Abstract
The utility model relates to an indirect cooling furnace roller device, which is characterized in that the indirect cooling furnace roller device consists of a furnace roller, an indirect cooling central water-cooling pipe, a rotary joint, a metallic hose and a bearing. The indirect cooling furnace roller device has the advantages that the inside of the 'central water-cooling pipe' is cooled through a little water, the cooling water and the 'central water-cooling pipe' do not directly contact the furnace roller and can only generate radioactive heat transfer, and the amount of the cooling water is small and is generally about one tenth of a direct cooling furnace roller structure, thereby the heat taken away by the cooling water can be greatly reduced; the temperature borne by the furnace roller can be properly reduced so as to maintain the surface temperature of the furnace roller between 1,000 and 1,100 DEG C; general furnace roller materials on the prior market can be used, thereby the production cost is greatly reduced; the possibility of generation of local low temperature of a workpiece to be processed is greatly reduced; and the novel indirect cooling furnace roller device has been thrown into actual application, and the use effects all meet the design requirements, and the operation of the furnace roller is stable and failure-free.
Description
(1) technical field:
The utility model belongs to a kind of heating unit, particularly a kind of indirect cooled furnace roller device.
(2) background technology:
Roller bottom type heating, heat treatment furnace are a kind of at key processing equipment that iron and steel/coloured/mechanical industry is generally used.In the production practice of roller bottom type heating, heat treatment furnace, heated workpiece is placed on the furnace roller, heat in stove, transmit according to the speed and the temperature of technique initialization.Heating or thermal treatment process temperature are generally between 800 ℃-1250 ℃.Therefore furnace roller (being generally hollow) is the most crucial parts of this kind equipment.
In the practice, furnace roller is divided into " dried roller " and " wet roller " two kinds.
So-called " dried roller " is meant that furnace roller does not need that water cools off, body of roll material is used the heat-resistant high alloy steel manufacturing.Its maximum operation (service) temperature is general≤and 1100 ℃.The advantage of dried roller is energy-conservation (not must water-cooled), and shortcoming is more than 1100 ℃ the time, to need the high refractory alloy that uses price extremely expensive for product thermal treatment process temperature requirement.Because therefore cost factor has often limited the application in the actual production.
And " wet roller " is meant that furnace roller directly uses water cooling (water coolant and tube wall transmission of heat by convection), body of roll material can use the ordinary low-alloy steel manufacturing.When it mainly was used in technological temperature above 1100 ℃, maximum operation (service) temperature can reach 1300 ℃ (regulating the cooling water flow sizes).The advantage of wet roller is that with low cost being convenient to made, shortcoming is to take away a large amount of heats and cause the energy consumption height owing to water coolant, more fatal in addition shortcoming is, because the body of roll temperature of direct water-cooling very low (general≤300 ℃), can cause to be heated workpiece and to produce topical hypothermia's (being commonly called as " black seal "), thereby have a strong impact on quality product with the furnace roller contact site.
How to realize satisfying the use temperature greater than 1100 ℃, reduce the high energy consumption that causes because of water-cooled simultaneously, can eliminate or alleviate " black seal " again, this is a puzzlement world industry stove industry problem for many years.
(3) summary of the invention:
The purpose of this utility model is to design a kind of indirect cooled furnace roller device, and the advantage of comprehensive above-mentioned two kinds of furnace rollers overcomes its deficiency.
The technical solution of the utility model: a kind of indirect cooled furnace roller device is characterized in that it is to be made of furnace roller, indirect type cooling center water cooling tube, swivel joint, metallic hose and bearing; Said furnace roller inside is equipped with the indirect type cooling center water cooling tube that an inside is connected with a small amount of water coolant, and indirect type cooling center water cooling tube outside surface and furnace roller internal surface keep the certain interval amount; Furnace roller both sides adjacent end head is equipped with bearing, and the furnace roller end is equipped with swivel joint, and metallic hose is arranged on the swivel joint, and metallic hose is communicated with indirect type cooling center water cooling tube; The furnace roller frame is contained between the furnace wall of two sides.
The above-mentioned said swivel joint that is connected with metallic hose is installed in the one or both ends of furnace roller.
On the above-mentioned said swivel joint that is installed in furnace roller one end a straight-through mouth of pipe and a side siphunculus mouth are arranged, two mouths of pipe of this end connect water inlet metallic hose and water outlet metallic hose respectively.
On the above-mentioned said swivel joint that is installed in the furnace roller two ends a straight-through mouth of pipe is arranged respectively respectively, two mouths of pipe at these two ends connect water inlet metallic hose and water outlet metallic hose respectively.
Principle of work of the present utility model: furnace roller carries out heat exchange through the water coolant of radiation, convection current and heat transfer by conduction and center water cooling tube, reduces the furnace roller surface temperature.Swivel joint and metallic hose are responsible for water coolant is imported and derives; Water inlet, one at one end brings out in the indirect cooled furnace roller device of water, and water coolant imports indirect type cooling center water cooling tube through the water inlet metallic hose, behind the radiation heat transfer, derives through the other end water outlet metallic hose; In the indirect cooled furnace roller device of same end Inlet and outlet water, water coolant imports indirect type cooling center water cooling tube through the water inlet metallic hose, behind the radiation heat transfer, derives through the same water metallic hose that brings out.Inside and outside the water cooling tube of center special device is housed, causing only needs a small amount of water coolant just can satisfy the cooling requirement.Simultaneously, the design of pipe core makes things convenient for the cleaning of incrustation scale.
Superiority of the present utility model is: 1, " center water cooling tube " is inner cools off by less water, and water coolant does not directly contact with furnace roller with " center cooling tube ", radiative transfer can only take place each other, cooling water amount is little, be generally about 1/10th of direct cool furnace roll structure, thereby significantly reduce the heat (the direct water-cooling structure can not arbitrarily reduce the water yield, otherwise can cause the water coolant vaporization) that water coolant is taken away; 2, the temperature that reduction furnace roller that can be suitable bears remains between 1000 ℃-1100 ℃ the furnace roller surface temperature; 3, can use general in the market furnace roller material, greatly reduce production cost; 4, greatly reduce to make and be heated the possibility that workpiece produces topical hypothermia's (black seal); 5, novel indirect water-cooling furnace roller device has dropped into practical application, and result of use all satisfies designing requirement, stable, the trouble free of furnace roller.
