Abstract
The utility model discloses a kind of roll head and neck makes annealing treatment separate type heater, including upper shell and lower shell, upper shell is cylindrical with lower shell synthesis one, and the height of upper shell is the 1/3 of lower shell, the upper shell is cavity, if being fixed with resistor group by bolt stem in lower shell, the upper shell, lower shell are fixed by cylindrical steel, and shaped steel outer layer is strengthened fixing by flange.Compared with conventional art, roll neck heater takes 1 to this utility model：3 height ratio design, main part are located at bottom, are evenly equipped with adding thermal resistance band, beneficial to the equilibrium of heat in heater chamber, as the roll neck position only to annealing carries out local heating, without whole roll is entered stove heat, energy consumption is substantially reduced, economic benefits.
Description
Technical field
This utility model belongs to mechanical forging field, and in particular to a kind of roll head and neck makes annealing treatment separate type heater.
Background technology
To advocate green energy conservation clean manufacturing, the repaired recycling of roll is more and more universal.For to roll itself
From the point of view of quality and safe handling, wherein repairing in the majority with the non-bearing rib head and neck of roll especially.Large scale, big thickness（It is monolateral
More than 5mm）The main flow repair mode taken at present of head and neck reparation remain as submerged-arc welding, welding stress is larger, submerged-arc welding work
Need surfacing part is carried out moving back stress process after end, and general mode is the side for taking whole roll to enter bench vehicle type electrical resistance furnace
Formula is first at the uniform velocity warming up to 420-450 DEG C with the speed of 15 DEG C/h or so completing, and is incubated 6-10h, and stove is cooled to less than 100 DEG C and goes out
Stove is air-cooled.Whole process is time-consuming very long, furnace processing time above a week.Existing resistance heating kiln high energy consumption；Operation
Rate is low；Annealing cycle is long, affects production.
The content of the invention
Goal of the invention：The purpose of this utility model is for the deficiencies in the prior art, there is provided a kind of roll head and neck annealing
Process separate type heater.
Technical scheme：In order to reach foregoing invention purpose, what this utility model was specifically performed by：A kind of roller head
Neck makes annealing treatment separate type heater, including upper shell and lower shell, and upper shell is cylindrical with lower shell synthesis one, and top cylinder
The height of body for lower shell 1/3, the upper shell are cavity, if being fixed with resistor group, institute by bolt stem in lower shell
State upper shell, lower shell to fix by cylindrical steel, shaped steel outer layer is strengthened fixing by flange.
Beneficial effect：Compared with conventional art, roll neck heater takes 1 to this utility model：3 height ratio design, it is main
Body portion is located at bottom, is evenly equipped with adding thermal resistance band, beneficial to the equilibrium of heat in heater chamber, due to roller only to annealing
Cervical region position carries out local heating, and without whole roll is entered stove heat, energy consumption is substantially reduced, economic benefits.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
A kind of roll head and neck annealing separate type heater as shown in Figure 1, including upper shell 1 and lower shell 2, top cylinder
Body 1 is 2-in-1 with lower shell cylindrical into one, and the height of upper shell 1 is the 1/3 of lower shell 2, and the upper shell 1 is cavity, under
If being fixed with resistor group 4 by bolt stem 3 in cylinder 2, the upper shell 1, lower shell 2 are fixed by cylindrical steel 5, type
5 outer layer of steel is strengthened fixing by flange 6.
