Give priority to with the development of pouring and fireproof material, developed low cement, high density to spend fireproof material, apply extensively at bag of chamfer of blast furnace taphole, steel, intermediate bag and RH to wait, pushed steely trade the indeterminate form of fireproof material changes a technology.

Integrated media reported on June 21, before, the fireproof data that steel-making place uses is given priority to with firebrick all the time, but the technology that needs adroitness as a result of bricklaying operation, together with builds the problem such as the age ageing of furnace jockey in recent years, the automation that because this uses the indeterminate form of fireproof material,changes a technology to realize the operation that build furnace and economic labor force already made main task. Recently, give priority to with the development of pouring and fireproof material, developed low cement, high density to spend fireproof material, apply extensively at bag of chamfer of blast furnace taphole, steel, intermediate bag and RH to wait, pushed steely trade the indeterminate form of fireproof material changes a technology.

To reduce steel Bao Zhulu is operated and reduce fireproof cost of material, factory of Shibukswa of special steel company regards Japanese Great Harmony as one of special steel manufacturers, was in first 1995 VLF (vacuum steel includes stove) the indeterminate form that steel included liner to use fireproof data changes a technology. From 1997 later, this factory is in SUS (stainless steel) Al2O3 came true to pledge in wrapping packet of bottom and Bao Bi to build furnace with the steel that exceeds alloy steel production to use pouring of makings pouring construction. Changing indeterminate form recently especially the technology expands when applying at all sorts of fireproof material, because was introduced new-style and wet technology of gush filling construction, consequently establish the technology that form of fireproof material adventitious changes steel bag whole, its general situation introduces as follows.

Indeterminate form is fireproof material is pouring of construction technology introduce

As steel the bag includes form of adventitious of bottom and bag wall the construction method of fireproof material, what introduce at the outset is prevailing pouring construction method.

1, pouring construction

Pouring construction method: Above all, natural conserve of the left and right sides undertakes a long time after the construction end the bag. Then, installation frame and mixture mixer, in pouring be able to bear or endure after material, to make whole aperture fill even, vibrator of the type that use a stick undertakes aiding brace up. Again via the nature that controls a long time conserve hind undertakes drawing of patterns, the step that has firebrick to position of broken bits line next builds construction.
