礦用w鋼帶廠家
W鋼帶是一種新型礦山支護和隧道支護材料,該產品可與各種錨桿共同組織組合錨桿支架,通過它可以把分散的多根錨桿聯接起來形成一個整體承載結構,顯著的提高錨桿的整體效果,在不完整頂板巖層中,對處理不穩定圍巖效果較佳。
w鋼帶因其橫截面很像字母“W”而得名,w鋼帶材質為Q235。
w鋼帶也叫頂板鋼帶,是以縱剪帶鋼為原料,經多組軋機連續冷彎輥壓成形的型鋼產品。
w鋼帶是一種新型礦山支護和隧道支護材料,作用是與錨桿組合共同組成錨桿支護網架,起到巖壁或巷道的支護作用。w鋼帶廣泛應用于礦井下巷道,工作面切眼,硐室及其他領域的巷道支護,對處理不穩定圍巖效果更佳。
W鋼帶產品特點
1.可根據不同的地質條件和作業環境進行型號選擇;
2.抗彎截面模量提高37倍,向下截面模量約是向上截面模量的2.75倍,所以在安裝時,采用錨桿鉆機向上頂緊;
3.與其他類型鋼帶比,W鋼帶更不易撕裂,而且鋼度大,提高70倍左右;
4.冷軋過程中的硬化作用,提高抗拉強度12%—15%;
5.截面利用率高,節省材料、價格低廉。
W鋼帶四大特色
1、原料采用高強合金帶鋼; 通過冷壓變成W型帶鋼,根據長度要求截斷,再進行打孔;
2、具有更高的鋼性和強度;
3、W鋼帶抗彎截面模量提高54倍;
4、W鋼帶在冷壓過程中的硬化作用可提高抗拉強度28-46%。
W鋼帶性能規格
常用寬度為:180mm,200mm,220mm,250mm,280mm,300mm
常用厚度為:2.5mm,2.75mm,3.0mm 常用孔徑為:40mm*60mm 30mm*70mm
w鋼帶的長度可以根據客戶實際需求定做。
w鋼帶把分散的多根錨桿聯結起來形成一個整體承載結構,顯著地提高錨桿支護的整體效果,在不完整的頂板巖中應用效果更好。有降低支護成本,節省支護鋼材等優點。
