In-furnace water cooling partition capable of online mounting and manufacturing and mounting method of partition

Abstract

The invention relates to an in-furnace water cooling partition capable of online mounting. The partition is characterized by mainly comprising a partition steel structure and indefinite-form refractory materials. The inside of a hanging water tank is separated into a plurality of same water tank chambers along the length direction or forms one water tank chamber. An E-shaped water cooling pipeline is fixedly connected to the lower portion of each water tank chamber. The pipe openings on two sides of the water cooling pipeline are respectively connected and communicated with two ends of the corresponding water tank chamber. The middle of each water tank chamber is provided with a water tank water outlet. The indefinite-form refractory materials are simultaneously poured on the middle portion and lower portion of each water cooling pipeline and wrap each water cooling pipeline to form a rectangular partition body. A plurality of hanging steel beams and a pair of hanging earrings are fixed on the upper surface of the hanging water tank. The pair of hanging earrings are respectively located at two ends of the hanging water tank. The in-furnace water cooling partition is reasonable in structurally design, stable in performance, convenient in mounting and replacement, and capable of integrally assembled outside a furnace and online mounting and replacement.

Description

Technical field [0001] The invention relates to the technical field of a steel rolling heating furnace or a heat treatment furnace, and in particular to a water-cooled partition wall in a furnace that can be installed online, and a manufacturing and installation method thereof. Background technique [0002] Heating furnaces and heat treatment furnaces are heating equipment widely used in the steel rolling industry. The furnace body structure is mostly regular rectangle or ring-shaped end-to-end. The separation of various important temperature control sections and charging and discharging process furnace sections in the furnace and the furnace section atmosphere isolation mainly rely on partition walls, also known as "pressing down". [0003] According to the cooling method, the traditional partition wall is mainly divided into two types: no cooling and air cooling, and the structure is mostly arched or "V". In the process of heating furnace design and construction, the design of p...

Problems solved by technology

Reasons: First, the partition wall is the key equipment for the division of the heating furnace section, and its stable performance is an important guarantee for the normal production and operation of the heating furnace; secondly, the structural form of the traditional partition wall determines its high design requirements and difficult construction. The wall is a hanging device, and the arch or "V" shape is a special-shaped structure. The problem of uniform stress on the hanging and anchoring, the sealing and expansion absorption between the partition wall and the furnace body are all difficulties in design and construction; again, In the absence of water cooling or air cooling, the heat resistance load of the partition wall is large, and the phenomenon of expansion and cracking of the unshaped refractory material on the working surface often causes the partition wall to penetrate fire, and there is a risk of wall collapse in severe cases.
