Zibo Shuangjian Refractory Materials Co., Ltd. is located in Zichuan District, Zibo City, Shandong Province, China — a region rich in mineral resources and well-known for producing raw materials and finished products for insulation and refractory applications.As one of the five major leading pillar enterprises in Zichuan District, the company has been awarded "Star Enterprise" status for three consecutive years.With more than 10 years of experience in the research, development, and production of refractory materials, our company originated as Zibo Zichuan Jiacheng Refractory Factory. To better meet market demands, upgrade our technical capabilities, and expand production capacity, it was officially restructured and renamed Zibo Shuangjian Refractory Materials Co., Ltd. in 2012.We maintain close technical cooperation with the Institute of Engineering Thermophysics, Chinese Academy of Sciences, and have a strong partnership with Shandong Refractory Materials Factory. Two experienced engineers from Shandong Refractory have been appointed as our Technical Director and Quality Control Manager. Our technical team includes 5 senior engineers/technicians and 9 mid- and junior-lev...

Mainly engaged in the research and production of high, medium and low grade scientific analytical instruments. It is a professional high-tech enterprise with many years of experience in design and manufacturing, integrating Product Research & Development, production, sales and technical services
This is a large-scale rotary kiln, the core equipment in high-temperature industrial production. Our products are applied in industries such as cement, metallurgy, refractory materials, and chemical engineering.
Refractories for Converter Shell Projects,High-performance magnesia-carbon bricks, permanent lining castables, and repair mixes to withstand extreme steelmaking temperatures and erosion.
Refractories for Special Steel & Heavy Forging Projects High-purity corundum & magnesia refractories, including ESR crucible linings, ladle MgO-C bricks, and heating furnace castables, engineered for extreme temperatures, slag resistance, and long service life in high-end alloy production.
2026-05-07The macroscopic physical structure of refractory materials is composed of solid aggregates + matrix + internal pores. The four indicators of bulk density, porosity, water absorption and air permeability essentially characterize the size, quantity, connectivity and distribution structure of internal pores of the materia...
2026-05-06Refractory castable is a finished mixed material containing aggregates (similar to "refractory concrete"), while refractory cement is a pure cementitious powder (aluminate cement). The former can be directly mixed with water for monolithic furnace lining casting, whereas the latter is only used as a binder or...
2026-05-05As core thermal energy equipment in industrial production and civil heating, the operating status of heating kilns is directly related to production efficiency, heating quality, and operational costs. Whether it is material heating and heat treatment in the industrial field or central heating in the civil field, heatin...
2026-05-03In high-temperature industrial scenarios such as iron and steel smelting, cement sintering and chemical reactions, furnace temperatures soar to 1000-2000℃. Under the severe scouring of high-temperature molten materials and continuous corrosion of corrosive gas, ordinary materials soften and damage easily. As a core typ...
2026-05-02The core process of refractory castable construction is: Construction Preparation Mixing Casting and Vibrating Curing and Formwork Removal Oven Drying. The water-to-material ratio and temperature must be strictly controlled throughout the process to avoid cracking and strength loss.
