Abstract
The utility model discloses a combined high-temperature liquid metal container ladle cover, and relates to the field of metallurgical production technologies. The combined high-temperature liquid metal container ladle cover consists of movable steel frames, refractory bricks and a pull rod, wherein the steel frames are filled with the refractory bricks, horizontal through holes are formed on the refractory bricks, the pull rod penetrates an upper steel frame and a lower the steel frame for clamping the refractory bricks with the through holes, and a spring is arranged in the pull rod. Under the action of the pull rod, the spring can be ensured to produce the proper pre-tightening force through an adjusting nut, so as to enable the refractory bricks to be kept in close contact, ease the internal stress of the refractory bricks due to the temperature variation, prevent refractory materials from producing cracks and shedding due to continuous temperature variation during the repeated use, improve the thermal shock resistance of the ladle cover, simultaneously facilitate the replacement of the refractory bricks, be convenient to carry out overhaul, replacement and production, greatly prolong the service life of the high-temperature liquid metal container ladle cover and save the cost.
Description
Technical field
The utility model belongs to the metallurgical production technical field, relates to a kind of combined high temperature fluent metal container bag clad.
Background technology
Because large high-temperature liquid metal vessels bag clad area is bigger, and, be furnished with stopper hole and burner hole on the clad, therefore, the clad bulk strength is difficult to guarantee that clad castable refractory cover layer peels off seriously, clad metal structure frame is ablated, and has restricted the raising in service life of middle clad.The high temperature fluent metal container bag clad of metallurgical production continuous casting technology field use at present is the version that different shape holdfast knotting refractory material is set up in whole steel construction below, though improvement is in various degree arranged on concrete structure, but service life is not long, does not all break away from big, several fatal problems such as refractory material comes off soon, the easy scaling loss of steel construction of whole steel construction distortion.
Chinese patent literature CN2900519 discloses a kind of cathode baking furnace bell metal framework structure, and it is fixedlyed connected with lower frame by upper frame; Lower frame is a triangle, and a groove is arranged on hypotenuse, and the refractory material skew block is embedded in the groove.This structure can not be moved refractory material arch springing when expanding and cool off of bell, guarantees the service life of bell.
Chinese patent literature CN1200966 discloses a kind of steel mill and has produced the tundish cover process with waste molten steel.It is by making base, dry by the fire tire, casting and form.Making base is to adopt steel plate by middle clad shape fabricating frame, smears refractory brick along the scuncheon pendulum and forms heat insulation layer, and the U type tire of being with heat insulation layer is made in last claying material levelling to U type annular distance it on.
Above-mentioned two kinds of disclosed bells of technical scheme or clad all are to increase refractory brick in the part of metal framework, can not solve still that refractory material temperature in use repeatedly constantly changes and crackle comes off, the easy scaling loss of formed steel construction, the whole problem that becomes of clad.
Summary of the invention
The utility model is at high temperature fluent metal container bag clad bulk deformation in the metallurgical production production process is big, refractory material comes off soon, the problem of the easy scaling loss of steel construction, provide a kind of not only high temperature resistant but also make things convenient for the combined high temperature fluent metal container bag clad of making, to solve a short difficult problem of high temperature fluent metal container bag clad life-span.
The technical solution adopted in the utility model is as follows: combined high temperature fluent metal container bag clad, form by steel frame, refractory brick and pull bar, it is characterized in that: fill by refractory brick between the steel frame, horizontal through hole is set on the refractory brick, through hole and bottom steel frame that pull bar passes on upper steel framework, the refractory brick clamp upper and lower steel frame, be provided with spring in the pull bar, spring is regulated degree of tightness by the bolt of pull bar upper end.
Above-mentioned refractory brick can be clay matter, mullite, quartzy siliceous or high alumina matter.
Two horizontal through hole are set on above-mentioned every block of refractory brick at least.
Because steel frame is in the tundish bag along last, directly do not contact high temperature fluent metal, can not deform.The temperature that combined high temperature fluent metal container bag clad is born is more than 1100 ℃, and refractory brick can not be out of shape and subsides under this temperature.The clad thermal shock resistance further improves, to reach the purpose of using repeatedly.
The beneficial effects of the utility model are: the utility model is under the effect of pull bar, guarantee that by adjusting nut spring has suitable pretightning force, automatically regulate the spacing of each steel frame, make and keep closely contact between the refractory brick, alleviate refractory brick because of the internal stress that variations in temperature produces, prevent that refractory material temperature in use repeatedly from constantly changing and crackle comes off, improve the thermal shock resistance of clad, be convenient to the replacing of refractory brick simultaneously, accomplish that the maintenance replacing is easy to make.Big, the difficult problems such as refractory material comes off soon, the easy scaling loss of steel construction of high temperature fluent metal container bag clad bulk deformation have been solved effectively, prolonged high temperature fluent metal container bag clad service life greatly, experimental results show that high temperature fluent metal container bag clad of combined long-life of this kind is 5 times of the whole knotting of steel construction refractory material clad service life, saves a large amount of costs.

The specific embodiment
Combined high temperature fluent metal container bag clad, form by steel frame, refractory brick and pull bar, fill by schamotte brick between the steel frame, two horizontal through hole are set on every block of refractory brick, pull bar passes through hole and the steel frame clamping up and down of bottom steel frame on upper steel framework, the refractory brick, be provided with spring in the pull bar, spring is regulated degree of tightness by the bolt of pull bar upper end.Guarantee the pretightning force that suits by adjusting spring, regulate the spacing of upper and lower steel frame, make and keep closely contact between the refractory brick, alleviate the internal stress that refractory brick produces because of variations in temperature, prevent refractory material temperature in use repeatedly from constantly changing and crackle comes off, improve the thermal shock resistance of clad, be convenient to the replacing of refractory brick simultaneously, accomplish that the maintenance replacing is easy to make.Solved effectively that bulk deformation in the Ferrous Metallurgy continuous casting system liquid receptacle bag clad production production process is big, refractory material comes off soon, the problem of the easy scaling loss of steel construction, saved a large amount of maintenance costs, prolong high temperature fluent metal container bag clad service life, saved a large amount of costs.
Refractory brick can also be used mullite, quartzy siliceous or high-alumina refractory brick; Through hole on the refractory brick also can be more than two.
