   角鋼是一種兩邊相互垂直的長條狀的材料。角鋼被廣泛用于制造建筑物的屋頂,一般來講,角鋼可用作電纜支架,也可用于制作面板和機柜的基礎,發電廠和變電站中的電氣面板和機柜的基礎以及固定支架配電箱、接線盒固定架或基礎,也可用于露天倉庫溫室屋架。所以角鋼的質量對我們來說非常重要。

  Angle steel is a kind of long strip material with two sides perpendicular to each other. Angle steel is widely used to make the roof of buildings. Generally speaking, angle steel can be made of cable support, can also be used to make the foundation of panels and cabinets, the foundation of electrical panels and cabinets in power plants and substations, as well as the fixed support distribution box, junction box fixed frame or foundation, can also be used for the outdoor warehouse greenhouse roof truss. So the quality of angle steel is very important to us.
  角(jiao)鋼(gang)是制(zhi)造機械零件最廣(guang)泛使用的(de)(de)金(jin)屬材料。在冶煉、鑄造、開(kai)坯、軋(ya)制(zhi)或連鑄連軋(ya)等(deng)操作加工(gong)之后,角(jiao)鋼(gang)的(de)(de)表面和(he)內(nei)部(bu)可能會有一些缺陷。本文的(de)(de)主要目的(de)(de)是分析角(jiao)鋼(gang)內(nei)部(bu)缺陷產生的(de)(de)原因,對(dui)熱處理工(gong)藝的(de)(de)實施和(he)零件性能的(de)(de)影響(xiang),以及如(ru)何預(yu)防(fang)和(he)補救。
  Angle steel is the most widely used metal material for manufacturing mechanical parts. After smelting, casting, opening, rolling or continuous casting and rolling, there may be some defects on the surface and inside of angle steel. The main purpose of this paper is to analyze the causes of internal defects of angle steel, the impact on the implementation of heat treatment process and parts performance, and how to prevent and remedy.

  熱處(chu)(chu)理(li)(li)技術是(shi)角鋼生(sheng)產過(guo)程(cheng)中常用的一種工藝(yi),是(shi)提高零(ling)件性能和挖掘材料潛力(li)的關(guan)鍵(jian)技術。然而,在熱處(chu)(chu)理(li)(li)生(sheng)產實踐中,基于熱處(chu)(chu)理(li)(li)基礎理(li)(li)論的經驗設計長期以來被用于指導(dao)生(sheng)產,技術人員重復性差、效率(lv)低、勞(lao)動強度(du)高的弱點(dian)逐漸(jian)顯現出來,這是(shi)操作方(fang)面的問題。
  Heat treatment technology is a common process in angle steel production, which is the key technology to improve the performance of parts and tap the potential of materials. However, in the practice of heat treatment production, the experience design based on the basic theory of heat treatment has been used to guide production for a long time, and the weaknesses of poor repeatability, low efficiency and high labor intensity of technical personnel gradually appear, which is a problem in operation.

  The forging ratio of angle steel, that is, the degree of deformation in the forging process, is usually expressed by the section ratio, length ratio or height ratio before and after deformation. When angle steel is forged, it changes in three directions in three-dimensional space, usually measured by the deformation rate in the larger direction. No matter ingot, rolling or continuous casting and rolling, there are some defects in the material due to the crystallization law of molten steel. In order to overcome the adverse effects of these defects, it is necessary to have enough forging ratio so as to completely destroy dendrite and coarse columnar crystal, make them fine and distribute along the main elongation direction; defects such as porosity, porosity and shrinkage cavity in ingot are forged into fine structure, fully reduce segregation and fracture inclusions, and the structure tends to be uniform, so as to improve the performance of angle steel. In the process of angle steel forging, with the increase of forging ratio, the mechanical properties of metal are significantly improved due to the increase of microstructure density and grain refinement. This is a technical problem.
  總之,熱處理技術對于角鋼的加工是非常重要的一個環節,我們在處理的過程中一定要十分的小心,濟南樂豪金屬生產的角鋼可以保證完全符合生產的標準,歡迎您的訂購。
  In a word, heat treatment technology is a very important link for angle steel processing. We must be very careful in the process of processing. The angle steel produced by Lehao metal in Jinan can fully meet the production standards. Welcome to order.
