Abstract
The invention discloses a high-strength high-temperature-resistant furnace bottom roller; the high-strength high-temperature-resistant furnace bottom roller comprises a roll cylinder, a roll neck and a roll head; the roll head is arranged at two ends of the roll cylinder; the roll neck is fixedly connected between the roll cylinder and the roll head; the roll head is inserted into the end part of the roll neck, so that the roll head and the roll neck are matched and fixedly connected; a clapboard is arranged at the joint of the roll cylinder and the roll neck; a closed cavity is formed among the clapboard, the end part of the roll head and the inner hole of the roll neck; a thermal insulation material is filled in the cavity, so that a thermal insulation structure is formed; the high-strength high-temperature-resistant furnace bottom roller disclosed by the invention is further characterized in that two locating pin shafts penetrating through the matched part of the roll head and the roll neck in the radial direction are arranged at the matched part of the roll head and the roll neck; a part of one locating pin shaft passes through another locating pin shaft; and a high-temperature-resistant oxidized wear-resistant coating is arranged on the outer wall of the roll cylinder. According to the invention, the capability of transferring heat from the roll cylinder to a roll shaft is low; the working conditions of a bearing are obviously improved; the connection part of the roll head and the roll neck is high in strength; and the high-strength high-temperature-resistant furnace bottom roller is high-temperature-resistant, oxidization-resistant and wear-resistant.
Description
Technical field
The present invention relates to equipment for Heating Processing, particularly relate to a kind of furnace bottom roll.
Background technology
Furnace bottom roll is located in solution heat treatment furnace for transmitting the steel bar plate of heat-treating, to realize continuous heat treatment technological process, high temperature section furnace bottom roll is in 1000 ~ 1200 DEG C of temperature ranges and operation under the oxidative environment of open firing, and these furnace bottom rolls must keep the ability of transmission high temperature slab in long time continuous working.The furnace bottom roll of prior art comprises roller, roll neck, roller head, and roller head is arranged on roller two ends, and roll neck is fixedly connected between roller, roller head; Produce a large amount of heats in furnace bottom roll working process, in these heats, have many being delivered on roller head, cause roller head head bearing temperature to raise, worsen bearing working condition.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of can significantly reduction by the thermal heat transfer capability of roller to roll shaft, obviously improve the high-strength high temperature-resistant furnace bottom roll of bearing working condition.
The present invention is achieved through the following technical solutions technical object.
High-strength high temperature-resistant furnace bottom roll, comprises roller, roll neck, roller head; Described roller head is arranged on roller two ends, and roll neck is fixedly connected between roller, roller head; Described roller head inserts roll neck end, is formed and coordinates and be fixedly connected with; Its improvements are: described roller and roll neck junction are provided with dividing plate; Described dividing plate, form airtight cavity between roller cephalic par and roll neck endoporus, filling with insulation material in cavity, form heat insulation structural.
In said structure, described roller head, roll neck matching part are provided with the alignment pin that two radial directions run through roller head, roll neck matching part, and an alignment pin part wherein runs through another root alignment pin.
In said structure, described roller outer wall is provided with resistance to high temperature oxidation wear-resistant coating.
In said structure, described resistance to high temperature oxidation wear-resistant coating is MCrAlY coating.
The present invention compared with prior art, has following positively effect:
1. be provided with heat insulation structural in the cavity in roll neck, significantly reduce by the thermal heat transfer capability of roller to roller head, bearing working condition is obviously improved.
2. roller head, roll neck matching part are provided with the alignment pin that two radial directions run through roller head, roll neck matching part, and an alignment pin part wherein runs through another root alignment pin, such alignment pin difficult drop-off, and roller head, roll neck connect reliable; Alignment pin runs through roller head, roll neck matching part significantly improves roller head, roll neck strength of joint.
3. roller outer wall is provided with resistance to high temperature oxidation wear-resistant coating, can significantly improve resistance to high temperature oxidation of the present invention, abrasion resistance properties.
