The invention discloses a thermocouple-buried temperature test method in a small square billet high temperature heating process, which belongs to the field of metallurgical technology. The test method comprises the following steps: a) drilling and tapping are carried out at a corresponding place of a to-be-tested billet; b) a tester thermal protection device internally provided with a temperature tester is fixed at one end of the billet; d) a hollow connection bolt is arranged at the drilling and tapping place of the to-be-tested billet, an armored thermocouple is inserted in the center hole of the hollow connection bolt via a locking nut and an axial sealing spring respectively, and the armored thermocouple is fixed in the to-be-tested billet through fastening the locking nut and is connected with the temperature tester; f) the to-be-tested billet is put in a furnace for being heated; and e) after heating is over, the temperature tester is taken out, and data are read. A quick armored thermocouple mounting method and a small thermal protection device are designed, the method of the invention thus can be effectively applied to a heating furnace with a small effective furnace door opening in a high speed wire rod factory, and influences on the billet temperature test precision by furnace gas fluctuation, a gap and the like.
Description
technical field [0001] The invention belongs to the technical field of metallurgy, and relates to a temperature testing method in the heating process of a billet, in particular to a buried-couple temperature testing method in the high-temperature heating process of a small-sized square billet. Background technique [0002] As a widely used pre-rolling heating equipment, the steel rolling heating furnace accounts for 60% to 70% of the energy consumption of the steel rolling process. Therefore, the energy consumption of the steel rolling heating furnace has always been a concern of people. At the same time, a comprehensive grasp of the temperature change of the billet in the heating furnace is a necessary condition for rationally formulating the heating system and optimizing the heating process. Therefore, it is particularly important to fully grasp the real-time temperature distribution of the heating furnace and the billet in the heating furnace. It is the starting point for...
