Refractory mortar of construction relates good or bad quality of construction

1.The furnace wall is usually divided into internal wall, wall and exterior wall.Inside the wall, the wall is directly affected by the fire, and the fire brick is used.The refractory brick is divided into general type and two kinds of shaped refractory clay, from raw material (raw cement, clinker (resistant) resistant mortar prepared cooked).The outer wall is not directly under the flame of baking, the use of high-quality red (green) brick and cement mortar masonry.
2.The materials used for the inspection of furnace brick, fire clay, cement and river sand should be strictly inspected.Each brick should be edges and corners integrity, length, width, thickness of the same size, no distortion, cracks and other defects.Refractory cement, cement should carefully check the date of the factory and whether there is deterioration failure; river sand should be clean without debris.
3.The furnace wall is divided into masonry wall and arch1)Masonry furnace wall.The ratio of interior wall for masonry mortar:When the high temperature refractory brick masonry, seam width is less than 2mm within the wall, with cooked refractory mud 75%, cement 25% preparation resistance to students;When the low temperature refractory brick masonry, brick seam width is less than 3mm within the wall, with cooked refractory mud 65%, students 35%.Preparation of resistant mortar.Schamotte fineness to meet construction requirements, should use less than sieve seam width before using ash sieve.Masonry red (green) brick wall, the use of cement, lime mixed mortar, the ratio of cement: Lime: river sand =1:1: (4 ~ 6) (volume ratio).In the building process, to keep within the wall and around the schedule basically consistent, each layer of brick mortar to stagger, masonry brick staggered along the length of 1/2,horizontal staggered brick masonry long 1/4.Within the wall shall not have vertical seams. Every masonry 5 ~ 7 layer, should set the appropriate number of bricks (connected with bricks) furnace wall to a certain height,Verticality per meter less than or equal to 3mm, full height of not more than 15mm; roughness less than 5mm of brick mortar shouldbe uniform, full.(2). The roof and masonry arch furnace wall door hole upper are usually arched. Arch with wedgerefractory brick masonry, brick arch is odd, a brick vault called central lock brick, is located in the vertical line through the center of the arch.Masonry arch, masonry brick joints from both sides to the middle, less than 2mm, the last piece of the central lock brick wedge gap should be slightly less than the thickness of the brick, to insert about 2/3 longbrick is appropriate; and then use the remaining 1/3 gently into the mallet. Both sides of the brick arch (skewbacks), with special refractories brick. The upper part of the furnace wall, brick can be processed along the curved vertical masonry.Masonry arch, masonry brick joints from both sides to the middle, less than 2mm, the last piece of the central lock brick wedge gap should be slightly smaller than the thickness of brick, with about 2/3 can be inserted into the brick should be long;Baking oven is designed to be a furnace wall in the water slowly drying, to prevent the boiler when put into operation, due to the high flame temperature in the furnace, the furnace wall in the rapid evaporation of water and cracks.Oven before the boiler to the hydrostatic test, thermal insulation masonry work all over; lead the air supply system, water supply system, drainage system, coal and slag removal system in stand-alone operation, normal operation under rated load; thermal instrumentation instrumentation inspection; lighting and fire protection facilities, reliable.
