Detailed Description

Referring to fig. 1, the utility model discloses a horizontal circumference kiln headwall work door inside lining masonry structure, masonry structure include horizontal circumference kiln headwall work door and build by laying bricks or stones the headwall brick body around the work door, and the headwall brick body is built by laying bricks or stones a plurality of headwall bricks 5 and is formed. The horizontal type circumferential kiln end wall working door lining comprises a first plane, a second plane, a third plane and a fourth plane, wherein the first plane is opposite to the third plane, the first plane and the third plane are built through a plurality of vertical bricks 3, and the first plane and the third plane are connected with an end wall brick body in a building mode; the second plane is built by a plurality of base bricks 2, and the fourth plane is built by a plurality of lintel bricks 4; the second plane is connected with the end wall brick body through a plurality of processing bricks 1 in a building mode, and the fourth plane is connected with the end wall brick body through a plurality of processing bricks 1 in a building mode. The base brick 2, the vertical brick 3 and the lintel brick 4 are all shaped bricks, but are not processed bricks. The shaped bricks refer to non-processed bricks, and are various special-shaped bricks (non-cuboid bricks) which are customized from refractory material manufacturers according to the building requirements of special parts and are fired by special moulds; the shaped brick does not need to be cut by a cutter, so that the shaped brick is not subjected to mechanical damage, has no cutting surface, and has better integrity, higher strength and better high-temperature resistance. And filling materials are placed between the masonry structure and the shell of the horizontal circumferential furnace, and the masonry structure is embedded in the end wall of the horizontal circumferential furnace and forms a whole with the end wall.

The utility model relates to a masonry structure for horizontal circumferential kiln end wall working door linings of a horizontal converter, a rotary refining furnace, a bottom blowing furnace and the like for non-ferrous metal smelting. The main function of the horizontal circumferential furnace end wall working door is to provide personnel and material access channels on the premise of ensuring safety and damaging the end wall in a small area when a furnace mouth is upward during the shutdown maintenance of the furnace. The masonry structure of the utility model is positioned at the center of the horizontal type circumferential kiln end wall. The method comprises the steps of pre-positioning an end wall center when an end wall is built, positioning the position of a working door according to the end wall center and the size of the working door, machining end wall bricks below base bricks of the working door according to the position of the working door when the end wall is built to the lower edge position of the working door, guaranteeing the levelness of the upper surface after finishing, building base bricks, positioning vertical bricks after the base bricks are positioned, building upper lintel bricks after the vertical bricks are positioned, building wall bricks at two sides of the working door bricks synchronously, and building upper machined bricks and end wall bricks after the end wall bricks at two sides are built to be level with the lintel bricks.
