Why can

At present domestic galvanized industry, whether it is normal flame galvanizing furnace, or high-speed pulse galvanization furnace, in addition to the annuo launched hot galvanizing furnace type, so far, the use of heavy and light refractory brick masonry materials.

The comparison between "lightweight heat insulation, pressure resistant, non-sintered low temperature pouring material" and "heat resistant brick masonry insulation layer" has obvious application advantages:

"Heat resistant brick insulation layer" by general heat-resistant brick masonry, galvanizing furnace to be heated, he quickly absorb heat stove heating went slowly, and in the furnace need cool, because it's heat resistant so heat evaporate slowly formed a heat preservation environment cause temperature drop too slowly.

General refractory brick masonry insulation layer, because the brick aperture, the enterprise staff cannot do when building of accuracy of thermal furnace masonry, caused a large number of aperture, increased the heat transmission of the penetrating to outside.

As the galvanizing furnace is placed above the thermal insulation layer, if is heat-resistant brick, galvanizing furnace in the process of heat expansion, will let the furnace bottom and insulation brick produce huge friction, the heat resistant brick masonry has some gap widens, and galvanized furnace in the process of cooling, the friction of the furnace bottom and heat-resistant brick, far less than the friction between the pressure of refractory brick, so will cause the masonry crack thoroughly split, cannot place, therefore, often in the production process for hot dip galvanized heating, a ceasefire, can accelerate the heat insulation layer to the furnace bottom through sexual transmission, resulting in huge loss of heat, greatly reduces the galvanizing furnace thermal efficiency.

Compared with the refractory brick unburned brick note material, simple process, energy saving, low cost, is advantageous for the mechanized construction etc., used in zinc furnace base for the needs of the pressure and heat insulation performance is better than that of refractory brick, and can reduce the galvanized based heat furnace, improving the production efficiency.
