我们了解装置热风炉生产厂家,又了解了装置之前的准备工作,那现在就由山东众焱机械有限公司带大家了解一下热风炉撤除前的准备工作吧!
  We know the manufacturer of the hot blast stove and the preparation before the installation. Now let Shandong Zhongyan Machinery Co., Ltd. take you to know the preparation before the removal of the hot blast stove.
  在停止热风炉撤除前需求留意的几件事情。由于在运用过程中有压力存在,所以在撤除完成之后一定要留意做好相关的测试,以免留下平安隐患。改造需求现有热风炉的相关部件给予撤除,那么在撤除时要留意关闭鼓风机并中止运转,当炉膛温度降到适宜的温度之后,中止引风机、链条炉排,再由工人从拨火门进入炉膛内,撤除原有炉拱,并将炉膛内部清算洁净,然后再撤除主机以及辅机。那么在撤除前有哪些需求做的准备工作呢?接下来我们就来了解一下。
  Several things need to be noticed before removing the hot blast stove. Due to the pressure in the process of application, it is necessary to pay attention to the relevant tests after the removal, so as to avoid potential safety hazards. It is required to remove the relevant parts of the existing hot blast furnace for transformation. When removing, it is necessary to close the blower and stop the operation. When the furnace temperature drops to the appropriate temperature, stop the induced draft fan and chain grate, then the workers enter the furnace from the fire gate, remove the original furnace arch, clear the furnace interior, and then remove the main engine and auxiliary engine. So what needs to be done before the removal? Let's learn about it next.
  1、撤除现场的交接确认
  1. Handover confirmation of removal site
  撤除前通常要停止现场确认能否停电,水、煤气等介质管道能否曾经关闭,确认无误前方可停止撤除施工。撤除前先将煤气管道用盲板堵死(此项工作普通由甲方担任完成)。关于停炉后马上停止撤除作业的,要在撤除前先翻开炉顶3个人孔并在炉壳上开孔,炉内停止降温,时间。撤除的废料运输,提早准备好自卸汽车,以便及时将撤除的耐材和废料外运。
  Before removal, it is usually necessary to stop the site to confirm whether the power can be cut off, whether the medium pipes such as water and gas can ever be closed, and stop the removal construction before confirming that there is no error. Before removal, the gas pipeline shall be blocked with blind plate (this work is generally completed by Party A). In case that the removal operation is stopped immediately after the boiler is shut down, the top 3 manholes of the furnace shall be opened and holes shall be opened on the furnace shell before the removal, and the temperature in the furnace shall be stopped for one day. For the transportation of the removed waste materials, the dump truck shall be prepared in advance so that the removed refractory materials and waste materials can be transported out in time.

  2、煤气测定及戒备
  2. Gas measurement and alert
  普通在热风主管、烟道管等主管开孔。用煤气报警仪,同时停止气体检测,在气体契合平安请求后,人员进入撤除内部耐材,同时封锁施工区域,沿管道向外15米做为平安区,避免人员进入。同时布置专职人员戒备。撤除前将钢焦东路封路并布置专人停止戒备。
  Generally, holes are made in the main pipes of hot air and flue. Gas alarm shall be used and gas detection shall be stopped at the same time. After the gas meets the safety request, personnel shall enter and remove the internal refractory materials, and the construction area shall be blocked at the same time. 15m away from the pipeline shall be taken as the safety area to avoid personnel entering. At the same time, arrange full-time personnel for alert. Before removal, the East gangjiao road shall be sealed and a special person shall be arranged to stop the alert.
  3、热风炉撤除
  3. Hot blast furnace removal
  撤除前在底部据根底约2500mm的部位停止切口,见图示红线部位。切口前先划线,选派两名气焊从两端间隔空中2500mm位置,向内切割切割角度为170度,高度2500—3000mm的切口。为便当撤除底部耐材,减小倾倒阻力,切口呈图示,便于镐头机进入炉内肃清炉壁及格子砖。沿切口,采用镐头机,将耐材肃清到炉壳1/3---1/4的位置,将前端切口部位的热风炉耐材清算。选两名气焊,沿切口(如红线部位)同时向后部切割,切割到炉壳留1/3,采用液压剪从后部向前推。停止空中崩溃外运和耐材清算。
  Before removal, stop the incision at the bottom about 2500mm from the root bottom, as shown in the red line. Before the incision, draw a line first, and select two gas welding workers to cut the incision with an angle of 170 degrees and a height of 2500-3000mm from the two ends at an interval of 2500mm in the air. In order to remove the bottom refractory and reduce the dumping resistance, the cut is shown in the figure, so that the pickaxe machine can enter the furnace to clean the furnace wall and lattice brick. Along the notch, use a pick machine to clean the refractory to the position of 1 / 3-1 / 4 of the furnace shell, and clear the refractory at the front notch of the hot blast furnace. Select two gas welding workers, cut back at the same time along the center of the incision (such as the red line part), cut to the furnace shell and leave 1 / 3, and push forward from the back with hydraulic shear. Stop air collapse, export and refractory liquidation.
