A type of elliptical variable cross-section welding slag tank and its manufacturing method

Abstract

The invention provides a welded slag pot with a variable approximately-elliptical cross section. The welded slag pot with the variable approximately-elliptical cross section comprises a pot body, a pot bottom, a plurality of support assemblies and a plurality of supporting plate structures. The cross section of the pot body is approximately elliptical. The pot body is formed mainly by welding a front curved panel and a rear curved panel to a corresponding left cone frustum and a corresponding right cone frustum respectively. The lower end face of the pot body is welded to the pot bottom to form the pot body. The support assemblies are welded to the upper portion of the pot body. The supporting plate structures are welded to the lower portion of the pot body. A plurality of pot legs are welded to the lower surface of the pot bottom. The welded slag pot with the variable approximately-elliptical cross section is easy to manufacture, the volume of the welded slag pot can be maximized under the restraint of the factors such as limitation of field space, materials of the slag pot are saved, and the self weight of the slat pot is reduced; meanwhile, the tendency of replacing a cast slag pot by the welded slag pot can be expanded, and pollution is reduced. The invention further provides a manufacturing method of the welded slag pot with the variable approximately-elliptical cross section. When the welded slag pot with the variable approximately-elliptical cross section is manufactured through the manufacturing method, manufacturing is easier, and the quality of the slag pot is good.

Description

technical field [0001] The invention relates to a slag tank, in particular to an elliptical variable cross-section welded slag tank and a manufacturing method thereof. Background technique [0002] The slag tank is a container used to hold the high-temperature slag produced in the iron and steel smelting process; the slag tank is an important equipment for steel slag treatment in the metallurgical industry. [0003] Metallurgical enterprises in China and western developed countries use a large number of slag tanks. For a long time, slag tanks have been manufactured by casting methods. Casting can hardly avoid the discharge of a large amount of dust, waste gas, waste sand, and waste slag. The environment has caused huge pollution. [0004] With the development of science and technology, welding technology is becoming more and more mature. More and more slag tanks can be fabricated using welding techniques. Welded slag pots have gradually replaced cast slag pots. However, ...

AI Technical Summary

Problems solved by technology

However, when using welding technology to manufacture some slag tanks with special shapes, such as variable cross-section slag tanks, there are defects such as the construction site is limited by space and other factors, the volume of the slag tank cannot be maximized, and the amount of slag tank materials is large.
