Description

The net prestressed crucible of metal

Technical field

The utility model is related to crucible technique field, more particularly to a kind of net prestressed crucible of metal.

Background technology

Crucible in use, often because human users' reason causes that crucible wall is subject to power from inside to outside, such as Instrument is tapped, material expanded by heating to be melted is ejected etc., ultimately results in crucible wall longitudinally through formula cracking, failure.While earthenware High/low temperature alternation easily causes failure caused by crucible wall Transverse Cracks repeatedly during crucible use.

Utility model content

The purpose of this utility model is to provide a kind of net prestressed crucible of metal, to solve above-mentioned technical problem.

The utility model embodiment provides a kind of net prestressed crucible of metal, including pot and is wrapped in the outer of the pot The prestressing force wire netting fixed on wall and with the pot, the shape of the prestressing force wire netting and the pot shape phase Match somebody with somebody, the prestressing force wire netting is woven on the outer wall of the pot along the outer wall of the pot by multiple wires and is formed, The matched coefficients of thermal expansion of the thermal coefficient of expansion of the wire and the pot.

Further, the prestressing force wire netting has multiple octagon mesh, and the multiple octagon mesh is in Ranks are arranged, and two adjacent octagon mesh are shared on one side, and that two adjacent octagon mesh are shared While being formed by two wire hinge joints.

Further, the prestressing force wire netting also includes multiple square mesh, is expert at adjacent upwards with row upwards Four octagon mesh between formed a square mesh.

Further, the material of the pot is including at least in graphite, carborundum, corundum, aluminum oxide, clay and mullite One kind.

Further, the cross section of the wire is circular or rectangle, and the diameter range of the wire is in 0.5-4 milli Rice.

Further, the diameter range of the wire is at 1-2 millimeters.

Further, the thermal coefficient of expansion of the wire is (2~6) x10-6/Co.

Further, the model nickel-base alloy Incoloy903 of the wire.

Further, the shape of the multiple mesh on the prestressing force wire netting in regular hexagon shape, square shape or Person's equilateral triangle shape.

The beneficial effects of the utility model are：

The net prestressed crucible of metal of the present utility model weaves prestressing force wire netting by pot outer wall, forms one in advance Stress cage structure, makes pot radial and axial all in pretension and the state being pressurized.Longitudinally opened so as to significantly reduce pot The possibility with Transverse Cracks is split, the applicable working condition of pot has significantly been expanded.

Brief description of the drawings

Fig. 1 is the structural representation of the net prestressed crucible of metal of the utility model embodiment.

Specific embodiment

It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer Type implementation method is further described.

Fig. 1, a kind of net prestressed crucible of metal of the utility model embodiment offer, including pot 1 are provided and are wrapped in Prestressing force wire netting 2 on the outer wall of pot 1, shape and the shape of pot 1 of prestressing force wire netting 2 match, prestressing force metal Net 2 is woven on the outer wall of pot 1 along the outer wall of pot 1 by multiple wires 3 and is formed.

In the present embodiment, prestressing force wire netting 2 has multiple octagon mesh 4, and multiple octagon mesh 4 are in row Shared one of row arrangement, the shared one side of two adjacent octagon mesh 4, and two adjacent octagon mesh 4 Bar side is formed by the hinge joint of two one metal wire 3.It is arranged such energy on the multiple wires 3 that can ensure to constitute prestressing force wire netting 2 Enough produce enough tension force so that when pot 1 is subject to power from inside to outside, the tension force that wire 3 is provided can offset pot 1 and receive The injury power from inside to outside for arriving, and then ensure that pot 1 will not be destroyed, while enabling prestressing force wire netting 2 by gold The tension force for belonging to silk 3 is fixed in pot 1.Multiple mesh forms in other embodiment, prestressing force wire netting 2 are not limited to just Octagon, or square, equilateral triangle or regular hexagon etc..

In the present embodiment, prestressing force wire netting 2 also includes multiple square mesh 5, be expert at upwards with arrange upward phase An above-mentioned square mesh 4 is formed between four adjacent octagon mesh 4.

In the present embodiment, the material of pot 1 comprises at least graphite, carborundum, corundum, aluminum oxide, clay and mullite In one kind.

In the present embodiment, the cross section of wire 3 is circle, and the diameter range of wire 3 is in 0.5-4 millimeters, preferred value It is 1-2 millimeters.In other embodiments, wire 3 can also be in flat sheet, i.e. the cross section of wire 3 is rectangular.

In the present embodiment, the thermal coefficient of expansion of wire 3 is (2~6) x10-6/Co, substantially with the heat of pot 1 of crucible The coefficient of expansion is matched, and is used when crucible is raised to high-temperature region from room temperature, and wire need to be remained compared with hightension, if wire Much larger than the thermal coefficient of expansion of crucible, then during crucible is raised to high temperature from room temperature, wire is no longer tensioned thermal coefficient of expansion, Crucible wall is also no longer influenced by the effect of pretension compression.Further, in the present embodiment, the model of wire 3 is Ni-based Alloy Incoloy903.

The beneficial effects of the utility model are：

The net prestressed crucible of metal of the present utility model weaves prestressing force wire netting 2 by the outer wall of pot 1, forms one Prestressing force cage structure, makes pot 1 radial and axial all in pretension and the state being pressurized.Indulged so as to significantly reduce pot 1 To cracking and the possibility of Transverse Cracks, the applicable working condition of pot 1 has significantly been expanded.

Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all in this practicality Within new spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in guarantor of the present utility model Within the scope of shield.
