剪切波紋鋼纖維 不銹鋼纖維 耐撕裂耐火鋼纖維

鋼纖維簡介

?

? ? 鋼纖維是一種新的混凝土加強材料，適用于對抗拉、抗剪、抗折強度和抗裂、抗中擊、抗疲勞、抗震、抗爆等項性能要求**的結構工程或局部部位；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。

鋼纖維特點

?

? ? 將一定尺寸的耐熱鋼纖維加入由耐火集料、結合劑和外加劑組成的混合料中的可澆注耐火材料稱為鋼纖維增強耐火澆注料。同不加耐熱鋼纖維的澆注料比較，此類澆注料具有如下特點： ①可抑制澆注料在養護、烘烤和高溫使用中產生收縮； ②提高澆注料的韌性、抗機械沖擊性和力學強度； ③提高澆注料的抗熱振性能； ④防止澆注料內產生的微裂紋在熱應力和機械應力作用下擴展或延伸而導致發生斷裂或剝落。

鋼纖維用途

?

? ? 冶金工業
? ? 鋼纖維可用于加熱爐的爐頂、爐頭、爐門、燒嘴磚、出鋼槽槽底、環形爐擋火墻、均熱爐的爐蓋、砂封口、中間包包蓋、電爐三角區、鐵水包襯里、爐外精煉用噴槍，鐵水溝蓋、擋渣堰、高爐中各種耐火料襯里，煉焦爐爐門等。

? ? 水泥工業
? ? 鋼纖維可用于回轉窯的鏈條帶、加熱帶、窯口、加熱器蓋、空氣進口和燃燒管。其它窯的易磨和易沖擊部位。

? ? 石油化工工業
? ? 鋼纖維用于石化裝置中的滑動閥門、裂口區、壓力吹風管、以增加抗震、抗磨能力和降低成本。
鋼纖維可用于傳送線、提升器和旋風呂襯里，用鋼纖維增強后，可防止其分層、起皺、磨損和開裂。燒嘴磚、爐頂、傳送部分和加熱粗嘴，采用鋼纖維澆注料后，**并減少了裂紋和剝落。石油催化裝置煙道采用鋼纖維澆注料后解決了熱震和熱循環問題。

? ? 鋼纖維在石油化工方面的一個 新應用是將它與澆注料一起噴射在襯里的錨固系統，鋼纖維和錨固件一起進行增強，與龜甲網襯里比較，不僅可使總施工費減少50%，而且增強了其抗機械應力的熱應力，經濟效益明顯。

Steel fiber profileSteel fiber is a kind of new concrete strengthening material, suitable for tensile, shear, bending strength and crack resistance, the attack resistance, fatigue resistance, seismic, antiknock items such as structural engineering or local part of the high performance requirements.Widely used in metallurgical industry, refractory material industry, chemical industry;Specific point is widely steel mills, used by metallurgical plant and chemical plant.Such as steel mills steel sink, electrodes, metallurgy factory of furnace wall, furnace door, roof block, etc.Metallurgical industrySteel fiber can be used in the furnace top of heating furnace, oven, oven door, burner brick, tapping baffle wall, ring groove bottom furnace, soaking pit furnace cover, the cover, the sand sealing, electric furnace triangle, hot metal ladle lining, spray gun, refining outside the furnace iron ditch cover, slag dam, all kinds of refractory materials in blast furnace lining, the stove, etc.Cement industrySteel fiber can be used in the rotary kiln chain zone, heating zone, kiln mouth, heater cover, air inlet and combustion tube.Other easy grinding and impact part of the kiln.Petroleum and chemical industrySliding valve, rupture of steel fiber used in petrochemical plant area, pressure blowpipe, to increase the aseismic, anti-wear ability and reduce the cost.Steel fiber can be used for the transmission line, the lifter and cyclone lu lining and steel fiber reinforced, can prevent the layered, wrinkling, wear and cracking.Burner brick, roof, transmission parts and heating crude mouth, after using steel fiber reinforced castable, eliminate and reduce the crack and spalling.Oil catalytic unit flue with steel fiber reinforced castable after solving the problem of the thermal shock and thermal cycling.Steel fiber is a new application in petrochemical industry and castable with jet in the lining of the anchorage system, fiber and the anchoring piece together enhanced, compared with tortoiseshell net lining, not only can reduce the total construction costs by 50%, and enhanced the thermal stress, mechanical stress economic benefit is obvious.
