Molten steel tank edge masonry construction without gland plate and construction method of molten steel tank edge masonry construction

Abstract

The invention provides a molten steel tank edge masonry construction without a gland plate and a construction method of the molten steel tank edge masonry construction. The molten steel tank edge masonry construction without the gland plate comprises a ring of tank edge bricks constructed to the uppermost end of a tank wall working layer, a plurality of supporting anchoring parts distributed on the inner wall of a tank edge steel shell and a tank edge casting material, the tank edge bricks are special-shaped bricks with the high inner portions and the low outer portions, the top faces of the tank edge bricks are lower than the tank edge of the steel shell, and the side, facing the steel shell, of each tank edge brick is an inclined face. When special masonry is carried out on the construction, the ring of tank edge bricks constructed to the uppermost end of the masonry tank wall working layer, then the multiple supporting anchoring parts are welded to the tank edge part of the steel shell, then film hanging, tank edge casting material pouring, vibration, maintenance and baking are carried out in sequence to form the complete tank edge part, and the multiple supporting anchoring parts are completely embedded through the tank edge part. The molten steel tank edge masonry construction is simple in structure and convenient to construct, the construction quality is controlled more easily, the durability and the using effect of a molten steel tank are improved, and safety factors are increased.

Description

technical field [0001] The invention relates to a steel molten steel tank for holding and pouring molten steel in a steelmaking plant, in particular to a molten steel tank edge masonry structure without a gland plate and a construction method. technical background [0002] The molten steel tank is a container that holds molten steel during the steelmaking process and is used for refining or casting steel. It has the functions of holding, refining, transshipment, and heat preservation. The smelted molten steel is stored in molten steel tanks, transported to corresponding stations, and used for pouring or pouring after refining according to needs; forming blanks, and then processed into various steel products. [0003] During the storage of molten steel or the refining process of the molten steel tank, the refractory material of the tank body is affected by a series of effects such as high temperature, gravity impact, chemical erosion, internal stress caused by rapid temperat...

Problems solved by technology

[0005] The existing tank edge construction method can not meet the requirements of use well, and its main defects are as follows: (1) Due to the cover plate, refractory materials need to be placed between the bricks and the gland plate, which will bring problems to the construction. It is inconvenient and the construction quality is not easy to control; (2) in the process of use, because the steel slag hanging on the edge of the tank is often cleaned with a "hook", the edge of the tank is easily damaged; (3) because the gland steel plate is directly connected with the Therefore, the gland plate is easily damaged, and the effect of the gland is not very good; (4) There are easy to produce annular joints between bricks and bulk refractory materials, bricks and bricks-causing steel seepage, which brings safety problems.
