At present, infrared temperature measurement systems have been widely used in various occasions in metallurgical production lines. However, when measuring the temperature of slab in continuous casting machine in the second cooling zone, the problems of measurement accuracy and system reliability always exist.

Hot blast furnace is a heating and blowing equipment for blast furnace (high furnace), it is an indispensable part of modern blast furnace.

Single crystal silicon is widely used in various fields such as semiconductors, solar cells, integrated circuits, and discrete components. Polycrystalline silicon is a raw material for the production of monocrystalline silicon, and the purity of monocrystalline silicon is much higher than that of polycrystalline silicon.

Polycrystalline silicon is a form of elemental silicon, and its purity is lower than that of monocrystalline silicon. It can be used as a raw material for pulling monocrystalline silicon. Polysilicon is produced by a polysilicon ingot furnace.

To measure temperature of slab surface by an infrared temperature sensor. The oxide layer, water vapor and dust on the surface of the slab increase the difficulty of measurement. The temperature of the oxide layer surface cannot represent the actual temperature of the slab.

When measuring the temperature of square billet, billet, steel plate, steel bar, etc. at the rolling mill position by an infrared pyrometer. The industrial site environment is harsh, dust, water vapor and other factors will affect the accuracy of temperature measurement.

---

Use an infrared pyrometer to measure the temperature of the rod and wire. During the measurement, the target moves quickly, the target is jittery, the surface condition is uneven (such as rebar), and it may measure small targets (such as 5mm).
