1 Scope

GB/T 10067.46-2014 is the Chinese national standard on basic specifications for electroheat installations-part 46: resistance bell furnace, in the field of manufacturing engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 3 September 2014 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 February 2015. Classification: ICS 25.180.10, CCS K61. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This section GB/T 10067 specifies the various types of cover resistance furnace (hereinafter referred to as "hood-type furnace") general technical requirements, test side Method, inspection rules, marking, packaging, transportation, storage, and ordering and delivery. This section applies to 4.1,

5.2 according to the design requirements, mainly for normalizing steel and cast iron and other materials in the natural atmosphere Annealing and annealing process, as well as steel or copper-based alloy in a protective atmosphere coils, wire coils and other materials of a cover-type resistance furnace. This section also applies to a similar cover-type resistance furnace, the different parts can be otherwise.
