Embodiment Construction

[0028] The invention concerns the production and, if necessary, the processing, of a metal plate 10 provided or capable of being retrofitted with at least one embedded temperature sensor. During the production of the metal plate 10, a number of steps not mentioned in the introduction have to be carried out, which are common in the prior art to produce diffusion bonding between metals, such as cleaning the metal surface, thermally exposing the plate body Pretreatment, and rolling of the plate body to achieve interdiffusion bonding, and post heat treatment (if required). Although these additional steps are not described here, it should be noted that if the plate bodies made of aluminum or aluminum alloys are joined to each other by the method according to the invention, preferably by rolling, the surface of each aluminum layer They are heated to a temperature above the recrystallization temperature of aluminum but below the melting point of aluminum before being pressed together...

Abstract

The invention relates to a method for producing a metal plate having at least one embedded temperature sensor and to a metal plate produced by the method. The metal plate is produced from a pluralityof layers or plate bodies, which are diffusion-connected to each other by thermal pre-treatment and subsequent rolling. A sheathed thermocouple (24) is rolled, as the temperature sensor, into the metal plate during the production of the metal plate, or a protective tube (21) made of metal is rolled into the metal plate, into which protective tube a sheathed thermocouple (24) can be inserted afterthe metal plate has been processed further to form a cooking vessel (22).

Description

technical field [0001] The invention relates to a method for producing and, if necessary, processing, a metal plate provided or capable of being retrofitted with at least one embedded temperature sensor. [0002] The invention also relates to a metal plate produced by this method and which is provided or can be retrofitted with at least one embedded temperature sensor. Background technique [0003] A similar method is known from document EP 2 525 938 B1. In a metal plate produced by this known method, the metal plate comprises, in addition to an embedded heating element, an embedded temperature sensor with a prominent measuring head from which two wires extend to the metal outside of the board. A temperature sensor with a distinct measuring head should consist of a ceramic body in which the electrical circuit of the temperature sensor is embedded. Due to the ceramic body, one or more plate bodies made of aluminum or an aluminum alloy need to have recesses for the ceramic ...
