Abstract
The utility model discloses a nodulation-free furnace roller of a roller-hearth type heat treatment furnace. The nodulation-free furnace roller comprises a shaft neck, wherein a first shaft neck and a second shaft neck are fixed with the two sides of a roller body respectively; a baffle is fixed at one end of the first shaft neck and one end of the second shaft neck respectively and is arranged in the roller body; the shaft neck is connected with the other end of the first shaft neck; the shaft neck is sleeved with an end cover; both the first shaft neck and the second shaft neck are filled with heat-resistant materials; a first furnace slag region is arranged outside the first shaft neck; a second furnace slag region is arranged outside the second shaft neck; a bearing seat is arranged on one side of the second furnace slag region and fixed with a bearing; a shaft coupler is connected with the bearing; a motor is connected with the shaft coupler; the roller body is made of ceramic fibers. According to the nodule-free furnace roller, the technical problem of an influence on the product quality caused by scratch of a heat treatment plate due to bulging and nodulation of the furnace roller is solved and the surface of the heat treatment plate is guaranteed to be not damaged.
Description
Technical field
The utility model relates to a kind of furnace roller, particularly relates to a kind of roller hearth heat-treated furnace without dross furnace roller.
Background technology
Roller hearth heat-treated furnace is unique industrial furnace that can carry out continuous heat treatment (quenching, normalizing, annealing, tempering, solid solution etc.) in metallurgy industry.The furnace roller of roller hearth heat-treated furnace adopts the furnace roller of roller hearth heat-treated furnace, though the body of roll adopts refractory alloy, at high temperature, surface oxidation still can produce bulge, dross.Bulge, dross scratch to heat treated plate surface, affect plate surface quality.To some, not allowing the special rolling-mill section of surface finish to demote uses or scraps, affecting the economic benefit of Heat Treatment Enterprises.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of roller hearth heat-treated furnace without dross furnace roller, and it solves in background technology because furnace roller bulge, dross scratch the technical problem that thermal treatment sheet material affects quality product.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of roller hearth heat-treated furnace is without dross furnace roller, it is characterized in that, it comprises axle journal, the first axle journal, the second axle journal, the body of roll, baffle plate, heat-stable material, bearing support, bearing, shaft coupling, motor, the first slag district, the second slag district, end cap, the first axle journal, the second axle journal is fixed with the both sides of the body of roll respectively, a baffle plate is separately fixed at one end of the first axle journal, one end of the second axle journal and be positioned at the body of roll, axle journal is connected with other one end of the first axle journal, end cap is enclosed within on axle journal, in the first axle journal and in the second axle journal, be all filled with heat-stable material, the first slag district is positioned at outside the first axle journal, the second slag district is positioned at outside the second axle journal, bearing seat is in a side in the second slag district and fix with bearing, shaft coupling is connected with bearing, motor is connected with shaft coupling, the material of the body of roll is made by ceramic fiber.
Preferably, the described body of roll be shaped as cylindric.
Preferably, the diameter of one end of described the first axle journal is greater than the diameter of the other end of the first axle journal, and the diameter of one end of the second axle journal is greater than the diameter of the other end of the second axle journal.
Preferably, described end cap and a buckle are fixed, and buckle is also fixed with the first slag district.
Positive progressive effect of the present utility model is: the body of roll plays the effect of support sheet material, does not directly contact sheet material.And contact with steel with cleaning, be not oxidized, without the ceramic fiber body of roll of scaling loss, thereby guarantee that thermal treatment plate surface does not damage.The utility model keeps non-water-cooled simultaneously, and not increasing stove energy consumption increases, and keeps the physical dimension of former furnace roller, can realize furnace roller of the present utility model in the situation that not transforming the former type of furnace, directly changes.
Accompanying drawing explanation
Fig. 1 is that a kind of roller hearth heat-treated furnace of the utility model is without the structural representation of dross furnace roller.
Embodiment
Below in conjunction with accompanying drawing, provide the utility model preferred embodiment, to describe the technical solution of the utility model in detail.
As shown in Figure 1, a kind of roller hearth heat-treated furnace of the utility model comprises axle journal 1 without dross furnace roller, the first axle journal 21, the second axle journal 22, the body of roll 3, baffle plate 4, heat-stable material 5, bearing support 6, bearing 7, shaft coupling 8, motor 9, the first slag district 101, the second slag district 102, end cap 11, the first axle journal 21, the second axle journal 22 is fixed with the both sides of the body of roll 3 respectively, a baffle plate 4 is separately fixed at one end of the first axle journal 21, one end of the second axle journal 22 and be positioned at the body of roll 3, axle journal 1 is connected with other one end of the first axle journal 21, end cap 11 is enclosed within on axle journal 1, in the first axle journal 21 with in the second axle journal 22, be all filled with heat-stable material 5, the first slag district 101 is positioned at outside the first axle journal 21, the second slag district 102 is positioned at outside the second axle journal 22, bearing support 6 is positioned at a side in the second slag district 102 and fixes with bearing 7, shaft coupling 8 is connected with bearing 7, motor 9 is connected with shaft coupling 8, the material of the body of roll 3 is made by ceramic fiber.Being shaped as of the body of roll 3 is cylindric, and convenient like this and the first axle journal, the second axle journal are fixed.The diameter of one end of the first axle journal 21 is greater than the diameter of the other end of the first axle journal 21, and the diameter of one end of the second axle journal 22 is greater than the diameter of the other end of the second axle journal 22, and the elements such as convenient like this and axle journal, bearing support are connected.End cap 11 and a buckle 12 are fixing, and buckle 12 is also fixing with the first slag district 101, end cap and axle journal can be fixed together better like this.
The body of roll plays the effect of support sheet material, does not directly contact sheet material.And contact with steel with cleaning, be not oxidized, without the ceramic fiber body of roll of scaling loss, thereby guarantee that thermal treatment plate surface does not damage.The utility model keeps non-water-cooled simultaneously, and not increasing stove energy consumption increases, and keeps the physical dimension of former furnace roller, can realize furnace roller of the present utility model in the situation that not transforming the former type of furnace, directly changes.
