Making technology of novel steel structure door

Abstract

The invention provides a making technology of a novel steel structure door. The technology is characterized in that a production line mainly includes a sintering furnace from a sintering plant, a iron making blast furnace from an iron making plant, a steel making furnace from a steel making plant, and casting and steel rolling devices from a casting and steel rolling workshop; and the technology comprises the following steps: screening iron ores and iron sand ores, sintering high quality raw materials in the sintering furnace from the sintering plant until the raw materials are spherical in shape, mixing the obtained spheres with coke, putting the obtained mixture in the iron making blast furnace from the iron making plant, burning to form molten iron, sending the molten iron to the steel making plant, smelting to make steel, sending molten steel from the steel making plant to the casting and steel rolling workshop, carrying out steel forming, and cooling. Compared with the prior art, the technology has the advantages of simple operation, and realization of light weight, high strength, good ductility, good shock resistance, fire resistance and sound insulation of the novel steel structure door.

Description

technical field [0001] The invention belongs to the field of access control design and manufacture, and in particular relates to a manufacturing process of a novel steel structure door. Background technique [0002] Steel structures have the characteristics of light weight, high strength, good ductility, and strong seismic performance. At present, steel structures are increasingly used in industrial and mining enterprises, large buildings, and public facilities. [0003] At present, metal doors made of general steel in houses and buildings generally require fire-proof and heat-insulating effects. The inside of the door leaf is filled with fire-resistant materials and compacted. The density is too high, which causes the door body to be too heavy. The body is not closed tightly, which seriously affects the use. Contents of the invention [0004] The purpose of the present invention is to provide a manufacturing process which is easy to operate and can realize light weight, ...
