Abstract
The utility model relates to a device for controlling the concentricity of a roller hole brick of a solid melting furnace. The device comprises a locating steel pipe and two annular steel plates, wherein the two annular steel plates are respectively sleeved and fixed on the outer walls of the two ends of the locating steel pipe, a distance between the two annular steel plates is equal to the inner diameter of a solid melting furnace casing, and the diameter of each annular steel plate is equal to the roller hole diameter of the solid melting furnace casing. The device has the advantages that the manufacture is simple; the concentricity of the roller hole brick can be accurately controlled, thereby facilitating the installation of the roller hole brick; the construction efficiency is improved.
Description
Technical field
The utility model belongs to solid smelting furnace field, especially a kind of device of controlling solid smelting furnace roller hole brick concentricity.
Background technology
The roller-hearth heating treatment funaces roller hole brick using is at present mostly casting material prefabricated, required precision is very high, when construction, use the method for copying relief, bracing wire to control concentricity and linearity, in installing, use, overhaul at furnace roller, expose series of problems: 1. to exceed requirement excessive due to roller hole brick installation accuracy, when being installed, roller cannot adjust precision, roller hole and roll shaft decentraction, and roller hole is uneven, not point-blank, affect roller installation accuracy, roll shaft and roller hole brick are rubbed mutually, roll shaft and brick gap, roller hole are 5mm; 2. there is crack and splash swollenly rubbing mutually with roller in roller hole brick in use, and impact is produced normally; 3. in maintenance, more precision is difficult to consistent with the roller hole brick control of not changing during the brick of roll change hole.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of device of controlling solid smelting furnace roller hole brick concentricity is provided, and this device is made simple, and control roll hole brick concentricity, facilitates the installation of roller hole brick accurately, improves efficiency of construction.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of device of controlling solid smelting furnace roller hole brick concentricity, its device comprises positioning steel tube and two blocks of annular steel plates, two blocks of annular steel plates are set with and are fixed on the outer wall of positioning steel tube two ends, distance between two blocks of annular steel plates equals solid smelting furnace furnace shell internal diameter, and the diameter of annular steel plate equals solid smelting furnace furnace shell roller bore dia.
And described annular steel plate thickness is 16～20mm.
And described positioning steel tube diameter is 50～80mm.
Advantage of the present utility model and beneficial effect are:
The device of the solid smelting furnace roller of this control hole brick concentricity, its device comprises positioning steel tube and two blocks of annular steel plates, two blocks of annular steel plates are set with and are fixed on the outer wall of positioning steel tube two ends, distance between two blocks of annular steel plates equals solid smelting furnace furnace shell internal diameter, the diameter of annular steel plate equals solid smelting furnace furnace shell roller bore dia, and the utility model is made simple, accurately control roll hole brick concentricity, facilitate the installation of roller hole brick, improve efficiency of construction.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of device of controlling solid smelting furnace roller hole brick concentricity, its device comprises positioning steel tube 2 and two blocks of annular steel plates 1, two blocks of annular steel plates are set with and are fixed on the outer wall of positioning steel tube two ends, distance between two blocks of annular steel plates equals solid smelting furnace furnace shell internal diameter, the diameter of annular steel plate equals solid smelting furnace furnace shell roller bore dia, annular steel plate thickness is 16～20mm, and positioning steel tube diameter is 50～80mm.The allowance control of annular steel plate thickness and positioning steel tube diameter is within ± 0.5mm.
When the utility model is installed for roller hole brick, to install for one group that roller hole brick is relative simultaneously, the annular steel plate at the utility model two ends is placed in the roller hole of solid smelting furnace furnace shell both sides, measuring roller hole is to the distance of positioning steel tube outer wall, at least 4 points, till the distance of adjusting to each point equates, carry out next group roller hole brick again and install, circulation successively, until install, after roller hole concentricity, linearity and absolute altitude are adjusted, can carry out the resistance to unit construction in brick top, roller hole.
The utility model has guaranteed the installation accuracy of roller hole brick, guaranteed that roller hole and roll shaft are concentric, guaranteed roller hole point-blank, thereby can guarantee the installation accuracy of roller, in use roller hole brick does not occur to rub mutually with roller, guaranteed normal production, in maintenance, more precision is consistent with the roller brick of not changing during the brick of roll change hole.
