After partition wall structure steel fabrication completes, by water outlet of water tank (4) blind plate sealing, then mouth of pipe water flowing pressurization in the middle of water cooled pipeline (2), carry out bulge test to water-cooled pipe-line system, test pressure gets the 1.25-1.5 of design pressure doubly;
3rd step, build preparation before amorphous refractory:
1) after bulge test completes, then water cooled pipeline (2) middle part and the coated one deck refractory fiber blanket (9) of lower surface, and with adhesive tape refractory fiber blanket (9) twined tie up fixing;
2) at anchoring piece external coating one deck water proofing asphalt;
4th step, build amorphous refractory (7):
1) according to need the specification of rectangular wall body, the method adopting formwork to build builds amorphous refractory (7);
2) rectangular wall body built up is watered to amorphous refractory (7) and carry out maintenance aftershaping, reach mounting condition.
The preparation method of water-cooled partition wall in 11. a kind of stoves that can install online according to claim 10, it is characterized in that: the rectangular wall body in shown 4th step is divided into three formworks to build from top to bottom, first build lower floor's amorphous refractory (7), after its maintenance is shaping, builds middle level amorphous refractory (7) again, builds upper, middle and lower three layers of amorphous refractory (7) by that analogy.
In 12. 1 kinds of stoves that can install online, the installation method of water-cooled partition wall, is characterized in that comprising the steps:
1) installing hole that body of heater (10) top is reserved is opened, by clean for the cleaning of periphery amorphous refractory surface; Fix a circle refractory fiber blanket (9) on the surface of installing hole, this refractory fiber blanket (9) wraps with plastic sheeting in advance;
2) this water-cooled partition wall is entered body of heater (10) installing hole by hoisting machine tool integral hoisting, hanging girder steel (3) hanging is on furnace roof crossbeam, closely knit by clogging between this water-cooled partition wall and body of heater (10) with the refractory fiber blanket fixed in step 1) (9);
3) two-layer refractory brick is added a cover at the sealing surface of body of heater (10) installing hole and this water-cooled partition wall;
4) first outer to water outlet of water tank (4) and stove drainpipe is connected, outer to the mouth of pipe in the middle of water cooled pipeline (2) and stove water inlet pipe is connected, and water flowing; So far, partition wall enters running status.
