连续型热处理炉的改进设计

Improvement design of continuous type heat treatment furnace

为解决传统热处理炉维修周期长、生产环境差、功率消耗大等问题,对其进行改进：（1）参数设计及优化。给出热处理炉总功率、加热时间和炉长的计算方法,改进后的热处理炉加热温度为950℃,Dv值为40 mm·m/min,可处理1.0~2.5 mm钢丝10根。（2）热处理炉改为分体式结构,上下同时采用电加热,结合处采用快卸式压紧螺栓压紧。保温和耐火材料采用晶体纤维加热模块、纤维板和纤维保温毯等,破损的保温材料可回收使用。（3）电气部分采用智能型温控仪加可控硅控制。以国内某公司为例,热处理炉改进后使用半年,钢丝产量比炉体改造前高出5%,消耗电量降低2.5%,综合统计增加经济效益约15.2万元。

In order to solve the problems such as maintenance period long, production environment poor, power consump- tion big of traditional heat treatment furnace, improvements are as follows ： （ 1 ） parameter design and optimization, the total power of heat treatment turnace, heating time and calculating method of furnace length are given, the heating temperature of improving heat treatment furnace is 950 ~C ,Dr value is 40 mm ~ m/min,can treat diameter 1.0 -2.5 mm 10 steel wires. （2） heat treatment furnace changes into separable structure, upper and lower adopts electric heating at the same time, joint section adopts quick release type bolt to compact, heat insulating and refractory material adopts crystal fiber heating mod- ule, fiber board and fiber blanket and so on, damaged heat insulating material can be recycled use. （3） electric part adopts intelligent temperature controller adding controllable silicon to control. To take some domestic company as example, heat treatment furnace improvement after half a year use, output of steel wire is higher than before furnace body improvement a- bout 5% , electric consumption decreases about 2.5% ,comprehensive statistics increases economic benefits about 152 thou- sands yuan.
