鋼纖維介紹

鋼纖維是廣泛應(yīng)用的一種新的混凝土加強(qiáng)材料，適用于對(duì)抗拉、抗剪、抗折強(qiáng)度和抗裂、抗沖擊、抗疲勞、抗震、抗爆等項(xiàng)性能要求較高的結(jié)構(gòu)工程，廣泛應(yīng)用于道路、機(jī)場(chǎng)、橋梁、水工、 港口、鐵路、礦山、隧道、軍事及工業(yè)和民用建筑等工程領(lǐng)域。

為增強(qiáng)砂漿或混凝土粘結(jié)強(qiáng)度而加入長(zhǎng)度和直徑在一定范圍內(nèi)的細(xì)鋼絲，常用截面為圓形的長(zhǎng)直鋼纖維，其長(zhǎng)度為10~60毫米，直徑為0.2~0.6毫米，長(zhǎng)徑比為30~100。為增加纖維和砂漿或混凝土的界面，可選用各種異形的鋼纖維，其截面有矩形、鋸齒形、彎月形的;截面尺寸沿長(zhǎng)度而交替變化的;波形的;圓圈狀的;端部放大的或帶彎鉤的等。

鋼纖維常見的型號(hào)有：446# 430# 304# 310#。以4字開頭，除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?yàn)樗鼈冇幸粋€(gè)共同的特點(diǎn)，就是含有鉻(Cr). 4字頭鋼纖維都含有耐蝕性貴金屬：鉻（Cr），因?yàn)镃r的強(qiáng)耐蝕性，所以廣泛被用于冶金行業(yè)，耐材行業(yè)，化工行業(yè)，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。

鋼纖維優(yōu)越性

1.裂縫控制，鋼纖維對(duì)混凝土結(jié)構(gòu)起到加固作用。

2.鋼纖維分布密度對(duì)地坪裂縫的彌散作用大，能充分控制地坪裂縫的寬度。

3.由于鋼纖維本身具有很高的抗拉強(qiáng)度（大于100MPa），鋼纖維在混凝土中有效傳送與分配應(yīng)力，使裂縫化解為散置的微細(xì)裂縫。

4.由于鋼纖維提高了混凝土板的韌度和延性，因而在控制混凝土變形裂縫方面，鋼纖維的增強(qiáng)效果尤佳。

5.可提高工程抗沖擊性，耐磨性及疲勞強(qiáng)度和韌性?；炷聊途眯杂行Ц纳啤p少?zèng)_擊和摩擦所產(chǎn)生的表面損失。

6. 鋼纖維和混凝土具有很強(qiáng)的握裹力，對(duì)大幅度溫度變化具有較佳抗力；在溫度驟然上升和下降的情況下會(huì)產(chǎn)生剝落裂縫現(xiàn)象明顯減少。

鋼纖維用途

1.鋼纖維主要用于制造鋼纖維混凝土，任何方法生產(chǎn)的鋼纖維都能起到強(qiáng)化混凝土的作用。

2.超細(xì)鋼纖維主要用于增強(qiáng)塑料及石棉摩擦材料。

3.用于冶金行業(yè)，耐材行業(yè)，化工行業(yè)。

4.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。

5.廣泛應(yīng)用于道路、機(jī)場(chǎng)、橋梁、水工、 港口、鐵路、礦山、隧道、軍事及工業(yè)和民用建筑等工程領(lǐng)域。

英文翻譯

Steel fiber is a kind of widely used new concrete strengthening material, suitable for tensile, shear, bending strength and crack resistance, the attack resistance, fatigue resistance, seismic, antiknock and so on a high performance requirements of structural engineering or local area. Is widely used in roads, airports, Bridges, water, ports, railways, mines, tunnels, military, industrial and civil building engineering, etc.

Join for reinforced mortar or concrete bond strength within a certain range in length and diameter of fine wire, cross section is commonly used for round long straight steel fiber, the length of 10 to 60 mm, 0.2 ~ 0.6 mm in diameter, the length to diameter ratio is 30 ~ 100. To increase the fiber and cement mortar or concrete interface, can choose a variety of special-shaped steel fiber, the cross section is rectangular, zigzag, meniscus; Along the length and cross section size variations; The waveform; The circle shape; End amplification or belt hook, etc.

Steel fiber common types are: 446 # 430 # 304 # 430 #. Begin with four words, besides 446 #, with four words beginning with 430; All begin with four words of steel fiber, is a stainless steel fiber, because they have a common characteristic, is containing chromium (Cr). 4 "contain the corrosion resistance of steel fiber for precious metals: chromium (Cr), because of strong corrosion resistance of Cr, so widely used in metallurgical industry, refractory material industry, chemical industry, widely steel mills, used by metallurgical plant and chemical plant. Steel mill of steel water tank, for example, electrodes, metallurgy factory of furnace wall, furnace door, roof block, etc.

Steel fiber superiority

1. The crack control, steel fiber on concrete structure reinforcement effect.

2. Steel fiber distribution density of dispersion effect in floor crack, can fully control the width of the floor cracks.

3. Due to the tensile strength of steel fiber itself has very high (more than 100 mpa), steel fiber effective transmission and distribution of stress in the concrete, dissolve for scattered micro cracks.

4. Because of the steel fiber can improve the toughness and ductility of concrete plate, so in terms of control the deformation of concrete crack, steel fiber enhancement effect is best.

5. Can improve the engineering impact resistance, abrasion resistance and fatigue strength and toughness. The durability of concrete effectively improve. Reduce the impact and friction surface generated by the loss.

6. Has a strong grip of fiber and concrete, has better resistance to temperature significantly change; In the case of temperature rising and falling sharply produces the flaking cracks phenomenon is significantly reduced.

Steel fiber USES

1. Steel fiber is mainly used in the manufacture of steel fiber reinforced concrete, any method in the production of steel fiber can have the effect of reinforced concrete.

2. The ultrafine steel fiber is mainly used for reinforced plastic and asbestos friction material.

3. Used in metallurgical industry, refractory material industry, chemical industry

4. Widely steel mills, used by metallurgical plant and chemical plant. Steel mill of steel water tank, for example, electrodes, metallurgy factory of furnace wall, furnace door, roof block, etc.

5. Widely used in roads, airports, Bridges, water, ports, railways, mines, tunnels, military, industrial and civil building engineering, etc.
