibration forming pool bottom bricks, tin bath bottom bricks, high alumina bricks, synthetic sillimanite bricks. Using Belgian production technology to produce front lip bricks, rear lip bricks and lead bricks for heat-resistant concrete flat glass grid lines. It also produces various insulation materials, zircon bricks, sintered zirconium corundum bricks, ramming materials, castables of various materials, zirconium, siliceous thermal repair materials, high-quality silicon fire clay, clay fire clay, and siliceous plastic thermal insulation Materials and other unshaped refractory materials.

The company has a domestic advanced clay, high-alumina, and siliceous granular mud preparation center. The main equipment includes: 5 jaw crushers, 1 dry mill, 4 cone crushers, 5 counter-rolling machines, and ball mills. 9 sets, 2 sets of Raymond machines, 16 sets of powerful and efficient iron removers, 2 sets of automatic electronic batching systems, 12 sets of kneading machines; the company has a complete domestic semi-finished product preparation center, and the main equipment includes: automatic hydraulic brick press 5 Sets (1,250 tons, 630 tons, 200 tons, 150 tons), 1 630-ton press, 9 500-ton presses, 10 400-ton presses, and 22 315-ton presses , The corresponding steel mold manufacturing center, drying system and semi-finished product inspection and selection system; the company has a relatively complete tunnel kiln firing system in China, the main equipment is: 128m natural gas tunnel kiln automatic production lines, 200m natural gas tunnel kiln automation 3 production lines, 1 180-meter natural gas tunnel kiln and matching temperature control system, 8 high-temperature shuttle kilns (three of which are 150 cubic meters, two are 100 cubic meters, one is 50 cubic meters, and two are 10 cubic meters. ); The company has a relatively strict domestic finished product inspection system and finished product packaging system.

The company passed the ISO9001:2008 standard quality certification on December 8, 2004, and passed the occupational health and safety management system OHSAS18001:1999 and environmental management system ISO14001:2004 certification on May 26, 2011, and the provincial AAA level standardization certification. After the examination and acceptance of the National Refractory Quality Inspection Center of Luoyang, the National Production License Office issued coke oven silica bricks, blast furnace clay bricks ZGN-42, GN42, and blast furnace high alumina bricks GL-65, GL- on June 26, 2008. 55. GL-48 production license, complete testing methods, and sound quality control system. Shandong Provincial Refractory Research Institute was established in our company in 2016, mainly researching and developing new products.

The company is a coke oven, blast furnace, and hot blast furnace designated by MCC Dalian Coking and Refractory Research Institute and Shanxi Saiding Engineering, Beijing Zhongliansheng, Shandong Metallurgical Design Institute, China Light International, China Building Materials Design Institute, Qinhuangdao Design Institute, and Bengbu Glass Design Institute. , Glass furnaces, carbon furnaces, glass float lines, grid normal lines, large bricks and various refractory materials designated production units. In recent years, the company has actively participated in international market competition, and its products have been sold to the United Kingdom, Canada, Mexico, Japan, Argentina, Colombia, Pakistan, Indonesia, India, Iran, Thailand, Vietnam, South Korea, Brazil, Congo (Brazzaville) and other countries. Through the production of refractory materials over the years, the company has accumulated rich production experience. From model design, raw material formulation, particle grading, mixing, molding, firing, selection, packaging of finished products to shipment, the relevant characteristics of the series of refractory materials have been mastered, and the production of refractory materials has been improved. We warmly welcome customers to come to our company for inspection and guidance.
