Abstract
The utility model relates to a novel water cooled furnace cover which comprises a cover body and a heat insulation layer, wherein the heat insulation layer is made of fireproofing material, the heat insulation layer is arranged in the cover body, air discharge holes are respectively arranged in the top part and the side wall of the cover body, and air vent holes are arranged in the side wall of the heat insulation layer. The novel water cooled furnace cover has simple structure and long service life, can timely discharge air, and is beneficial to stable and smooth production.
Description
Technical field
The utility model relates to a kind of steelmaking equipment, particularly relates to a kind of novel water cooled cover.
Background technology
The LF method is one of present most widely used furnace outer refining technology, by electric arc heated, make operations such as high basicity reducing slag, deoxidation alloying and Argon stirring, molten steel is carried out the control of temperature and composition, can also play the effect of coordinating first furnace and conticaster operation rhythm of production.As one of capital equipment of LF refining furnace, water cooled cover mainly is made of two parts, and a part is to adopt the steel construction piece of solid matter tubular structure, and another part is the refractory material of the inner knotting of steel construction.The problem that exists is that the gas that forms between the refractory material of steel construction and knotting can't be discharged at present, and the back gas that is heated expands, and causes the refractory material of knotting to separate with steel construction piece, causes refractory material to come off.The material phenomenon always appears collapsing in the refractory material that the bell of newly reaching the standard grade is tied a knot in use for some time, coming off of refractory material influenced the service life of bell on the one hand, the refractory material that comes off on the other hand falls in the ladle, the burn and scald evil that molten steel splashes and also causes the flushing and casting personnel easily.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, the novel water cooled cover of long service life.
In order to address the above problem, the utility model by the following technical solutions:
A kind of novel water cooled cover comprises lid and thermal insulation layer, and thermal insulation layer adopts refractory material to make, and thermal insulation layer is arranged in the lid, is respectively equipped with steam vent on lid top and the sidewall, and the thermal insulation layer sidewall is provided with passage, and steam vent and passage are staggered.
Compared with prior art, the beneficial effects of the utility model are:
All be provided with pore on the utility model lid and its inner refractory material, can discharge the gas that forms between lid and the refractory material effectively, prevent that refractory material from coming off, not only prolonged the service life of water cooled cover, also avoided the phenomenon that comes off and cause molten steel to splash owing to refractory material, prevent to scald the operating personnel, improved the performance of enterprises, reduced the security incident rate.
