Embodiment Construction

[0022] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] Such as figure 1 with figure 2 As shown, the embodiment of the present invention provides a reinforcing rib for producing continuous basalt fiber high-life drawing bushings, the reinforcing rib 5 is arched, and the reinforcing rib 5 includes a rib column 502 and an upwardly protruding arc rib On the surface 501, the rib column 502 is welded on the lower surface of the rib surface 501; an arch hole is formed between two adjacent rib columns 502.

[0024] The reinforcing rib of the above structure can improve the service life of the wire drawing bushing for producing continuous basalt fiber. When in use, the reinforcing rib 5 is located in the cavity of the drawing bushing, and the reinforcing rib 5 is fixedly connected to the side wall plate 2 and the base plate 1 of the drawing bushing. As the basalt melt is a black melt, the heat...

Abstract

The invention discloses a reinforcing rib for a long-service-life wire-drawing bushing for producing continuous basalt fibers. The reinforcing rib is shaped like an arch and comprises rib columns and an arc-shaped rib face of which the top protrudes upwards, and the rib columns are welded to the lower surface of the rib face; an arch hole is formed between every two adjacent rib columns. The invention further discloses the long-service-life wire-drawing bushing for producing the continuous basalt fibers. The bushing comprises a substrate, a side wall plate, a plug plate, electrode plates, reinforcing ribs and discharge spouts. Each reinforcing rib is shaped like an arch and comprises rib columns and an arc-shaped rib face of which the top protrudes upwards, and the rib columns are welded to the lower surfaces of the rib faces; an arch hole is formed between every two adjacent rib columns. By means of the reinforcing rib, the service life of the wire-drawing bushing is prolonged.

Description

technical field [0001] The invention relates to components for producing continuous basalt fiber, in particular to a reinforcing rib and bushing used for producing continuous basalt fiber with long life drawing bushing. Background technique [0002] Continuous basalt fiber is a continuous fiber drawn at high speed by a platinum-rhodium alloy wire drawing bushing after melting basalt rock at 1450°C~1550°C. Bushing is one of the most important equipments in the production of basalt fiber, which is directly related to the molding quality and production efficiency of the fiber. In particular, the bottom plate of the bushing plate is prone to high-temperature creep deformation during the basalt fiber drawing operation, which seriously affects the drawing operation. In order to improve the service life of the bushing plate, the general measure is to increase the strength of the bottom plate material, such as increasing the rhodium content in the platinum-rhodium alloy, or using n...
