1 Scope

GB/T 10067.412-2015 is the Chinese national standard on basic specifications for electroheat installations - part 412: box-type quenching furnaces, 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 11 September 2015 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 April 2016. Classification: ICS 25.180.10, CCS K 61. 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 general technical requirements for box-type quenching furnace products, test methods, inspection rules, marks, packages Equipment, transportation, storage, and ordering and delivery. This section applies to a controlled atmosphere, all kinds of laboratory and industrial in the range of 750 °C \u200b\u200b~ 1100 °C with a box-type quenching furnace. Mainly used Steel parts carburizing, carbonitriding, carbon complex, bright hardening heat treatment process. This section also applies to a similar box-type hardening furnace, the different parts can be otherwise.
