Introduction
Shandong Shengchuan New Material Science and Technology Inc.
Shandong Shengchuan New Material Science and Technology Inc. (hereinafter referred to as Shengchuan New Material) was founded in July 2015 ,Located in Zichuan, covering a floor area of 33,000 square meters and a building area of 10,000 square meters, the company has over 60 staff members including 10 technicians and 5 expert technic advisers.
Shengchuan New Material is a scientific and technic innovation-based enterprise majoring in producing advanced inorganic nonmetal material. Currently, the main products of phase 1 project include pure aluminate cement series (brand VICAL) and high-purity calcium hexa-aluminate compound material (brand RECAG) with an annual design capacity of 30,000 tons respectively. After reaching design capacity, the annual output value can reach 240,000,000 yuan. Meanwhile, the products have good industrial policy guidance (energy efficiency, environmental protection and consumption reduction) and positive social significance (sewage anticorrosion).
Pure Calcium Aluminate Cement (refractory Binder)-RECAG-90 is a new kind of synthenic refractory aggregate with high purity and density, based on the mineralogical phase of calcium hexaluminate (CA6), a special mineral phase with unique microstructure, having the following characteristics different from the conventional refractory aggregates: High chemical purity ( impurities of SiO2, Fe2O3, etc are at very low level ) and high refractoriness (onset of melting 1830 °C); Low thermal conductivity compared with other refractory materials at a similar density, especially with corundum material (including fused corundum and sintered tabular alumina); Low solubility in iron slag. RECAG-90 can be used in the application of exposition to direct contact with liquid steel; High stability at strong reducing atmosphere (such as CO). RECAG-90 can be applied in petrochemical, coal chemical, ammonia and other industries;Low wettability by molten non-ferrous metals and slag (especially metal aluminium). RECAG-90 has good properties of erosion resistance, penetration preventing, suitable for the lining of smelting furnace of high purity aluminium; High chemical resistance in alkaline environment. RECAG-90 has been used in a kiln outlet of large size cement kiln Relative lower consumption and lower cost when RECAG-90 replace denser corundum material in final refractory product under same performance; As a kind of dense refractory aggregate, RECAG - 90 can be used to produce shaped bricks and monolithics. In refractory monolithics, RECAG-90 shows good adaptability and compatibility for most kinds of additives, micropowders. Thus this feature provides more flexibility for the optimization of formula. In addition, RECAG - 90 can be widely employed with all kinds of installation methods, including casting, self-flowing, gunning and wet shotcreting, etc.
RECAG - 90 is manufactured with sintering process. Its stable quality, ensured by serious online monitoring and control of its mineral phase, provides and guarantees successful site-installation performance and flexible formula design.
