ABOUT US
RANRUI ENERGY SAVING
Shandong Ranrui Energy Saving Materials Co., Ltd.
Shandong Ranrui Energy-Saving Materials Co., Ltd. is located in Yiyuan County, Zibo City, Shandong Province. The company manufactures and processes fire-resistant insulation materials for marine applications, as well as high-temperature lightweight flue dampers and furnace covers. It also designs, fabricates, and installs modular structures for connecting fire passages and high-temperature flues, and produces aluminosilicate fibers, ceramic fibers, and related products.
Hot Products
A professional manufacturer dedicated to the fields of refractory materials, thermal insulation, fire protection, and heat insulation.
Smoke and fire control enclosure
This flexible fire‑resistant membrane‑encased metal ventilation duct system has passed the national GB/T 17428‑2009 test method for fire resistance of ventilation ducts and meets the 1.0‑hour and 1.5‑hour fire‑resistance requirements (integrity and insulation), thereby satisfying the design criteria for building smoke control and exhaust systems.
Refractory mortar is a novel masonry material formulated by blending powdered materials of the same grade as the bricks being laid, along with binders, moisture-retaining agents, additives, and composite admixtures, all selected to match the temperature rating of the masonry bricks.
A lightweight mullite product prepared by selecting high‑quality, high‑purity refractory powders, adjusting the formulation to meet the specified bulk density, incorporating organic composite fillers, and subjecting the mixture to vacuum extrusion molding followed by high‑temperature sintering and precision finishing.
A lightweight wollastonite product prepared by selecting high‑quality, high‑purity refractory powders and nano‑scale fillers, incorporating pore‑forming agents, stabilizers, and other auxiliary materials, and undergoing forming, firing, and precision finishing.
Made by vacuum forming using ceramic fiber cotton—produced via resistance‑melting and jet‑spinning processes—as the primary raw material, this is a lightweight, flexible refractory fiber insulation material. In addition to inheriting the excellent properties of loose‑type ceramic fiber cotton, it also boasts superior strength and elasticity, making it ideal for expansion joints in furnace and boiler walls as well as for high‑temperature gaskets.
A bulk fiber produced by electrofusion, formed into fibers via blowing or spinning, and requiring no secondary processing or heat treatment.
A new type of refractory insulation material, this product is white in color and features precise dimensions. It integrates fire resistance, thermal insulation, and heat‑retention functions into a single formulation, containing no binders whatsoever. Under neutral or oxidizing atmospheres, it maintains excellent tensile strength, toughness, and fiber integrity. Moreover, it is resistant to oil degradation and can fully restore its thermal performance and physical properties upon drying.
It is manufactured using ceramic fiber wool, natural refractory raw materials, and a small amount of organic binder as the primary ingredients, processed on a fully automated, continuous production line. The product boasts a high fiber content and exhibits excellent performance characteristics, including high-temperature resistance, lightweight properties, and superior thermal shock resistance. It is widely employed as backing material in industrial kilns and as the hot-face lining in low‑temperature kilns, providing robust support for energy savings, reduced consumption, and high‑quality, high‑output operations.
