Custom-Engineered Solutions
By pioneering new energy-saving refractory materials and innovating kiln lining designs, we dedicate ourselves to helping clients achieve energy conservation and emission reduction goals.
Production Market
We have established long-term business cooperation and joint product R&D projects with leading design institutes, including:Dalian Design & Research Institute of ACRE (Coking & Refractory Engineering Consulting Corporation, MCC)),Shandong Metallurgical Design Institute Co., Ltd,Changsha Research Institute of Mining and Metallurgy (CRIMM), Minmetals.
High Refractoriness
Sillimanite blocks boast exceptional refractoriness. Their temperature resistance ranges from 1770 to 1830 degrees Celsius. And their load-softening temperature falls between 1600 and 1650 degrees Celsius. This makes them suitable for prolonged operation at high temperatures.
High Structural Strength
Sillimanite bricks exhibit remarkable structural strength. They have a cold Crushing Strength (CCS) of 45-60 MPa. This high mechanical strength translates to superior abrasion resistance and bending strength.
Strong Resistance to Acid and Alkali Corrosion
This brick demonstrates exceptional resistance to chemical attack from acids, alkalis, and other corrosive media, including molten glass.
Excellent Thermal Shock Resistance
With a Permanent Linear Change (PLC) of -0.1 to 0.1%, sillimanite bricks exhibit remarkable dimensional stability and structural integrity under rapid temperature fluctuations.
High Workability
Refractory to its needs by offering customized cutting and processing of sillimanite bricks. This facilitates convenient installation and construction.
Energy Saving and Emission Reducing
Sillimanite refractory blocks possess low thermal conductivity. This feature effectively retains heat within high-temperature equipment to minimize heat loss and reduce energy consumption.

Sillimanite brick belongs to neutral refractory. It is made of sillimante minerals, which can transform into mullite and free silica after high temperature firing. It is produced by the methods of high temperature firing and casting.
Pressed Sillimanite Brick Maufacturing Progress
Select Qualified Raw Materials
The production of grouting products first selects qualified refractory raw materials , at the same time, according to the shape of the product, a gypsum mold is prepared, and a binder (electrolyte) is prepared, and then prepare the mud required for injection molding.
Casting of Mud
The qualified mud is slowly injected into the mold. After the filling, the mud is flattened, the gypsum board (upper formwork) is covered, and then the mold is released. The demolding time is determined according to the thickness of the blank, and the blank is formed after the inside and outside. To repair the light, that is, to repair the blank.
Forming Shape
The formed semi-finished products should be dried to a certain amount of moisture, and then kiln and high temperature fired into finished products, processed in the neck, processed, and shipped.
