Description

Technical Field

[0001] The utility model relates to the technical field of ironmaking blast furnace groove repairing equipment, in particular to a blast furnace groove repairing mould. Background Art

[0002] The main iron ditch, ridge ditch, slag ditch and other iron ditch of the blast furnace are all cast with high temperature resistant castables. During the production process, due to the continuous mechanical scouring and chemical erosion of slag iron, the blast furnace iron ditch needs to be re-cast every once in a while. The blast furnace iron ditch is wide at the top and narrow at the bottom. In order to form this structure, the blast furnace iron ditch mold is a four-sided cone shape with wide at the top and narrow at the bottom. When repairing the ditch, after the old materials in the blast furnace iron ditch are cleaned up, the blast furnace iron ditch mold is installed in the blast furnace iron ditch. There is a gap between the blast furnace iron ditch mold and the two sides of the blast furnace iron ditch. The stirred semi-liquid castable is injected from the space between the blast furnace iron ditch mold and the two sides of the blast furnace iron ditch, and the refractory material is formed. After the refractory material is formed, the blast furnace iron ditch mold can be demoulded and taken out from the blast furnace iron ditch.

[0003] In order to successfully demould, the existing practice is to add water from the water inlet of the blast furnace iron ditch mold to cool it, so that the blast furnace iron ditch mold and the refractory lining are quickly separated, and then waste oil is injected from the gap between the outer side of the blast furnace iron ditch mold and the refractory lining to facilitate demoulding. Under the structure of the above-mentioned existing blast furnace iron ditch mold, the blast furnace iron ditch mold and the refractory lining are directly adhered together. Although water cooling and waste oil can be used for demoulding during demoulding, when the blast furnace iron ditch mold is lifted by a crane, it is still easy to bring out the poured refractory material, or cause cracks in the poured main ditch, thereby affecting the pouring quality and service life of the blast furnace iron ditch. Utility Model Content

[0004] The utility model aims to provide a blast furnace groove repairing mould.

[0005] The technical solution to achieve the purpose of the utility model is: a blast furnace groove repair mold, used for pouring refractory materials of blast furnace iron water groove, the blast furnace iron water groove has two groove walls on the surface of which refractory materials are to be formed, the blast furnace groove repair mold includes a mold body, the cross-sectional shape of the mold body is the same as the cross-sectional shape of the blast furnace iron water groove, the mold body has a bottom surface and two side surfaces, the two side surfaces correspond one to one with the two groove walls of the blast furnace iron water groove, and the bottom surface and the two side surfaces in the mold body are removably covered with iron sheets.

[0006] Furthermore, the iron sheet is tied to the outside of the mold body by several iron wires. The iron wires are not only convenient for tying, but also can be cut off when demoulding after the refractory material is formed, so that the mold body and the iron sheet can be quickly separated, and the operation is more convenient and efficient.

[0007] Furthermore, a plurality of the iron wires are arranged and distributed at intervals along the length direction of the mold body. This arrangement makes the binding operation between the iron sheet and the mold body more secure.

[0008] Furthermore, the mold body is in the shape of a quadrangular pyramid.

[0009] The utility model blast furnace groove repairing mold has the iron sheet detachably covering the bottom surface and the two side surfaces of the mold body, so that the iron sheet between the cast refractory material and the mold body plays an isolating role during the casting process. The isolation of the iron sheet prevents the mold body from contacting the cast refractory material, so that during the demoulding process, the mold body can be easily lifted out of the blast furnace iron groove by simply disassembling the mold body and the iron sheet, and quickly demoulding.

[0010] In the utility model blast furnace ditch repairing mold, after the iron sheet wraps the bottom surface and the two side surfaces of the mold body, the mold body does not directly contact the cast refractory material. When demoulding, strictly speaking, it is only necessary to separate the mold body from the iron sheet. Since there is no adhesion of castable material between the iron sheet and the mold body, and the integrity and structural strength of the iron sheet are high, it is easy to separate the mold body from the iron sheet, and the separation can be completed quickly, and the demoulding efficiency is high. In addition, the iron sheet located between the cast refractory material and the mold body can protect the refractory material, avoiding the mold body from causing secondary damage to the cast refractory material. The casting quality of the refractory material is high, and the service life of the blast furnace iron ditch is extended. BRIEF DESCRIPTION OF THE DRAWINGS
