Description
Technical field
The present invention relates to glassmaking arts, and in particular to the double C plot structures of float glass lehr.
Background technique
Final sheet is widely used, and the height of yield rate depends on the size of residual stress.Stress be usually by
Caused by non-uniform cooling condition, glass tape is placed under the conditions of suitable temperature and is heat-treated, can answered by
Power is reduced or is eliminated.And annealing kiln is the key equipment of annealing process in glass production link, is mainly characterized by glass
It is cooling according to certain annealing rule, to eliminate internal stress and optical heterogeneity in glass tape, inside stabilized glass
Structure.
Traditional glass annealing is theoretical generally using " fast, slow, fast " annealing cooling technique, i.e., in the area soaking zone A and cooling
The temperature drop speed in the area section C can be fast with respect to for the temperature drop speed in the area annealing section B.The heat exchange mode in the area cooling section C is spoke
Penetrate heat transfer, intensity of cooling is big, it is general by suitably reducing shell insulation layer thickness to reinforce heat dissipation, increase cooling air quantity and simultaneously
Increase cooler area to strengthen heat dissipation.By heat dissipation formula Q=G × c × Δ T of glass it is found that glass heat dissipation capacity and the nature of glass
It is proportional to measure G, specific heat capacity c, inlet and outlet temperature difference T.With day fusing amount, the i.e. increase of glass quality G, the cooling of annealing kiln is negative
Lotus Q is consequently increased.Glass tape uses adverse current radiation heat transfer in the area cooling section C and cooling medium, and feature is cold in high temperature section
But medium and the glass temperature difference are relatively small, and heat exchange efficiency is lower.
With the development in top-grade building glass market, with the obvious advantage, such as the yield rate of large-tonnage floatation glass production line.
And on the floatation glass production line greater than 1000MT/D or even 1200MT/D, the structure in traditional area cooling section C can not close
Expected cooling effect is obtained in the annealing kiln length of reason, eventually leads to that glass annealing quality is poor, and residual stress is big, easily fried plate etc.
Unstable production.
To solve the above-mentioned problems, we are made that a series of improvement.

It is theoretical generally using " fast, slow, fast " annealing cooling technique based on traditional glass annealing, to the glass of same thickness
The cooling velocity of band 600, the area cooling section C can be more appropriate than annealed zone fast.Traditional design of single area C and raising cooling
The means of efficiency can not still solve the problems, such as that the area C front cooling efficiency is low.How the " slow, fast " cooling of the area traditional cooling zone C
Status is promoted to the cooling of " fast, fast " and is expected, we devise a kind of this double area cooling section C adverse current annealing of float glass lehr
Technique.
Its principle of the invention is that entire cooling section is made of the cooling zone of two independent controls, and respectively first dissipates
Hot-zone 1 and the second radiating area 2.By counterflow heat exchange mean temperature difference formula Δ T=(Δ Tmax-ΔTmin)/(ln(ΔTmax/ΔTmin)
It is found that when the first radiating area 1 and the second radiating area 2 become the cooling section with independent adverse current cool wind process, so that the
Heat exchange in 2nd area of one radiating area 1 and the second radiating area, all has biggish heat transfer temperature difference Δ T, the area entire cooling section C have compared with
The big Average heat transfer temperature difference.Again by Newtonian Cooling formula Q=α × F × (tGlass-tIt is situated between) it is found that due to glass tape 600 and cooling medium
Heat transfer temperature difference increase, enhance heat transfer effect, thus entire cooling section has biggish cooling capacity, it is ensured that meets glass tape
The ability of 600 annealing demands." fastly, the entire area process section A, the area B, the first radiating area 1 and the second radiating area 2 collectively form one
Slowly, complete annealing operation system fastly, fastly ", substantially increases the cooling efficiency and annealing quality of glass tape 600, it is ensured that steady
Fixed production.
Concrete analysis, it is high that present invention is generally directed to day fusing amounts, the fast super-tonnage floatation glass production line of pull speed,
The cooling efficiency for making a concrete analysis of the area cooling zone C front and back section, fundamentally improves the cooling efficiency of the area cooling zone C entirety and is designed to
Two-region adverse current annealed structure collectively constitutes the area A, the area B, the first radiating area 1 and the second radiating area 2 with the area AB and collectively forms one
The annealing operation system of " fast, slow, fast, fast ".
As shown in Figure 1, the first radiating area 1 and the second radiating area 2 that double C plot structures are made of two cold wind structures, pass through
Hot-air in cooler after heat exchange is aspirated discharge by blower 100, and cold air enters from the first upper end cooling wind of cooler
The 210, first lower end cooling air inlet 310 of mouth, the second upper end cooling air inlet 410 and the sucking of the second lower end cooling air inlet 510,
This is also referred to as the indirect cooling of cold wind suction-type.
The first radiating area 1 in this structure, the cold air t for cooler of entering is sucked from ambient air naturallyJie 1, compare
In the temperature of glass tape 600, the temperature difference t of medium temperature and glass tape 600Glass-tJie 1, by Newtonian Cooling formula Q=α × F ×
(tGlass-tIt is situated between) known to: biggish heat transfer temperature difference increases the heat dissipation capacity Q of glass tape 600, improves cooling efficiency.
It is illustrated in figure 2 the area conventional design list C counterflow configuration, equally by cold air inlet and front end under the plate upper plate of end
Air outlet and high-temperature blower common combination formed an open cooling system.In the front half section cooler in this structure
Medium temperature tJie 2It has been much larger than by heat exchange from ambient air and has entered air temperature naturally, it can thus be concluded that (tGlass-tJie 2) compared with
It is small.Heat transfer temperature difference is smaller, and the heat dissipation capacity Q for leading to glass tape is also smaller, and heat exchange efficiency is low.
As shown in figure 3, curve 1 is 600 surface temperature of double areas cooling section C glass tape；Curve 2 is traditional structure list cooling section
600 surface temperature of the area C glass tape；Curve 3,4 is respectively double cooling sections the first radiating area 1 and the second radiating area 2 of the invention
Cooling wind temperature rise curve；Curve 5 is the cooling wind temperature rise curve in the area single cooling section C.
In summary analyze: the double area the C annealing process of the present invention increase the temperature difference Δ of medium temperature and glass tape 600
T, so that increase glass tape 600 distributes heat, so that the area cooling section C has a biggish cooling capacity, expected from realization
The annealing process system of " fast, fast ".Solve day melt it is high, pull amount is big in the case where the area C cooling capacity insufficient lack
It falls into, meets the annealing process demand of large-tonnage production line.
A specific embodiment of the invention is illustrated above, but the present invention is not limited thereto, without departing from
Spirit of the invention, the present invention can also have various change.
