Glass wool production line (tank furnace)

1. Brief introduction

Glass wool is a kind of insulation materials which is made of natural ores, such as quartzite, dolomite, feldspar, limestone and so on. With the features of low density, fireproof, thermal insulation, the glass wool has found a wide utilization in the fields of petrochemical industry, architecture, etc.

2. Production process

The raw materials added with auxiliary agents such as calcined soda and borax are melted into glass fluid in the tank furnace. The lava is drawn, blown or thrown into very thin fibers under centrifugal force of the spinner. The forming fiber will be collected to be original blanket by wool collecting machine. The original felt is sent into the curing oven to be solidified and shaped by the conveyor. After curing, the products will go through the cooling section. It will be cut by slitting cutter and cross cutter according to the setting length. Finally, it will become the final products such as board, blanket.

3. Equipment introduction

3.1 Melting system

This production line adopts tank furnace which is made up of different refractory materials and uses natural gas as fuel.

3.2 Fiber forming system

This system uses spinner to produce glass wool fiber from vitreous fluid. It is the key equipment of the whole production line and decides the quality of the final product.

3.3 Glass wool collector

Glass wool collector could collect fibers into crude felt which is then sent to curing oven via the transition conveyor.

3.4 Curing oven

Curing oven could heat and shape glass wool layers containing binder as per the density, size required for products. It could make binder and fibers polymerize into one, producing glass wool blanket and board.

3.5 Conveying and cutting machines

The conveying machine could convey the cured glass wool products to the cutting system and cool the products at the same time.

The cutting system could proceed longitudinal and crossing cutting to make required products.

3.6 Blanket / felt-rolling machine

It could roll the glass wool blanket into rolls and facilitate the packing of product.
