No, it won't work for several reasons. They are really only good on solid dark things and below 900°F/480°C. I have a vr=ery expensive lab IR pyrometer and never could get a reliable reading in the forge or on red hot steel.
A TC and simple reader/PID will work fine. Use an 8 to10 gauge type K TC in a ceramic tube sheath. Any cheap PID will work as the reader. Make sure you use type K wires and hook them up with matching polarity.

The search words for the parts needed would be:
PID controller
type K kiln thermocouple 8-gauge
ceramic thermocouple sheath tube
type K thermocouple connection block
type K thermocouple wire
Check the items you find in these searches for price. Some come up ridiculous. The total for all should be around $100 max. For example, the TC block will show at $100 on one site and $8 on another. Amazon and eBay are good sources. Often the parts can be bought as a kit for as low as $80. The kits unsulky include the SSR and heat sink, which you don't need to use as a read-only pyrometer, but they may become useful if you set the PID up to control the forge temperature.

Or, you can get a pyrometer setup with the parts for reading temperature and add the TC sheath. A sheath is not needed in an electric kiln or tempering oven but is necessary in a forge because of the flames.
Try this search :
For almost nothing you can get a 4-channel basic reader and add the TC probes and keep track of the forge, quench oil, temper oven, and room temp by adding the TCs . Except for the forge, the other ones can be the cheap type K TCs. Search this:
