OEM Supply Casting Refractory Cement - Precast Block – Topower Detail:

Description

Precast block also known as unshaped refractory prefabricated block, is mainly made of refractory castable and refractory plastics. Its classification includes castable prefabricated block and plastic prefabricated block; there are aluminate cement, water glass, Phosphoric acid and aluminum phosphate, clay binding and low cement binder prefabricated blocks; according to the type of aggregate, it is divided into high alumina, clay, siliceous and corundum prefabricated blocks; according to the molding method, it is divided into vibration molding and vibration compression molding And ramming and forming prefabricated blocks; the mass of prefabricated blocks is dozens of kilograms to several tons, so they are divided into large, medium and small prefabricated blocks; the prefabricated blocks are equipped with steel bars and anchors, so they are divided into ordinary prefabricated blocks and steel prefabricated blocks. Blocks and anchors prefabricated blocks, etc.

Features

1. It has the advantages of high temperature resistance, corrosion resistance, abrasion resistance, high strength, and good thermal shock stability.

2. The construction is simple and easy, the construction period is short, the construction time is saved, the construction cost is saved, and the construction site is not affected by the construction environment and seasons, ensuring the construction quality

3. Low cost and low investment

4.Precast blocks are assembled with tenon joints, and there is no straight gap. Compared with refractory bricks, it can reduce masonry ash joints, ensure the overall airtightness of the furnace body, and reduce energy consumption.

Application

In industrial kilns and thermal equipment, precast blocks are used to build the furnace, which can realize mechanized hoisting, save labor and labor, shorten the construction period, and increase the furnace operation rate.

Precast blocks can be used to build thermal kilns such as blast furnaces, hot blast stoves, heating furnaces, electric furnace tops, iron ore powder roasting shaft furnaces and pellet roasting furnaces. So far, precast blocks are still widely used in tapping troughs, electric furnace tops and roasting furnaces. Use and play a greater role.
