1 Scope

GB/T 10067.31-2013 is the Chinese national standard on basic specifications for electroheat installations - part 31: medium frequency coreless induction 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 19 July 2013 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 2 December 2013. 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 intermediate frequency coreless induction furnace (hereinafter referred to as intermediate frequency coreless furnace) product classification, technical requirements, test Methods, inspection rules, marking, packaging, transportation, storage, and ordering and delivery and so on. This section applies to a frequency higher than the frequency 50Hz, less than or equal to 10000Hz, the rated capacity within 0.01t ~ 120t range from IF frequency semiconductor device powered smelting ferrous and nonferrous metals and alloys coreless induction melting and holding furnaces.
