Low-beating degree ultrafine centrifugal glass wool drawing device and drawing method

The invention relates to low-beating degree ultrafine centrifugal glass wool drawing device and drawing method. The device is composed of a primary centrifugal system and a secondary stretching system, wherein the primary centrifugal system sequentially comprises an electric heating leakage plate, a steel structure, a rotary spindle, an internal combustion engine and a centrifugal plate from top to bottom; and the secondary stretching system is arranged above the centrifugal plate, and comprises a gas air inlet, a gas channel, a refractory layer, a high-temperature airflow stretching opening, a cold air stretching opening and an airflow cutter. The ultrafine glass wool fiber is small in diameter, low in beating degree, high in flexibility and excellent sound insulation and heat insulation properties.
