Pambuka unsur panas kanggo tungku sintering vakum

Cara transfer panas saka unsur panas saka tungku sintering vakum kanggo workpiece beda saka tungku panas listrik biasa, kang utamané adhedhasar transfer panas radiation. Unsur pemanasan utamane kalebu kromium nikel, molybdenum suhu dhuwur, grafit lan sabuk grafit (piring), sabuk tungsten lan bolong tungsten:

(1) Ni-Cr utamané digunakake ing furnaces kang suhu ngisor 1000 ℃;

(2) Molybdenum suhu dhuwur bisa ditrapake ing awak pawon ing ngisor 1600 ℃;

(3) Grafit lan tape grafit (piring) bisa digunakake ing awak pawon ngisor 2300 ℃;

(4) Tungsten sabuk lan tungsten bolong bisa digunakake ing awak pawon ngisor 2400 ℃.

The selection of the heating element is mainly determined by the sintering temperature, the physical and chemical characteristics of the product.
