Abstract
The invention relates to an energy efficient fixture method for anchor nails. The method is as follows: welding an anchor L-shaped steel plate (2) on a furnace shell, fixing the anchor nails by anchor nuts before the installation of an anchor steel plate (5), and then installing the anchor steel plate (5) on the anchor L-shaped steel plate (2) through a bolt and nut fastener (3) to finish the installation of a row of anchor nails; installing the next row of anchor nails according to above steps until the whole furnace is filled up, and then installing refractory fibre (6) to realize that the refractory fibre (6) is fixed on the furnace wall (1) of a vertical continuous annealing furnace. In the invention, the carbon steel anchor L-shaped steel plate is adopted, and a carbon steel welding rod can be used for welding, thereby saving welding lost; only two connection points for a plurality of anchor nails are arranged on the furnace shell, thus reducing the number of a heat bridge, reducing heat loss and saving energy consumption; and the invention also has the advantages of saving labor cost, improving the fixing quality of the anchor nails and improving working efficiency.
Description
Technical field
The present invention relates to the refractory materials fixed network, particularly relate to a kind of energy-saving fixing means of anchor nails that is used for the vertical continuous annealing furnace refractory ceramic fibre.
2, the application of refractory ceramic fibre in vertical annealing furnace
Background technology
In the Large Scale and Continuous annealed wire, the annealing furnace that is disposed is generally vertical continuous annealing furnace, it mainly is made of preheating section, heating zone, slow cooling section, fast cold section, overaging section, cold section eventually, shrend, and its length generally can reach about 150 meters, highly reaches about 24 meters.Vertical continuous annealing furnace is mainly used in the rolling back recrystallization annealing of cold rolled strip, eliminates cold hardening, and the strip steel annealing volume of excellent performance, great surface quality is provided for building, household electrical appliances, automobile and other industries.
Continuous annealing line in process of production, need according to frequent conversion kind of the production program and specification, variant production kind annealing temperature requires different, become specification or become the stable state that can produce qualified product in the kind process and reach another kind of annealing curve rapidly from a kind of annealing curve stable state for reaching, this just requires annealing furnace to have good thermal response ability.
The vertical continuous annealing technology is because of output is big, the production kind obtains development at full speed entirely.In order to cut down the consumption of energy and to guarantee that good surface properties, the thermal insulation technology of annealing furnace are to cut down the consumption of energy and influence one of important factor of strip surface quality.
In the insulation design of vertical continuous annealing furnace, adopt refractory fibre usually as heat preserving and insulating material.Refractory fibre fixing added by anchor nails generally that this conventional fixed method of nut realizes: furnace shell is installed after check finishes, and beginning is rule on furnace shell, finds out the installation site of anchor nails, by special welding gun anchor nails directly is welded on the furnace shell then.
Traditional anchor nails consolidated form referring to Fig. 2, the steps include:
The first step, setting-out location on furnace wall steel plate 1 earlier;
Second step, adopt special-purpose anchoring welding gun that single-ended threaded anchor nails 11 is welded on the furnace wall steel plate 1, in filling whole stove, begin to install refractory fibre 6 then, and fix with middle card 7, anchoring nut 10, pad 9, interior lining panel 8 assemblies, realize with refractory fibre 6 be fixed on the furnace wall steel plate 1 of vertical continuous annealing furnace.
There is following problem in above-mentioned traditional anchor nails consolidated form:
1. cost height: because of anchor nails is a stainless steel, furnace shell is a carbon steel, and this anchor nails welding must be adopted stainless steel electrode.
2. poor welding quality: generally directly anchor nails is welded on the furnace shell at the scene by special welding gun.This Type of Welding is insecure, often just has a large amount of anchor nails to come off in the process of welding.
3. inefficiency: need spend great amount of manpower and time at the scene welds and handles the bad anchor nails of welding quality.
4. energy consumption height: because of anchor nails One's name is legion in the annealing furnace, form easily bigger " heat bridge ", calorific loss is very big.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of anchor nails energy-saving fixing means, so that solve the problem that traditional anchor nails consolidated form exists.
The technical scheme that the present invention solves its technical problem employing is: earlier anchoring L shaped steel plate is welded on the furnace shell, after before anchor plate is installed, just anchor nails being fixed by the anchoring nut, by the bolt and nut fastening piece anchor plate is installed on the anchoring L template then, anchor nails in a row has so just installed; According to above step next row's anchor nails is installed, in filling whole stove, refractory fibre is installed then, realize refractory fibre is fixed on the furnace wall steel plate of vertical continuous annealing furnace.
The present invention compares with traditional anchor nails consolidated form has following main beneficial effect:
One. adopt the anchoring L shaped steel plate of carbon steel material, its welding adopts Carbon Steel Covered Electrode to get final product, thereby saves welding cost.
They are two years old. and adopt anchoring L shaped steel plate to be welded on scheme on the furnace shell, be installed to again on the anchoring L shaped steel plate anchor plate just can be fixed anchor nails before installation by the anchoring nut after, thus raising anchor nails fixed mass.
They are three years old. and employing anchoring L shaped steel plate is welded on the scheme on the furnace shell, can make a plurality of anchor nails have only two tie points on furnace shell, has reduced the quantity of " heat bridge ", thereby has reduced calorific loss, energy efficient.
They are four years old. and only need a spot ofly manually just can install rapidly at the scene, and not need to handle the bad anchor nails installation quality of welding quality that exists in the prior art, thereby improve working efficiency and saved labour turnover.
They are five years old. owing to have above-mentioned plurality of advantages, use is worth promoting.
