What is the difference masonry way between different parts of refractory bricks?
Refractory brick masonry should be staggered brick joints, brick need to use refractory mud (dry puzzle with dry refractory powder) to fill, masonry process until put into production, to prevent masonry damp. In order to compensate for the volume expansion of the masonry after heating, the masonry needs to be designed according to the design and specification requirements.
Refractory brick masonry wall, bottom, roof, pipe lining, brick lattice, combined brick masonry and expansion joints set aside. Masonry wall in accordance with its form is divided into two types of straight wall and curved wall. Straight wall before the masonry, the furnace floor should be the lowest level of the base surface leveling, on the basis of the furnace or steel structure according to the construction line. Measuring the vertical and horizontal center line and other reference line, in ensuring the size of the various parts of the furnace under the principle of accurately find the wall size line.
Wall masonry to flat vertical, each layer of Refractory brick to pull the masonry. The wall level of the wall is checked by foot and level, and the vertical or inclination of the wall is modeled, the wire hammer and the ruler are checked. In the same layer, the brick should be staggered according to the rules, the mud inside the brick to be full, the surface should be tightly tackled. After the corner of the masonry heated, the expansion of stress is concentrated, is the weak link of the wall, should be carefully processed and assembled refractory bricks, to get the wrong seam and tight seam, masonry wall stack up and down the adjacent layer of vertical joints should be staggered. Straight wall if the width of less than 450mm holes, brick when the brick layer by layer, each layer of the protruding part of the brick shall not exceed 75mm; if the width of the hole below 250mm, can be processed according to drawings required masonry The The top of the wall to maintain the level, if necessary, available processing brick leveling.
Arc-shaped wall masonry: arc-shaped wall, including round wall and curved wall two, widely used in blast furnace, hot air furnace, iron furnace, mixing furnace, conversion furnace and rotary kiln. The horizontal vertical joints of the arc-shaped wall are called radiating joints, and the longitudinal horizontal joints are called girders. The curved wall is made of wedge-shaped brick or profiled brick, and the masonry should be carefully machined in the contact between the steel structure and the anti-arch surface. Masonry tiles to be built in the inner shell. When the wall is set up in the center of the stove, the masonry is full.
When the masonry roof with curved roof, ring top, hanging top, the shell center of the vertical error to meet the requirements of the arc-shaped wall masonry can be the top of the furnace as the base surface. When the shell is sprayed on the shell and the size is accurate, the arc-shaped roof (vault) masonry, according to the arch shaft masonry, spray coating can also be the base. The arc of the curved wall is based on the parabolic arch and the catenary arch. Industrial furnace arc furnace top for the arc shape, the masonry and straight wall of the same requirements.
