Push plate with holes and for electronic material roasting

Abstract

A push plate with holes and for electronic material roasting belongs to the technical field of kiln furniture and comprises a rectangular body. A plurality of through holes are arranged on the central area of the rectangular body, and the area of the through holes occupies 10% to 20% of the whole area of the push plate. Kiln atmosphere is ensured to be smooth by changing arrangement of the through holes of the push plate, products are evenly heated, good in roasting quality, capable of ensuring strength of the push plate not to be affected by the through holes, thermal shock resistance of the push plate is facilitated, and service life of the push plate is prolonged.

Description

technical field [0001] The invention belongs to the technical field of kiln furniture, in particular to a push plate with holes for electronic material roasting. Background technique [0002] The domestic kilns for producing electronic materials are mainly high-temperature push plate kilns, and firing has high technical requirements on the thermal shock resistance of the push plate. A long time will affect the firing quality of the product; Chinese patent application 2004200232388 discloses "kiln furniture that resists rapid cooling and rapid heating". A central hole is arranged in the middle of the shed plate, and a lining plate is arranged above the central hole, and several stainless steel lines are buried along the central hole. For silk rings, the area of ​​the central hole accounts for 25-40% of the entire kiln furniture area. The push plate hole of this structure occupies a relatively large volume. Although it is conducive to uniform heat conduction, it affects the s...

[0002] The domestic kilns for producing electronic materials are mainly high-temperature push plate kilns, and firing has high technical requirements on the thermal shock resistance of the push plate. A long time will affect the firing quality of the product; Chinese patent application 2004200232388 discloses "kiln furniture that resists rapid cooling and rapid heating", and a central hole is arranged in the middle of the shed plate, and a lining plate is arranged above the central hole, and several stainless steel lines are buried along the central hole. Silk ring, the area of ​​the center hole accounts for 25-40% of the entire kiln furniture area

The push plate hole of this structure occupies a relatively large volume. Although it is conducive to uniform heat conduction, it affects the strength of the push plate and reduces the number of times of use of the push plate. In addition, several stainless steel wire rings buried along the center hole are not applicable. In a high temperature firing environment
