Measurement of the forming temperature during forging of metals: steel, iron  alloys
When industrial forging metal components mainly for shipbuilding, automotive, aerospace, mechanical engineering  plant construction are made, for example in so-called forging. Using the non-contact temperature measurement, the correct shaping temperature of steel, iron,  their alloys are checked when hot forging.

锻造中的正确温度是决定性的质量因素之一

Because the temperature of the workpiece before forging is one of the most important parameters  thus decisive for the quality in the production of many safety-related components. The temperature is depending on the material  process between 950 °C  1250 °C. The forged blanks are preheated to gas-fired  induction heated furnaces  therefore can  be measured directly with conventional thermocouples. For gas stoves only the internal temperature of the furnace is measured, but  the workpiece itself. In inductively heated furnaces also thermocouple measurement does  apply.

That is the reason why it is essential to check the work pieces for the correct forging temperature directly at the exit of the furnace with pyrometers before it will be taken into the forging press. These pyrometers must have a very short response time, very small spot sizes,  a peak picker as the parts are always moving. Only the combination of these 3 properties enables a very exact measurement even if the work piece has scale on the surface.
