Abstract

The invention discloses a basalt fiber production method and a wire drawing device thereof, which relate to the technical field of basalt fiber production and wire drawing, and aim to solve the problems of easy crystallization and blockage. The device comprises a box body, a heating mechanism and a cooling mechanism, wherein the heating mechanism is installed in the box body, the outer wall of thebottom of the box body is connected with evenly-distributed discharge spouts through flanges, a thermal induction chamber matched with the discharge spouts is fixed to the outer wall of the bottom ofthe box body through screws, and the tops of the discharge spouts are located in the thermal induction chamber; an expansion bag expanding with heat and contracting with cold is arranged in the thermal induction chamber. The production method comprises the following steps of crushing and cleaning basalt ore, adding basalt ore into a melting tank of a melting furnace, and heating to 1450-1500 DEGC to melt the basalt ore. The aim of controlling the speed of the cooling degree based on the temperature of the discharge spout is achieved, the problem that the temperature difference of materials and the cooling speed are not matched is effectively solved, and reliability is improved.

Description

technical field [0001] The invention relates to the technical field of basalt fiber production and drawing, in particular to a production method of basalt fiber and a drawing device thereof. Background technique [0002] Basalt fiber is a green and environmentally friendly fiber material that is made of basalt rock through a wire drawing device after melting. At present, the processing of basalt fiber mostly adopts the method of wire drawing bushing. Although the ordinary wire drawing device can meet certain production requirements, due to There are usually heating mechanisms inside the wire drawing device, and cooling mechanisms are often installed near the discharge end. Due to the influence of the shape and installation position of the heating mechanism inside the wire drawing device, the basalt molten material must have a temperature difference, and the cooling mechanism has an effect on each output. The cooling effect at the output end is the same, which causes the basa...
