Abstract
The utility model discloses an energy-saving liner of a heating furnace, which comprises a heat insulating layer clung to the inner wall of a furnace body, a heat preservation layer and a working layer, wherein the heat preservation layer is a light refractory brick building layer, refractory bricks are made of a refractory material with density of 1.5g/cm<3> and a thermal conductivity coefficient of 0.35w/m.k at (350+/-10) DEG C, each refractory brick is internally provided with a horizontal pore duct and a vertical pore duct which are communicated with each other, the horizontal pore duct penetrates through the upper surface and the lower surface of the brick body, and the vertical pore duct penetrates through the two side surfaces of the brick body. The working layer is made of cellucotton. The energy-saving liner has the beneficial effects that the heat preservation layer is built by the light refractory bricks, the pore ducts are communicated in the heat preservation layer, so that the heat preservation layer has a good heat insulation effect, the temperature on the surface of the furnace body can be lowered to be 20-30 DEG C, the heat radiation of the furnace body can be effectively blocked, energy resources are saved, the refractory bricks are light in weight, the weight of the furnace body can be lightened, and the resource consumption is small.
Description
Technical field
The utility model relates to a kind of reheating furnace energy-saving liner.
Background technology
Heating furnace is the equipment with material or workpiece heating; By the thermal source division fuel heating furnace, resistance-heated furnace, induction heater, microwave oven etc. are arranged, it is widely used in many industry fields such as oil, chemical industry, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, material, light industry, daily use chemicals, pharmacy.Now general heating furnace furnace lining thickness is generally at 650 ~ 800mm, and furnace wall is thick, and materials are many, and consumption of natural resource is many; Body of heater appearance temperature is generally at 80 ~ 120 ℃, the integral heat insulation weak effect of furnace wall; The basis is thick and heavy, and expense is high.
The utility model content
In order to overcome above-mentioned defective, the utility model provides a kind of reheating furnace energy-saving liner, and good heat preservation performance, resource consumption be few, save construction cost, reduce fuel consumption.
To achieve these goals; The technical scheme of the utility model is: a kind of reheating furnace energy-saving liner; Comprise heat insulation layer, heat-insulation layer and the working lining of being close to inboard wall of furnace body, described heat-insulation layer is that light fire brick is built layer by laying bricks or stones, and described light fire brick uses density to be 1.5g/cm
3, being 0.35w/m.k at 350 ± 10 ℃ of following thermal conductivity factors, refractory material is processed; Horizontal duct that described light fire brick set inside is communicated with each other and vertical duct; Described interconnection connects two side surfaces of brick body, and described vertical duct connects the upper and lower surfaces of brick body.
Further, described working lining is built by laying bricks or stones with cellucotton and is formed.
The beneficial effect of the utility model is: because heat-insulation layer adopts light fire brick to process, inside also has the duct of mutual conduction to communicate, so heat-insulation layer has good heat insulation and preservation effect; The body of heater surface temperature can be reduced to 20 ~ 30 ℃; Can effectively stop the heat radiation of body of heater, energy savings, and also refractory brick is in light weight; Can alleviate body of heater weight, resource consumption is few.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structure for amplifying sketch map of heat-insulation layer light fire brick.
The specific embodiment
Below in conjunction with specific embodiment the utility model is done further explanation.
As depicted in figs. 1 and 2, the reheating furnace energy-saving liner of the utility model comprises heat insulation layer 2, heat-insulation layer 3 and the working lining 4 of being close to inboard wall of furnace body 1, and described working lining 4 usefulness cellucottons are built by laying bricks or stones and formed.Described heat-insulation layer 3 is built layer by laying bricks or stones for light fire brick 5, and described light fire brick 5 uses density to be 1.5g/cm
3, being 0.35w/m.k at 350 ± 10 ℃ of following thermal conductivity factors, refractory material is processed; Horizontal duct 7 that described light fire brick 5 set inside are communicated with each other and vertical duct 6; Described interconnection 7 connects two end surfaces of brick body, and described vertical duct 6 connects the upper and lower surfaces of brick body.
The technical scheme of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical scheme of the utility model all falls within the protection domain of the utility model.
