- Q:Can you direct the clay brick walls embryo
- Must not。 Not damp, damp, air tight, poor pressure bearing, bad adhesion between bricks and bricks
- Q:How to make the adhesion between refractory brick and the inner wall of the boiler more firm?
- Professional furnaceman who can weld pins in the boiler steel plate is needed when have the bricklaying, mortar overflowing, connect with the refractory brick
- Q:can the refractory sand be used to make refractory bricks?
- yes, a lot of refractory sand is made by broken refractory brick, they have the same function.
- Q:What are the differences between thermal?insulation?bricks and refractory bricks?
- Thermal insulation brick is thermal insulative; refractory brick is high temperature resistant.
- Q:What is the heating temperature in the test method of thermal shock resistance of refractory bricks
- 1, quenching (air cooling or water cooling), after the completion of the specified number of times. 2, maintain 20min, introduce the following types briefly. 3, repeated testing and record the times of the material produces macro cracks. The thermal shock resistance is shown by the times of thermal cycle of damaging half of the heated end face, quenching(air cooling or water cooling ) there are many expressions and testing methods of the thermal shock resistance, and then dry. Put the heating end surface of standard size brick((200~230mm) X (100~150 m K (50~100mm) claw)into the preheated to 1100 DEG C 50mm in furnace, quenching (air or water), then quenching in room temperature water for 3min, measured the maximum temperature of sample surface produces cracks. After the temperature of the material rises to a predetermined temperature, the ratio of residual anti-bending strength and anti-bending strength at room temperature before heat shock, after the material rises to various temperatures, measure its strength retention rate.
- Q:What are the application of used refractory brick pieces?
- auxiliary material made of refractory bricks or refractory is not as good as that of bauxite.
- Q:Why is the brick instead of solid clay brick
- Shale is a sedimentary rock weathering hard substance, which is relatively hard, mainly from clay minerals and small clay particles into the pressure, cementation, weathering after the formation of hard substances, such substances are relatively hard.
- Q:Whether the cement kiln refractory bricks belong to hazardous waste or not?
- No, there is no harmful gas produced, and it will not pollute the ground.
- Q:why the color of refractory brick is white after high temperature firing when the meteorite is black after the burning?
- There are different reasons. Meteorolites can mainly be divided into three types, iron meteorites (iron nickel alloy): Stone meteorites (the main component is silicate), and stony iron meteorites(the mixture of iron and silicate)
- Q:What are the weak points of clay bricks?
- Clay bricks are clay products with Al2O3 content of 30%~40% aluminum silicate material. Clay brick is made of 50% soft clay and 50% hard clay clinker, according to the requirements of a certain particle size. After molding and drying, the clay brick is burnt at high temperature 1300~1400 degrees celsius. The mineral composition of clay brick is mainly kaolinite (Al2O3, 2SiO2, 2H2O) and 6%~7% impurities (potassium, sodium, calcium, titanium, iron oxides). The sintering process of clay brick is mainly the process of the continuous dehydration of kaolinite and the formation of crystallization of mullite (3Al2O3. 2SiO2).
