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:Do refractory bricks need to be sent to the lab to test after arriving the site?

Other is nothing, generally it does not need, whether single weight meets the requirements, whether the appearance is regular, usually only to see whether the size is standard, it is set in the procurement

Q:What is the use of refractory bricks

Antifreeze

Q:What mud is the refractory brick made of?

The main material of the ordinary refractory brick is clay, the main component is aluminium oxide.

Q:can diatomite?brick be used as thermal insulation refractory brick?

yes, it has good thermal insulation the raw material is cheap, diatomite?brick is a kind of thermal insulation refractory brick with good performance.

Q:What is refractory brick? What is refractory clay? ?

Refractory brick is a kind of brick that is fireproof, refractory soil is the soil that is fireproof

Q:the refractory brick in glass furnace burner was burning, the bricks on both sides of the fire hole were burning the blocked it, what will cause brick burning?

The firebrick in glass melting furnace is mainly consisted of zircon brick, other ordinary refractory materials can not effectively prevent the erosion of glass solution. Because the glass melting liquid is eutectic mixture compared to the refractory bricks, it penetrates into the refractory brick and reduces its original performance, simply speaking, the glass melting liquid dissolves the refractory bricks as eutectic mixture .

Q:What kind of refractory material is used in the furnace when the boiler reaches more than 1200 degrees?

except refractory brick, refractories include refractory concrete (refractory cement+aggregate), fire-resistant insulating layer (refractory cement+vermiculite powder or refractory cement + diatomaceous earth) and so on.

Q:What is the difference between the refractory bricks, hand-made bricks and the machine pressure bricks?

Hand-made brick mainly produces brick that is not easy to produce molding Machine pressure brick adopts 100 tons of press machine to mold the density of hand-made brick is not enough, it's light; machine pressure bricks can only produce bricks that produce molding at a time, hand-made bricks mainly adopts hydraulic vibration molding machine
