Building and supporting method for semiring brick on hoogoven's warm-air duct inside lining

Abstract

The invention relates to a method for supporting lining upper semiring masonry of hoogoven type warm-air duct, comprising the steps that bricking is carried out from external ring to internal ring, hidden construction is changed into open-type construction, and thin bamboo strips and assorted boards are utilized to temporarily support the masonry during bricking up light bricks and heavy bricks; wherein, two ends of the boards are put on the lining lower semiring of the duct, the upper ends of the thin bamboo strips are utilized to prop the upper semiring masonry being bricked up, the lower ends of the thin bamboo strips are exerted on the boards and prevented from sliding by the transverse parting strips on the boards, and the thin bamboo strips are taken down after the slurry is dried or the upper semiring is closed; and the thin bamboo strips and the boards are dismounted after the bricking is finished. The invention replaces the traditional support method by wooden arch stuffing to support the lining upper semiring masonry by the thin bamboo strips and the boards, thereby not only being convenient for construction but also good for improving masonry quality of lining upper semiring bricks of the duct.

Description

technical field [0001] The invention relates to the inner lining construction of the hot air pipeline, in particular to a hogovin type hot air pipeline lining upper half-ring brick masonry support method which introduces Holland hogovin technology. Background technique [0002] The lining of the hot blast pipe is not only a refractory container for conveying hot air to the blast furnace during the production process of the hot blast stove, but also a carrier for conducting heat. The lining brick of the hot air duct is mainly composed of two parts: one part is the material that constitutes the non-working surface of the lining of the hot air duct, such as lightweight brick (insulation brick); the other part is the material that directly forms the working surface of the hot air duct lining, such as heavy Quality bricks (refractory bricks). The domestic traditional construction method of pipeline lining is to support wooden arch tires as a support, first build the inner ring o...

AI Technical Summary

Problems solved by technology

The domestic traditional construction method of pipeline lining is to support wooden arch tires as a support, first build the inner ring of heavy bricks from the inside to the outside, and build the outer ring of light bricks layer by layer. Therefore, the light brick masonry can only be built in narrow The method of stuffing bricks in the seam makes it difficult to grasp the processing size of the bricks, and it is difficult to guarantee the quality of the masonry. Often, the inner lining of the upper part of the pipe collapses or the inner lining brick of the upper part of the pipe falls off, causing the pipe shell to burn red

Moreover, bricks and mortars of various specifications are mixed together, and it is easy to use them incorrectly.

The design of the Hogovin-style hot air pipeline is designed to prolong the service life of the pipeline. It is required that each ring should be self-contained when working. Guaranteed to affect the service life of the pipeline
