Abstract
A heat treatment furnace applied in the resurfacing welding of the huge roll comprises a roll bracket, a furnace and a worktable at the top of the furnace. The huge roll is arranged on the roll bracket; the furnace is composed of a top-left section, a bottom-left section, a top-right section and a bottom-right section, the four sections of the furnace is incorporated to become a sealing cylindrical cavity. The utility model is simple and compact in structure; during the resurfacing welding, the huge roll is welded from the top to the bottom, and the huge roll is only lifted twice; the simple procedure greatly reduces the intensity of the labor; therefore, the utility model is applicable in the resurfacing welding of the huge roll in the small and medium enterprises.
Description
One., technical field
The utility model relates to a kind of Equipment for Heating Processing, particularly a kind of heat treatment furnace that is applicable to that the large-scale roller built-up welding is produced.
Two., background technology
Roller-way is the equipment unit that iron and steel enterprise widely applies, the economic worth that built-up welding is repaired is huge, especially large-scale roller is as the major equipment of hot rolling production, cost an arm and a leg, the economic benefit of repairing is very remarkable, but its bead-welding technology is strict, wants strict control interlayer temperature postwelding also need carry out destressing thermal treatment when needing preheating, built-up welding before the built-up welding, so a lot of built-up welding factories are overlaying welding machine tool and the large-scale heat treatment furnaces of using when the built-up welding large-scale roller more, the hold facility place is many, investment is big.In addition, preheating, built-up welding and three operations of thermal treatment independently cause the lifting before and after the built-up welding frequent, and general 1 large-scale roller of built-up welding need lift 4 times at least, as considering interlayer thermal treatment and other Special Circumstances, the lifting number of times will be more, labour intensity height, inefficiency.
Three, summary of the invention
The utility model technical issues that need to address are: lift in the roller-way built-up welding repair process frequently in order to solve, and problems such as inefficiency, the utility model provides a kind of heat treatment furnace that preheating, built-up welding and thermal treatment are one that collects.
The technical solution of the utility model is: a kind of large-scale roller built-up welding heat treatment furnace, comprise body of heater, it is characterized in that also including turning rolls, furnace roof workplatform, turning rolls is positioned at the both sides, front and back of body of heater, roller-way is shelved on the turning rolls, and the roll surface of roller-way and part roll neck place in the furnace chamber.Body of heater mainly is made up of body of heater upper left quarter, body of heater lower left quarter, body of heater upper right quarter, body of heater right lower quadrant, furnace chamber, body of heater upper left quarter and body of heater upper right quarter have big chassis chassis structure, can be before and after the outside track walking deciliter, body of heater lower left quarter and body of heater right lower quadrant have little chassis chassis structure, can be before and after the inner orbit walking deciliter, body of heater lower left quarter and body of heater upper left quarter and body of heater right lower quadrant and body of heater upper right quarter are " drawer type " embedded structure, and body of heater upper left quarter, body of heater lower left quarter, body of heater upper right quarter, body of heater right lower quadrant are incorporated into the cylindrical furnace chamber that surrounds sealing together.The furnace roof workplatform divides left platform, right platform two portions, be one with body of heater upper left quarter, the weldering of body of heater upper right quarter respectively, the built-up welding groove is offered at furnace roof workplatform center-line joint position, and it is chimeric that bell and built-up welding groove form " bottle stopper formula ", and welding set is installed on the furnace roof workplatform.
The utlity model has entire fibre lining, the electrically heated of far-infrared ceramic sheet, multiple spot independence temperature control, roomy furnace roof workplatform, compact construction, equipment and take up an area of less, save advantages such as investment, during built-up welding, no matter whether carry out interlayer thermal treatment, large-scale roller from the built-up welding of reaching the standard grade to rolling off the production line, front and back only need lift 2 times, operation is easy, is fit to very much sme development large-scale roller built-up welding industry.
