Product Description:

Metal bonded unburned sliding gate

     This kind of sliding gate importing special metallic additives, which generate the phase has excellent high temperature performance behavior in the process of using. The using effect on the large and medium-sized steel ladle and the tundish is good.
     Metal bonded unburned sliding gate has the following characteristics:
Sliding gate do not have carbon, there will be no carbon oxidation cause massive sgraffito surface, which is more suitable for low-carbon steel, ultra-low carbon steel and the casting of Stainless steel. Magnesia bonded sliding gate is particularly well suited for high calcium treatment steel, killed steel, rimming steel, etc. For special steel there will be no groove at the sliding zone.
Good thermal shock stability and cracks in using is small, guarantee the security of casting steel.
The use of the product performance is stable and the production cycle is short.

Q:Is there any special requirements for the building blocks of the smoke and gas wells, how about the refractory bricks?
There are no special requirements. Not necessarily need refractory bricks, red bricks are ok. The building size of the flue is according to the smoke exhaust rate.
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:What raw materials are used for making refractory bricks
That is silicon aluminum refractory brick/, it can be divided into five types:thermal insulation refractory brick, alkaline series refractory brick, refractory brick containing zirconium, carbonaceous refractory brick/. Refractory bricks are divided according to the ingredient of refractory. Refractory bricks are generally made from refractory clay (kaolin) or other refractory materials.
Q:What is the best color of refractory brick
Clay refractory brick: Yellow and deep yellow; acid-proof brick: Red, high alumina brick Beige, a little white; square viewing brick: Yellow, red, white, gray, brown, brown, nigger-brown and so on; color is just one aspect of the selection of refractory bricks, it mainly is to see the inherent quality
Q:application of phosphate refractory bricks
The 4 properties of phosphate refractory bricks: (1) high strength wear resistance (2) and chemical erosion (its alkali resistant ability is better than that of clay brick and high alumina brick) (3) and good thermal shock resistance (4) high load softening temperature in rotary kiln, kilneye, kiln Zone door cover, cooling machine and lining refractory brick falling parts easy to loose
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:What is the role of refractory brick, whether is there any books to introduce refractory bricks
Fire resistant, flame retardant, used for building stove and firewall,
Q:How many degrees of refractory brick if its surface turns red, how to test the temperature of refractory brick after it is burnt to red.
But it depends on materials; for example, if clay brick is pink, it calls underburnt temperature is 700 degrees -900 degrees, paste red is called overdo temperature 1350 degrees -1390 degree, if the color turns heavier, it will be deformation. there are many reasons for refractory bricks sintering
Q:Do cement kiln refractory bricks have quality guarantee period? can them still be used for a long time's pile?
They of course can be used. The plant will produce some bricks for standby application in advance, so they put for a period of time is completely no problem
Q:What material does tile tunnel kiln use to replace the refractory brick to have better insulation effect and save the maintenance and prolong the service life?
Yes, but the cost is high, refractory material should be the most affordable at present.
