Background technology
Along with the continuous progress of society and the continuous development of science and technology, energy shortage becomes the significant problem of the serious puzzlement national economic development, this forces industrial sector to continually develop and utilize new forms of energy on the one hand, on the other hand, people adopt conservation measures, both constantly employed new technology on the production technique, novel process updates old production technique and working condition, constantly uses novel material to be able to energy-conservation simultaneously again in realizing energy-conservation process.Self-evident, the development and utilization of new forms of energy and employing conservation measures all be unable to do without material science and technology development of technology and development.
The application of refractory fibre in vertical annealing furnace: 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.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.Connect and move back 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.In vertical annealing furnace, adopt refractory fibre usually as heat preserving and insulating material.Because of refractory fibre proportion is little, heat storage capacity is little, and is stronger to the thermal response ability of annealing furnace, so the production of frequent change description is had very strong adaptability.
Fixing of refractory ceramic fibre: in the Large Scale and Continuous annealed wire, the annealing furnace that is disposed is generally vertical annealing furnace.Annealing furnace 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.Annealing furnace generally adopts refractory fibre (ceramic fiber) as the heat-insulation and heat-preservation material, and its fixing means is generally fixed by the method that anchor nails adds the anchoring nut, and as shown in Figure 1, refractory materials fixes by anchor nails conventional fixed form.In the annealing furnace installation process, the installation method of anchor nails conventional fixed form generally adopts special welding gun directly to be welded in anchor nails on the furnace shell, its installation sequence is generally furnace shell and installs after check finishes, beginning is rule on furnace shell, find out the installation site of anchor nails, by special welding gun anchor nails is welded on the furnace shell then.
Summary of the invention
The purpose of this utility model is to provide the stationary installation of refractory fibre in a kind of vertical annealing furnace, high efficiency when this stationary installation is used.
To achieve these goals, technical scheme that the utility model adopts is: the stationary installation of refractory fibre in the vertical annealing furnace, card, pad, anchoring nut, anchor nails in the middle of it comprises; Be provided with refractory fibre between the furnace wall steel plate of vertical annealing furnace and the interior lining panel of vertical annealing furnace, interior lining panel is provided with the anchor nails hole, the inner of anchor nails is positioned at the furnace wall steel plate place of vertical annealing furnace, the outer end of anchor nails is positioned at outside the interior lining panel after passing anchor nails hole on refractory fibre, the interior lining panel, the outer end of anchor nails is rotary with the anchoring nut, be with pad on the anchor nails between anchoring nut and the interior lining panel, card has a middle card on the anchor nails, and middle card is between the interior lining panel of the furnace wall steel plate of vertical annealing furnace and vertical annealing furnace; It is characterized in that: it also comprises set screw nut, and set screw nut is welded on the furnace wall steel plate of vertical annealing furnace, and the inner end of anchor nails is threaded, and the inner end of anchor nails is threaded with set screw nut.
The utlity model has following characteristics:
1, high efficiency: the consolidated form that anchor nails is traditional need spend great amount of manpower and time at the scene and weld and handle the bad anchor nails of welding quality.Stationary installation of the present utility model only need a spot ofly manually just can install high efficiency rapidly at the scene.
2, welding quality is good: anchor nails traditional welding form generally directly is welded on anchor nails the furnace wall steel plate of vertical annealing furnace 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.Stationary installation of the present utility model can be produced in manufacturing set screw nut is welded on the furnace shell, only threaded anchor nails need be tightened at the scene to get final product.
3, because of anchor nails is the Stainless Steel material, the furnace wall steel plate of vertical annealing furnace is a carbon steel, and general anchor nails welding must be adopted the Stainless Steel welding rod.The material of the set screw nut of stationary installation of the present utility model is a carbon steel material, and the welding of set screw nut adopts Carbon Steel Covered Electrode to get final product.
The beneficial effects of the utility model are: high efficiency (reduce labour intensity and save a large amount of construction and installation time), save welding cost, and improve the welding anchoring quality.
