鋼纖維產品介紹

?

? ? ? 446#是鋼纖維的一種牌號，以4字開頭，除開446之外，以4字開頭的還有430等；凡是以4字開頭的鋼纖維，都是不銹鋼纖維，因為它們有一個共同的特點，就是含有鉻.

鋼纖維產品優質

?

? ? ? 不銹鋼纖維是采用**新冶金工藝熔體快淬法，把耐熱不銹鋼熔體一次抽取而成，它與通常冶金工藝的鋼纖維相比，具有以下優點：工藝流程短，價格便宜；快淬工藝使鋼纖維具有微晶結構，強度和韌性高；纖維的橫截面呈不規則月牙形，表面自然粗糙，與耐火料基體結合力強；有良好的高溫強度和高溫耐腐蝕性。

鋼纖維用途

?

? ? ? 4字頭鋼纖維都含有耐蝕性貴金屬：鉻，因為Cr的強耐蝕性，所以廣泛被用于冶金行業，耐材行業，化工行業。具體點就是被廣泛的鋼廠，冶金廠和化工廠所用。比如，鋼廠的鋼水槽，電極，冶金廠的爐壁，爐門，爐頂封蓋等。

?

? ? ? 將不銹鋼纖維摻入耐火材料基體后，可大大提高耐熱構筑物的抗熱循環沖擊性能，耐熱等級及抗磨耗性能，可使耐火材料和工業爐窯的使用壽命延長數倍至幾十倍，防止或減少高溫裂紋，提高抗彎強度，提高抗急熱急冷性能和提高導熱系數，從而提高工作效率，降低生產成本。

446# is a trademark of steel fiber, with 4 words at the beginning, but 446, 4 and 430 at the beginning of the word; usually 4 words at the beginning of the steel fiber, are stainless steel fiber, because they have a common characteristic, is containing chromium .
The stainless steel fiber adopts the new metallurgical technology, melt spinning, to melt a heat-resistant stainless steel and steel fiber extraction, compared it with the usual metallurgy process, has the following advantages: short process, low price; the rapid quenching process of steel fiber has a microcrystalline structure, strength and toughness high; the fiber cross-sectional irregular crescent, the natural rough surface, strong adhesion and refractory material substrate; with high temperature strength and good corrosion resistance at high temperature.
4 "steel fiber containing precious metals: corrosion resistance of chromium , because of the strong corrosion resistance of Cr, so widely used in metallurgical industry, refractory industry, chemical industry. Specific points are being used by a wide range of steel mills, metallurgical plants, and chemical plants. For example, steel tank, steel electrode, furnace wall, metallurgy factory door, top cover etc
The stainless steel fiber into the refractory matrix after thermal cycle impact performance can greatly improve the heat resistance of structures, thermal stability and anti abrasion performance, can make the refractory materials and industrial furnaces, prolong the service life of several times to several times, to prevent or reduce crack at high temperature, high bending strength, improve resistance to rapid heating and cooling performance and to improve the thermal conductivity, so as to improve work efficiency, reduce production costs.
