C型钢都是由C型钢成型机自动加工成型的。槽钢是截面为凹槽形的长条钢材。其规格以腰高(h)*腿宽(b)*腰厚(d)的毫米数表示,如120*53*5,表示腰高为120毫米,腿宽为53毫米,腰厚为5毫米的槽钢,或称12#槽钢。腰高相同的槽钢,如有几种不同的腿宽和腰厚也需在型号右边加abc予以区别,如25a#25b#25c#等。工字钢也称钢梁(英文名称IBeam),是截面为工字形的长条钢材。工字钢分普通工字钢和轻型工字钢,H形钢三种。H-型钢是由工字型钢优化发展而成的一种断面力学性能更为优良的经济型断面钢材,尤其断面与英文字母“H”相同而得名。H型钢分为宽翼缘H型钢(HW)中翼缘H型钢(HM)窄翼缘H型钢(HN)薄壁H型钢(HT)H型钢桩(HU)工字钢HWHMHNH型钢的区别工字钢翼缘是变截面靠腹板部厚,外部薄;H型钢的翼缘是等截面HWHMHNH是H型钢的通称,H型钢是焊制;HWHMHN是热轧HW是H型钢高度和翼缘宽度基本相等;主要用于钢筋砼框架结构柱中钢芯柱,也称劲性钢柱;在钢结构中主要用于柱HM是H型钢高度和翼缘宽度比例大致为1.33~~1.75主要在钢结构中:用做钢框架柱在承受动力荷载的框架结构中用做框架梁;例如:设备平台HN是H型钢高度和翼缘宽度比例大于等于2,主要用于梁;工字钢的用用途相当于HN型钢;1、工字型钢不论是普通型还是轻型的,由于截面尺寸均相对较高、较窄,故对截面两个主袖的惯性矩相差较大,因此,一般仅能直接用于在其腹板平面内受弯的构件或将其组成格构式受力构件。对轴心受压构件或在垂直于腹板平面还有弯曲的构件均不宜采用,这就使其在应用范围上有着很大的局限。2、h型钢属于高效经济裁面型材(其它还有冷弯薄壁型钢、压型钢板等),由于截面形状合理,它们能使钢材更高地发挥效能,提高承裁能力。不同于普通工字型的是h型钢的翼缘进行了加宽,且内、外表面通常是平行的,这样可便于用高强度螺桂和其他构件连接。其尺寸构成合理系列,型号齐全,便于设计选用。3、h型钢的翼缘都是等厚度的,有轧制截面,也有由3块板焊接组成的组合截面。工字钢都是轧制截面,由于生产工艺差,翼缘内边有1:10坡度。H型钢的轧制不同于普通工字钢仅用一套水平轧辊,由于其翼缘较宽且无斜度(或斜度很小),故须增设一组立式轧辊同时进行辊轧,因此,其轧制工艺和设备都比普通轧机复杂。国内可生产的最大轧制h型钢高度为800mm,超过了只能是焊接组合截面。我国热轧H型钢国标(GB/T11263-1998)将h型钢分为窄翼缘、宽翼缘和钢桩三类,其代号分别为hz、hk和hu。窄翼缘h型钢适用于梁或压弯构件,而宽翼缘h型钢和h型钢桩则适用于轴心受压构件或压弯构件。工字钢与H型钢相比,等重量前提下,w、ix、iy都不如h型钢五、工字钢单位重量表热轧普通工字钢每米重量表型号尺寸(毫米)截面面积(厘米2)理论重量(公斤/米)hbdtr110100684.57.63.314.311.212.61267458.43.518.114.214140805.59.13.821.516.9161608869.9426.120.518180946.510.74.330.624.120a200100711.44.535.527.920b200102911.44.539.531.122a2201107.512.34.8423322b2201129.512.34.846.436.425a250116813548.538.125b2501181013553.54228a2801228.513.75.355.4543.428b28012410.513.75.361.0547.932a3201309.5155.867.0552.732b32013211.5155.873.4557.732c32013413.5155.879.9562.836a3601361015.8676.359.936b3601381215.8683.565.636c3601401415.8690.771.240a40014210.516.56.386.167.640b40014412.516.56.394.173.840c40014614.516.56.310280.145a45015011.5186.810280.445b45015213.5186.811187.445c45015415.5186.812094.550a5001581220711993.650b5001601420712910150c5001621620713910956a56016612.5217.3135.25106.256b56016814.5217.3146.4511556c56017016.5217.3157.85123.963a63017613227.5154.9121.663b63017815227.5167.5131.563c63018017227.5180.1141热轧轻型工字钢每米重量表型号尺寸(毫米)截面面积(厘米2)理论重量(公斤/米)型号尺寸(毫米)截面面积(厘米2)理论重量(公斤/米)hbdthbdt10100554.57.212.09.4618180905.18.123.418.412120644.87.314.711.518a1801005.18.325.419.914140734.97.517.413.7202001005.28.426.821.016160815.07.820.21520a2001105.28.628.922.7222201105.48.730.624.0404001558.013.071.456.122a2201205.48.932.825.8454501608.614.283.065.2242401155.69.534.827.3505001709.515.297.876.824a2401255.69.837.529.45555018010.316.511489.8272701256.09.840.231.56060