Description
Technical field
The present invention relates to furnace equipment repairing technique field more particularly to a kind of siliceous soldering materials.
Background technique
The high temperature kiln used at this stage mainly includes glass furnace and two kinds of coke oven, service life in furnace life of these two types of kilns compared with
Long, glass furnace can achieve 15 years or so, and coke oven then can achieve 20 to 40 years, since the maintenance that stops midway is to the resistance to material of kiln
Damage it is especially big, therefore repair when mostly use ceramic welding technology.
However at this stage ceramic welding technology be not it is very mature, for coke oven, soldering material need after welding and
Refractory brick originally have it is higher be firmly combined degree because coke loading and unloading can ceaselessly butt welding complement in coke production
It rubs, and during coke oven soldering maintenance, the temperature of kiln constantly declines, this is to soldering material and coke oven original refractory material
Combination be unfavorable, it is therefore desirable to soldering material have oneself heating ability, however after existing coke oven soldering material soldering with original
The conjugation of refractory matter is poor, easily cracked under the rubbing action of furnace charge or even fall off.
