커런덤 멀라이트 벽돌 1700 ℃ 푸시 플레이트 가마

커런덤 멀라이트 벽돌 1700 ℃ 푸시 플레이트 가마

1700℃ push plate kiln is a continuous heating and sintering equipment that has been improved several times on the original porous kiln. 오늘, PER Resistant Materials introduces 강옥 물라이트 벽돌 for 1700℃ push plate kiln to those who are interested in corundum mullite bricks or push plate kilns.

What Is a Pusher Kiln? Why Choose Corundum Mullite Bricks?

Push-slab kiln is a tunnel kiln, and the refractory material used for the lining is selected according to the products produced and the temperature and heat source inside the kiln.
The kiln lining of the 1700℃ pusher kiln needs refractory bricks with good thermal shock resistance according to the characteristics of the kiln, and corundum mullite bricks are recommended, which have good thermal shock resistance.
The design of the combustion chamber on both sides of the pusher kiln using coal heating and combustion is called a coal-fired pusher kiln.
With the increasing awareness of environmental protection, the use of coal-fired pusher kilns is more often changed to gas furnaces, using natural gas or gas for combustion heating.

Commonly Used Refractory Materials For Pusher Kilns

The heat loss of a pusher kiln is mainly concentrated in the heat dissipation of the kiln body. Flue gas takes away sensible heat and incomplete combustion.
The four aspects of heat loss are heat dissipation from the kiln body, incomplete combustion, and the removal of sensible heat by the flue gas of the pusher bricks and kiln furniture. 그러므로, taking corresponding measures for these aspects is the key to energy saving and consumption reduction.
요즘에는, most manufacturers use refractory bricks for kiln walls to reduce one-time investment. According to the kiln temperature, 높은 알루미나 벽돌, 점토 벽돌, 강옥 물라이트 벽돌, 등., the middle and the top of the kiln are insulated with light insulation bricks or insulation materials.

Advantages Of Corundum Mullite Bricks For Push-Slab Kiln

Corundum mullite bricks for push plate kiln at 1700℃ are made of corundum and mullite as the main raw materials, which are fired at high temperature under oxidizing atmosphere by adding the appropriate amount of alumina, silicon oxide superfine powder, 및 첨가제.
Corundum mullite products billet is formed by a 300t friction press, and the density of the billet is 2.7g/cm3. The billet is dried in a tunnel dryer. The inlet temperature is 40~50℃, the drying temperature is 130℃, the drying time is 48 시간, and the moisture of the billet is not more than 1.5%. The products are fired in the tunnel kiln with a firing temperature of 1550℃ and a holding time of 10 시간.

The physical and chemical properties of corundum mullite brick are: Al2O3 is greater than 85%, Fe2O3 0.45%, 겉보기 다공성 19%, room temperature compressive strength greater than 55MPa load softening temperature greater than 1700℃, 히팅라인교체 (1600℃, 3시간) -0.1%, 열 충격 저항 (1100℃ water cooling) 보다 큼 30 타임스.
This product can be directly contacted with flame, anti-flaking, 고온 저항, can be used as heat insulation lining of high-temperature industrial furnaces, but also as the working layer of other industrial high-temperature kilns.
It is mainly used in the petrochemical industry, large and medium-sized ammonia gasification furnaces and magnetic material gas furnace materials, 고온산업가마 지원시설자재, 등.

The corundum mullite brick for the 1700℃ push plate kiln is introduced here, hope it will be helpful to you. PER refractory company as a professional refractory manufacturer can produce more than forty different types of refractory insulation products. Product types are distinguished from the type and formula ratio, a wide range of products, and cheap. Basically can meet the current stage of a variety of large boilers, industrial furnaces, and other thermal equipment needed for high-temperature requirements, product quality is worth your trust.
