Brake disc continuous siliconizing furnace and working method thereof

Abstract

The invention relates to a brake disc continuous siliconizing furnace and a working method thereof, which belong to the technical field of carbon-ceramic brake disc production. The brake disc continuous siliconizing furnace comprises an outer furnace shell, a vacuum chamber, a high-temperature reaction chamber and a low-temperature buffer chamber which are each provided with a protective gas inflation device, wherein vacuum sealing doors are arranged on the two sides of the vacuum chamber; heating pipes are arranged all around the high-temperature reaction chamber and connected with an intelligent temperature controller by means of a pressure regulator; the low-temperature buffer chamber is provided with a heat preservation layer, and the high-temperature reaction chamber communicates withthe low-temperature buffer chamber; a track and a crucible sleeve are arranged at the bottom part of the outer furnace shell, and the crucible sleeve sequentially enters the vacuum chamber, the high-temperature reaction chamber and the low-temperature buffer chamber through the track; the carbon-ceramic brake disc is pushed into the vacuum chamber after being arranged in the crucible sleeve; oxygen in a product is pumped away, an argon gas is introduced to micro-positive pressure, then the product is fed into the high-temperature reaction chamber for dissolved silicon permeation, the productis fed into the low-temperature buffer chamber from the high-temperature reaction chamber for pre-cooling after permeation, and then the product is pushed out of the low-temperature chamber for discharging, thereby achieving the purpose of assembly line siliconizing production, and reducing the production cost of the carbon-ceramic brake disc.

Description

technical field [0001] The invention relates to a brake disc continuous siliconizing furnace and a working method thereof, belonging to the technical field of carbon ceramic brake disc production. Background technique [0002] At present, domestic carbon-carbon / carbon-ceramic automobile brake discs are mostly produced by induction vacuum siliconizing furnaces, with a temperature of 1850°C to 1450°C. Due to the siliconizing process, only furnace batch production can be carried out, and continuous pipeline siliconizing cannot be realized. , resulting in cost waste, and the mass production cost is high and the cycle is long, resulting in multiple heating and cooling of the deposition furnace, high production cost, and a long production cycle limit the development speed of carbon ceramic brake discs. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a continuous siliconizing furnace for brake discs, which has the pur...
