Analysis of low cement castables for cement kilns has a strong shock resistance

Not the same product, will bring a different effect, low cement castable cement kiln to bring what effect. Low cement castables mainly bauxite as raw material, high-performance calcium aluminate cement dosage is only 2 to 6%. The main production of ingredients than: brown steel jade 15-24, silicon carbide 6-15, coke 20, white mud 12-16, tar 18-20. Calcium oxide content is low, can reduce the formation of eutectic phase, improve the refractoriness, high temperature strength and slag resistance, for the cement kiln plays a very important role.

The raw materials were dried for 24 hours and then dried at 110 ℃ for 24 hours, respectively, and heat treated at 300 ℃, 500 ℃, 700 ℃, 900 ℃, 1100 ℃, 1300 ℃ and 1500 ℃ for 3h. (PM), linear change rate (PLC), room temperature flexural strength (MOR), room temperature compressive strength (CCS), room temperature wear resistance and thermal expansion coefficient and heat resistance of the samples were measured. Seismic performance. The results show that with the increase of heat treatment temperature, the volume density of low cement refractory castable in cement kiln decreases first and then increases again. The change rate of line decreases first and then decreases The strength of the room temperature and the compressive strength at room temperature increased first and then increased. Cement kiln with low cement castable after 1500 ℃ heat treatment after the wear less than 1300 ℃ heat treatment after the wear and tear.

So that the use of low cement castables in cement kilns has a strong shock resistance. Cement kiln construction qualified rate increased by 2%, punctuality rate also increased by about 6%, it is important that the cement kiln safety factor and service life has been improved greatly, and fully reduce the cost of secondary construction of cement kiln.

insulating castable,Clay, High Alumina insulating bricks is heat insulation material used for steel plants Heating Furnace

The use of the bricks can reduce the heat capacity of kiln walls and promote the heat efficiency of kilns. The product is applicable for constructing industrial kilns and inner lining of kilns.

 Clay, High Alumina Insulating Bricks Introduction:

Produced with unique advanced technology, the clay and high alumina heat insulating bricks possess the characteristics of high intensity for pressure and good thermal shock stability. The use of the bricks can reduce the heat capacity of kiln walls and promote the heat efficiency of kilns. The product is applicable for constructing industrial kilns and inner lining of kilns.
