In order to require of the decarburized layer depth of T11A～T13A carbon tool steel wire rod up to the GB/T1298-1986 standard,the correspond heating processes for roughing soaking pit,pusher-type furnace for structural steel and rail and step-by-step furnace for wire were established based on the feature of T11A～T13A carbon tool and process technology in Pan Steel Co.

为使攀钢T11A～T13A碳素工具钢盘条的脱碳层深度满足GB/T12 98 1986标准的要求，根据T11A～T13A碳素工具钢的特点及攀钢的生产工艺，对初轧均热坑、轨梁推钢式加热炉及线材的步进式加热炉制定了相应的加热工艺，生产出的T11A～T13A碳素工具钢盘条的脱碳层全部满足GB/T12 98 1986标准的要求。

The results show that 82B wire rod brittle fracture is mainly caused by excessive inclusion,reticulate carbide,lower sorbite in the microstructure,and surface defect of wire rod.

结果表明，82B钢盘条脆断的主要原因是夹杂物级别超标、组织中出现网状碳化物、索氏体含量偏低以及盘条表面缺陷等。

It has mainly actions as follows: accumulating steel wire; sending steel wire; drawing steel wire; clipping; tighten; squeezing flat; regulating position of strapper, etc; using annealed rod of φ6.5,φ6.0 or hot-finished rod ofφ6.0 directly as strapping steel wire; it straps and tightens for 720°,and then squeezing flat to make sure that it straps firm and not easily loose.

它具有如下主要动作：蓄丝、送丝、抽丝、剪断、拧紧、挤平、打捆机位置调节等；使用φ6.5，φ6.0的退火盘条或直接采用φ6.0的热轧盘条作捆丝；其捆结拧紧720°，然后挤平，保证了捆结牢固，不易松脱。

The results showed that the main reason of rupture is troostite structure existing in rod.

通过金相、性能和热处理试验，对盘条拉丝断裂原因进行了分析，认为盘条存在屈氏体组织是断裂的根本原因。

By dilatometric change and microscopic test, the critical point at Ac1、Ar1、Ac3 and Ar3 of ML40Cr steel was detemined in Gleeble-3800 the thermal-mechanical simulator. The continuous cooling transformation diagram of ML40Cr steel was obtained by measuring the expanding curves of different cooling rates. The mechanical property and transformation of austenite were analyzed. The proper range of control cooling rate about ML40Cr cold heading steel was found. All those provide the reference for productive practice to develop cold heading steel.

在Gleeble-380热模拟试验机上采用热膨胀法－金相法测定了ML40Cr钢的临界点Ac1、Ar1、Ac3、Ar3，同时测定了在不同冷却速度下过冷奥氏体连续冷却时的膨胀曲线，获得了该钢的连续冷却转变曲线；研究了ML40Cr连续转变冷却过程中奥氏体转变过程和转变产物的组织和性能，初步确定了ML40Cr盘条的控制冷却范围，为冷镦钢ML40Cr盘条的开发提供了参考依据。

It is considered by means of metallographical analyses that the cause for unusual tensile fracture of coarse high carbon wire rod is due to the serious defects of central carbon segregation.

通过金相分析，认为造成大规格高碳钢盘条异常断口的原因是盘条中心存在严重的碳偏析，采用末端电磁搅拌、延长钢坯加热时间和加强铸坯的偏析检验 3条措施可生产出合格盘

This work researched on the control cooling process of ER70S-6 wire rodes which is used for drawing gas shield arc welding electrode.

对用于拉拔气体保护焊丝的焊接用钢盘条ER70S-6的控冷工艺进行了研究，发现提高吐丝温度虽可以降低盘条的强度，但盘条中易出现混晶组织。
