二、 设备情况cdc是什么缩写
Equipment Condition
热处理生产线配有步进式热处理炉、淬火机、矫直机和自旋式步进冷床，全线自动化控制水平高，热处理质量稳定可靠。
Our heat treatment production line is equiped Step-wi Heat Treatment Furnace, Quenching Machine, Straightening Machine and Self-spin Step-wi Colling Machine. The high level automatization control system ensures steady and first class heat treatment quality.
1、热处理炉ready player one Heat treatment Furnace
步进式热处理炉以冷净煤气为燃料，采用德国施能烧嘴，炉内气氛易于控制，炉温可控制在±5℃以内。
Step-wi Heat treatment Furnace us cold and clean coal gas as fuel, adopts Germany KROMSCHRODER Burner which could ensure the temperature in the furance less than ±5℃.
淬火炉和回火炉均采用步进梁式炉。装出料方式：侧进，侧出；炉子布料：单排连续布料或间隔布料。
Quenching Furance and Tempering Furance both adopt Step-wi Walking Beam Furance.
Mode of Loading and unloading Material: Side Loading, Side unloading. Material Display in the Furance: Single Row Continuesly Display or Interval Display
scol
活动梁和固定梁均为耐热铸钢，顶面带齿形面。每次步进时，钢管都能转动一角度，使钢管加热均匀，并防止在炉内弯曲变形。步进梁能进行正循环、踏步、等高、单动、点动、半自动、自动等功能，升降时对钢管轻托轻放，前进时缓起缓停，无振动冲击和失控现象。同时，具有等高及踏步功能，踏步时向钢管在原齿槽内不断转动。
Walking Beam and Fixed Beam both are fire-endurable cast steel with tooth form on the top. In the process step, steel pipes will be turned for an angle to get symmetrical heating up and avoid bending and distortion in the furnace. Step-wi Beam can carry through Positive Cycle, Mark Time, Equality Height, Single Move, Point Move, Semiautomatic, Automatic functions and so on. Steel pipes are lifted and put lightly when elevating and subsiding, and they are removed and stopped slowly when moving forward. In the process, there is no librating impact and out control phenomenon. And the mechine also has coequal height and Mark Time function to ensure the steel pipes constant turning in the tooth form alveolus.
2、淬火机
Quenching Machine
淬火机具有内喷外淋的功能，外淋水流量大，内喷水速度快，淬火效果好。淬火机可以实现以下功能：
Quenching machine has perfect quenching effect and equiped large flux inner spraying and speedy outer pouring fuction. It can achieve below functions:
abc字母认识外淋+旋转+内喷淬火
Outer pouring + circumgyrate + inner spraying quenching
淬火后具有空水功能（带压缩空气吹扫）
Water emptying function after quenching (with air compressor)
氧化皮采大部分被回水带走，剩余部分停炉时清理
Mostly Oxidation Surface are washed away by backwater, the rest will be cleaned when the furnace stops working.
内喷采用锥形聚能喷嘴（根据处理的钢管不同而不同）
Inner spraying adopts powerfull taper nozzles ( The nozzles are depend on different steel pipes)
淬火前温度850℃左右，淬火后温度低于80℃
The temperature is about 850℃ before quenching and will below 80℃ after quenching.
淬火后钢管端头直度≤2 mm/m，保证钢管顺利进入回火炉。
After quenching, the straight tolerance of the steel pipe’s end should be ≤2 mm/m to ensure the pipe can be placed in the Tempering furnace successfully.
3joyful、矫直机
Straightening Machine
矫直设备采用国内先进的八立柱、四滑架、六辊快开式矫直机，具有机身稳定，矫直速度快，矫直效果好的特点。
Straightening Equipments adopt advanced eight upright column, four slide rack, six rollers rapid opening straightening machine. The mechine is steady, and it has fast straightening speed and perfect straightening effect.
矫直辊采用了2-2-2的对辊辊系，矫直工艺曲线可以实现上弯或下弯式两种方式。
Straightening rollers adopt 2-2-2 rollers so that the straightening technics can be achieved to up bend mode and down bend mode.
采用四立柱滑架结构。矫直辊座安装在动梁上，每个活动梁在四个立柱中垂直滑动，保证矫直过程的稳定。克服了两滑架机型受力偏载的缺点。环球教育
It adopts four upright column slide rack structure.Straightening rollers are installed on the moving beams and every moving beam can slide upright in every four upright column which ensures the stability in the process of straightening. And it conquers the shortcoming of pressure excursion of the two sliding racks.
