Roasting furnace burner channel refractory ramming material construction method

Abstract

A construction method of a refractory ramming material for a burner channel of a roasting furnace is characterized by comprising the following steps: a, manufacturing a center line control device and a solid wood mold, and b, carrying out specific construction operation on the refractory ramming material for the burner channel of the roasting furnace, which comprises the following steps: 1) mounting the center line control device after construction of light castable and light refractory bricks of the burner channel is completed; 2) ramming the refractory ramming material 3 on the periphery of the first mold, then removing the buckle, removing the first mold, and galling the surface of the refractory ramming material on the inner wall of the hole; and (3) sequentially ramming the refractory ramming materials on the peripheries of the second mold to the fifth mold according to the operation in the step (2) until the refractory ramming material construction of the burner channel of the roasting furnace is completed. The construction method for the refractory ramming material of the burner channel of the roasting furnace has the advantages that the center line and the hole diameter of the burner channel are accurately controlled, the construction quality of the refractory ramming material of the burner channel is guaranteed, the control method is simple and convenient, the construction efficiency is improved, a solid wood mold can be recycled, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the construction of a refractory ramming material for a roasting furnace, in particular to a method for constructing a refractory ramming material for a burner channel of a roasting furnace. Background technique [0002] There is generally one or two spray roasters in the cold-rolled acid regeneration station. The roasting furnace is a cylindrical steel structure cylinder. The calciner is lined with acid-resistant refractory bricks. There are generally three burner passages in the roaster, which are evenly distributed along the circumferential direction. The shape of the burner channel of the roaster is complex, and it is an irregular cylindrical hole with a length of more than 2000mm. The size of the burner channel is strictly required, the allowable error of its center line is ±1mm, and the allowable error of the hole diameter is ±2mm. Due to the complex shape of the channel, the centerline and hole diameter of the hole du...

AI Technical Summary

Problems solved by technology

The size of the burner channel is strictly required, the allowable error of the center line is ±1mm, and the allowable error of the aperture is ±2mm. Due to the complex shape of the channel, the center line and aperture of the hole are not well controlled during the construction of the refractory ramming material, resulting in the refractory ramming of the burner channel. Construction quality problems, low construction efficiency, and increased construction costs

[0003] Therefore, there are above-mentioned inconveniences and problems in the known roasting furnace burner channel refractory ramming material construction mode
