Precast Block
Precast block was precasted by high strength castables with a super high purity cement. The quality ranges from tens of kilograms to several tons, so it is divided into large, medium and small prefabricated blocks.
1.The overall structural strength is high
2.Save time, save on-site mixing, pouring or pounding, baking and other steps of refractory castable
3.Save the consumption of refractory materials such as refractory mud
4.Arbitrarily pre-made into various shapes, good thermal shock stability
5.high strength and good resistance to spalling
Precast Block Description
Precast block prefabricated blocks are equipped with reinforcing steel and anchors, so they are divided into ordinary prefabricated blocks, reinforced prefabricated blocks and anchor prefabricated blocks Wait. And in industrial kilns and thermal engineering equipment, the use of prefabricated blocks to build furnaces can achieve mechanized lifting, save people and save energy, shorten the construction period, and improve the furnace operation rate.
The Application of Precast Block
Precast block produced for extreme applications such as roof, spout and taphole block for EAF, bubbling sleeve and well block for ladle and dam block for tundish.
Precast block in industrial kilns and thermal engineering equipment, the use of prefabricated blocks to build furnaces can achieve mechanized lifting, save people.
Precast block used in thermal kilns such as blast furnaces, hot blast furnaces, heating furnaces, electric furnace roofs, iron ore roasting shaft furnaces and pellet roasting.
