Abstract
The utility model relates to a kind of high radiant heat and utilizes metal sintering bed of material product, comprises the radiant heat absorbent layer be made up of exotic material, and described radiant heat absorbent layer aims at sinter bed upper surface, and described radiant heat absorbent layer top is provided with air intake.The utility model absorbs the photothermal heat-absorbing material layer of sinter bed by arranging, the radiant heat that heat-absorbing material layer absorbs is returned the bed of material by the gas outlet simultaneously by aiming at sinter bed, reduce sintering solid fuel consumption, simultaneously because described radiant heat reclaims product, bed of material air inlet is more evenly distributed, thus improves productivity of sinter and sinter quality.
Description
Technical field
The utility model relates to a kind of high radiation heat utilization product, particularly relates to a kind of high radiant heat and utilizes metal sintering bed of material product.
Background technology
In current industrial production, energy resource consumption is huge, and resource pressure is very large, and the application provides a kind of high radiation heat utilization product, by high radiating surface coating, reduces the consumption of heat, improves energy utilization rate.Generally, a certain proportion of solid fuel is added in sinter mixture, compound is auxiliary on sintering pallet, chassis travels forward with certain speed, is lighted by solid fuel in compound top layer by ignition furnace, under the effect of material layer lower part suction pressure, outside air enters the bed of material, solid fuel in the bed of material is burnt downwards gradually, and when the bed of material arrives chassis terminal, the bed of material also completes sintering process simultaneously.
Burning is participated in because sintering process needs outside air to enter the bed of material, so general sintering machine is after the bed of material has gone out ignition furnace, the bed of material outwardly boundary's environment opens wide, so that air enters the bed of material, but its shortcoming existed is: after the bed of material goes out ignition furnace, high temperature top layer is with radiation mode outwardly loses heat, enter the bed of material without preheating cool ambient air simultaneously, cooling effect is risen to the bed of material, therefore in order to make sintering carry out smoothly, ignition furnace ignition energy must be increased and increase more solid fuel in compound, so just cause the increase of sintering process gas and solid fuel consumption, if ignition furnace ignition energy is excessive on the other hand, top layer can be caused to superfuse and to affect bed permeability, thus affect sintering quality.
Existing corrective measure is: after ignition furnace, set up air bells cap, enters sinter bed, plays insulation effect to the bed of material, be called hot air sintering technology by extraction loop cold-hot wind.But the ring cold-hot wind dustiness that hot gas sintering extracts is comparatively large, causes air exhauster faults frequent, in fact, much takes the sintering machine of hot air sintering technology, take out hot-air system and all cannot normally run, air exhauster also needs to consume electric energy simultaneously, reduces the consumption of the energy.
Summary of the invention
The utility model, in order to the defect that solves above-mentioned prior art and exist and deficiency, provides one and can reclaim bed of material radiant heat and return the bed of material, reduce sintering solid fuel consumption, thus the sinter bed radiant heat improving sinter quality utilizes.
The technical solution of the utility model: a kind of high radiant heat utilizes metal sintering bed of material product, comprises the radiant heat absorbent layer be made up of exotic material, and described radiant heat absorbent layer aims at sinter bed upper surface, and described radiant heat absorbent layer top is provided with air intake.
Radiant heat absorbent layer can also be stored by efficient absorption sinter bed radiant heat, when outside air is by radiant heat recovery layer, again carry heat is returned sinter bed.For the air capacity by radiant heat absorbent layer, the negative pressure that air is produced by sintering machine itself sucks, and when air is by radiant heat recovery layer, the radiant heat it reclaimed returns the bed of material.
High radiant heat utilizes that sinter bed product can automatically absorb heat, heat release, and by the air of preheating through high radiation heat utilization product, by carry heat material-returning layer, bed of material radiation heat loss is dropped to minimum, high radiation heat utilization product does not need additionally to consume electric energy.
Preferably, described air intake is provided with air inflow control valve.
High radiant heat utilize sinter bed product make to enter the bed of material air-distribution evenly, prevent the bed of material local raw burn phenomenon because air inlet inequality causes, improve productivity of sinter and sinter quality.
The utility model absorbs the photothermal heat-absorbing material layer of sinter bed by arranging, the radiant heat that heat-absorbing material layer absorbs is returned the bed of material by the gas outlet simultaneously by aiming at sinter bed, reduce sintering solid fuel consumption, simultaneously due to described high radiation heat utilization product, bed of material air inlet is more evenly distributed, thus improves productivity of sinter and sinter quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1. sintering machines, 2. sinter bed in figure, 3. ignition furnace body of heater, 4. igniter burner, 5. high radiant heat utilizes sinter bed product, 6. air intake, 7. radiant heat absorbent layer, 8. air inflow control valve.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but is not the restriction to the utility model protection domain.
As shown in Figure 1, a kind of sintering feed floor height radiant heat utilizes product, comprises radiant heat absorbent layer 7, and radiant heat absorbent layer 7 aims at sinter bed 2 upper surface, and radiant heat absorbent layer 7 top is provided with air intake 6, and air intake 6 is provided with air inflow control valve 8.
Radiant heat absorbent layer 7 is made up of exotic material, can also be stored by efficient absorption sinter bed radiant heat, and when outside air is by radiant heat absorbent layer, again carry heat is returned sinter bed, sinter bed radiation heat utilization product does not need additionally to consume electric energy.Radiant heat absorbent layer 7 can automatically absorb heat, heat release, by the air of preheating through radiation heat utilization product, by carry heat material-returning layer, bed of material radiation heat loss is dropped to minimum.In addition, the material of described radiant heat absorbent layer 7 includes zirconia.
The utility model absorbs the photothermal heat-absorbing material layer of sinter bed by arranging, the radiant heat that heat-absorbing material layer absorbs is returned the bed of material by the gas outlet simultaneously by aiming at sinter bed, reduce sintering solid fuel consumption, simultaneously due to described high radiation heat utilization product, bed of material air inlet is more evenly distributed, thus improves productivity of sinter and sinter quality.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structure change made under enlightenment of the present utility model, and every have identical or akin technical scheme with the utility model, all belongs to protection domain of the present utility model.
