EQUIPMENT MANUFACTURING FIBER FROM MINERAL MELT Russian patent published in 1999 - IPC

FIELD: production of heat insulation materials. SUBSTANCE: equipment incorporates guiding trough, rotary cup with grooves uniformly arranged on its internal surface and directed from center of cup to its periphery and ring blasting head. Grooves are made at angle equal to α = arccosv2o

+v2k-v2а/2•v_o•v_k, where α - is angle included between vectors of relative velocity of jet of melt in groove and backward continuation of vector of circumferential velocity of rotation of cup ( with 60 deg<60^°<α<160^°;<160 deg ), v_o is circumferential velocity of rotation of cup; v_k is relative velocity of jet of melt in groove; v_a is absolute velocity of jet of melt across groove outlet. EFFECT: improved quality and reduced diameter of fiber, increased productivity. 5 dwg
