The technical parameter of mine hot stove also is influence lining one of main factors of fireproof material life, 2 diameter of furnace casing of furnace of the electrode because of this reasonable configuration kiln furnace, kiln, voltage are exceedingly important.
1, extremely the influence of heart round diameter
Extremely heart round diameter is the craft parameter with important electric stove. If size is too small, extremely density of heart round power will be too big, high temperature heat although too center at extremely inside heart round area, make temperature exorbitant, erode hearth, use up fast, ; of lining loss of life if size is too large, extremely the heart is round power general on the low side, make bath brim temperature exorbitant, broken bits iron erodes aggravate to boiler setting, boiler setting attenuates, easy happening boiler setting is burned wear an accident, the life of lining can shorten likewise. Accordingly, appropriate extremely heart round diameter can be effective the with boiler setting temperature inside round area of control pole heart, reduce Yu Wen heating power to be mixed to hearth of boiler setting erode, this is the main factor that affects lining service life
2, the influence of furnace casing diameter
Furnace casing diameter also is the main craft parameter of electric stove. Choice of furnace casing parameter is logical, whether with extremely photograph of heart round parameter matchs, affect technical index of production not only, the service life that also affects lining if furnace casing diameter and extremely heart round diameter, extremely wall span and homogeneous phase of boiler setting ply match, criterion lining life can lengthen; accordingly conversely, if furnace casing diameter and extremely heart round diameter does not match, if furnace casing diameter is too big, waste fireproof material not only and the influence gives furnace; and if furnace casing diameter is too small, extremely wall span passes small or boiler setting is too unkind do not be able to bear or endure erode, lining life also will shorten accordingly, this is to create lining service life short important because of tired.
3, the 2 voltage influence to lining
2 voltage is electric stove another important craft parameter. Choose voltage 2 times to want with extremely photograph of heart round diameter matchs, ability prolongs lining life. Extremely when heart round diameter is certain, when use 2 voltage on the low side, electrode arc is short, insert below deep, distance hearth is close, bring about extremely the hearth temperature with heart corresponding circle is exorbitant, erode action to increase to the heat of hearth, make hearth is formed " boiler end account " and had used up fast conversely, hearth temperature is low, slag temperature is high, exorbitant temperature makes slag fluidity increases, to boiler setting erode aggravate, boiler setting attenuates, produce boiler setting extremely easily to burn wear an accident, influence lining life, because of breed of opposite certain smelt, 2 voltage is relatively stable, also be relatively stable to the influence of lining.
