Production Introduction

26-28 Meshes Silicon Nitride Powder for Refractory

Main Feature:
This product is a new material produced at a specific high temperature and pressure environment , the main ingredient is silicon nitride. Si3N4 content above 80% -97.5%. Phase composition and purity can be produced separately according to user requirements. main feature:
 1, It has good corrosion resistance, thermal shock and abrasion resistance. It can be used at a  temperature of 1900 degrees Celsius.
  2,It has an excellent split endurance, very stable chemical composition and thermal conductivity.
  3, The product contains nitride, with characteristics of small swelling, heat conductivity and high  strength and almost no shrinkage about its heat.
  4, It can produce a high temperature oxide film on the surface, and affect the future protection of the interior material not subjected to chemical reaction.

Application Direction 
1) Application of kiln furniture industry. In the Sic material, recrystallized Sic and Si3N4 bonded Sic meet the creep resistance and high strength of demand, but the recrystallized Sic price is too expensive, so people generally choose Si3N4 bonded Sic material.
2) In Metallurgical Industry. Including iron and steel industry billet preheating furnace, electric arc furnace roof industries, as well as aluminum smelting cell, zinc smelting, etc. are used.
3) Applications in the chemical industry. The products are mainly used in mining, organic chemicals, inorganic chemicals various furnace or kiln drying chamber liner, burner nozzles. And widely used in the chemical industry acid, alkali and corrosion resistance.
4) For waste, waste incineration furnace linings. The product is acid erosion, abrasion-resistant ash.

Products Advantage
  1. The silicon nitride bonded silicon carbide is a combination of both performance developed a new high performance refractory products, chemical stability, cold bending strength is 4-8 times that of ordinary refractory material, is the traditional clay bonded silicon carbide  products 2- 3 times, 7- 8 times the normal thermal conductivity of refractory materials, the  thermal  expansion coefficient.
  2. Practice has proved that silicon nitride bonded silicon carbide products having good thermal shock resistance, high temperature creep, acid and alkali, oxidation resistance, aluminum,  lead, tin, zinc and other molten metal erosion.
  3. With Si3N4 bonded Sic products instead of the traditional silicon carbide products, reduce  the kiln to 50% by weight, 16% loading rate of the furnace tank, saving more than 25% of  enterprises to improve  product quality, increase economic efficiency over refractories.
Quality Control
The company pursues "Quality First", "quality of survival," the factory approach, and establish a product quality is the fundamental consciousness in the workforce.
1)  In terms of quality control, from raw materials to finished products are strict quality control procedures in accordance with the requirements of the raw material suppliers are to undergo a rigorous test, after assessment determined to achieve one hundred percent raw materials into the plant qualified rate.
2) The company has a full-time quality control personnel to detect the production of the product tracking, substandard raw materials into the plant can not be, can not be unqualified semi-finished products into the next process, substandard products may not be manufactured, thus ensuring the quality of manufactured products .
3)  With advanced detection equipment and technical means to ensure that customers receive each batch of products qualified
