Abstract
The utility model discloses a heating furnace for steel rolling, which comprises furnace bottom, a furnace roof, side walls, a furnace chamber, a chimney flue and a fire barrier inside the furnace chamber. The fire barrier is arranged at the lower part of the furnace chamber, and is vertically and fixedly connected with the furnace bottom; the fire barrier is rectangular in shape; the edges of the two sides of the fire barrier are tightly connected with the side walls; and smoke through-holes are formed at the upper part of the wall body of the fire barrier. According to the utility model, the smoke through-holes are formed on the fire barrier, so that not only smooth smoke discharging is ensured, but also the heating efficiency of the heating furnace is indirectly improved at the same time.
Description
Technical field
The utility model relates to and belongs to the steelmaking equipment technical field, particularly the process furnace used of a kind of steel rolling.
Background technology
at present, the process furnace of Steel Mill in use, the problem that occurs is that the burn with anger phenomenon of smoldering of stove tail chimney is serious, and the cigarette temperature is higher, in stove, heat insulation effect is poor, the way of conventional enterprise is firebreak to be set reduce the heat insulation effect that the flue gas tapping temperature improves stove in burner hearth, Chinese patent for example, patent announcement number: CN201605302, patent name is process furnace, firebreak is set has solved in theory above problem, yet the non-constant of smoke discharging effect after often finding firebreak is set in the use procedure of reality, flue gas is subject to the obstruct of firebreak in burner hearth, rolling is difficult to discharge in burner hearth, should this greatly reduce heating efficiency in burner hearth,
The utility model content
The purpose of this utility model is to be the deficiency that solves the problems of the technologies described above, the process furnace that provides a kind of steel rolling to use, and it is simple in structure, and price is low, and improves the heating efficiency of process furnace.
The utility model is the deficiency that solves the problems of the technologies described above, the technical scheme that adopts is: the process furnace that a kind of steel rolling is used, comprise furnace bottom, furnace roof, sidewall, burner hearth, flue and be arranged on the interior firebreak of burner hearth, firebreak is positioned at the bottom of burner hearth, be fixedly connected with furnace bottom is vertical, described firebreak is shaped as rectangle, and the dual-side of firebreak is along closely being connected with sidewall, is provided with exhaust hole on the body of wall top of firebreak.
The utility model, the exhaust hole on described firebreak is located on the same line, the plane parallel at this straight line and furnace bottom place.
The utility model, described exhaust hole be shaped as any one in rectangle, square or circle.
The utility model, the distance on described exhaust hole and firebreak between the edge is 35-55
㎜。
The beneficial effects of the utility model:
The utility model guarantees not only that by exhaust hole is set smoke evacuation is smooth and easy, has improved the heating efficiency of process furnace simultaneously indirectly on firebreak.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is along the structure sectional view of A in Fig. 1-A line.
Mark in figure: 1, burner hearth, 2, firebreak, 201, exhaust hole, 3, furnace bottom, 4, flue, 5, steel billet, 6, furnace roof, 7, sidewall.
Embodiment
as shown in the figure, the process furnace that a kind of steel rolling is used, comprise furnace bottom 3, furnace roof 6, sidewall 7, burner hearth 1, flue 4 and the firebreak 2 that is arranged in burner hearth 1, firebreak 2 is positioned at the bottom of burner hearth 1, be fixedly connected with furnace bottom 3 is vertical, described firebreak 2 is shaped as rectangle, the dual-side of firebreak 2 is along closely being connected with sidewall 7, the dual-side that is to say firebreak 2 along and sidewall 7 between seamless, guarantee that internal temperature runs off slow, when process furnace does not have outside heat supply, firebreak is as the radiant heating source of steel billet, improve heating efficiency, body of wall top at firebreak 2 is provided with exhaust hole 201, the utility model is by arranging exhaust hole on firebreak, guarantee that not only smoke evacuation is smooth and easy, indirectly improved simultaneously the heating efficiency of Steel In Reheating Furnace base 5.
In order further to optimize this scheme, the exhaust hole 201 on described firebreak 2 is located on the same line, the plane parallel at this straight line and furnace bottom 3 places; Exhaust hole 201 be shaped as any one in rectangle, square or circle; Distance on described exhaust hole 201 and firebreak 2 between the edge is 35-55 ㎜, and it is 38 ㎜ that the best arranges distance.
