Problems solved by technology

In these patents, the green body of the heating element is made of a quasi-three-dimensional needle-punched felt body or a two-dimensional carbon fiber fabric laminated on a fixed tire mold. The green body has low density, unstable size and shape, and the green body needs to pass through Multiple cycles of "chemical vapor deposition - high temperature treatment - machining peeling - chemical vapor deposition" can achieve the required density and performance, resulting in a long production process cycle of the heating element, high production costs, and unstable performance

Abstract

The invention relates to a mould device for producing a U-shaped heating body blank. The mould device comprises a mould body, one or two movable arc moulds, a hydraulic device and a cover plate, wherein support lugs are welded on the two sides of the mould body; each end face of the mould body is provided with two guide positioning pins and two locking holes I; limit strips are arranged on the two sides of upper and lower surfaces of the mould body; each movable arc mould is a hollow semi-cylinder; channel steel is welded on the inner side of each movable arc mould and provided with two locking holes II, two guide positioning holes and two jacking screws; and the cover plate consists of an upper movable cover plate and a lower movable cover plate. The mould device for producing the U-shaped heating body blank has a simple structure, is convenient to operate, is low in cost for producing the blank, and is high in production efficiency.

Description

technical field [0001] The invention relates to a tire mold device for producing a green body, in particular to a tire mold device for producing a carbon-carbon composite material U-shaped heating body green body of a polycrystalline silicon hydrogenation furnace. Background technique [0002] The hydrogenation furnace is an important equipment for tail gas treatment and recycling in the polysilicon production process, and the heating element is the core component of the hydrogenation furnace. The traditional hydrogenation furnace heating element is generally made of high-purity graphite, and a U-shaped heating element is formed by splicing multiple sections of high-purity graphite. Any looseness and gap at the graphite connection will cause arcing and affect the normal and stable use of the heating element. Moreover, the graphite material is brittle and has low strength. It is easy to break and damage during the processing, installation, maintenance and use of the U-shaped...
