Abstract
A molten steel smelting tundish cover plate comprises two side cover plates (7) and an intermediate cover plate (8); the plate body (1) of the cover plate is provided with an opening (2); a guard ring (3) made of fire-resistant fiber composite material is arranged at the opening (2); and the fire-resistant fiber composite material (3) is located in the plate body (1). The utility model overcomes the disadvantages that the existing tundish cover plate has the weakened welding intensity at a high temperature and can easily cause thermal expansion effect due to temperature changes, so that the steel plate is easy to deform and damage at the opening position. The molten steel smelting tundish cover plate is provided with a guard ring made of fire-resistant fiber composite material is arranged at the opening and can withstand greater thermal deformation; besides, the cover plate is simple to produce and easy to use.
Description
Technical field
The utility model relates to a kind of molten steel and smelts the tundish cover plate.
Background technology
In the steel smelting procedure, molten steel is changed over to tundish a period of time, to obtain suitable temperature (cooling), enters down the road flow process again to crystallize into base, the easy deformation damage under the molten steel baking for a long time of middle clad.Because the tapping of clad (being used for adding trace element or other material to molten steel) internal and external temperature is inconsistent, thermal stress is bigger.And guard ring and the former cause of clad body are welded herein, and at high temperature, the intensity of welding weakens.The heat expansion effect that is subjected to variations in temperature again and causes, at this moment place, hole steel plate is easy to deformed damaged.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned existing disadvantages of background technology part, and provides a kind of molten steel to smelt the tundish cover plate.
The purpose of this utility model reaches by following measure: molten steel is smelted the tundish cover plate, it comprises two side cover plates and inter panel, on the plate body of cover plate perforate is arranged, it is characterized in that the guard ring of described tapping for being made by the refractory fibre composite, described refractory fibre composite is positioned at plate body.
In technique scheme, described guard ring is fixed on the anchor studs at steel plate two ends and is distributed in steel plate refractory fibre composite all around and formed by the steel plate that is positioned at the middle part.
In technique scheme, described anchor studs is Y shape or V-arrangement.
In technique scheme, described inter panel is made up of two monomer cover plates, and semicircle opening guard ring is arranged on two monomer cover plates.
1., product is made up of four plate cover plates the utility model molten steel is smelted the tundish cover plate and had following advantage:, inter panel is divided into two from tapping, can reduce the thermal deformation of mid portion.2., the tapping of cover plate all is equipped with the guard ring that the refractory fibre composite is made, and can bear bigger thermal deformation.3. water time greater than 50 service life, more than 50 heats.Than existing product, increase service life about 5 times.4. it is simple, easy to use that the utility model molten steel is smelted the manufacturing of tundish cover plate.
Description of drawings
Fig. 1 smelts tundish structure of cover plate vertical view for the utility model molten steel.
Fig. 2 is the A-A cut-away view of Fig. 1.
The specific embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not constitute to qualification of the present utility model, only do for example.Simultaneously by illustrating that advantage of the present utility model will become clear more and understanding easily.
Consult accompanying drawing as can be known: the utility model molten steel is smelted the tundish cover plate, it comprises two side cover plates 7 and inter panel 8, on the plate body 1 of cover plate perforate 2 is arranged, the guard ring 3 of described perforate 2 places for making by the refractory fibre composite, described refractory fibre composite 3 is positioned at plate body 1 (plate body 1 outer surface has laterally or reinforcement longitudinally, and this structure is all arranged on the existing cover plate).Guard ring 3 is fixed on the anchor studs 5 at steel plate 4 two ends and is distributed in steel plate 4 refractory fibre composite 3 all around and formed by the steel plate 4 that is positioned at the middle part.Anchor studs 5 is Y shape or V-arrangement (also can be other shape).Inter panel 8 is made up of two monomer cover plates, and semicircle opening guard ring 3 is arranged on two monomer cover plates.
Claims (4)
