Q:What is the raw material for the production of refractory bricks?
Refractory raw material, sodium silicate as a binder, and lightweight aggregate, magnesium sand, magnesia calcium. Magnesium Oxide, bauxite, and then lightly burn: Hard refractory clinker
Q:What is the life of an old fashioned refractory brick kiln transformed into a flat topped tunnel kiln? what material should be used to transform the old fashioned refractory bricks vault kiln to flat tunnel kiln, and how long is the service life?
123
Q:What is the advantage of the ceramic fiber material compared with the refractory brick?
Ceramic fiber material is heavier than refractory bricks, property of machinery operation, low heat capacity, and has high anti-stretchability and good thermal shock resistance, low thermal conductivity make its thermal insulation effect is ten times than refractory brick, it won't has crack in sudden coolness and heat, and the construction is much easier than that of refractory brick, not delaying the production.
Q:how much fireclay is needed for 10000 refractory bricks?
The amount of mud used for T-3 refractory brick is 0.3KG. if the tiler is skillful, the furnace should have joint of 2mm.
Q:What are the specifications of clay brick and cement brick construction?
Chinese in the spring and Autumn period has created a square and brick, Qin and Han Dynasties brick technology and production scale, quality and variety have significant development, known as "Qin Zhuanhan tile".
Q:How to wipe off the white paint on the refractory brick (red).
Cover the wall gap with tape. . Then paint the bricks. Finally, tear the tape off. .
Q:How to count the number of loading refractory bricks?
Use one meter by one meter wooden raft-towing: use one meter raft-towing to count: Known your brick is T-3 standard bricks, each four layers lies down 15 and sidewards is 4 =64; according to 3.4kg, 47 clay bricks can hold 10 to 12 layers. According to the upper limit, each raft-towing can hold 2.3 tons
Q:Can refractory be used to sharpen knife?
Many factories build a smelting furnace by using this kind of bricks. A special knife grinder can be used to sharpen knife, can on 1. They are sizing and non-sizing refractory bricks respectively. Refractory brick is now a lot of fields and industry will introduce one of the raw materials. Products are divided into two different types, refractory brick as a high temperature resistance of the raw materials. In simple terms, working temperature is 770 DEG C, 580 C and 1, of course, refractory bricks also can be used to sharpen knife, use smooth brick to sharpen, need to choose high hardness
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 is the ratio of refractory mortar and refractory bricks, such as how much refractory mortar is needed for a ton of refractory bricks?
Go to the refractory factory to buy some refractory clay that is of the same material as refractory bricks, generally boiler uses clay refractory mortar.
