Embodiment Construction

[0018] The present invention is illustrated by taking the manufacture of a saddle-shaped integral dust cover as an example:

[0019] The shape and internal skeleton structure of the saddle-shaped integral dust cover are as follows: figure 2 , image 3 shown.

[0020] 1. Skeleton production: the skeleton is composed of the outer edge main frame and the inner square lattice skeleton. Choose 50mm×25mm×2.0mm carbon steel pipe as the main frame material of the outer edge of the skeleton, 30mm×30mm×1.0mm square stainless steel pipe as the material of the inner square lattice structure in the longer direction, and 20mm×20mm×0.9mm square Stainless steel tubes are used as the lattice member material in the shorter direction. The steel pipe is cut and blanked according to the design drawing, and welded into the skeleton structure of the integral saddle-shaped dust cover.

[0021] 2. Welding of the outer stainless steel bottom plate: Cut the stainless steel sheet (δ=0.8mm) according...

Abstract

A movable dust cover arranged at lateral channel gate of blast furnace has a rectangular checked main structure consisting of a boundary frame made of carbon steel tubes or stainless steel tubes, a skeleton made of thin-wall square steel tubes, stainless steel sheet covering on said skeleton, refractory light insulating material filling in the skeleton, and refractory adhesive. Its manufacture is also disiclosed.

Description

technical field [0001] The invention relates to a movable light-weight blast furnace iron tributary ditch gate place dust cover and a manufacturing method thereof. Background technique [0002] In the process of blast furnace ironmaking, the molten iron in the blast furnace is first discharged into the main ditch of molten iron, and then flows into different branch ditch, and the molten iron is discharged into the molten iron tank transport vehicle by switching or building gates at different branch ditch . The ditch gate is usually made of amorphous refractory material, and the middle is filled with coal powder for combustion to maintain the temperature of molten iron. Larger smoke and dust will be generated when the ditch gate is opened and the molten iron flows, which will cause environmental pollution. Since the blast furnace needs frequent tapping and discharging, in order not to affect the opening and construction of the blast furnace tapping gate, there is generally ...
