Problems solved by technology

In addition, because the hearth will generate impact loads during the perennial vibration load and furnace charge erosion, it is very easy to cause severe wear and tear of the hearth and bricks will fall off. The quality of the hearth bricks in the entire roasting furnace lining bricks is particularly serious

Abstract

The invention discloses a pre-laying method for hearth bricks of a multi-layer roasting furnace. The method comprises: selecting and classifying the bricks according to the main dimension tolerance of the bricks with a grade of 1mm, and checking the shape of the bricks, Exclude unqualified bricks; grind the ash surface of the selected bricks to ensure that the bricks can be tightly bonded during masonry; draw a cross center line on the pre-installed platform to make the cone of the hearth brick Facing upwards, starting from the first layer of arches, each layer of arches is lined up one by one from the outer ring to the inner ring. After the completion of the masonry, check the surface evenness, and polish the bricks whose error exceeds the predetermined value; After the arch masonry is polished, draw a cross center line on the surface of the arch, and number the bricks block by block; store the numbered bricks according to the number, wherein, in the process of masonry, the main size of the same ring is the same Grade brick masonry, and when two grades of bricks are required to be used together, large grade bricks are ground into small grade bricks for masonry.

Description

technical field [0001] The invention relates to a pre-laying method for hearth bricks of a multi-layer roasting furnace, more specifically, the present invention relates to a pre-laying method for hearth bricks of a multi-layer roasting furnace which can improve the quality of the pre-laying. Background technique [0002] Self-suspended multi-layer roasting furnace is roasting V 2 o 3 and V 2 o 5 As an important thermal equipment for raw materials, there are usually multi-layer hearths in the furnace. The upper surface of a typical hearth is a horizontal plane, and the lower surface is a conical surface, and the taper is generally small. There is a rotatable shaft in the center of the hearth, and a rake arm is installed on the hollow shaft of each hearth for raking. When the rake arm rotates with the hollow shaft, the charge is raked from the upper hearth layer by layer. [0003] During the use of multi-layer roasting furnace, due to the complex chemical composition of...
