Embodiment Construction

[0067] The processing method of ceramic roller is characterized in that: its processing steps are as follows:

[0068] 1. The ceramic roller sleeve is made of high-purity fused silica; it has high volume density, high strength, small thermal expansion, good thermal shock stability, high dimensional accuracy, no deformation at high temperature, long service life, and no pollution to glass;

[0069] 2. Blank casting of hollow roller sleeve and fixed ring;

[0070] 1).Using horizontal centrifugal casting method;

[0071] 2) Design the mold according to the design drawings;

[0072] a. Mold inner diameter = casting blank + shrinkage rate (1.025%) + coating thickness (0.8mm-1.5mm);

[0073] The casting blank refers to the size of the design drawings plus the machining allowance; the coating thickness is uniformly sprayed on the inner wall of the mold with silicon micropowder or zircon powder, and the coating thickness is 10.8-1.5mm, so that the high temperature molten steel Du...

Abstract

The invention discloses a machining method for a ceramic roller. The method comprises the following steps of manufacturing a ceramic roller shell from a raw material high-purity fused quartz; horizontally centrifugally casting a hollow roller shell and a fixing ring from a material 1Cr18Ni9Ti; machining the cast hollow roller shell and the cast fixing ring; machining shaft heads; and welding the hollow roller shell and the two shaft heads, and performing finish machining, assembly and inspection on each part. A product produced by the method is high in machining accuracy and abrasion resistance, non-deformable at high temperature and long in service life, and the production cost is lowered.

Description

technical field [0001] The present invention relates to the field of glass machinery and equipment processing, in particular to the processing of ceramic rollers [0002] method. Background technique [0003] The ceramic roller is a combined component composed of porcelain body, bearing, shaft and plastic labyrinth seal ring. The ceramic roller is a key component in the glass horizontal tempering furnace, mainly used for carrying and transporting glass in the glass horizontal tempering furnace. The existing ceramic rollers have poor thermal shock stability, are easily deformed at high temperature, have low machining accuracy, large radial runout, short service life, and scratch the glass. Contents of the invention [0004] The purpose of this invention will provide a kind of processing method of ceramic roller exactly, and it can overcome [0005] The above defectives that existing products exist. The object of the present invention is achieved in that the processi...
