Description

阀门锻前恒温加热炉
技术领域
本发明是一种加热炉，特别是一种阀门锻前恒温加热炉，本加
热炉能将毛坯加热到可锻温度范围。
背景技术
阀门的加工过程，其中必不可少的工序是用加热炉对毛坯进行锻前加热。但目前所采用的加热设备效率很低，其最主要的原因是现有设备是以煤油喷灯为加热工具，加热环境为开放式，热量流失很多，能源利用率极低。另一方面，当前的加热技术难以准确控制温度，使得出炉的毛坯温度波动大，极大地影响了最终阀门的质量。
发明内容
本发明的目的是为了克服现有阀门锻前加热技术热效率低下、温度控制不准确的缺陷，发明一种阀门锻前恒温加热炉，本加热炉不仅能大大提高热效率，而且能准确控制毛坯出炉温度。
本发明的目的是按如下的方式来实现的：所述阀门锻前恒温加热炉，包括炉外框和炉内框，炉内框通过支柱设于炉外框内；炉内框的两端各设有一支架，支架的中央开有一个或一个以上进料导轨孔，进料导轨孔的周边开有多个炉丝管孔，炉丝管孔的外侧设有多个冷却棒套管槽；通过进料导轨孔设有进料导轨，进料导轨的两端分别从炉外框伸出；通过炉丝管孔设有炉丝管，炉丝管的两端嵌在炉丝管孔内，炉丝管内设有炉丝；冷却棒套管槽上设有冷却棒套管，冷却棒套管上设有冷却棒；炉丝的两端与冷却棒固接，冷却棒的另一端与外部电路连接；炉外框和炉内框之间设有外保温层，炉内框与炉丝管之间设有内保温层；一温度传感器套管穿过炉内框和炉外框并固定在内保温层和外保温层上，温度传感器套管上设有温度传感器。
本发明的积极效果如下：本发明可将毛坯加热到可锻温度的范围，其加热效率高，并能准确控制毛坯的出炉温度，大大节约了生产成本和提高了产品的质量。

 具体实施方式
如图1图2图3图4所示，所述阀门锻前恒温加热炉，包括炉外框1和炉内框2，炉内框2通过支柱3设于炉外框1内；炉内框2的两端各设有一支架4，支架4的中央开有一个或一个以上进料导轨孔5，进料导轨孔5的周边开有多个炉丝管孔6，炉丝管孔6的外侧设有多个冷却棒套管槽7（见图3图4）；通过进料导轨孔5设有进料导轨8，进料导轨8的两端分别从炉外框1伸出；通过炉丝管孔6设有炉丝管9，炉丝管9的两端嵌在炉丝管孔6内，炉丝管9内设有炉丝10；冷却棒套管槽7上设有冷却棒套管11，冷却棒套管11上设有冷却棒12；炉丝10的两端与冷却棒12固接，冷却棒12的另一端与外部电路连接，通过外部电路可以调节炉丝10两端的电压，从而控制炉丝10的发热功率；炉外框1和炉内框2之间设有外保温层13，炉内框2与炉丝管9之间设有内保温层14；一温度传感器套管15穿过炉内框2和炉外框1并固定在内保温层14和外保温层13上，温度传感器套管15上设有温度传感器16，通过温度传感器16可以获知实时炉温，从而实现炉温的闭环控制。
使用中，待加热的毛坯一个接一个地从进料导轨的进料端进入，以一定速度从进料导轨的出料端出来，在此期间，炉丝管对其加热，可将毛坯加热到可锻温度的范围。
