Embodiment Construction

[0014] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0015] Such as figure 1 The trimming tool for the iron mouth mud sleeve shown includes a drill rod 1 provided with a drill head 1-1 and a drill tail 1-2. The middle section of the drill rod 1 is provided with a striking baffle 2. A striking slide hammer 3 is installed between the tails 1-2; the striking slide hammer 3 is set on the drill rod 1, and the tail baffle 4 is provided on the drill tail 1-2, which can prevent the striking slide hammer 3 from the drill tail 1-2. 2 slipping off, the tail baffle 4 is connected with the drill tail 1-2 through a screw, which can facilitate the disassembly and assembly of striking slide hammers 3 with different sizes and weights to obtain different striking strengths; between the striking baffle 2 and the drill bit 1-1 A triangular rib plate 2-1 is provided, and the triangular rib plate 2-1 is fixed on the drill rod 1 and the hitt...

Abstract

The invention discloses an iron notch mud sleeve finishing tool, and relates to the technical field of the blast furnace smelting tool manufacture. The iron notch mud sleeve finishing tool comprises adrill rod provided with a drill bit and a drill shank. A middle position of the drill rod is provided with a beating baffle. A beating sliding weight is throughout installed between the beating baffle and the drill shank. The beating sliding weight is sheathed on the drill rod. The drill shank is provided with a tail baffle. The tail baffle is connected with the drill shank through a screw rod. Atriangular rib plate is installed between the beating baffle and the drill bit. The triangular rib plate is fixed on the drill rod and the beating baffle. The drill bit is welded on a bolt, and connected with the drill rod through the bolt. Problems that a current iron notch mud sleeve needs to be operated by multiple persons and a finishing speed of the iron notch mud sleeve is slow are solved.

Description

technical field [0001] The invention relates to the technical field of manufacturing tools for blast furnace smelting, in particular to a repairing tool for a blast furnace taphole sheath. Background technique [0002] The taphole is located at the lower edge of the hearth, and it is the only channel for discharging slag and iron in the blast furnace smelting production. The working environment of the iron gate is harsh, and it has been eroded and scoured by high-temperature slag and iron for a long time. After the blast furnace is enlarged, high wind temperature, oxygen-enriched injection, and high-pressure operation have increased productivity, and it is necessary to strengthen the maintenance of the iron gate. The integrity of the iron hole mud sleeve can effectively reduce the phenomenon of mud leakage or wind blocking, and reduce the consumption of refractory materials and spare parts in front of the furnace. [0003] The molten iron is sprayed out from the tap hole, a...
