- Q: How to built refractory bricks as fitting between square and circle ducts
- Use rectangle at the bottom and knife type for the top. trapezoid for junction.
- Q: how to distinguish the quality of high alumina refractory brick when you buy it ?
- see the gap between the bricks and between kiln roof and kiln wall, etc.. 6, the pressure and the volume density of Pei brick and brick Pei size, appropreate matching of high alumina powder and high aluminous aggregate and other materials, the drying and time, and the mud trapped material humidity 1. 7, to reach the requirements of production. 4, the order of loading Pei brick into kiln . should prevent the lack of a scene , the requirement , mixing time, different procedure and the order of the adding of raw materials of high alumina brick. 3, drawing plan and lack of edge of high alumina brick . 5
- Q: Lining of refractory bricks in rotary furnace
- The lining now is built with MgO-C brick, the specific time to change it mainly to see the quality and usage of MgO-C brick. A few years ago, the mills are desperately seeking furnace age, some can use thirty thousand furnace, by the way, furnace age of converter refers to the number of steelmaking furnace not time. So now most mills are not simply pursuit furnace age, but economic furnace age, currently furnace age of steel mills around us is mostly in about ten thousand to twenty thousand. In general, the furnace service of the converter is arranged with the overhaul of other equipment. This can realize the synchronous maintenance of various equipment. If the stove is too old but the maintenance is not timely, also is not to replace the lining brick timely, there will be leakage, then the furnace shell and even ring will be damaged, consequences are more serious . The reason is very simple for brick falling off. One is the poor quality of furnace brick,causing brick lining loose, rocking furnace will lead lining brick falling. the other one is the furnace lining brick is pressed too tight in the use procedure and the brick is too thin.
- Q: Whether yellow dextrin is used in refractory bricks?
- The production of refractory bricks needs yellow dextrin as bonded materials.
- Q: Where the refractory bricks rider bricks that are used for building arch and vault should be put?
- Arch and vault shall be built simultaneously from both sides of the arch of the foot to the center of symmetry, when masonry, inverting concentric reducer of arch brick is prohibited; the lock should be driven into the brick arch from the side, if the last rider brick can't be driven from the side, you can process the first 1-2 brick to make the size of the lock and the lock buckle equal, and then drive suitable rider brick from top, and use steel plate to jam-pack the side; dismantling arch tire must be performed after all rider bricks are driven and lock brick arch foot ditch masonry is completed and the final tightening nut for skeleton retractor rear.
- Q: How to prevent the refractory bricks from burning to crack?
- There is just allowed a little moisture contained in adobe.
- Q: 90 porous brick and ordinary shale brick, clay brick difference
- Porous brick is the original clay brick (now don't let in) and shale increased by a certain gap, but it is also the porosity, thickness is 90, not 53 of the original, there are also some differences in the use of solid brick and. Not for underground use.
- Q: does 90m high reinforced concrete chimney need firebrick?
- The chimney need firebricks or casting fire or acid resisitant concrete after casting, one aim is to resist high temperature, then is to resist acid corrosion. there is a variety of models of the refractory brick , you can refer to the installation quota.
- Q: Can refractory bricks be used to pave roads or build a wall?
- Refractory bricks are used to build a house, no problem
- Q: What is the raw material for the production of refractory bricks?
- Refractory raw material: Hard refractory clinker, magnesia calcia, magnesia, alumina, light burning, light aggregate etc.