019011.117.813210427a2701356.010.243.233.9656502001219.2153120303001356.510.246.536.5707002101320.817613830a3001456.510.749.939.270a7002101524.0202158333301407.011.253.842.270b70021017.528.2234184363601457.512.361.948.6六、槽钢单位重量表热轧普通槽钢每米重量表型号尺寸(毫米)截面面积(厘米2)理论重量(公斤/米)型号尺寸(毫米)截面面积(厘米2)理论重量(公斤/米)hbdthbdt550374.576.935.4414a1405869.518.5114.536.363404.87.58.4446.6314b1406089.521.3116.738804358110.248.0416a160636.51021.9517.2310100485.38.512.741016160658.51025.1519.7412.6126535.5915.6912.3718a18068710.525.6920.171818070910.529.2922.9928c2808611.512.551.2240.2120a2007371128.8322.6332a3208881448.7038.22202007591132.8325.7732b32090101455.1043.2522a22077711.531.8424.9932c32092121461.5048.282222079911.536.2428.4536a3609691660.8947.8025a2507871234.9127.4736b36098111668.0953.4525b2508091239.9131.3936c360100131675.2950.1025c25082111244.9135.3240a40010010.51875.0558.9128a280827.512.540.0231.4240b40010212.51883.0565.1928b280849.912.545.6235.8140c40010414.51891.0571.47热轧轻型槽钢每米重量表型号尺寸(毫米)截面面积(厘米2)理论重量(公斤/米)hbdtr1550324.47.02.56.164.846.565364.47.22.57.515.90880404.57.42.58.897.0510100464.57.63.010.908.5912120524.87.83.013.3010.414140584.98.13.015.6012.314a140624.98.73.017.0013.316160645.08.43.518.1014.216a160685.09.03.519.5015.318180705.18.73.520.7016.318a180745.19.33.522.2017.420200765.29.04.023.418.420a200805.29.74.025.219.822220825.49.54.026.721.022a220875.410.24.028.822.624240905.610.04.030.624.024a240955.610.74.032.925.827270956.010.54.535.227.7303001006.511.0540.531.8333301057.011.7546.536.5363601107.512.6653.441.9404001158.013.5661.548.3七、轨道材料重量表钢轨每米重量表钢轨类型(公斤/米)尺寸(毫米)截面面积F(厘米2)理论重量(公斤/米)高A度底B宽头C宽腰D厚轻轨55044224.56.415.0386554257.010.768.421180.566327.014.3111.20159176377.018.8014.721890804010.023.0718.0624107925110.931.2424.46重轨331201106012.542.533.28638134114681349.538.73431401147014.557.044.653501521327015.565.851.514鱼尾板每块重量表钢轨类型尺寸(毫米)横截面面积(厘米2)每块加工后的重量(公斤)鱼尾板标准号ABCD5公斤/米2122652561.760.269YB229-638公斤/米2703070703.490.687YB228-6311公斤/米35832100947.111.91YB227-6315公斤/米3723610010010.122.78YB226-6318公斤/米扁平型372361001008.52.33YB225-63角型10.93.0324公斤/米4265010012614.864.73YB14-6333公斤/米38~43公斤/米5907906516014021.1226.019.4115.57YB351-63YB185-63型材的有关实用知识一、型材的分类1.简单断面型钢①方钢——热轧方钢、冷拉方钢;②圆钢——热轧圆钢、锻制圆钢、冷拉圆钢③线材④扁钢;⑤弹簧扁钢;⑥角钢——等边角钢、不等边角钢;⑦三角钢⑧六角钢;⑨弓形钢;⑩椭圆钢2.复杂断面型钢①工字钢——普通工字钢、轻型工字钢②槽钢——热轧槽钢(普通槽钢、轻型槽钢)、弯曲槽钢③H型钢(又称宽腿工字钢)④钢轨——重轨、轻轨、起重机钢轨、其他专用钢轨⑥窗框钢⑦钢板桩⑧弯曲型钢——冷弯型钢、热弯型钢⑧其他二、型钢中大、中、小型的划分大型中型小型工字钢高≥180mm高<180mm槽钢高≥180mm高<180mm等边角钢边宽≥160mm边宽50-140mm边宽20-45mm不等边角钢边宽≥160×100mm边宽140×90-50×32mm边宽≤4
