230 of brick of   clay of magnesia brick 460 is fireproof Pouring magnesia brick of 920 of magnesia brick of 1215 of magnesia brick of 690 of magnesia brick of 300 of brick of clay of electric stove of ore of nickel of copper of 30000kV·A of company of nickel of north of Russia of makings 136 Fireproof Pouring broken bits of makings 920 boiler setting uses water-cooling those a footpath between fields to overcome chromium of 300 of brick of clay of electric stove of concentrate of 31500kV·A copper nickel below chromic magnesia brick of 1150 of chromic magnesia brick of 1150 of chromic magnesia brick of magnesia brick 920 is fireproof and pouring 1040 of chromic magnesia brick of 300 of brick of clay of electric stove of concentrate of nickel of copper of 45000kV·A of Lin Gong department of Nuo of   of makings 1170 is chromic magnesia brick Knot 1060

Producing the discovery in practice, the configuration of hearth is bad, its are main defect is: (1) hearth bottom make it returns form of whole of form of arch shape form fireproof and pouring makings base, both sides tall, intermediate bottom, intermediate part is large only 150 ~ 200mm, the integral type base of six to one of this kind of thickness, cannot bear not only weight of body of heater of 1000 ~ 2000t, and do not expand in order to get used to different heat with inhomogenous sink, bring about fireproof and pouring makings base disintegrate, cause leakage furnace; (2) side wall and hearth joint are seam continuously, aborning often appears strip is interstitial, cause leakage furnace.

After improving the configuration of hearth, become with saggar brick build by laying bricks or stones turn over vaulted base, replace original fireproof and pouring makings base, foot of the arch that turn over arch and furnace circumstances have sex be in the stage that use a fault to press build by laying bricks or stones to replace original seam continuously. And, the argillaceous brick of wet build by laying bricks or stones must stoving is rear but magnesia brick of build by laying bricks or stones turns over arch; If argillaceous brick layer and magnesia brick turn over arch,carbonado together after step is good, will rise because of the damp of base, make pulverization of superstratum magnesia brick.

(2) boiler setting

The height of electric stove boiler setting of fusion copper concentrate or cupreous nickel concentrate is in 8.7m less than, side wall advocate build with magnesia brick build by laying bricks or stones under line of the wall of end wall, broken bits, the wall of above of broken bits line and all outside the wall uses argillaceous brick build by laying bricks or stones to build. Side wall ply: Magnesia brick 690mm, argillaceous brick 114mm. End wall ply: Magnesia brick 920mm, argillaceous brick 114mm. Crust of large rectangle electric stove uses minute of field boarding (board is large 20 ~ 40mm) cooperate to rise with framework body of fixed build by laying bricks or stones, in recent years a few large electric stove are improve life of lining of position of broken bits line, use water to cover boarding, have boarding effect already, have the effect of water-cooling boiler setting again, see a table 1.
