Q:Which is best of refractory brick press machine?
Rub press machine have been forced out. Without permanent magnet. The electric screw press machine is suitable for the forming of refractory bricks. Use Kehui switch reluctance to servo motor to drive electric screw press machine, have the ability of high quality electric screw press machine, no water cooling, high efficiency and energy saving, green and environmental protection.
Q:The matching ratio of masonrying refractory bricks cement
Size of brickwork joint: Vertical and horizontal seam are 2 ~ 3 mm. The ratio of seam mud: Refractory clay mud 100%; per m3 dry, clean industrial water 400 ~ 600t/, no more than 3mm
Q:what type of refractory bricks does TZ-3 stands for ?
65mm high, 230mm long, 114mm wide is the national standard T-3 refractory brick
Q:What is the difference between clay brick, glazed tile and brick?
Clay bricks are actually a kind of clay bricks, mainly made of solid bricks! It is a product of continuous optimization of products and upgrading of traditional techniques. Usually made of high quality clay and clay brick clay high temperature firing, using natural clay as main component, quartz and feldspar as aggregate, construction bricks after sintering the formed. The nature of clay brick belongs to low temperature brick, the burning temperature is about 800 degrees Celsius, the water absorption rate is higher, and the general water absorption rate is 8%--10%.
Q:What are the main constituents in non clay brick sintering?
Sintered clay brick, it is through the mining soil, brick making, modulation, drying, roasting and cooling produced, roasting coal amount is solid sintered clay brick coal blending amount of 20-60%, the amount of coal to ensure product's surface.
Q:What is the use of refractory bricks
Refractory bricks are mostly used as furnace lining in high temperature industry. Such as the iron and steel industry blast furnace, hot blast furnace, converter; colored reverberatory furnace
Q:How much fireclay is needed per cube refractory bricks?
Normal refractory bricks need to use 70-80kg refractory mud each cubic . In fact, this can be calculated, because the volume of refractory bricks and refractory mud density can be measured. Of course, here is an important point, that is the size of the brick seam, 1mm brick seam and 3mm is significantly different. Sichuan brand refractory mud has many kinds, like high aluminum, clay, corundum, magnesia, insulation and so on, the dosage is different.
Q:Can mud and salt be used as refractory materials
Clay can be used as a refractory material, but salt can certainly not be used.
Q:cement concrete What kind of cement should be used to manufacture high temperature resistant Kang cement?
Portland slag cement 325 or 425. Use phosphate cement or aluminate cement. Use portland cement. You can also use the fragment and power of waste refractory brick or fireclay brick or aluminous refractory brick.
Q:Do refractory bricks insulate heat?
Refractory bricks have a certain ability of heat insulation, but its thermal insulation is far less than that of glass fiber and wool.
