Abstract
The invention provides an impoverishment electric stove single power transmission elevation temperature law, first, after electric stove electrode is located, the lifting operation are forbidden again; then slags are laid on the bottom floor of an electric stove chamber, an three-phase electrode is connected by steel bars, a backflow forms; finally cokes are laid in the interior of the chamber, specially the lower part of the electrode must be buried by the coke approximately 500-600 mm, then the power transmission may be carried on. The craft of the invention is simple, easy to operate; the elevation temperature heat source of the invention is in the center of a furnace body; the radiating heat spreads to the periphery uniformly; refractory bricks are heated evenly; and the elevation temperature cycle of the electric stove is short.
Description
Technical field:
The present invention relates to a kind of slag cleaning furnace once electricity-feeding temperature-raising method.
Background technology:
At present after large ore electrothermal stove, the slag cleaning furnace cold repair for the water evaporates in the refractory material in the body of heater is gone out, simultaneously also in order to ensure stove safety, assurance long service life, prevent that refractory brick Yin Wendu from raising suddenly and crack performance takes place, and all will formulate and carry out body of heater intensification plan.Body of heater intensification plan all is to utilize oil liquefaction vapour to add firewood or charcoal preheating baking 4-5 days usually, enter body of heater inside then and lay slag, coke, steel bar etc., final electrode send electricity, and this method operating environment is abominable, the intensification cycle is long, baking is inhomogeneous, and be full of cracks appears in refractory brick easily.
Summary of the invention:
Purpose of the present invention just provides a kind of slag cleaning furnace once electricity-feeding temperature-raising method.
Purpose of the present invention can be achieved through the following technical solutions:
At first, behind the electric furnace electrode location, forbid remaking descending operation; Lay slag at the electric stove hearth bottom then, three-phase electrode is connected, form and reflux with steel bar; To bury the about 500-600mm of electrode at burner hearth laid inside coke, particularly electrode bottom coke at last, next just can send.
Technology of the present invention is simple, and is easy to operate, and its intensification thermal source is at the body of heater center, and radiant heat is evenly diffusion towards periphery, and refractory brick is heated evenly, and the electric furnace intensification cycle is short.
